Bus Speed Guidance Strategy within Vehicle Infrastructure Integration Environment

摘要

Aiming at the problems such as unpunctuality and long delays at intersections for public transportation, this paper introduces the dynamic speed guidance theory into the field of intelligent bus control. The paper puts forward two kinds of bus speed guidance strategies within the Vehicle Infrastructure Integration (Ⅶ) environment, which is based on a different signal state at the moment that the bus arrives at the downstream intersection. By applying VISSIM secondary development, we test the speed guidance strategies and evaluate the bus operation with evaluation indexes compared with the situation without speed guidance. The results show that the two kinds of speed guidance strategies are both effective and are able to greatly reduce the bus stopping rate, as well as decrease delay times and fuel consumption.
