2011 - India - Passenger Car Units for Trucks


2011 - India - Passenger Car Units for Trucks

In developing countries including India, mixed traffic condition prevails on roads and highways. There is a wide variation in the static and the dynamic characteristics of different types of traffic. The only way of accounting for this non-uniformity for any traffic analysis in traffic stream is to convert all vehicles into a common unit and the most accepted unit for this purpose is passenger car unit (PCU). PCU value for a vehicle varies with traffic and roadway condition around. A number of factors have been identified affecting PCU values. The current study aims at developing a fuzzy based model for the estimation of PCU value for trucks. Fuzzy based model is of importance because of a number of independent affecting factors. Results of developed fuzzy MATLAB based model are compared with the quoted results and are found with high degree of correlation.
