The information board on the elevated road will tell the driver whether the road ahead is blocked, so as to avoid the congestion point in advance, and the main medium carrying this information is the LED traffic induction screen; the live video recording in the monitoring center helps traffic managers discover emergencies at the first time and deal with them in a timely manner. The LED traffic induction screen plays a major role; the traffic flow data collected on site provides scientific decision-making basis for municipal experts to transform the road network - it is the LED traffic induction screen that makes this basis public. Based on the summary of construction traffic conditions in various cities, the traffic guidance system of each expressway has been basically completed. The information network covering the entire range of traffic roads, and the main military force that "comes up with ideas" to eliminate traffic jams and ensure smooth traffic in major cities, is the LED traffic guidance screen.
Earlier, major municipal departments took the lead in installing "clairvoyance" - traffic information variable information boards on each traffic road; then, the information boards on the inner and outer ring roads, north-south, and east-west elevated roads in each region were completed, and the traffic guidance system was opened; at present, the construction of each urban expressway monitoring center has been basically completed; at the same time, a real-time broadcast and release system for urban expressway traffic information has been opened. The most intuitive information carrier, LED traffic display, is believed to be widely used at the same time.
The main functions of LED traffic guidance screens:
1. Real-time traffic information 2. Parking guidance information 3. Real-time traffic information 4. Diversified information integration 5. Humanized information services 6. Improved information openness 7. Close contact with the transportation department 8. Can realize the integration of television and radio, and perform intuitive guidance 9. Improve traffic mobility 10. Improve traffic safety 11. Improve the traffic capacity of traffic roads 12. Improve public travel efficiency 13. Improve public service levels 14. Promote and improve traffic control 15. Rapid network centralized release and management
The current regional use form of induction screens
1. Parking induction 2. Road condition induction 3. Instruction induction 4. Instruction signs 5. Government information
6. Intelligence information 7. Traffic publicity 8. Tunnel guidance 9. Toll display 10. Traffic diversion
The use of LED traffic induction screens can increase the average speed of vehicles on traffic roads by 3% or more. The response and guidance to traffic accidents can fully reduce traffic congestion, traffic detention and other problems. Car drivers are the group that most directly enjoys the information services provided by the traffic guidance system. Through the information board installed on the elevated road, the driver can accurately obtain the road information ahead, choose the route in advance, and avoid unnecessary unpredictable phenomena. Tests show that after the activation of the induction system on elevated roads in major cities, the traffic volume increased by more than 5%, the average vehicle speed increased by more than 3%, and the unblocked time increased by more than 7%. While obtaining information with the help of "clairvoyance", drivers can also understand the traffic conditions of elevated roads through "shunfeng ears" - the urban rapid traffic information real-time broadcast and release system provides half-time real-time traffic broadcasts every day, which can avoid the embarrassment of encountering traffic jams after blindly boarding the elevated roads.
The reason why intelligence boards and broadcasts can provide timely and accurate road information is inseparable from the electronic "scouts" who continue to fight on the elevated roads-traffic information collectors. According to reports, sensors are laid 5 centimeters below the expressway surface, and a set of annular detection coils are installed every 400 meters to provide the monitoring center with information such as vehicle speed, road saturation, and road occupancy on average every 20 seconds. At the same time, hundreds of CCTV camera devices located on local expressways also transmit images to the monitoring center.
The traffic management department uses this information to monitor the entire city's elevated roads, discover traffic accidents, vehicle breakdowns and other emergencies at the first time, and promptly publish corresponding information on the information board and broadcast to implement immediate traffic guidance. The first real-time release of LED traffic guidance will play a key role.
Today, traffic information is closely related to people's lives. How to more effectively establish a more intelligent and comprehensive transportation system still requires relevant units and institutions to work together with the general public to ensure the effective and rapid advancement of the revolutionary process of "smart transportation".
