Abstract

Passenger Car Unit (PCU) can also be termed as passenger Car Equivalent (PCE). PCU is a unit used in Transportation Engineering. To study the rate of traffic flow on any intersection or road we must have studied PCU value of various categories of vehicles. Passenger Car Equivalent of any type of vehicle is the effect of vehicle on traffic variable as compared with a Standard Passenger Car. Transportation plays an important role in the growth of any country. In developing country like India, Road Transportation plays very crucial role in the development. Nature of the traffic on developing countries like India is heterogeneous in nature. As we all know, India has second largest network in the world. Roads are the most common and used mode of transportation. Various categories of vehicles which differ in dimension are available on the roads. So any set of values of PCU is not suitable for that particular location or condition. This means that we cannot simply depend upon the static PCU values provided in the manuals, we need to calculate dynamic values of PCU varying with respect to location or condition. Two Methods are used for determining the PCU values at unsignalized intersections. In first method the PCUs are estimated as per Highway Capacity Manual considered at unsignalized intersections. In HCM the PCU values are calculated using occupancy time method. In second method, the method proposed by Chandra & Kumar for estimation of PCUs is used. It is most popular method used for estimation of PCUs which is used in various countries of the world. Data was collected at unsignalized intersections. There was not obstruction in observation of traffic due to roadside construction, bus stop, market etc. There was no signalized intersection in the range of 3 km. roadway length. Traffic volume was collected in peak hours and in both directions. Speeds of various types of vehicles were also measured. The results obtained from the above methods were compared with the values given in Highway Capacity Manual and it shows there is difference in values of PCU, which is given in HCM. This suggests that we need to take dynamic value of PCU depending upon the characteristics of location and other variable for traffic volume study or analysis. Further study or research can be carried out for estimating the dynamic values of PCUs at Expressways, National Highways etc.
