CHOSEN PROBLEMS OF DESIGNING VEHICLE ACTUATED ROAD TRAFFIC CONTROL
Journal Title: Scientific Journals of Silesian University of Technology. Series Transport - Year 2013, Vol 2013, Issue 80
Abstract
Problems occurring in practice of designing actuated traffic control are described in the paper. It is based of own experience of the authors. Short description of designing stages is given and of specific problems as well. At the beginning, the issues of selection of traffic stages and their sequence are discussed focusing on impact of this stage for further designing. The case of inappropriate selection of a set of stages and resulting control constraints are described. The complexity of designing process when more traffic stages considered is also discussed. Further, the problems of interstages defining are presented. The most common mistakes and risks resulting from improper interstages defining are described. The labour intensity required for interstages defining at multistage control systems is signalized. The next part of the paper focuses on problems of determination of control time conditions. Different types of time conditions, methods of their determination and impact on control flexibility are presented. As resumé, the trends of current research in the field of traffic control and methods used to solve the problems described are presented. This paper is based on practical cases of real crossroads traffic control designs.
