Line Marking Condition Surveys & Maintenance Program Development
Line marking condition surveys provide an objective, network-wide view of line marking performance. This data allows road managers to identify where markings are no longer providing adequate visibility and prioritise re-marking where it will deliver the greatest safety benefit.
RSDH helps road managers move from reactive remarking cycles to evidence based maintenance programs using vehicle mounted reflectometer surveys. Vehicle mounted reflectometer surveys provide an objective, network-wide view of line marking performance. This data allows road managers to identify where markings are no longer providing adequate visibility and prioritise re-marking where it will deliver the greatest safety benefit.
By measuring retroreflectivity across the network at traffic speed, we identify sections where long lines (edge, lane, centre lines) no longer meet performance requirements as per the Australian Standard, or your road authority or maintenance contract requirements.
​
We use the line marking survey condition data to identify and prioritise re-marking based on condition and, if required, traffic exposure, road environment and crash risk. This approach ensures limited maintenance budgets are directed to the locations that most influence driver guidance, nighttime visibility and overall crash risk. The result is a defensible, data driven remarking program that improves network consistency, supports compliance with performance based specifications, and delivers safer roads without increasing overall maintenance expenditure.
Line marking condition data collection benefits
Line marking reflectivity condition surveys are commonly used by road authorities and contractors to undertake network-wide line marking performance surveys. The benefits for road managers include:
​
-
Affordable and Safe data collection at traffic speed.
-
Collection during the day or night, depending on road accessibility.
-
Objective measurement of line marking visibility against the Australian Standard retroreflectivity requirements.
-
Maintenance cost savings through network level condition mapping and the development of targeted, prioritised remarking programs to achieve retroreflectivity compliance.
-
Improve road safety through maintaining delineation and providing readable lines for Advanced Driver Assistance Systems (ADAS).
