Theoretical investigation of emission and delay based intersection controlling and synchronising in Budapest

Abstract

Road transport is one of the main land transport modes providing flexible door to door services. New type of control of road traffic flows in urban intersections is modelled in this article. Furthermore the synchronising possibilities of intersections are investigated as well. Cost of CO₂, CO, CH, NO_x, PM and value of travel time had been used by the authors in order to estimate the cost of road users as a basis of control. The article presents advice for optimal control and gives simulation results based on the emission and delay based costing. Traffic flow parameters, such as traffic flow concentration and traffic flow speed are presented based on real traffic data of investigated intersections. In this article not only single intersections were investigated, but a chain of intersections in order to analyse the recovery potential of synchronization reserves.
