Vehicle lateral position depending on road type and lane width
Overview
Background & policy context:
In previous studies of barrier separated road types, it was found that vehicle lane position and the amount of lateral wander varied depending on road type and lane width. These variations will have a direct effect on the rate of surface wear and will influence where stresses and strains are distributed in the pavement structure.
Objectives:
The objective of the project was to investigate, quantify and analyse variations of vehicle lateral position and lateral wander on the Swedish road network.
Methodology:
Twenty-one sets of survey data provided information on over 271,000 vehicles. The data was divided into three groups depending on approximate axle track width. Using the survey data, it was possible to calculate and plot the distribution of lateral position (wheel path), the average position, and the variation of lateral position (lateral wander) for each group.
