Highway Capacity Analysis Based on JKR Traffic Census

When designed road approach its demand, we started to experience lower speed and congestion. In Malaysia, the capacity of road was designed based on Jabatan Kerja Raya (JKR) design standard. JKR traffic census is the survey done twice a year to check the traffic volume. The data collection of current traffic will be combined with other known data such as population, employment, trip rates, zones , travel cost , etc. to enable us to forecast the future demand. The current data also helpful in determining whether the current road was sufficient or further development was needed in the future. The scope of this research is at Perak where the government plans to make Perak a high-income state with a viable economy. With the future development plan, the existing roads within Perak will be affected. The new transportation plans are needed to meet those demands. New analysis on the highway capacity and design should be done, to check the current level of service while compare it with designed capacity. The capacity analysis will based on the Highway Capacity Manual (HCM2000) to determine the performance of current facilities and compared with expected annual traffic growth.
