Abstract

An urban traffic control system (UTCS) is a system that controls the vehicle traffic in urban networks through the operation of traffic lights. This control is implemented by a very complex system consisting of computer systems, telecommunications subsystem, detectors etc. One of the most serious problems is how to evaluate the effects of such a system. Up to now the evaluation of UTCSs has been done by applying the so-called single-criterion approach. This paper presents a new approach to the problem based on a multicriteria ranking method. The problem of choosing and grouping the criteria for evaluation is considered first. All criteria are grouped into five groups. The problem of determining weighting factors, for each group and each criterion within a group, is solved. Then, by using compromise programming, the ranks of traffic states before and after UTCS installation are given. A special approach to determining ideal and veto values is described. At the end, the problem of strategies and their influence on the evaluation results is treated. A special algorithm for determining the best strategy is given. The whole procedure is illustrated by the example of the Belgrade UTCS evaluation.
