摘要

交通號誌控制系統設置之目的，旨在以時間交互更迭之方式，將路權有效地分配給交叉路口各臨近路段，以提供一個具有安全、效率及順暢的交通環境，然以往相關研究大多著重於時制產製之最佳化，因此時制設計之結果亦極有可能因車道配置不當或時相設計不良，導致不良特制的產生，故綜合考量車道配置、時相設計與時制產製交互影響的關係，實有必要將三者加以整合。有鑑於此，本研究乃以交叉路口進入道路之寬度、禁止左轉、轉向比、等候線長度是主要幹道之相交道路車道數等五項準則，做為車道配置之基本準則，並以車道數、交通流量、視距、安全、速率等五項準則，作為左轉時相設計之標準，透過相關準則之整合評析，提出適用的績效評估方法，確立各項判斷準則標準與分析步驟，最後則建立完安之車道配置與時相設計整合流程，以供交通工程師應用之參考。

The main objective of traffic signal control systems is to assign the right-of-way to each approach of one intersection by timing plan for providing a safety, efficiency and fluency traffic environment. However, since the past related studies usually only emphasize on the optimization of signal timing plans, the design results are not good enough due to the unsuitable lane allocations or signal phasing designs. Therefore, it is necessary to integrate the lane allocation, signal phasing and timing plan designs to ensure the real optimization of traffic control at signalized intersections. This research analyzes five criteria for both lane allocations and signal phasing designs respectively. There are approach width, left-turn prohibited, left-turn or right-turn ratio, queuing length and lanes of crossing way for lane allocations, and number of lanes, traffic volume, sight distance, safety and speed for signal phasing design. The two categories of criteria are used simultaneously to develop an integrated model. By utilizing the integrated model, traffic engineers can design and evaluate traffic control strategies from more comprehensive points of view.
