Assessing the Optimal Location of Near Side Bus Stop to Enhance Advantages of Bus Signal Priority (BSP)

抄録

In this paper, bus signal priority (BSP) with different near side bus stop position in reference to the average queue during red time of the selected intersection and bus detection after bus departure from stop was modeled. Three alternative positions such as bus stop within normal queue, at the end of normal queue and beyond the distance of normal queue were evaluated for traffic flow ratios of 0.7, 0.9 and 1.1 by simulation method. Two objective functions i.e. decrease in delay for priority movement and increase in delay for non-priority movements were considered. Since there are two objective functions, Pareto-optimal situation arises. The optimal case was selected based on the shortest normalized distance to Pareto optimal sets. Bus stop at the end of normal queue outperforms reducing total person delay in priority direction with least increase in total person delay on non-priority direction.
