According to foreign media reports, nontraffic, an Israeli company, has launched a turnkey traffic management platform that supports both V2I communications and optimized signal control intersections. This system is based on a plug and play artificial intelligence sensor intelligent network, which can transform each signal control intersection into an intelligent intersection. In less than an hour, users can manage traffic flow in real time. This way is in contrast to today's common intersection technologies such as inductive loop traffic detectors, which are installed underground and can sense cars like metal detectors. Moreover, such traffic detectors are also limited by the fixed time schedule of intersections. The image comes from the system of nontraffic, the official website of nontraffic, which deploys AI on the edge of the network, can reduce installation and maintenance costs, and enable intersections to prepare vehicles, not only respond to vehicles. Nontraffic has AI sensors installed in all directions of the intersection. Yoav valinsky, a computer vision researcher, said the device uses NVIDIA Jetson platform and GPU acceleration framework to integrate computer vision and radar, and can process data about 15 times per second. DSRC is a wireless communication channel system between vehicle and infrastructure, and c-v2x technology can allow communication between vehicle, infrastructure and any related entities. Nontraffic's equipment can detect and classify all road users at the edge, including cars, buses, trucks, bicycles and pedestrians. Then, the processed data flows into the optimization engine. The engine is installed in the traffic light control cabinet, which has already been installed in most intersections. Nontraffic sends the data of each intersection to the cloud safely for further processing and optimizing the urban traffic network. The real-time analysis ability of the system provides the function of collision prediction. Ilan ROZENBERG, director of business development at nontraffic, explained that the sensor device calculates the speed, acceleration and direction of the vehicle, so it can infer when the vehicles cannot see each other and when they may collide. Sensors can classify vehicles and give priority to specific road users. If a city wants to give priority to public transport or pedestrians at intersections around the school in the morning of a working day, the city engineer can enter the relevant traffic strategy on the dashboard, and the system of nontraffic will automatically change it. Nontraffic is a member of NVIDIA's inception incubator program. It is currently focused on the U.S. market and has conducted pilot projects in several cities and counties in the United States. Nontraffic reduces delays by 2700 hours per year, and reduces carbon emissions by 33 tons per intersection.
