A study on the effects of PCE values on the design of signalised intersections

Signalised intersections are an essential part of a road network, particularly in urban areas where traffic congestion has always been a major problem. In terms of economic values, congestion will indeed cause the loss of man-hours. Hence, to further enhance the national economy, it is imperative to design signalised intersections accurately according to proper design standards. Capacities of signalised intersections are determined based on individual approaches and they are expressed as saturation flows. Saturation flows however, are influenced by the proportion and type of vehicles in the traffic stream. Therefore, passenger car equivalents (pce) are assigned to various categories of vehicle so that saturation flow can be corrected to the common base of passenger car units per hour (pcu/hr). The pce values currently used in Malaysia are based on the Arahan Teknik (Jalan) 13/87 published by the Public Works Department of Malaysia in year 1987 and have not been revised since then. This research will attempt to derive new pce values based on Malaysian road conditions and the effects of these pce values as compared to the values adopted by Arahan Teknik (Jalan) 13/87 in the design of signalised intersections will be discussed.
