公車的最佳站址

Optimal Locations of Bus Stops

大眾運輸規劃過程中，決定車站位置是項重要的工作，然而在過去文獻中，大多數以理論推導出最佳站距或設置站址的原則，這些原則無法落實到確切的車站位置。本研究以啟發式解法，求出最佳的公車站址，並且與其他設置站址的方式比較，發現此方法確實可以節省旅客總成本。同時，本研究並求出最佳車站數及其站址。

The location of stations along a transit line is an important decisionfor planning urban transit system. A mumber of models and algorithms have beenproposed for estimating station spacing. However, most of them failed to giveadequate consideration to the exact station locations. This study considers thecase of locating transit stations along a bus line when number of station andtransit demand are known. We presented a heuristic model that can be used tofind the optimal locations on a bus line. The comparisons were made among sixalternative strategies for locating stations and the model developed in thisstudy. The results showed that the optimal model could lead to lower totalpassenger costs. We also find the optimum number of stops and locations.
