With the continuous growth of the number of vehicles, how to improve the operating efficiency of vehicles is particularly important. "In view of this situation, Guangxi Dabai Expressway continued to optimize its design during the construction process. Under the joint promotion of Guangxi Jiaotou Group and related construction units, it built and implemented an AI analysis system including highway portal frame models, an intelligent compensation trading system for lanes, and an intelligent unmanned toll station automatic charging system, ensuring the intelligent charging of vehicles from entering the station to leaving the station." Zhang Penggang, head of the Dabai high-speed electromechanical engineering project of China Railway First Bureau Electric Company, said.
Walking out of the Longzhou West Toll Station of Daying Expressway, the vehicle leaving the expressway has just slowed down and is ready to enter the lane gate. The display board in front immediately displays relevant information including the license plate number, entrance location, cost amount, etc. At the same time, the driving bar automatically lifts to signal the vehicle to enter the lane. This is the role played by the intelligent unmanned toll station automatic charging robot. All toll stations in the whole line are equipped with one such smart charging system.
"There is an intelligent portal at the exit of each toll station, which will extract the vehicle information and transmit it to the automatic charging robot terminal set up at the toll station through the network after operation and processing. After being scanned by the camera at the toll gate, it will issue an ETC automatic payment instruction and complete the charging action. This can effectively improve the work efficiency of toll booth employees, liberate valuable human resources from the monotonous work of receiving and sending cards, and use them for flexible work such as special handling, service guidance and emergency support, which greatly reduces operating costs. " Yao Weihong, chief engineer of the project, said.
Many times, drivers often encounter situations that can’t be recognized by the system because the speed is too fast. In this regard, most people’s practice is to slowly back the vehicle and then slowly approach it to be re-identified. In order to prevent this from happening, the intelligent compensation trading system of lane ETC was installed in the process of engineering construction. The system consists of ETC compensation transaction equipment and its driving software. ETC compensation transaction equipment is installed on the information screen of toll booth and connected with lane industrial computer through computer serial port to realize antenna transaction function. The device driver software is installed in the lane industrial computer to realize the interface docking with the charging software. If the ETC antenna in the lane is abnormal, the ETC compensation transaction equipment will run automatically to complete the transaction. The system effectively improves the efficiency of lane ETC traffic and avoids the congestion caused by the failure of traffic.
In addition to the smooth travel through the smart toll collection system, it is also very important to ensure the safe operation of vehicles and effectively avoid the congestion caused by unexpected accidents at high speed. In this regard, in the process of engineering construction, the AI analysis system of highway portal frame models is vigorously promoted, and the features such as models, high-definition panoramic views of car body sides and vehicle structural information are recognized by using visual technology, and the Dovette sign and traffic records of vehicles are obtained and located. At the same time, complete charging vouchers are provided, and the first-time positioning and early warning disposal of vehicle driving information are realized.
"During the construction of Daidai Expressway, all parties involved in the construction fully learn from and use the latest smart equipment, and strive to maximize the travel convenience of drivers and passengers. As an engineering builder, I am also very happy to see the intelligent expressway completed and opened to traffic. A strong transportation country not only needs an excellent team of engineers, but also needs the empowerment of continuously updated scientific and technological achievements. " Zhang Penggang said.
