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.

AEye’s 4Sight™ M Addresses Perception Sensor Challenges

AEye’s 4Sight™ M is a software-defined lidar sensor that leverages AEye’s Intelligent Sensing Platform to enable perception to better locate, identify and track objects over time. It is specifically designed to complement the use of existing cameras, radars, and loops in Smart Intersection applications, improving data collection and overall safety for road users and pedestrians.

  • Enables faster, more accurate and reliable perception up to 300m
  • Extends sensing capabilities of existing Smart Intersection applications — improving pedestrian safety and traffic flow
  • Performs in all lighting and weather conditions
  • Provides high density data in heavy traffic conditions — enhancing traffic controller efficiency
