Long Line Retro Data Collection and Re-marking Programming for TMR Sealed Road Network

About

Transport and Main Roads awarded a contract to ARRB for long line retro data collection and re-marking programming on TMR's sealed road network.

The project involved collecting delineation condition data, analysing it with consideration of condition and the road priority matrix in the TMR Element 24 management plan, and assessing road safety risk in dry and wet environments to model a draft repainting program.

The quantitative data approach enabled model-based repainting programming that considered safety risk to identify roads as candidates for delineation providing wet weather performance (e.g., wet weather performance line marking paint/beads and/or raised reflective pavement markers) and identification of homogeneous segments within road segments that require repainting or may be candidates for a more durable paint/bead option.

The contract value was AUD 1,039,500, procured through a limited method.
