Abstract

The distance between a bus stop and intersection not only concerns the quality and efficiency of transportation, but also has a direct impact on urban environment. This paper combines microscopic traffic simulation model (VISSIM) and motor vehicle emission simulator (MOVES) to establish a platform which can output the traffic indexes as well as the environmental indexes. The grey relational analysis (GRA) method is then employed to incorporate emissions reduction in the site evaluation of urban bus stop near intersections. In this paper, the optimal distance between a bus stop and an intersection is calculated to be 120 meters, where both the traffic efficiency and vehicle emission rate were significantly improved. To sum up, this study provides a better guidance for the site selection of the bus stop near an intersection.
