• Local road utilization
• Detour ratio
• Taxi GPS data

Local roads play an important role in increasing city mobility, and bringing convenience for citizens. In this paper, the utilization of Beijing local roads is analyzed using taxi GPS data for the first time. We evaluate the utilization of Beijing local roads quantitatively from different perspectives, with the aim to answer two questions: 1. Is there a problem of low utilization rate of local roads in Beijing? 2. If yes, which parts of Beijing are worse? To quantify utilization rate of local roads we propose detour ratio R index. With this index, we perform analysis from different perspectives, including comparison between Beijing and New York City, and efforts to figure out areas with low local road utilization rate. The results show that Beijing does have the problem of low utilization rate of local roads, and areas with low local road utilization rate are concentrated in Zhichunlu (), Muxidi (), Shuangjing (), and Liuliqiao () regions. The paper concludes with some policy suggestions regarding how to improve the utilization of local roads. This study offers significant insight that can help understand the urban road construction better, improve traffic condition and human life quality.
