Analysis of traffic features in vehicle access roads to large public buildings in the urban area

Abstract

Paper presented at the 26th Annual Southern African Transport Conference 9 - 12 July 2007 "The challenges of implementing policy?", CSIR International Convention Centre, Pretoria, South Africa. ABSTRACT: Vehicle access roads to large public buildings in urban areas seem to be the link between the inner city traffic and the outer urban traffic, making them important nodes in the urban road network. An analysis of the traffic features of vehicle access roads would be of assistance in choosing logical traffic management measures for the connecting node between the building traffic and urban traffic. At the beginning of this analysis, the behaviour and attitudes of motorists are analysed, which are the basis of the traffic features. The traffic flow characteristics are then discussed in detail in terms of the following aspects: vehicle queuing model, car-following model and vehicle diversion model. Finally, the effect of pedestrians and cyclists is examined. Because of the stochastic properties of pedestrian and bicycle flow, any disturbance has a great impact on the state of traffic operations. It is therefore necessary to separate the flow of pedestrians and cyclists from the vehicle flow.
