成本和网络拓扑对城市机动性的影响:美国两个城市公共自行车使用情况的研究

The Impact of Cost and Network Topology on Urban Mobility: A Study of Public Bicycle Usage in 2 U.S. Cities

Raja Jurdak

摘要:

了解城市流动性的驱动因素对于流行病学、城市规划和通信网络至关重要。到目前为止,人类运动的研究是通过观察人们在给定空间和时间内的位置来进行的,尽管最新的模型只隐含了运动的预期成本和回报。本文探讨了明确的影响,成本和网络拓扑结构的流动性动态,使用数据从2个城市范围内的公共自行车共享系统在美国。用户移动性的特点是通过分布的行程持续时间,而网络拓扑结构的特点是通过成对的车站之间的距离和流行的车站和路线。尽管两个城市之间的车站密度和物理布局存在显着差异,但行程持续时间遵循非常相似的分布,这些分布在定价点边界附近表现出成本敏感的趋势,特别是对于系统的长期用户。根据研究结果,提供了动态定价和激励计划的建议,以积极影响流动模式,并指导改善公共自行车系统的规划和管理,以增加吸收。

英文摘要:

Understanding the drivers of urban mobility is vital for epidemiology, urban planning, and communication networks. Human movements have so far been studied by observing people's positions in a given space and time, though most recent models only implicitly account for expected costs and returns for movements. This paper explores the explicit impact of cost and network topology on mobility dynamics, using data from 2 city-wide public bicycle share systems in the USA. User mobility is characterized through the distribution of trip durations, while network topology is characterized through the pairwise distances between stations and the popularity of stations and routes. Despite significant differences in station density and physical layout between the 2 cities, trip durations follow remarkably similar distributions that exhibit cost sensitive trends around pricing point boundaries, particularly with long-term users of the system. Based on the results, recommendations for dynamic pricing and incentive schemes are provided to positively influence mobility patterns and guide improved planning and management of public bicycle systems to increase uptake.
