How to improve signal efficiency in urban traffic networks is a critical issue to the success of Advanced Traffic Management Systems (ATMS). Based on advanced traffic surveillance and management systems, link flow data and path flow data might be available to traffic management centers to design efficient signal control strategies. According to different data, link-based and path-based algorithms are developed for arterial selection, and the signal optimization algorithm is based on PASSER models. This research aims at designing appropriate arterials for signal coordination, and associate signal strategies for these arterials. The algorithms are implemented through C++, an object-oriented language. The traffic simulation-assignment model, DynaTAIWAN is applied to evaluate signal coordination model and associate signal strategies in a experiment network and a true network. Numerical experiments are conducted based on DynaTAIWAN to illustrate the algorithm developed in this research.
