A review on chicane design based on calming theory

Abstract

Chicane has been widely recognized and applied as a traffic calming measure to decrease vehicle speed, reduce traffic accidents, and improve arterial traffic. The design of chicane is influenced by various factors. To analyze the influencing factors of chicane design systematically, investigate chicane design on the basis of traffic calming theory, and summarize the development trend of chicane, this study reviewed the explore progress in the structure setting form of chicane, geometric design parameters, and influencing factors of traffic safety. Moreover, the uncertainties in the natural environment and operation process were analyzed, and the future development direction of chicane in urban road calming technology was discussed. Results demonstrate that chicane is an extremely effective traffic facility to ensure traffic safety. The geometric design of chicane mainly focuses on free view width a and stagger length l. However, the existing design of chicane is not uniform, and driving behavior is not standard.
