Abstract
Research investigating the influence of passenger car equivalents for motorcycle (PceMC) value on 4/2D road has been carried out in order to find the correction value of PceMC and investigate its impact on the road performance in developing countries. This research is carried out on Teuku Umar Street, one of 4/2D road in Bandar Lampung City - Indonesia. Standard calculation used in this research is Indonesian Highway Capacity Manual (IHCM). Primary data used in the analysis is the data derived from field survey of traffic counting, spot speed, and space mean speed. The value of PceMC is determined based on the assumption of the ratio of road space utilization by motor cycle.The correction value of PceMC is calculated using trial and error method in order to find the minimum difference between light vehicle speed value (DVLV) from graph analysis and the one from spot speed survey data. Research indicates that the correction value of PceMC for Teuku Umar Street is 0.323. The value of DVLV on PceMC standard of 0.25 is 3.29km per hour, while the one on corrected PceMC of 0.323 is 0.007km per hour. The average spot speed is found as 38.80km per hour. Research also indicates an over estimation on the road performance of Teuku Umar Street if PceMC standar of 0.25 is used as basic of calculation.
