Thus, exploring the spatial configuration of the urban bus service system promotes an understanding of the quality of bus services. Such an understanding is of great importance to urban transport planning and policy making. In this study, we investigated the spatial characteristics of an urban bus service system by using the complex network approach. First, a three-step workflow was developed to collect a bus operating dataset from a public website. Then, we utilized the P-space method to represent the bus service network by connecting all bus stop pairs along each bus line. With the constructed bus network, a set of network analysis indicators were calculated to quantify the role of nodes in the network. A case study of Shenzhen, China was implemented to understand the statistical properties and spatial characteristics of the urban bus network configuration. The empirical findings can provide insights into the statistical laws and distinct convenient areas in a bus service network, and consequently aid in optimizing the allocation of bus stops and routes.<\/jats:p>","DOI":"10.3390\/ijgi8110486","type":"journal-article","created":{"date-parts":[[2019,10,31]],"date-time":"2019-10-31T05:18:26Z","timestamp":1572499106000},"page":"486","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Exploring the Characteristics of an Intra-Urban Bus Service Network: A Case Study of Shenzhen, China"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2507-4757","authenticated-orcid":false,"given":"Xiping","family":"Yang","sequence":"first","affiliation":[{"name":"School of Geography and Tourism, Shaanxi Normal University, Xi\u2019an 710119, China"},{"name":"Geomatics Technology and Application key Laboratory of Qinghai Province, Xining 810001, China"},{"name":"Shaanxi Key Laboratory of Tourism Informatics, Xi\u2019an 710119, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shiwei","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Architecture and Urban Planning, Huazhong University of Science and Technology, Wuhan 430074, China"},{"name":"Key Laboratory of Urban Land Resources Monitoring and Simulation, Ministry of Land and Resources of China, Shenzhen 518034, China"},{"name":"Beijing Key Laboratory of Urban Spatial Information Engineering, Beijing 100038, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weifeng","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Geology Engineering and Geomantics, Chang\u2019an University, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiyuan","family":"Zhao","sequence":"additional","affiliation":[{"name":"Academy of Digital China (Fujian) and Fujian Collaborative Innovation Center for Big Data Applications in Governments, Fuzhou University, Fuzhou 350002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,29]]},"reference":[{"key":"ref_1","first-page":"21","article-title":"Performance improvement of urban bus system: Issues and solution","volume":"2","author":"Pittschieler","year":"2010","journal-title":"Int.
