MODELLING THE TRAFFIC ROLE AND PERFORMANCE OF ROUNDABOUTS. 14TH AUSTRALIAN TRANSPORT RESEARCH FORUM, PERTH 20-22 SEPTEMBER 1989; FORUM PAPERS. VOLUMES 1 AND 2

Roundabouts offer environmental enhancements and act AS Effective speed control devices in road networks. A number of factors affect the performance of roundabouts including the proportion of turning movements, unbalanced (tidal) flows (typical of peak flow patterns), and sight distance. The complexity of the traffic operation of roundabouts means that detailed analytical analysis is impractical, and suggests that simulation modelling may be needed to investigate the detailed performance of roundabouts. This paper reviews the use of roundabouts as part of urban arterial road traffic control and in local area traffic management. Questions about how roundabouts fit to an urban arterial network are still not clearly understood. The results from a preliminary simulation model are described, and future developments and use of the simulation model are outlined (a). For the covering record of the forum, see IRRD no 822808.
