Abstract
輕軌列車長度受限於路線最小街廓長度與最小轉彎半徑，不同長度將影響其營運容量、路口橫向交通之衝擊等等。世界各城市營運之輕軌列車長度不盡相同，而列車長度之決定多以工程師經驗採取「因地制宜」的作法，缺乏一套明確量化的決定機制。因此本研究的以VISSIM為模擬平台，以不同列車長度應用於不同設站位置、同向交通量、橫向交通量、輕軌班次、街廓長度之組合情境，分析輕軌列車、同向車流、橫向車流之延滯。並以「輕軌平均車延滯」與「通過路口總平均人延滯」作為績效評估指標，將各種模擬情境之結果以多元迴歸模式，建立不同列車長度下，延滯與各項變數之迴歸式，決定各情境下較佳之列車長度，作一分析比較，以作為日後各縣市欲使用輕軌系統時決定列車長度之參考。
The length of the Light Rail Vehicle is limited with the minimum block length and the minimum turning radius of the course. Different lengths would affect its working capacity, traffic and etc. Different cities have different lengths of the Light Rail Vehicle. Because we lack a system to measure the length of the Light Rail Vehicle, we usually take experienced engineers' advices to take actions that suit the local circumstances. Therefore, we use VISSIM to be our simulation platform for this study. We put different lengths of the vehicle into a situation of different stopping spot ,traffic flow , and the vehicle services. As the result, we analysis the delays of Light Rail Vehicle,. We use “average vehicle delay” and “average person delay” to be performance evaluation indicators, and we also use different simulation results to model the regression formula of delays and variances in different lengths with multiple regression. Finally, we compare the different results that we got and find the better length for each circumstance. We hope it could be a reference for those who want to build the Light Rapid Transportation.
