Abstract

Urban traffic in Phnom Penh is characterized by the high level of mixed traffic with an extremely high proportion of motorcycles. Rapid growth of motorcycles with their behavior in traffic is the main cause of road congestion and accidents. Recently, there is also a drastic increase in number of light vehicles including car, pick-up, and van causing a more serious problem on traffic capacity and safety. Firstly, this paper investigates the traffic performance of motorcycle-dominated urban street under the impact of light vehicle, whereby particular observation on how motorcycle responds under different proportions of light vehicle is conducted. Data was collected using videotaping technique. Secondly, the present paper examines motorcyclists' perception on traffic safety issue and the extent to which they involve in traffic accident based on motorcycle driver interview survey. Finally, discussion on how to improve capacity and safety is made.
