INCREASE IN EFFECTIVENESS OF DEFINITION OF ELEMENTS OF A CYCLE OF TRAFFIC LIGHT REGULATION.

Abstract

Studying subject in article is new approach of determination of parameters of the movement of vehicles and feature of the modern organization of monitoring of traffic flows on such adjustable traverses. The purpose is development of the new mode allowing to increase level of quality and complex assessment of definition of elements of cycle of traffic light regulation (TLR) in the conditions of change of parameters of the movement TF in intersection zone. Research problems: the analysis of the existing approaches of monitoring of TF at adjustable intersections; development of the new mode allowing to obtain fuller information for control and effective determination of optimum values of time of action of elements of the cycle TLR; development of the mode meeting the requirements of the multiple-purpose adaptive systems allowing to react effectively to changes of traffic conditions of TF on the intersection. The following results are received. Some features of the modern organization of monitoring of TF on local objects are revealed and also their main merits and demerits are analysed. The new mode of definition of elements of the cycle TLR in the conditions of dynamic change of parameters of the movement TF and adaptive response of system to road situation is presented. The option of the simplified structure of the device for realization of the offered mode and effective processing of initial information is given, the feasibility and operability of the algorithms put in mode is shown. Conclusions. Effective determination of parameters of the movement TF in intersection zone on each strip of the movement during traffic light cycle gives the chance to obtain fuller complex of information for control and the subsequent operational management of the movement at the intersection. Ways of expansion of functionality of the offered mode due to simultaneous determination of additional parameters of condition of TF at the intersection and criteria for evaluation of quality of TLR are shown. The flexible technology and complex assessment of the TLR modes allows to carry out in real time as parametrical adaptation (optimization of elements of cycle), and structural adaptation due to reorganization of schemes of steering of the movement.
