Amap upgrades smart traffic light service: real-world traffic light countdown, real-time calculation of green wave speed

News from this site on November 30, Amap announced today that it has reached cooperation with many official agencies across the country on urban smart traffic light services, to promote the integration of official traffic light data into map navigation products.

According to reports, the cooperation between public security and traffic police agencies in Xi'an, Lanzhou, Quanzhou, Jining, Beijing Yizhuang and other places and Amap will focus on the "sharing, co-governance, and common use" of traffic information The concept of deep integration comprehensively promotes the integration of signal light status information into the Amap Map App, and combines the Beidou positioning, artificial intelligence, smart transportation and other cutting-edge technologies accumulated by Amap to build core computing power to provide users with more accurate and efficient intelligent traffic light services.

For example, when a user is waiting for a red light at an intersection, he is faced with a signal light without a countdown; or in the lane where he is, there is a "tall" bus in front of him, which just blocks the front. Traffic lights... Now faced with these scenarios, use Amap navigation to realize the countdown of traffic lights in the real world and the "mirror" reproduction on the App, so as to "know it well" and alleviate traffic lights The invisible anxiety while waiting at an intersection or while passing by.

In addition, based on more accurate and real-time light status data, the Amap App can also calculate the current real-time location of the vehicle and the distance to the upcoming traffic light intersection. , traffic flow and other comprehensive information, calculates the "green wave speed range" , allowing users to pass one or more signal intersections ahead with "green light" while ensuring driving safety.

Note from this site: "Green wave speed" refers to maintaining this speed to maximize vehicle traffic capacity and reduce the time vehicles wait for red lights at level intersections.

In addition to cooperation at the data and product levels, Amap has also established a normalized communication mechanism with traffic police agencies in many places to integrate real-time traffic conditions Feedback to the signal control system, and combined with artificial intelligence and smart transportation technology for mutual verification and optimization, thus promotes more intelligent and scientific signal light timing and control.

According to inquiries on this site, AutoNavi’s intelligent traffic light service will be launched in May 2022. It is claimed to be the industry’s first red light countdown service that is implemented on smartphones and uses computing power to “predict” second-level changes. . As of now, the number of daily countdown services provided by AutoNavi’s smart traffic lights across the country has exceeded 2 billion.
