巷道人行交通安全評估分級之建立

LEVEL OF SAFETY CLASSIFICATION OF PEDESTRIAN TRAFFIC ON LOCAL STREET

地區巷道的人行交通安全情形一般皆不理想，主要是因為缺乏人行空間，導致人車衝突嚴重。有許多人車共存的交通寧靜措施可用來改善巷道人行安全品質，但是如何選擇及評估其績效，則尚待研究。因此，本研究即在延續過去的研究所建立的巷道人車交通衝突風險模式，將之利用模糊理論加以分級建立巷道交通安全分級方法。並以實際之案例進行應用分析。結果顯示，此一分級評估方法確實可用來預先分析一個巷道的安全水準及改善措施。

Traffic safety of pedestrian on local street is generally poor due to the lack of space for pedestrian, and the latter causes serious traffic conflict condition between vehicle and pedestrian. There are various traffic calming countermeasures to improve the poor traffic condition of local street. It's necessary to develop a method to evaluate the performance of such traffic calming countermeasures. Basing on the Risk Index developed in the preceeding research, the level of safety (LOS) is defined and classified into five levels using fuzzy classification method. For practical application, in this paper several locations were selected to assess their level of safety, and, furthermore, the safety performance of proposed improvement countermeasures. The research results indicated that the method is workable.
