Analysis of Normal Stopping Behavior of Drivers at Urban Intersections in China by Tian Yuan, Rui Liu, Xuan Zhao, Qiang Yu, Xichan Zhu, Shu Wang

“…The main results indicate the following: (1) compare with free driving, the approach speed in the following state was lower, and following traffic also caused drivers with higher speeds to further increase reaction distance in high-density traffic. (2) Traffic density only affected the approach speed in the free-driving condition. …”
