Abstract

Lane changes have a significant impact on the characteristics of traffic flow. Lane changing models are therefore an important component of microscopic traffic simulation tools. Existing lane changing models emphasize the decision-making aspects of the task, but generally neglect the detailed modelling of the lane changing action itself and only model it as an instantaneous event. However, research indicates that lane changing durations are on average in the order of 5 to 6 seconds. The omission of lane-changing duration from microscopic simulation models may have a significant impact on simulated traffic flow characteristics and on simulation outputs.


This research presents models of the duration of lane changes. These models are estimated using detailed vehicle trajectory data that was collected in naturalistic driving using high mounted video cameras. This thesis presents separate models for the lane change durations of passenger cars and of heavy vehicles and conducts statistical tests for the similarity between the lane change durations of the two vehicle types.
