Smart road surface makes merging more efficient
Rijkswaterstaat (the Dutch department of Waterways and Public Works) used a special variety of USE’s DRM (Dynamic Lane Marking) system for an experiment called “Smart road surfaces: electronically guided merging”. Part of a national innovation programme, this experiment was aimed at determining whether merging traffic from three to two lanes would be more smooth if motorists can follow “walking lights”. Theoretically, by following the lights motorists would automatically keep sufficient distance to facilitate merging. Practical tests on the A9 and A44 motorways showed that our electronic guides do indeed make merging smoother and safer. As the average speed drops and velocity differences are minimized the general flow of traffic is promoted.
