The problem of performance evaluation at signalized intersections with various traffic control strategies

Abstract

Different traffic control strategies affect the performance of a signalized intersection through variable signal timing in response to traffic demand. The capacity of signalized intersections can be determined with the combination of signal timing and saturation flow. The performance on signalized intersections also depends on signal timing, e.g., stopped delay can be estimated with the combination of green time, cycle length and the other parameters. A method or a parameter for performance evaluation on signalized intersections should be able to evaluate the contribution of various traffic control strategies on intersection performance. Therefore, the problem of evaluation by traffic dependent control strategy was addressed in this paper. As example, this paper presents the result by traffic actuated control. Further research is to be expected in the future with respect to the conclusion of this paper.
