EFFECT OF VEHICLE SIZE ON HIGHWAY CAPCITY IN THAILAND

This is a report of the second part of a project to determine the capacity of the uninterrupted-flow highway in Bangkok. The data collection is described. The data used were the average minimum headways adopted by various types of vehicles collected in the form of time headways defined as the time in seconds for the rear bumper of two successive vehicles in the same lane to pass a common reference point. The details are given of the headway classification, and the data analysis. The results are discussed of the determination of capacity, the effect of vehicle size on capacity, and the estimation of passenger car equivalents. It was found that the value of the basic capacity of uninterrupted-flow highways in Thailand, based on the average minimum headway time adopted by passenger cars following passenger cars during a peak 15 min interval, is about 2,180 passenger cars per hour per lane.
