Improved Model of Pedestrian and Turning Transport Flow Interaction for Estimation of Economic Traffic Expenses

Abstract

Selection of the scheme concerning organization of movement of turning transport flows at crossings with traffic light regulation is presently determined by simplified criteria of pedestrian safety without taking into account other traffic expenses. So the existing schemes of regulation often lead to rather high economic and ecological expenses.

The paper proposes a model of pedestrian and turn transport flow interaction. This model is modified on the basis of experimental results. In addition to this the paper contains system of dependencies that permits to determine with high accuracy volume of economic and ecological expenses in order to select optimum scheme of the organization of traffic movement at the regulated crossing.
