Abstract

Most road networks are designed horizontally on the same plane and this often leads to intersections and conflicts. Vehicular traffic at a road junction and roundabout is examined. Queue theory models are discussed and applied to two road junction types, A T-junction and a roundabout. Expected road traffic build-up and relaxation times are presented. The time that must elapse for the system to return to free-flow state was calculated and results show that it takes longer time for traffic congestion to relax compared to its build up time. Road traffic build-up is higher in the T-junction than the roundabout.
