Component

Recently, many Chinese cities have started planning for a transit metropolis. Buses are major components of urban public transportation and the safety of passengers and other road users should be taken into account. The purpose of locating a bus bay is to mitigate the impact of bus stops on traffic flow, and this paper attempts to study the influence of a bus bay on neighboring vehicles in China. Combining the traffic conflict technique and the ordered probit model, the paper records the whole operation of the bus station and explores the factors affecting traffic flow and serious conflicts. The results show that: 1) violations by buses or non-motor vehicles, as well as bus-leaving conditions, have significant impacts on traffic flow; 2) the distribution of conflict severity varies with the phases (entering, stopping, leaving) and positions, and the data show that serious conflicts mainly generated from vehicles’ lane changing when bus leaving the station. The above information indicated that the operation of bus bay probably increases its interference to normal traffic flow during leaving phase. Based on the current public transportation specifications in China and above safety analysis, this paper provides reasonable suggestions for future construction and regulation of bus stations.

This paper was sponsored by TRB committee AP050 Standing Committee on Bus Transit Systems.
