Abstract: Conventional models estimating vehicle delay are all established only based on technical factors with little considering non-technical factors, which can not be depicted in engineering models directly. Even for technological factors, conventional models consider them only by introducing some adjusting factors, which varies from place to place and are difficult to be calibrated. In this papaer, a fuzzy table look-up system for estimating time delay is built up based on rule base containing technical and non-technical information from actual surveyed data sets. By changing timing parmeters (cycle, green time, and etc.), optimal timing strategy with minimum total delay can be easily obtained. An example is given to illustrate the proposed approach. This approach can be used not only in isolated intersection timing but also in arterial signal timing, network signal timing, traffic guidance system and etc. Wide applications can be expected in the field of traffic control engineering.
