Analysis of methods of generating input variables for probabilistic models of transport processes.

摘要

Problems occurring in practice of designing actuated traffic control aredescribed in the paper. It is based of own experience of the authors. Short description ofdesigning stages is given and of specific problems as well.At the beginning, the issues of selection of traffic stages and their sequence are discussedfocusing on impact of this stage for further designing. The case of inappropriate selection of aset of stages and resulting control constraints are described. The complexity of designingprocess when more traffic stages considered is also discussed.Further, the problems of interstages defining are presented. The most common mistakesand risks resulting from improper interstages defining are described. The labour intensityrequired for interstages defining at multistage control systems is signalized.The next part of the paper focuses on problems of determination of control timeconditions. Different types of time conditions, methods of their determination and impact oncontrol flexibility are presented.As resumé, the trends of current research in the field of traffic control and methods usedto solve the problems described are presented. This paper is based on practical cases of realcrossroads traffic control designs.
