Abstract:

Mixed traffic condition prevail in most of the developing countries including India, with wide variation in the static and the dynamic characteristics of different types of traffic. The only way of accounting for this nonuniformity 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 is not constant but varies with traffic and roadway condition around. A number of factors have been identifies affecting PCU values. The current study aims at developing a fuzzy based model for the estimation of PCU values for Light Commercial Vehicle (LCV). 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.
