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 automated traffic management, to name a few.

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

LeddarTech’s novel solid-state LiDARs (SSLs) bring significant benefits to the intelligent transportation system (ITS) and advanced traffic management system (ATMS) industries.

Featured Applications

LeddarVu for ATMS

Advanced Traffic Monitoring

With excellent lateral positioning and object discrimination within the field of view, Leddar sensors compile measurements at a rate of hundreds of times per second to accurately locate vehicles and objects of all sizes, including bicycles, motorcycles and pedestrians. Robust signal processing ensures consistent detection in all environmental conditions for efficient year-round traffic management.

Leddar-based traffic management systems provide accurate stop bar functionalities and advanced vehicle detection. Installed on above-ground fixtures such as 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 sizes 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 ability to estimate the dimensions and shapes of moving vehicles, and subsequently classify them or validate their characteristics according to 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 or classify vehicle dimensions makes SSL sensing a very promising technology that can be integrated into a variety of applications, including e-tolling, gated access control systems, and clearance warning solutions for overpasses, tunnels and parking.

Automated Tolling (e-Toll)

SSL is a versatile sensing technology that can be integrated into automated systems to enable e-toll applications. These above-ground systems can be placed on street and highway gantries, effectively replacing traditional toll booths. As part of an automated tolling system, the LiDARs detect all incoming vehicles in every lane, triggering automated license plate recognition (ALPR) systems that feed the data to automated toll-collection systems. The most 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 margin of error and discriminate multiple vehicles within its field of view. SSLs can also be used in traffic calming systems to notifiy drivers of their actual speed.

Two-point average speed measurement systems can also be developed using two Leddar detection units that detect vehicles at entry and exit points over a given distance (enabling calculation of 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 average speed calculation with a 3 km/h accuracy margin for vehicles travelling up 250 km/h.
