There are two technical paths to realize automatic driving: bicycle intelligence and vehicle-road coordination. Many areas in China have chosen the vehicle-road coordination scheme. Vehicle-road coordination refers to the establishment of an interconnection system between cars and roads, so that they can realize instant communication and data exchange in order to work better together. Compared with the bicycle intelligent scheme, road coordination can not only greatly increase the detection range and reduce the calculation burden on the vehicle side, but also make automatic driving easier, lower the cost, provide more information and have greater upgrade potential.
Intelligent vehicle infrastructure cooperation system can be widely used in public transportation, taxis, private cars, logistics and other vehicles. For example, public transportation can provide real-time bus arrival information and navigation services through this system, reducing the waiting time of passengers; Private cars can provide real-time driving assistance services and parking space information through this system, which can improve driving safety and parking efficiency. Logistics transportation can provide real-time goods tracking and distribution services through this system, and improve logistics efficiency.
Components of vehicle-road coordination
1. Vehicle-mounted terminal: installed on the vehicle, used to collect data such as the position, speed and direction of the vehicle and transmit the data to roadside equipment or traffic management center.
2. Roadside equipment: installed on the road, used to communicate with vehicle-mounted terminals, collect vehicle data and transmit road information to the traffic management center.
3. Traffic Management Center: It is responsible for collecting and analyzing traffic data, identifying abnormal road information, and synchronizing the information to on-board terminals of other vehicles to provide real-time road information and driving assistance services.
4. Data center: store and manage traffic data and provide data support for traffic management center.
5. Application system: Based on traffic data and road information, provide various intelligent traffic application services, such as real-time navigation, intelligent parking, traffic signal optimization, etc.
