Smart roads with advanced vehicle-sensing capabilities could be the linchpin of future intelligent transportation systems and could even help extend driverless cars‘ perceptual range. A new approach that fuses camera and radar data can now track vehicles precisely at distances of up to 500 meters.
Real-time data on the flow and density of traffic can help city managers avoid congestion and prevent accidents. So-called “roadside perception,” which uses sensors and cameras to track vehicles, can help create smart roads that continually gather this information and relay it to control rooms.
