輕軌行人徒步區路權設置準則之研究-以信義輕軌為例

Abstract

本研究從輕軌規劃者立場，探討「輕軌行人徒步區（LRT/Pedestrian Mall）」之路權型式未來在國內輕軌系統中採用時所可能產生的本土化課題，訂定國內輕軌行人徒步區路權設置準則。設置準則的基本架構，從設置地點基本資料收集開始，依序為「都市空間型態分析」、「道路幾何條件評估」、「交通條件評估」和「交通安全改善方式」等項目。透過信義輕軌之實例應用，經過松壽路與信義路間之松智路輕軌路段深具發展輕軌行人徒步區之潛力。其都市空間型態分析結果適合；道路幾何條件上則採用本研究所定義的標準型輕軌行人徒步區；交通條件上，一般交通條件評估結果皆適合，交通衝擊模擬分析結果顯示，採用輕軌行人徒步區路權後輕軌和路網績效都會降低，但當模擬路網的總旅次降低30%以上，整體路網的營運績效將獲得明顯的改善。交通安全改善方式，針對輕軌行人徒步區內的衝突類型提出安全設施措施的改善建議。最後，研究結果建議信義輕軌可採用輕軌行人徒步區路權。

This study is from the LRT system planner angle to confer what kinds of local challenges will be taken placed if the R/W of “LRT/Pedestrian Mall” was introduced into the domestic LRT system in the future, and to set up the application guidelines of LRT/Pedestrian Mall. The basic structure of application guidelines is starting with the “data collection”, the ”analysis of urban space type”, “evaluation of road geometry condition ”, “evaluation of traffic condition”, and the “improvement ways of traffic safety”. In the case study of XinYi LRT system, the section of LRT line passed through the SongZi Rd. is the potential place. The analysis result of its urban space type is suitable, and the evaluation of road geometry condition is fitted to use the standard LRT/Pedestrian Mall. In the traffic condition, the evaluation result of general traffic condition is suitable, and the result of traffic impact simulation analysis shows that the performance of LRT and network will decrease after using the LRT/Pedestrian Mall. But when the total trips on the simulation network descend to 30% or more, the performance will get obvious improved. The improvement of traffic safety is to suggest improvement facilities and measurements according local conflicts types occurred in the LRT/Pedestrian Mall. Finally, the research result shows that it is feasible to introduce the LRT/Pedestrian Mall into the XinYi LRT system.
