Choice of Pedestrian Crossing Type at Crossroads Using Simulation

Abstract

In the paper there is carried out an analysis of transport delays in the city of Bryansk at the designed intersection with a circular motion connected with the necessity to allow high-intensity pedestrian flows to pass; the problem is complicated with the stop location close to the crossroads and a high share of route passenger vehicles. A basic purpose of the investigation is a definition of an optimum option for the organization of high-intensity pedestrian motion through a carriageway close to the crossroads with a circular motion. 
 With the aid of the simulation in PTV Vissim environment there is carried out a comparative analysis of a basic option of a road traffic organization (completely controlled crossroads) and three design options of circular motion with different types of pedestrian crossing and its location regarding the crossroads and the stop. 
 The assessment of carrying capacity and transport delays at the crossroads approach has shown that at a constantly high intensity of pedestrian flow motion in the course of a day it should be expedient to use a controlled pedestrian flow through a pedestrian crossing moved from a circular carriageway; this option allows decreasing transport delays for almost five times as compared with an uncontrolled motion and by more than 20% in comparison with the controlled pedestrian flow close to a ring.
