Road pricing and spatial distribution of traffic flow in radial-arc network

Abstract This paper discusses the effect of road pricing on spatial distribution traffic flow. The flow density is derived for a circular city with radial-arc network. describes amount as function position and allows us to identify location potential congestion areas. analytical expression demonstrates how size toll area level affect As increases, decrease in inside becomes smaller. increase at boundary greater. travel cost also examined. These findings can be used determine required achieve certain congestion.
