Simulation of the Pedestrians' Influence to the Capacity of Motorised Vehicles in a Roundabout

Abstract

A new approach is suggested for dimensioning roundabouts with mathematical modeling of traffic flows using the discreet simulation method, and considering the statistically evaluated entry data for vehicles’ and pedestrians’ traffic flows. The simulation results are useful when determining the capacity of the roundabouts, which will function in different circumstances. The presented model derives from the expected time void in the vehicles’ traffic flow, used by the pedestrians, presuming their advantage when joining into the traffic. The simulation analysis has been verified on a real example of a montage roundabout in Maribor, where measurements of motorized vehicles’ traffic flow, pedestrians’ and cyclists’ traffic flow had taken place.
