The research found:
- LDW systems are capable of providing appropriate warnings in rural road environments where there are suitable line marking; and
- Line markings on WA roads (where they have been well maintained) are suitable for detection by LDW systems.
The research recommended the trial be expanded to more remote roads in WA and the need to consider future maintenance programs for line markings as they relate to the further expansion of the automated vehicle technology along the regional and remote network.
Road safety benefit:
The research is beneficial to Government to the extent that the findings of this study show that LDW systems are capable of providing appropriate warnings in rural road environments where there are suitable line markings. It was clear that the line markings being utilised on WA roads, where they have been well maintained to provide sufficient levels of contrast with the road surface and retro-reflectivity, comfortably meet this level of suitability.
