The countdown function of traffic lights in map navigation software is actually very accurate and reliable, with almost zero delay. This is because it is connected to the traffic management information platform and uses the technology of 5G and car networking. Principle of countdown to traffic lights in map navigation
Cao Jie and Li Na, the data of the traffic control department, wrote a paper "Yantai: Building a Talking Traffic Light" in the magazine "Road Traffic Management" and told a case. The Traffic Police Detachment of Public Security Bureau of Yantai City, Shandong Province, combined with Gaode Map, created a solution of "traffic signal information push". Through the open signal platform, the traffic police detachment reads and summarizes the data of 235 networking signals in urban areas, and then pushes them in real time with the help of internet navigation software. It is not necessary to remember that the countdown data comes directly from the traffic control department. How can it be inaccurate? The authority and accuracy are guaranteed. Unless the internet speed is a little lower, it will be a little different, a few seconds? The application of 5G and car networking technology, directly connected from the traffic control department, is directly related to the current development of 5G and car networking.
What benefits can the countdown function of traffic lights bring? The countdown function of traffic lights must be good, otherwise who will do it? Save time, reduce violations and improve the overall traffic efficiency of intersections. Moreover, navigation software can broadcast information to our drivers through voice, which can make people prepare psychologically in advance and greatly reduce the probability of violating the rules by running a red light.
Relieve the anxiety of traffic participants. In addition, this function can also alleviate our anxiety in traffic jams. Is the countdown function of traffic lights reliable? Because of the great demand for new technology and networking with traffic control platform, this function is only piloted in several cities at this stage. According to the official announcement of Baidu Map: During the National Day in 2020, Beijing, Changsha, Baoding, Zhengzhou and other cities took the lead in launching this new function. Gaode map has also been piloted in Yantai, Wuxi and other cities, and it is not universal. However, as far as the use of pilot cities is concerned, because the data itself is obtained from the government and can be synchronized almost in real time, it is relatively reliable, and people who have used it feel that the experience is ok.
