Implications of pavement markings for machine vision

Abstract

This report examines how longitudinal pavement markings affect automated steering functions and whether changes to design and maintenance practices could improve the support lane markings provide for current advanced drivers assistance systems and future automated vehicles. Vehicles with more automated features, including Lane Keeping Assist, are gradually being introduced into Australia and New Zealand. Lane Keeping Assist has been shown to have road safety benefits, especially on rural roads. Automated steering functions rely on machine-vision systems which use pavement markings and roadside features, such as kerbs and shoulders, to align the vehicle to the road. The report documents the results of a literature review, stakeholder consultation, on-road and off-road evaluations and data analysis. It includes preliminary costings of key recommendations to allow agencies to understand the benefits and impacts of modifying line and lane marking practices.
