SINGAPORE – To upgrade the way it manages the 9,500 lane-kilometres of road under its charge, the Land Transport Authority (LTA) is calling for ideas to measure and predict road maintenance needs.

Separately, it is also calling for proposals to improve the way roads are designed and constructed.

At present, it uses a mix of video analytics and artificial intelligence to spot defects on road surfaces. The use of such technologies has improved productivity and detection accuracy, LTA said in a document posted to its website calling for solutions.

LTA uses three types of specialised equipment to assess road performance today. A laser crack measurement system evaluates surface roughness, ruts (or tracks left by wheels), surface texture and cracks; a grip tester assesses skid resistance; and a falling weight deflectometer looks at the structural integrity of the roads.
