Traffic has always been a major headache for urban areas. Increased vehicular traffic has environmental impacts on cities, leading to more polluted air and fuel inefficiencies. The problem will become more serious in the future, as the number of city-dwellers continues to increase. The World Economic Forum estimates that about 65 percent of the world’s population will live in cities by 2040. More people living in cities leads to urban traffic congestion, along with more pollution and a higher number of accidents.

According to the National Safety Council (NSC), speeding was a contributory factor in more than one-quarter (26 percent) of traffic deaths in 2019, killing an average of 25 people each day. For cities and traffic planners, reducing accidents and protecting pedestrians and other motorists and their passengers from harm is critical.

On highways, radar and patrolling troopers monitor drivers’ traveling speed. However, within an urban environment, keeping tabs on driving behavior can be more challenging. In the past, cities relied on traffic lights and measures to reduce the number of vehicles on the road to manage traffic. Today, however, smart connected technologies can help cities track speeding vehicles and assist with traffic management systems.

Traffic cameras have become ubiquitous in many urban areas, used for collecting data to help cities deal with their vehicular issues. By combining cameras with smart technologies, solutions can provide cities not only with information, but can enable them to gain insights for informed decisions.

Intelligent Transportation Platform

One solution for smart cities is the Parifex NANO-CAM, a sensing solution for intelligent transportation, advanced traffic management, and vehicle profile and speed enforcement. The solution uses Light Detecting and Ranging (LiDAR) technology, a remote sensing method that incorporates a pulsed laser to measure variable distances. Lidar targets an object with a laser and gauges the time for the reflected light to return to the receiver. 

Parifex is one of the largest providers of smart systems for the French government. With a 25-year-plus history in the field, the company has experts in video analytics, IT development, artificial intelligence (AI), and image processing. Parifex has a division that focuses on smart city management. Parifex is a partner in the Intel® IoT Solutions Marketplace, and the NANO-CAM solution uses 6th Generation Intel® Core™ i7 Processors.

Mobile Enforcement

NANO-CAM can be used in several ways. The solution can be used as a mobile enforcement system on a tripod. It can be integrated in other systems as a measurement tool, and it can also be used as a traffic data collection tool. By using 3D LiDAR technology to model the environment, NANO-CAM collects precise real-time traffic data and detects any moving target in its field of view. The system can count and classify vehicles and determine their precise position by tracking the vehicle’s speed, direction, and proportions.

For speed enforcement, NANO can be integrated into testing areas, classifying  and identifying specific vehicles. Another use case is to help further autonomous vehicle usage. NANO’s sensors can be used to improve vehicle environmental perception and support autonomous vehicles’ ability to make better risk analysis to help navigate specific traffic situations, such as roundabouts. The 3D LiDAR-based system works in all weather conditions and during the day and at night.

Combining LiDAR technology with a camera, and incorporating AI and image processing, the NANO-CAM can perform red light and stop sign enforcement and speed detection, for instance. It can also monitor pedestrian and cyclist activity, cell phone and seat belt use. 

The NANO-CAM comes with user software that has a user-friendly API for Windows. Sensors can easily integrate with various applications such as smart parking, autonomous vehicles projects, and security.
