[Reviewed]In this study, we conducted bicycle riding experiments that focus on the method of information presentation by an automated system to cyclists, with the intent to design an information system related to bicycle safety information. In an evaluation of information presentation, we confirmed that auditory presentation was the most effective from the viewpoints of both recognition and comprehension. In addition, information presented using the auditory method was more likely to be recognized than information presented using the visual and tactile method combined. The results of the analysis of variance for recognition showed that the visual presentation method had no significant effect. In addition, the experiments involved behavioral observation using the system and a questionnaire survey on changes in behavior before and after experiencing the system. The results showed that information was correctly conveyed by the system using a combination of auditory, tactile, and visual presentation methods, regardless of the users' degree of awareness of the system. Two weeks after the experiment, a survey was conducted to investigate the changes in the participants' awareness and behavior regarding risky or illegal riding. The results showed an improvement in the awareness of risky or illegal riding in daily life and an increase in right behavior, confirming the effectiveness of this system. Consequently, the results demonstrate the effectiveness of the system and provide knowledge for realizing a bicycle riding safety support information system.

[Reviewed]This paper proposes a method for identifying the bicycle riding environment using only onboard equipment. Initially, a fundamental subsystem is established for identifying the bicycle riding environment, and its functionality is validated. The findings indicate that the subsystem, utilizing an open-source trained model, can detect riding on roadways but not on sidewalks. Consequently, we emphasize the need for transfer learning, specifically using sidewalk viewpoint images, to enable the identification of bicycle riding environments. Subsequently, we conduct bicycle riding environment identification by employing a transfer learning model with manually labeled training data. The results demonstrate that after transfer learning, sidewalk riding detection, which was previously unachievable, becomes feasible. The identification rate was over 80%. Furthermore, we develop four riding environment identification algorithms, including the transfer learning model, and compare their performance across various road environments and riding conditions. Consequently, it is established that the region of interest (ROI) extension identification algorithm exhibits the highest identification performance (93% on average). As a result, this paper contributes valuable insights into the realization of bicycle riding environment identification, particularly in the context of detecting traffic violations within the riding safety support information system.

[Reviewed]In Asian megacities, behind wide streets accessible by car, there are areas of narrow streets that are inaccessible by bus or car. This study investigates measures to improve access to bus stops in Hanoi from the perspective of the neighborhood environment of these residents. These results are expected to contribute to solving similar problems in Asian megacities. The survey divided residents into two groups, one group living on wide streets and the other group living on narrow streets in Hanoi, then obtained and analyzed data on their attitudes towards walking to bus stops through a questionnaire survey. The results revealed the following. The distance to the bus stop was accessible for both groups. Between the two groups, the attitude towards walking to the bus stop is more influenced by the location factor than the occupation (employee or student). Factors such as the benefits of walking, infrastructure, and security conditions play an important role in the decision to walk to the bus stop during the daily commute.

[Invited]Herein, we propose a “Comprehensive Road Safety Management for School Routes” to realize “Vision Zero for School Routes”, launched by International Association of Traffic and Safety Sciences (IATSS). Specifically, we discuss Niigata City's “Vision Zero” project rolled out at Hiyoriyama Elementary School, which aims to eliminate accidents resulting in deaths of or serious injuries to children. Hiyoriyama Elementary School was to be opened by merging four elementary schools in Chuo-ku, Niigata City, and traffic safety measures were discussed with the participation of local residents to ensure the safety of the new route to the school, which would bring in many children from a wide range of localities. In a workshop attended by road administrators, police, school officials, and local residents, issues were identified, a traffic survey was conducted to understand the current situation, and a traffic simulation was conducted to verify concerns that might arise subsequent to the implementation of traffic control measures. The traffic in front of the elementary school was restricted during school hours; furthermore, to ensure compliance with these restrictions, rising bollards were installed for the first time along a school route in Japan. We also clarified the long-term effects of the rising bollards installed on a public road in Japan for the first time in an IATSS project. We hope that this report contributes to the expansion of Vision Zero, which secures the safety of schoolchildren.

[Reviewed]In rapidly urbanizing regions of low- and middle-income countries as found in Asia, transportation management faces significant challenges, particularly with the popularity of two-wheeled vehicles. While these vehicles offer convenience in Asian megacities, their increasing prevalence has led to many urban traffic issues, including air pollution and traffic management problems. Consequently, several countries have contemplated or implemented bans on motorized two-wheeled vehicles in urban areas. With a forthcoming ban on motorcycles in 2030, this study investigates potential switches in transportation travel modes among motorcyclists. Analyzing factors influencing choices between electric bicycles (e-bikes) and buses, the results indicate a probable widespread adoption of e-bikes over buses post-ban. Income, place of residence, and access to bus stops emerge as key determinants.

Introduction: One of the significant characteristics of schools in Vietnam is that almost all parents send their children to school and/or pick up their children from school using private vehicles (motorcycles). The parents usually stop and park their vehicle on streets outside the school gates, which can lead to serious congestion and increases the likelihood of traffic accidents. Methods: The objective of this study is to find out factors affecting the picking up of pupils at primary school by evaluating the typical primary schools in Hanoi city. A binary logistic regression model was used to determine factors that influence the decision of picking up pupils and the waiting duration of parents. The behavior of motorcyclists during the process of picking up pupils at the primary school gate has been identified and analyzed in detail by the Kinovea software. Results and Discussion: The study showed that, on the way back home, almost all parents use motorbikes (89.15%) to pick up their children. During their waiting time (8.48 minutes in average), they made a lot of illegal parking actions on the street there by, causing a lot of “cognitive” errors and “crash” points surrounding in front of the primary school entrance gate. Risky picking-up behaviors were significantly observed, i.e. picking-up on opposite side of the school, making a U-turn, backing-up dangerously, parking on the middle of street, and parking on the street next to sidewalk). Conclusion: Based on the analyzed results, several traffic management measures have been suggested to enhance traffic safety and reduce traffic congestion in front of school gates. In addition, the results of the study will provide a useful reference for policymakers and authorities.

In some circumstances on streets equipped with new bike facilities, cyclists are not interested in using them. Instead, they continue to use shared spaces with pedestrians or motor vehicles. Thus, simply adding a bike facility does not guarantee that cyclists will switch to using it. Owing to the considerable development of bike facilities, the investigation of facility preference, particularly focusing on facility choice forecast, has become increasingly important. This study developed a model for predicting the facility choice of cyclists between on-street facilities (curb, traffic lane, and bike lane (BL)) and off-street facilities (sidewalks). Initially, the optimal model was selected using Bayesian Model Averaging method. Then, it was validated by both internal and external validations. Apart from the aforementioned factors, several other exogenous variables were also found to be significant predictors of bike facility choice, including the width of traffic lanes, existence of real-time stopping vehicle, type of bike, bus stop existence, and in-group cycling. Analysis of the relative importance of predictors indicated that bus stop existence, effective sidewalk width, and type of bike were the potential predictors. A framework for predicting BL usage, if it is present, was also developed. A test for the predictive performance of the application at a real site was carried out. By comparing predicted and actual BL usage figures, the analysis showed good predictive performance. The results of this study can help developers, planners, and designers to adopt reasonable investment decisions as well as better designs in developing new bike facilities.

This paper describes designing a new pedestrian navigation system using a comprehensive framework called the pedestrian navigation concept reference model (PNCRM). We implement this system as a publicly-available smartphone application and evaluate its positioning performance near Omiya station's western entrance. We also evaluate users' subjective impressions of the system using a questionnaire. In both cases, promising results are obtained, showing that the PNCRM can be used as a tool for designing pedestrian navigation systems, allowing such systems to be created systematically.

Left- and right-turning vehicles are allowed to make a turn through the crosswalk allocated for pedestrians to cross the road safely. When drivers share this space with pedestrians, they are expected to travel at a low or near-walking speed. Before approaching the crosswalk, left- and right-turn drivers must adapt their speed so as to not endanger the pedestrians. This article presents a study comparing the effectiveness of brick and red-colored pavement on changing the speed of the driver when they make a turn through the crosswalk at a signalized intersection. Three intersections with different pavement design scenarios (no pavement design, brick pavement, and red-colored pavement) were selected for the field study. The speed at three situations—free flow condition, at yellow onset, and when accepting the gap with a pedestrian—were analyzed to evaluate the speed behavior. This data were analyzed using multiple linear regression. Results show a positive effect of brick pavement on the crosswalk on reducing a driver's speed in left and right turns.

Recently, great effort has been made to increase bicycle ridership, however the high vulnerability of cyclists to road accidents has been a big deterrent preventing citizens from cycling. Among the causes of bicycle accidents, the loss of control due to inadequate handlebar control is a particularly common one. So, investigation of handlebar controllability (HC) is an important part in finding ways to deal with this type of accident. In this study, HC was examined considering the effect of pavement roughness level and the interaction effects of Age and Gender. The results showed that cyclist’s HC was negatively affected by pavement roughness level. The examination ofthe interaction effect of cyclists’ age on the correlation between HC and pavement roughness level indicated that elderly cyclists generally suffer more from the effect of pavement roughness on their HC, compared to younger ones. Especially, as they get older, the effect of pavement roughness on their HC even becomes greater. The interaction effect of Gender was found not to be significant. The results of this study could help in proposing countermeasures to deal with accidents resulting from loss of control and it may also serve as a basis for further studies on the potential field of HC.

Travelers’ behavioral intention and habits are well-known constructs in the literature of travel behavior. In general, behavioral intention and habits explain the deliberate process and the habitual process of travelers’ behavior, respectively. While behavioral intention is considered as a goal-dependent deliberation, habits are not fully defined due to different views of researchers. The stimulus-response approach describes habits as a goal-independent automaticity, whereas the script-based approach views habits as a goal-dependent automaticity. The controversy in understanding the association between goals and habits necessitates a focus on the establishment of habits in which habits are assumed to appear due to a repetition of behavioral intention. With an aim to understand the process of transformation from intentions to habits, this study focuses on a mediated form of intention that is close to habits. It is hypothesized that the mediated form has characteristics similar to those of habits. Empirical support for the hypothesis was obtained in public transportation domain. The findings of this study are important for the field because they present a possibility that past research has investigated the mediated form of intention instead of habits.

Pedestrians are the most vulnerable road users as they are more exposed than other road users. Pedestrian safety at road intersections still remains the most vital and yet unsolved issue. One of the critical points in pedestrian safety is the occurrence of accidents between left-turning vehicle and pedestrians on crosswalks at signalized intersections. A crosswalk is a place designated for pedestrians and cyclists to cross vehicular roads safely. Drivers are expected to give priority to pedestrians or cyclists during interactions between them on the crosswalk. If a driver exhibits non-yielding behavior, the interaction will turn into a collision. This study examined the safety effect of three crosswalks designed with different materials such as red-colored material or brick pavement based on a safety performance study. The safety performance study considered left-turning driver's gap acceptance behavior and the severity of traffic conflict events between left-turning vehicles and pedestrians. The results of the study indicates that using brick pavement on a crosswalk increases the safety level of the crosswalk. Drivers at such crosswalks are more acquiescent to the priority rule.

The literature on psychological studies includes numerous documented efforts to explain traveller behaviour under the pro-environmental approach. However, this approach was found to perform weakly compared to the self-interest approach. A review of the pro-environmental approach showed that the existing pro-environmental models generally discussed travellers' mode-use obligation under a narrow background of environmental awareness. This would probably lead to results showing no difference in mode-use obligation between private vehicles, which have environmental concerns, and public vehicles, which have both social and environmental concerns. In addition, findings of non-mode-choice studies have suggested that awareness of social value would likely be involved in deciding pro-environmental behaviour. As such, it was suggested that social-awareness factors may influence travellers' obligations to transportation modes. However, it was surprising that the literature on mode-use behaviour showed few efforts aimed at the impacts of social-awareness factors on travellers' mode-use behaviour. This study, therefore, provided an examination of the necessity of expanding travellers' mode-use obligations towards social-awareness aspect by considering various social awareness factors in the mode-use model. Empirical results from 333 respondents in Hidaka City, Japan, showed support for the expansion of the travellers' obligations through observation of novel social-awareness factors, including social-awareness of consequences and perceived service interruption, as predictors of bus use intention.

本研究では、交通不便地域における、1 年間のコミュニティバスのテスト運行を対象として、コミュニティバス導入による住民生活の質の変化について検証した。対象地域住民の移動は自動車に大きく依存していること、若年層では路線バスに対する満足度が低いにもかかわらず路線バスを利用していること、地域の交通問題が進路選択の障害になっている可能性のあることが示唆された。コミュニティバスのテスト運行前後に実施した調査からは、バス利用者の多くが普段の生活の移動で送迎されていることが分かったが、バスの行き先やダイヤに関するニーズの違いから、コミュニティバスの運行によって送迎の必要が解消されていないことが分かった。一方、個人への継続的なダイアリー調査から、一部の送迎が必要な移動が、コミュニティバスにより代替される可能性は見られた。長期的にみた意向からは、コミュニティバスの導入により生活面での変化があると考えている住民もいることから、住民のニーズを詳細に反映したバス運行計画を立てることで、住民の生活の質の向上に貢献することが示唆された。At present, community bus is spread in suburban areas. Community bus may have a big impact on lives of local residents. In this study, the authors focus on the impact of a community bus on the lives of local residents. The authors conducted surveys in a case study area, Kawajima town in Saitama prefecture, where a community bus was introduced from December 2013 to December 2014. From the result of a survey in 2012, it was found that young residents in the case study area relied on local bus service but they were not satisfied by the bus service. Furthermore, more than 50% of third-year junior high school students had changed high school to go because of issues related to transportation problems. From the result of surveys conducted before and after the introduction of the community bus, no clear effect was found for the residents' quality of life. The community bus did not reduce pickup and drop-off by family members. However, there was a possibility that a student activity that needs her family support was helped by the community bus. The community bus may improve residents' quality of life if the service is suitable for their needs.１．はじめに１－１．背景と目的１－２．既存研究の整理と本研究の位置付け２．研究方法２－１．研究方法の概要２－２．ケーススタディ地区の概要２－３．コミュニティバス導入の概要２－４．町民アンケート調査の実施３．分析結果３－１．ケーススタディ地区の問題把握３－２．コミュニティバスの効果分析３－３．ダイアリー調査・ヒアリング調査の分析４．まとめと今後の課題

Recently, the number of bicycle accidents are increasing with the increasing population of cyclists. In particular, the accidents of the elderly and women riding with an infant are outstanding. The authors thought that is caused by instability when starting partly. Then we focused on the full electric bike which is one of the electric two-wheeled mobility. In Japan, the full electric bike isn't treated as a bicycle by the law, but it has the potential to run safer than the conventional bicycle because it can run only with a throttle and diminish the wamble when starting. Then, we conducted experiments about the safety and comfort of the full electric bike and did a comparative analysis with the regular bike and the electric assisted bicycle. In the result, it was revealed that full electric bike is more stable and run more comfortable than the other two bikes. On the other hand, it was revealed that there are some problems such as the weight of the full electric bikes.

The authors investigated the phenomenon of “intelligent rat-runners”—that is, road drivers that use car navigation systems to drive through residential areas in order to avoid congested traffic on arterial roads. A nationwide questionnaire survey revealed that some of such drivers, as a result of having to look at the displays of their navigation systems, have had experiences that could have resulted in serious accidents. A driving experiment conducted showed that drivers with access to information about narrow streets and route guidance through their navigation systems have a greater tendency to avoid congested arterial roads by turning into residential areas.

With the aim of identifying typical characteristics of travellers, traditional segmentation approaches were based on socio-demographic variables. However, the approaches could not reveal the factors motivating individual behaviour. This result led to an emerging interest in psychological research models that are adhered to the decision-making process. Among various related theories, the concept of loyalty was attractive because the major purpose of establishing a loyalty concept is to recognise a customer's pattern towards a given service. However, there were few efforts aimed at determining market segments based on a loyalty framework. In addition, there was no consensus achieved on theoretical loyalty typology due to different empirical findings in different market contexts. This study aims to be the first loyalty-based attempt to provide an operational method of segmenting bus service market. Seeking practical implementation, another focus of this study is to determine typical characteristics of the market segments. Analyses that included cluster techniques were conducted on questionnaire data collected from 333 respondents in Hidaka city, Japan. A cross-classification between relative attitude and service patronage was successfully established, dividing the market into four segments. Segments of loyalty and no-loyalty were observed to be dominant over the remaining market. In contrast, the spurious loyalty segment was small and insignificant. An expansion of the latent loyalty segment was also observed when moving from the intention phase to the actual behaviour phase. Notably, not only demographic factors but also social awareness variables including environmental concern and elderly support were observed to be significant in distinguishing customer segments from one another. © 2013 International Association of Traffic and Safety Sciences.

本研究では、社会心理学の知見を応用したコミュニケーションを中心とする交通政策である、モビリティ・マネジメント(MM)を用いた速度MMを提案し、社会実験によりその効果を検証した。速度MMではパンフレットとアンケートをドライバーに直接配布する自覚促し実験と、路上での速度表示実験を行った。実験で回収したアンケートから、多くのドライバーにとって速度MMは実施後の走行において周囲への影響を考慮するきっかけとなったことがわかった。また速度抑制効果は実験1ヶ月後まで見られた。これらの結果より、MMを用いた交通静穏化施策の速度抑制効果を確認できた。In this study, the authors proposed "speed control MM", a new traffic calming measure that used methods of Mobility Management (MM), which is a transportation measure using knowledge of social psychology. The purpose of this study is to verify the effect of the traffic calming measure using MM. The authors conducted a social experiment; in the experiment, two communication tools: a pamphlet and questionnaire sheet, were distributed to car drivers. In addition, car drivers were displayed their driving speed. The result of questionnaire survey revealed that most of drivers recognized that speeding is a nuisance to the neighborhood by the communication tools. From a speed survey and the speed controlling effect of "speed control MM" was found.1 背景と目的2 既存研究と本研究の位置付け3 対象地区の概要4 速度MMの概要5 速度MMの交通静穏化効果6 まとめと今後の展望

In recent years, the improvement of walk space and the necessity for maintenance of the pedestrian space has been recognized. However, the evaluation methods for walk spaces have not been well established. This study is intended to obtain basic data to establish the evaluation index of the walk space using the pedestrian facial expression and behavior. When it changed the driving condition of cars, a constant tendency was seen in smile and behavior of the subjects. And it was shown that there was a relativeness between the pedestrian affects and visible characteristics. Furthermore, through pedestrian observation in actual road, the frequency of pedestrian smile increased and their behavior showed relaxed states at the vehicle- free street.
Therefore, it was revealed that smile and behavior showed a constant tendency for the psychological condition, and obtained the result that can expect for a new evaluation index of the walk space.

The rat-run traffic flowing into the community road is a big problem in terms of traffic safety. Physical device, such as a constriction or hump have been used in the existing measures. However, these measures can't remove only rat-run traffic from community road. It is not a fundamental solution of the problem. Therefore, we focused on the rising bollards that are popular in Europe. The Rising Bollard can make it pass only vehicles with authority by making it go up and down the bollard made of steel automatically. It has not been introduced yet on public roads in Japan.
For the purpose of accumulation of the results of basic study of Rising Bollard, we conducted experiment in Saitama University campus in order to examine the possibility of installation in Japan. From experiments with subjects, inhibitory effect on passing the road is evident. This showed the efficacy against rat-run traffic. In addition, it was confirmed the operation in a bad situation, such as rain and snow and also confirmed the safety at the time of contact with the vehicle. It was possible to get useful knowledge for the installation.

In this study, traffic accident factors at crossings of community roads and arterial roads were analyzed. The authors supposed that if a community road were severed by an arterial road that was built after the community road was built, "the neighborhood DNA", which is a local characteristics, enhances the risk of the crossing. "the neighborhood DNA" means a habit with the residents in the neighborhood to across an arterial road at a such crossing. The authors define a crossing that was made by an arterial road dividing a community road as a neighborhood DNA type crossing. In the analysis, sudden brake outbreak point data, which were provided from Honda R & D and traffic accident data from Saitama Prefecture Police were used. This study conducted two analyses; one was an analysis on the traffic accidents and the other was an analysis on sudden breaks. In conclusion, it was suggested that neighborhood DNA type crossings are dangerous.

Intelligent rat-runner: Impact of car navigation system on safety of residential roads Aya Kojima; Susanne Elfferding; Hisashi Kubota
19th Intelligent Transport Systems World Congress, ITS 2012, 2012
In this research, the authors investigated the phenomenon of "intelligent rat-runners"-that is, road drivers that use car navigation systems to drive through residential areas in order to avoid congested traffic on arterial roads. A nationwide questionnaire survey that was conducted by the authors established this trend and also revealed that some of such drivers, as a result of having to look at the displays of their navigation systems, have had experiences that could have resulted in serious accidents. Moreover, a driving experiment conducted showed that drivers with access to information about narrow streets and route guidance through their navigation systems have a greater tendency to avoid congested arterial roads by turning into residential areas than do drivers with access to only one of these kinds of information. These findings indicate a need for the improvement of car navigation systems so that they do not encourage rat-running.

This study proposes a “soft” measure, “the Rat-runner MM (
Mobility Management),” against through traffic problems that is implemented by residents, and analyzes its effectiveness. The authors conducted a social experiment along a residential street with heavy traffic. Communication tools developed with socio psychological knowledge were distributed to rat-runners. From the questionnaire survey, it was found that the communication tools distributed during the experiment made the rat-runners aware that through traffic causes nuisances to neighborhoods. A follow-up survey conducted one month after the experiment showed the rat-runners' improved behavior. Meanwhile, traffic volume on the residential street decreased by about 10% after the experiment. An attitude survey conducted for residents found that the Rat-runner MM did not face any resistance unlike other hard measures that were proposed for implementation along the residential street.

Traffic calming schemes are gradually becoming more widespread means of addressing concerns in residential streets. Although there has been a lot of recent research investigating the traffic calming programs, little research has been devoted to examining its decision making process. Asian countries for example Japan and Korea have introduced several traffic calming devices but they have no distinct and methodical study procedure. The objective of this research is to illustrate a comprehensive review of North American traffic calming decision making process practices. The scope of which is to serve as a basis for establishing the process guiding principle to introduce in Asian countries. This research reveals that most of the cities are having a warrant based system to check the suitability of traffic calming device. The result shows that the budget constraint is the most important reason to prioritize traffic calming projects while political intervention is the main drawback of the process.

Traffic calming provides a process for identifying and addressing existing problems related to speeding, excessive traffic volume, and pedestrian safety concerns on residential streets. Although several traffic calming devices have been installed in Asian countries for example in Japan and korea; they have no distinct and methodical process for the device selection. The objective of this research is to illustrate a comprehensive review of North American traffic calming device selection process practices. The aim is to establish traffic calming device selection process guiding principles to be introduced in Japan. This research reveals that speeding is the most significant issue for installing a traffic calming device. The result explores that community support is the most important factor for the selection of a traffic calming device. The result shows that speed humps and speed tables or raised crosswalks are the most widely practiced devices.

The decline of response rates in attitude surveys and the nonparticipation of residents are big issues in decision-making processes for transportation planning. The existence of individuals who do not state their opinions, the silent group, disrupts smooth consensus-building processes. It is often claimed that the silent group or so-called silent majority relies on policy makers or proposed plans. This research analyzes the silent group's character in a traffic calming project conducted in a residential area. To understand the silent group's level of awareness, attitude, and preference would help identify better ways of including them in planning processes in the future. Data obtained from questionnaire surveys were used for this analysis. Nonrespondents to the surveys were defined as the silent group. First, the difference of opinions between the silent group and the nonsilent group was investigated. The result showed that the silent group was less aware of the traffic situation in the area and did not easily agree with the proposed plans. Second, the reasons for the silent group's attitude were analyzed. The result suggested that the silent group members felt less danger on roads near their houses, so they do not recognize the traffic situation of the whole neighborhood as serious. Because of the lack of awareness, the group tended to refuse questionnaire surveys. Moreover, the logistic regression analysis concluded that the silent group was less involved with survey topics that dealt with specific traffic problems and countermeasures.

There are no specific measures to formulate public opinions and no clear guidelines for positions of people who do not express their opinions, whom the authors call the "silent group," in any planning processes. In this research, the authors analyzed a relationship between a silent group and their involvement with topics of questionnaire surveys for a micro area transportation planning. In conclusion, the authors found that a silent group's involvement with the topics shown in the questionnaires such as traffic problems in their residential area was weaker than that of people who responded to the questionnaires in time. If people thought that one of the questionnaires picked up only roads they didn't think danger, they tended to be silent despite their recognition of danger in the whole area.

[Invited]Until now, the challenge of having to share restricted space on roads has been addressed by a diverse group of stakeholders, with people offering their expertise to solve the problem. In recent years, new modalities of mobility have been emerged, and the manner in which spaces are shared will need to be explored. With regard to the concept of “shared space” that was conceived from the idea of achieving safe roads through minimizing traffic rules, eliminating the segregation of pedestrians and vehicles, and improving attentiveness to subjects of transportation, this paper looks at the circumstances surrounding shared spaces on roads, while looking at case studies where pedestrian safety and comfort have been prioritized on a wide scale.

In this paper, the authors propose “rut runner MM” as a communication method to reduce through traffic by residents' power. As a result of a social experiment conducted in a dangerous urban street, it was found that the traffic volume had reduced by about 10%. It was also found that this effort was not suffered from opposition from other residents proving the effectiveness as a community participation measure.

This study focused on the effect of sports on prevention against traffic accidents involving old people. We conducted a questionnaire survey for 2,453 respondents who were 65 old or older than 65, and 200 of them have not done any sports and the others do exercises or one sport. The result suggested that seniors doing some types of sports tend to take appropriate action to avoid traffic accidents. We also conducted an experiment using a simulation machine for crossing zebra on a road. The subjects are old people who play tennis and who do not do any sports, and university students: all the subjects were men. The result of the experiment showed that old people who playing tennis more frequently turned their head to right and left to see vehicles during they were crossing the road in the simulation machine.

Currently, traffic simulation does not reflect day-to-day traffic flow change. In this study, we focus on the day fluctuation data. We clarify that the relationship between the traffic situation day fluctuations and traffic simulation may reproduce the day fluctuation of traffic flow. In addition, we discuss the possibility whether day fluctuation data can become an alternative to conventional traffic survey data. By using day fluctuation data and conventional traffic survey data, it was possible to clarify the change of day traffic situation and the positioning of the traffic survey date. Furthermore, we were able to propose a method for daily fluctuations reproduction. Future, by increasing car probe data, and by making frame that integrates the day fluctuation data each company owns, the method contributes effectively.
