在先進交通管理系統 (advanced traffic management systems, ATMS) 與先進駕駛者資訊系統 (advanced traveller information systems, ATIS) 的發展中，動態交通指派針對依時性 (time-dependent) 的起迄資料進行路網內路徑最佳化的指派。目前已被應用在動態交通指派問題的方法，色括最佳控制化理論、變分不等式、數學規劃法，與模擬式的指派程序等四種。本文將針對模擬式的動態交通指派模式作一介紹與探討，在此一模擬式的動態交通指派演算法中，DYNASMART模式，將取代路段績娃的使用，並反應路段流入與流出率的計算控制。此一演算法的最大優點在於反應車流特性與交控策略的影響。本研究以一測試路網與一實際路網作為初期測試之用，以數值實驗來探討此一演算法的合理性，並討論此一演算法未來在資訊化路網中的可能應用。

The need for a method to provide time-dependent estimates of traffic flows and associated peformance measures in networks arises in several problem area ,such as the advanced traveler management systems (ATMS) and advanced traveler information systems (ATIS). Four different approaches, including mathematical formulations, optimal control theory, variational inequalities, and simulation-based approach, have been applied in developing dynamic traffic assignment (DTA). In this study, the concept of Texas approach - micro-simulation-based DTA, is introduced and explored. The core of the procedure is DYNASMART, a simulation­assignment model is used to replace link-performance and exit functions. Numerical experiments on a test network and a real network are conducted to investigate time-dependent flow patterns and real-time dynamics under a wide variety of assumptions on assignment rules.
