Abstract

The integration of shared mobility services, such as bike-sharing and ride-hailing services, with metro systems enhances the effectiveness and convenience of urban mobility. Various transportation modes significantly impact the accessibility and equity of commercial travel for the purpose of shopping, entertainment, tourism, and catering, due to the diversity of options, destinations, and origins. This study, based on the primary urban regions of Chengdu in 2023, employs the Gaussian two-step floating catchment area model, Gini Index, and Lorenz curve to examine the effects of shared mobility on the accessibility pattern and spatial equity of commercial services. It shows that the bike-sharing-metro travel mode enhances overall commercial accessibility, whereas the ride-hailing-metro travel mode has a substantial impact on accessibility distribution. Additionally, the commercial accessibility distribution pertains to the arrangement of commercial establishments in short-distance travel, whereas it exhibits a central hub and peripheral locations for long-distance travel. While the equity of commercial services improves effectively, metro transportation remains situated at the core of the transportation mode. The creation of the metro transit-oriented development should thoroughly assess the impact of shared mobility on the station area and prioritize the equilibrium between urban commercial and residential sectors.

共享交通如何影响以地铁为基础的城市商业出行的可达性和公平性？

共享出行服务，如共享单车和打车服务，与地铁系统的整合提高了城市交通的有效性和便利性。由于选择、目的地和出发地的多样性，各种交通方式极大地影响了以购物、娱乐、旅游和餐饮为目的的商业出行的可达性和公平性。本研究以 2023 年成都市主城区为研究对象，采用高斯两步浮动集水区模型、基尼系数和洛伦兹曲线，考察共享交通对商业服务可达性模式和空间公平性的影响。结果表明，共享单车-地铁出行模式提高了整体商业可达性，而骑行-打车-地铁出行模式则对可达性分布产生了重大影响。此外，商业可达性分布与短途出行中的商业机构布局有关，而在长途出行中则表现为中心枢纽和外围位置。在商业服务的公平性得到有效改善的同时，地铁交通仍然是交通模式的核心。以地铁为导向的开发项目应全面评估共享交通对车站区域的影响，优先考虑城市商业和居住区之间的平衡。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
