路段交通管制意義之研究

Abstract

道路交通管制係規範用路人使用道路之有關規定，亦是影響道路使用績 效(Performance)之重要因素，本研究以台北市為例探討路段交通管制與 績效間之關連，首先收集各種交通管制方式實施條件之理論及研究成果， 形成各種管制方式之相對性假設，而後調查各種交通管制方式道路之實質 條件及績效狀況資料，並進行其交通行為之比較研究與統計檢定，用以確 定其意義與相對地位。研究結果顯示不同管制會導致不同之車道容量( Lane Capacity)，而道路交通管制之意義依性質大致可分為三群：第一群 包括無管制、行車分向管制及巷道單行管制，其管制之意義在於道路使用 之可及性(Accessibility)，容許各種使用共存於道路空間，第二群包括 分向限制、中央分隔、快慢分隔及幹道單行等管制，此些管制去除或分隔 各種使用，唯仍保留轉向功能，第三群單指出入管制道路，其更進一步把 轉向之功能亦加以限制，完全強調其移動性(Mobility)。另外各種管制之 績效範圍存在模糊(Fuzzy)性，為表達此一特性本研究以百分之九十五信 賴區間顯示各管制方式之績效範圍，其間或有重疊、或有分野，唯此模糊 關係仍待更進一步之探討及研究。 Road Traffic Regulations (RTR) are a set of guidance to road users for using roads. They are also important factors influencing the performance of road using. This study is aimed at analyzing the relationship of physical conditions RTR and performances. At first, theories and research reports are reviewed and the hypothesis in the relationship mentioned above are formed road section. Secondly, through data collection hypothesis testing, the relativity of various RTR are revealed. Important findings in the analysis including follows:1. Lane capacities are very related to RTRs.2. In terms of significance, RTR can be classified into three categories: the first group gives the greatest accessibility for the road. The second group separates some of the uses of road, but still reserved turning function. The last group gives the greatest mobility for the road.3. Fuzzy characteristics are formed in the relationship between RTRs and performances. 95% confidence interval of their performances are used to delineate the boundary of the fuzzy sets. But the membership function need to study further.
