论文摘要

在世界各地的城市中,共享的按需服务正在迅速扩展。作为一个重要的例子,基于应用程序的骑行源正在成为许多城市运输生态系统中不可或缺的一部分。尽管有核心性,但关于骑行旅行的详细时间和空间数据的公共可用性有限,对新服务如何与传统出行选择互动以及它们如何影响城市的旅行的研究有限。改善数据共享协议正在为该领域的研究开放。这项研究使用最近发布的芝加哥市公共骑行数据来检查新兴的活动模式。详细的时空骑行数据与天气,运输和出租车数据相匹配,以更深入地了解芝加哥移动性系统中的骑车角色。目的是调查乘车骑行的系统差异。 K-Prototypes用于检测用户段,因为它可以接受混合可变数据类型。 K-均值算法的扩展,其输出是将数据分类为几个称为原型的簇。基于与不利天气条件,替代模式,位置和使用时间的竞争以及乘坐趋势的竞争,识别和讨论了六个骑行原型。本文讨论了与交通的可负担性,公平性和竞争有关的确定集群的含义。

Shared mobility-on-demand services are expanding rapidly in cities around the world. As a prominent example, app-based ridesourcing is becoming an integral part of many urban transportation ecosystems. Despite the centrality, limited public availability of detailed temporal and spatial data on ridesourcing trips has limited research on how new services interact with traditional mobility options and how they impact travel in cities. Improving data-sharing agreements are opening unprecedented opportunities for research in this area. This study examines emerging patterns of mobility using recently released City of Chicago public ridesourcing data. The detailed spatio-temporal ridesourcing data are matched with weather, transit, and taxi data to gain a deeper understanding of ridesourcings role in Chicagos mobility system. The goal is to investigate the systematic variations in patronage of ride-hailing. K-prototypes is utilized to detect user segments owing to its ability to accept mixed variable data types. An extension of the K-means algorithm, its output is a classification of the data into several clusters called prototypes. Six ridesourcing prototypes are identified and discussed based on significant differences in relation to adverse weather conditions, competition with alternative modes, location and timing of use, and tendency for ridesplitting. The paper discusses implications of the identified clusters related to affordability, equity and competition with transit.
