Software-Defined Lidar Solution for Smart Intersections
Smart Intersections are designed to reduce congestion, pollution, and fuel consumption, while ensuring maximum safety for pedestrians and road users. However, legacy sensors such as cameras, radars, and loops, have severe limitations. Cameras struggle to detect vehicles at long range, in low luminosity and adverse weather, and do not provide privacy to pedestrians. Radars cannot effectively detect vehicle class in high traffic environments. Legacy sensors lack the versatility to effectively support and deliver dilemma zone protection, signal priority, signal phase extension and other advanced Smart Intersection applications.
