Congestion is a normal occurrence on the urban Malaysian expressway system, usually associated with areas having entrance ramp, exit ramp and weaving section. A good practice for expressway system can be determined by the efficiency of the traffic operation itself. Thus, this research paper provides the assessment of level of service for entrance ramp merging using US HCM 2000; US HCM 2010 and empirical data as the indicator. Study was conducted at KM 12, Grand Sepadu Expressway, Selangor and the data were collected by using TRAX Apollyon Automatic Traffic Counter. An analysis was conducted and the RSME result shows that the plotted data are successfully developed and validated in these studies. © Published under licence by IOP Publishing Ltd.
