This paper analyzes the implementation of Japan's and Indonesia's national frameworks aiming to promote sustainable urban mobility by placing transport policy coordination as pre-requisites under the decentralization regime. It takes two cities, Matsuyama and Yogyakarta, as the case studies. The analytical framework developed here highlights multi-level government coordination, coordination among local stakeholders, and regulator–operator coordination. The analysis is based on policy documents review, field observation, hearing and a questionnaire survey. The study shows some good practices as well as drawbacks of the schemes and produces lessons-learned from Japan's ‘omnibus town scheme’ to improve Indonesia's public transport program and for other cities in developing countries. 相似文献

One of the most critical reasons for accidents involving pedestrians in signalized urban intersections is their violations regarding running red lights. Therefore, studying the essential factors in this issue is of interest to researchers. This research aims to evaluate the external factors affecting the pedestrians' violation, specifically, factors regarding the geometrical design and traffic situation. Cameras recorded the behavior of 1590 pedestrians in 10 crosswalks of 6 intersections in Mashhad. Afterward, the effect of 12 distinct variables for each pedestrian was assessed. To analyze the data, SPSS was used in combination with binary logistic regression. Out of the nine variables participated in the model, “traffic volume”, “the number of violators”, “length of the crosswalk”, “red light duration”, and “physical movement problems” affect the pedestrians' decision to comply with or violate a red light. The analysis shows that with an increasing number of vehicles, the probability of violation would reduce by 9.5%. Moreover, if the number of other violating pedestrians grows, the probability of violation would increase significantly. The increase of one unit in “length of the crosswalk”, would result in a violation reduction of 13.9%. Also, if the pedestrian suffers from physical disabilities, the probability of violation decreases by 78.6%. On the other hand, the growth of one unit in “red light duration” would increase the violations by pedestrians 2.2%. 相似文献

Research provides evidence that ride-sourcing has not only substituted for private transport but also public transport. For further investigation of this substitution effect, this paper explores the travel behaviour of ride-sourcing users and those users' socio-demographic characteristics as well as perception of the usefulness of ride-sourcing based on the users' previous modes of transport before ride-sourcing existed. For these purposes, the study collected data using a questionnaire survey in Bandung City in 2018. We found that substitution from public transport exists for younger travellers, while substitution from private transport is most likely associated with infrequent and higher-income travellers. We also found open spaces, a green environment and high interaction society in the residential environments that have more association with high-income travellers, thus associated with lower use of ride-sourcing for former private transport users. This study found that travellers who resided in areas with similar, high-income characteristics tend to have a positive appreciation of ride-sourcing. It appears that the increasing perceived usefulness does not straightforwardly increase the frequency of usage. Therefore, travellers who lived in a more high-end and active social environment might appreciate the role of ride-sourcing services in some of their trips that complement another daily trip. 相似文献

The development of mobile phone applications that provide speed limit advice and warnings offers opportunities for use of the technology in the improvement of driver safety. This paper looks at the effect of an advisory Intelligent Speed Assistance (ISA) application on driver speeding behaviour. Twenty participants (all males within the age range of 35–60 years) completed a within-group experimental design. Participants drove in real traffic on a 46 km test route which incorporated three-speed limits zones (50 km/h, 60 km/h, and 80 km/h speed limits) and aggregated into 10 different segments. Compared with baseline levels, possible impacts of ISA system functionalities on driver behaviour were studied through appropriate metrics including cumulative speed distribution, mean speed, speed deviation, 85th percentile speed, percentage distanced travelled above the speed limit, and safety benefit estimation. Results indicated the use of the ISA application led to significant improvement in speed limit compliance particularly in the 60 km/h and 80 km/h zones where speeding was eliminated. There were no observed negative effects on driver speeding behaviour from the use of the system. In general, the findings suggest the use of the ISA system, resulted in the adoption of vehicle speeds that are likely to improve road safety. 相似文献

对高压共轨柴油机稳态与瞬态工况下的微粒排放粒度分布进行了实验研究。结果表明,高压共轨柴油机排气微粒粒径大部分处于250nm以内,超细微粒占绝大多数。稳态工况下,随负荷增加微粒数量浓度分布曲线峰值逐渐向大粒径方向移动,大负荷工况下峰值开始进入积聚态区域。在瞬态工况下,微粒粒度分布曲线呈单峰形态,平均数量浓度分布峰值位于核态区域,峰值区间为15~25nm。在同一负荷(当量比0.5)下,稳态工况的核态微粒的数量、表面积和体积浓度均较稳态工况大幅度上升;随着瞬变率的增大,核态微粒数量浓度增加而积聚态微粒数量浓度下降。 相似文献

The first field experiment with intelligent speed adaptation (ISA) in Malaysia was held in December 2010 in the State of Penang. Eleven private cars were instrumented with an advisory system. The system used in the present study included a vocal warning message and a visual text message that is activated when the driver attempts to exceed the speed limit. When the driver decreases the speed, the warning stops; otherwise it is continuously repeated. The test drivers drove the vehicles for three months with the installed system, and the speed was continuously logged in all vehicles. The warning was however only activated in the second month of the three month period. The present study aimed to evaluate the effects of an advisory ISA on driving speed, traffic safety, and drivers' attitude, behavior, and acceptance of the system. To examine these effects, both the survey and the logged speed data were analyzed and explored. The results show a significant reduction in the mean, maximum and 85th percentile speed due to the use of the system. However, there was no long-lasting effect on the speed when the system was deactivated. In the post-trial survey, drivers declared that the system helped them well in following the speed limits and that it assisted them in driving more comfortably. Furthermore, the warning method was more accepted compared to a supportive system, such as active accelerator pedal (AAP). After the trial, most drivers were willing to keep an ISA system. 相似文献
