Penentuan Hubungan Laju-Aliran Lalu Lintas Jalan Arteri

Presently, there is no published relationship between speed and traffic flow for arterial road in Malaysia. Report onTraffic Study Malaysia indicates the relationships of speed and traffic flows for uninter rupted flow facilities.An arterial road isa road consistingof traffic light junctions within 3 km distanceor less and carrying high through traffic volume.This studyisconductedtowardsproducing therelationships between speedand traffic flow for arterial roadsin Malaysia.The speed-flow relationships was developed using an existing traffic flow model.The specific aim of thisstudy is to determinewhich model is appropriate with respect to Malaysian traffic characteristics. The relationships ofspeed and traffic flow aretwo parameters that are very important for planning and modeling of transportation facilities. In this study, travel speed and traffic flow were collected at several selected sites. The collected data were analyzed basedon Greenshields, Greenberg,Underwood and DrakeModels.The results of the analysis study has shown that Underwood Model is the most suitable model that can be usedto define the relationships betweenspeed and traffic flow based on Malaysian road condition.The data of observed free-flow speed in the field werealso compared with predicted free-flowspeed byeachmodel.
