Solid-State LiDAR for Intelligent Transportation Systems

Solid-state Lidar for advanced traffic management applications

New sensing technologies are meant to play a major role in making our transportation systems more efficient. Indeed, comprehensive connected sensor networks are able to monitor and optimize many aspects of road traffic in real time, such as automated tolling, speed monitoring and enforcement, smart parking, vehicle profiling, and barrier gate controls, to only name a few.

Today, a new generation of high-performance LiDAR based on solid-state designs is emerging, delivering range, resolution, and reliability at a much smaller cost and format than mechanical scanning LiDARs.

The fast-paced development of LeddarTech’s novel solid-state LiDARs (SSL) have the potential to bring significant benefits to the intelligent transportation systems (ITS) and advanced traffic management system (ATMS) industries.

Advanced Traffic Monitoring

With excellent lateral positioning and object discrimination in its field of view, a Leddar sensor compiles measurements hundreds of times per second to accurately locate vehicles of all sizes, including bicycles and motorcycles, as well as pedestrians. Robust signal processing ensure consistent detection in all environmental conditions, for efficient traffic management year round.

Leddar-based traffic management systems provide accurate stop bar functionalities and advanced vehicle detection. Installed above the ground, such as on existing traffic light posts, they efficiently replace traditional induction loop sensors.

Vehicle Measurement and Profiling

Data collected by Leddar sensors can be used to profile vehicles of all shapes and forms, thanks to the sensors’ ability to measure several segments (in 2D configurations) or multiple pixels (in 3D configurations) with high sampling rates in a given field of view. This provides the capability to estimate the dimensions and shape of moving vehicles and then classify them or validate their characteristics against application-defined criteria. Leddar sensors can therefore be used to design high-performance, cost-effective systems requiring vehicle classification by size and type.

The capacity to measure vehicle dimensions or to classify them make SSL sensing a very interesting technology to integrate into a variety of applications such as gated access control systems, clearance warning solutions for overpass, tunnels or parking, and public transit priority systems.

Automated Tolling (e-toll)

SSLs represent a versatile sensing technology to enable e-toll applications, replacing traditional toll booths by automated systems placed on gantries above streets and highways. As part of automated tolling systems, the LiDARs detect each incoming vehicles in every lane, triggering automatic licence plate recognition systems (ALPR) feeding the data to automated toll collection solutions. More sophisticated SSL-based systems can also provide vehicle profiling and measurement capabilities.

Speed Enforcement and Mitigation

A single Leddar sensor can provide single-point speed measurements with a very small error margin, and discriminate multiple vehicles in its field of view. SSLs can also be used in traffic calming systems by providing drivers with their actual speed.

Two-point average speed measurement systems can also be developed using two Leddar detection units that detect the vehicles at entry and exit points over a given distance (allowing to calculate the average speed). An external camera-based ALPR module can be triggered to capture each passing vehicle’s license plate, for example. Leddar-based speed enforcement systems enable the average speed calculation with a 3 km/h accuracy margin, for vehicles going up 250 km/h.

CUSTOMER STORY: TRAFFICLOGIX

Advanced Detection Technologies LLC have developed a global expertise in access control and under vehicle inspection solutions that are used worldwide for perimeter security applications.

When initially designing the LowCam systems, Advanced Detection’s development team was faced with the challenge of finding the right sensor to accurately detect passing vehicles.They rapidly found out that the LeddarOne outperformed both ultrasound and other optical sensors when confronted to harsh conditions, such as rain and extreme light conditions.

After months of research and testing, we found the LeddarOne to outperform not only LiDAR competitors but also other forms of detection, such as ultrasonic, radar, laser, and video analytics.” – Robert Durish, Software Engineer, Advanced Detection
