According to Memes Consulting, Canadian LiDAR developer LeddarTech has developed an innovative solid-state LiDAR sensing patent technology-Leddar after more than ten years, which uniquely integrates advanced light wave digital signal processing and software algorithms to achieve The mass production of solid-state LiDAR sensors provides excellent performance and reliability at a very competitive price.
LeddarTech’s LiDAR sensors have been successfully used in a variety of mobile applications, including automobiles, intelligent transportation systems (ITS), drones, and industrial vehicles. LeddarTech uses its technology to minimize the risk of accidents, alleviate traffic congestion, improve traffic efficiency, and greatly improve people's life safety and quality of life.
LiDAR solutionLiDAR solutions are expected to revolutionize intelligent transportation systems. According to a report by Maims Consulting, LeddarTech recently released the Leddar T16 and M16-LSR intelligent LiDAR sensors, which represents an important step forward for the intelligent transportation system in the future.

In recent years, LiDAR sensor has become a frequent visitor to the "headline" due to its important role in the field of autonomous driving. LiDAR uses laser beams to detect objects and measure distances to help autonomous vehicles recognize obstacles and achieve safe cruising. Recently, solid-state LiDAR has gradually become the focus of the autonomous driving industry because it is stronger, more compact, and more cost-effective than traditional mechanical LiDAR.
Autonomous vehicles need to rely on 3D LiDAR systems, and 2D LiDAR systems can also identify objects and measure distances, and are beginning to seek more and more remote monitoring and surveillance applications. Now, the 2D LiDAR system is ready to make a big splash in the field of intelligent transportation systems.
Intelligent Transportation System (ITS)
Intelligent transportation system can ensure that transportation is more efficient and safer
Intelligent transportation systems can use advanced technologies to solve traffic problems such as congestion while improving safety and efficiency. Common intelligent transportation systems include: traffic light systems that can detect vehicles and pedestrians, pedestrian aisles; free-passing electronic toll collection (ETC), which automatically charges passing vehicles accurately; and provides drivers with digital signs of the optimal route, etc. .
Although many cities and roads have begun to use various forms of intelligent transportation system technology, most of them still have a long way to go to build the most ideal smart city or smart transportation. In the future, the goal of the intelligent transportation system is to automatically send the optimal driving route information to the vehicle, so that the vehicle can cruise more smoothly, safely and efficiently. In cities, intelligent transportation systems also need to improve the efficiency and safety of public transportation, pedestrians, and bicycles, so as to achieve better commuting and more livable cities.
Intelligent transportation systems use sensors to detect and analyze vehicles
Vehicle detection and analysis is an important foundation of intelligent transportation systems. Ideally, vehicle detection sensors need to seamlessly provide accurate vehicle numbers, classifications, speeds, and occupancy conditions without causing any interference to traffic.
At present, intelligent transportation systems, including automatic toll collection systems, usually rely on sensors deployed underground to detect and classify vehicles. Although this kind of underground sensors are currently the most mature and widely used technology, they have many shortcomings: because they are located underground, they will be under pressure, and constantly moving vehicles will reduce the service life of the sensors and the road surface; the maintenance of underground sensors Or replacement usually requires closed lanes for construction, resulting in traffic interruption; most underground sensors can only provide basic vehicle detection and counting information; underground sensors such as induction loops may also be affected by water, snow or ice on the road; In addition, it is difficult for most underground sensors to accurately analyze and classify vehicles.
LiDAR sensors used in intelligent transportation systems
LiDAR systems use laser beams to achieve long-distance detection and object analysis. Therefore, LiDAR sensors do not need to be placed on the road or underground. They can be installed on roads or highways, such as on traffic lights or buildings near the road, to detect and analyze passing vehicles. Therefore, the highly reliable LiDAR system can be used for intelligent transportation, traffic management, vehicle analysis, electronic toll collection and speed measurement.
The electronic toll collection system uses LiDAR sensors for vehicle detection and analysis
Until recently, due to the high cost and complexity of LiDAR sensors, its application in intelligent transportation systems has been limited. More importantly, traditional mechanical scanning LiDAR systems still have difficulties in identifying trailers or trailing cars, black or bright vehicles, and high-speed vehicles. In addition, mechanical LiDAR systems are relatively more susceptible to severe weather, which reduces the overall reliability of the sensor.
Advanced traffic monitoring using LiDAR sensors
LeddarTech provides next-generation LiDAR for intelligent transportation systems
Now, LeddarTech has launched a new generation of high-performance LiDAR for intelligent transportation system applications, which can provide long-distance, high-resolution sensing performance, and has long-term reliability comparable to traditional underground sensors. The newly launched Flash solid-state LiDAR sensor series products, based on LeddarTech's patented technology, can provide better performance, reliability and cost-effectiveness.
The new Leddar T16 launched by LeddarTech is a complete traffic sensor, equipped with a windproof and rainproof housing, specially designed for traffic detection and analysis.
The T16 traffic sensor provides a high refresh rate of 200 Hz, allowing it to more accurately identify fast-moving vehicles and distinguish, for example, a car with a trailer, a car towing another car, and a trailing car behind the vehicle. Accurate vehicle model analysis enables the electronic toll collection system to automatically collect tolls more accurately, thereby improving the efficiency of toll collection. In addition, the T16's weatherproof and rainproof housing enables it to more accurately identify and classify cars, trucks and motorcycles in various weather conditions.
The M16 module provides two configurations according to the lighting method: the classic LED product family and the new laser family. Both series of M16 products are perfectly suitable for outdoor applications: all solid-state design, no moving mechanical structure, wide temperature operating range, all-weather performance, and not affected by changes in light.
The recently released M16-LSR is a compact, cost-effective LiDAR module that can be integrated into current and future systems for applications such as speed measurement, pedestrian detection and collision avoidance. The M16-LSR module combines the detection distance of the LeddarTech Vu8 solid-state LiDAR sensor and the resolution advantages of the M16-LED, which is an intelligent traffic sensor that can provide ideal large-scale, high-resolution and cost-effectiveness. Efficient laser flash lighting, a variety of 2D field of view options, and a refresh rate of up to 100 Hz make it an ideal sensor for identifying urban vehicles, bicycles and pedestrians.
