| Summary: | Presently, there is no published relationship between speed and traffic flow for arterial road in Malaysia. Report
on Traffic Study Malaysia indicates the relationships of speed and traffic flows for uninterrupted flow facilities.
An arterial road is a road consisting of traffic light junctions within 3 km distance or less and carrying high
through traffic volume. This study is conducted towards producing the relationships between speed and traffic
flow for arterial roads in Malaysia. The speed-flow relationships was developed using an existing traffic flow model. The specific aim of this study is to determine which model is appropriate with respect to Malaysian
traffic characteristics. The relationships of speed and traffic flow are two 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 based on Greenshields, Greenberg,
Underwood and Drake Models. The results of the analysis study has shown that Underwood Model is the
most suitable model that can be used to define the relationships between speed and traffic flow based
on Malaysian road condition. The data of observed free-flow speed in the field were also compared with
predicted free-flow speed by each model |
