Impact of pedestrian flows on traffic delays before roundabouts

The paper examines a roundabout located in a residential district of Lviv city. The area has many attraction points, so traffic and pedestrian flow volumes are large. All approaches to the roundabout have unsignalized pedestrian crosswalks, three of which lack safety islands. Field studies were conducted on peak and off-peak periods, collecting primary indicators of traffic and pedestrian flows. Traffic flow delays were determined on the approaches to the roundabout under existing traffic conditions with the help of the PTV VISSIM software.

Choose of optimal regimes of traffic light control in operating zone of pedestrian crossing

On the given stage of motorization level development and increase of traffic flow intensity, with increasing frequency apply to the implementation of intelligent automated systems of traffic control. The quality of their work depends foremost from study of the primary factors of road users, their behavior, including the factor of a person as movement operator, geometric parameters of communication routes, road conditions as movement environment. Such study is held by methods of field research, documentary research and mathematical modelling.
