Promoting public transport use is expected to contribute to reducing CO2 emissions in the transport sector. Using Okayama City and Central Tokyo as representative case studies of regional and metropolitan areas in Japan, this study examines the impact of the evaluation of the ‘hard’ and ‘soft’ attributes of rail and bus services on the overall evaluation. This study then explores the relationship between the overall evaluation and usage frequency of rail and bus services, as well as the relationship between the usage frequency and travel-based CO2 emissions from private transport modes. Furthermore, this study investigates whether the emissions cause differences in the evaluation of the ‘hard’ and ‘soft’ attributes of public transport services. The findings suggest prioritising an improvement in ‘hard’ rather than ‘soft’ attributes in order to reduce emissions through the use of public transport in regional areas. However, in metropolitan areas, no relationship was found between the evaluation of public transport services and emissions, presumably because of the lower ownership rate of private cars that residents can use freely and the markedly higher level of rail and bus services. This study provides a methodological reference for analysing the potential to reduce travel-based emissions from private transport modes by enhancing public transport service contents.

Study of Effects of the Pedestrian’s Standing Position and Behavior at Unsignalized Crosswalk on the Driver Yielding Reviewed

In 2021, approximately 70% of traffic accident fatalities at pedestrian crossings were caused by drivers violating pedestrian crossing laws, indicating that pedestrians are not always given priority at pedestrian crossings. In response to this situation, the police have been stepping up enforcement, but the effectiveness of such measures is thought to be limited. In this study, we conducted a survey focusing on the standing position and behavior of pedestrians while waiting to cross the street, based on the idea that if pedestrians could clearly communicate their intention to cross the street to drivers, it would be possible to improve the rate of driver’s yielding. As a result, it revealed that standing position has more influence on the yielding rate of cars than behavior while waiting to cross the street. The study also suggested that the effects of standing position and behavior on the yielding rate could be enhanced if drivers were unable to take evasive action.

A Study on Bicycle Behaviors at Intersections with a Stop Sign in Daily Bicycle Use Reviewed

HASHIMOTO Seiji, YADA Atsushi, UNO Haruka, HAGIWARA Yoshiyuki, HORI Hirofumi

JSTE Journal of Traffic Engineering 8 ( 4 ) A_1 - A_8 2022.4

In Japan, about 60% of bicycle-related accidents occur around intersections every year, and accidents at intersections have become a problem because of violations of laws and regulations by bicycle users. In addition, the "Guidelines for Creating a Safe and Pleasant Environment for Bicycle Use" issued in 2012 states that it is important to grasp the road space and actual conditions of bicycle use in order to formulate a bicycle network plan. In this study, behaviors of bicycle users were recorded by using GPS data, and the relationship between their behaviors at intersections with a stop sign and the road elements at the intersections was examined. First, the rates of stopping and slowing down at the intersections were calculated to grasp the actual condition. Moreover, multivariate analyses were conducted on the compliance to stop and slow down, the passing speed at the intersection, and the deceleration rate just before the intersection, and the factors that are thought to affect each behavior were clarified.
