Abstract

The paper presents the objectives, the approach, the advantages, and some application results of the recent extensions of the traffic signal control strategy TUC (Traffic-responsive Urban Control). Based on well-known methods of the Automatic Control Theory, TUC allows for the traffic -responsive coordinated signal control of largescale urban networks that is particularly efficient also under saturated traffic conditions. The first version of the TUC strategy was controlling only the green splits. After the initial development and the first field implementations and evaluations, TUC was expanded so as to perform real-time cycle and offset control, and to allow for public transport priority. Simulation investigations of the extended TUC application in parts of the urban networks of Tel Aviv and Jerusalem, Israel, by use of the AIMSUN microscopic simulator demonstrate the high efficiency of the new signal control strategy.
