Abstract

This study is about the critical factors affecting the level of service at traffic light junction in Sarawak, Malaysia. Two junctions are selected from two divisions in Sarawak state which are Samarahan Expressway Traffic Light Junction, Kota Samarahan and Jalan Stutong Traffic Light Junction in Kuching city. The factors affecting the level of service are analysed under geometric condition, traffic condition and control condition for each of these intersections are analysed. In order to know which of these factors is the main contributor to Level of service of the two selected intersection, SIDRA Intersection software is used to analyse the data which are manually obtained through traffic volume study carried out at the two traffic light junction during the morning peak period. The method of analysis uses two or three parameters from different conditions. Whereas, by referring to the HCM, these variable parameter values are determined and then input into SIDRA Intersection to get the output, which was; average control delay, existing level of service, and capacity of junction. Fixed values to be input into SIDRA Intersection are obtained from the traffic volume study. The input influences the value for the average control delay which assists in determining the Level of service of the intersection. These output values are highly influenced by the parameters values of every factor that were input. From observations, all factors analysed under three conditions to determine level of service of the two traffic light junction were contributing equally and correlates with each other and there was not one that exceeds the other factor. Nevertheless from the analysis, the critical factor affecting the level of service is arrival type and lane width.
