自行车交通是一种健康、绿色、环保的交通出行方式,合理地规划自行车出行路线对于满足骑行者多元化出行需求、构建安全规范的城市交通出行环境具有重要的意义.在对真实骑行者路径选择行为深入分析的基础上,提出了基于Open Street Map的城市自行车网络的构建方法及基于其上的多判据自行车路径优化的数学模型,并给出了求解该模型的一种基于聚类的最优多判据路径规划方法.实验仿真结果表明,该模型及方法能够生成满足骑行者真实需求的多判据路线方案. 相似文献

为探究公交站台区域进出站台行人与电动自行车发生冲突时,双方的通行策略选择机制,建立行人与电动自行车通行时间延误模型,分析2类出行者选择是否通行或穿越策略的时间收益,利用复制动态方程刻画2类出行者通行策略的博弈学习行为,建立该区域2类出行者之间的冲突演化博弈模型,结合稳定性分析可以得到该区域2类出行者发生冲突时的稳定通行选择策略。利用桂林市6个公交站台区域的实测数据对演化博弈模型进行实证分析,结果表明:选择“通行”策略的行人群体比例越大,其过街安全感越高;发生冲突时,电动自行车做出决策的时间较行人更短,且2类出行者分别做出“通行”或“穿越”的决策时间短于做出“等待”或“减速”的决策时间,电动自行车平均用时减少约23%,行人平均用时减少约24%。

ABSTRACT Monitoring bicycle trips is no longer limited to traditional sources, such as travel surveys and counts. Strava, a popular fitness tracker, continuously collects human movement trajectories, and its commercial data service, Strava Metro, has enriched bicycle research opportunities over the last five years. Accrued knowledge from colleagues who have already utilised Strava Metro data can be valuable for those seeking expanded monitoring options. To convey such knowledge, this paper synthesises a data overview, extensive literature review on how the data have been applied to deal with drivers’ bicycle-related issues, and implications for future work. The review results indicate that Strava Metro data have the potential—although finite—to be used to identify various travel patterns, estimate travel demand, analyse route choice, control for exposure in crash models, and assess air pollution exposure. However, several challenges, such as the under-representativeness of the general population, bias towards and away from certain groups, and lack of demographic and trip details at the individual level, prevent researchers from depending entirely on the new data source. Cross-use with other sources and validation of reliability with official data could enhance the potentiality. 相似文献

This study investigates the impacts of physical environments on bicyclists’ perceptions of comfort on separated and on-street bicycle facilities. Based on a field investigation conducted in Nanjing, China, we find that physical environmental factors significantly influencing bicyclists’ perception of comfort on the two types of facility. Cyclists’ comfort is mainly influenced by the road geometry and surrounding conditions on physically separated paths while they pay attention to the effective riding space and traffic situations on on-street bicycle lanes. 相似文献

In this paper, a new cellular automata model is proposed to simulate the car and bicycle heterogeneous traffic on urban road. To capture the complex interactions between these two types of vehicles, a novel occupancy rule is adopted in the proposed model to consider the variable lateral distances of mixed vehicular traffic. Based on massive simulations, microscopic fundamental diagrams under different bicycle densities are devised. With these, the bicycle's spilling behavior is then investigated and discussed. In order to reflect the interference of a bicycle on a car, the interference transformation from friction state to block state is modeled explicitly. Finally, different simulation results under different occupancy rules indicate that the constant and fixed occupancy rule adopted in the previous studies might lead to overestimation of car flux in the heterogeneous traffic flows with different bicycle densities.
