Lane changing behaviour of heavy vehicle drivers.

Lane changing models are an essential component of any microscopic traffic simulation software. Microscopic traffic simulations are mostly using a general lane changing model to estimate lane changing behaviour of heavy vehicle and passenger car drivers. The parameters of the general lane changing model are calibrated for heavy vehicles and passenger cars, separately. However, heavy vehicle and passenger car drivers may have fundamentally different lane changing behaviour. A reliable model is developed in this research to estimate the lane changing behaviour of heavy vehicle drivers. The performance of the heavy vehicle drivers lane changing model is examined using VISSIM. The results of this research shows that developing an exclusive lane changing model for heavy vehicle drivers can increase the accuracy in estimating the number of heavy vehicle lane changing manoeuvres as well as estimating the macroscopic traffic measurements.
