On December 11, 2025, AutoNavi Maps made an announcement about the nationwide launch of its 'Subway Congestion' navigation function. This function gives a real - time display of the congestion levels for each subway line and train. It utilizes a heatmap to present the information, and the entire network's data is updated every minute. The congestion levels are divided into five categories: not congested, relatively not congested, moderately congested, relatively congested, and highly congested. To assist users in steering clear of peak hours, there are both color - coded and text - based prompts. At present, this function encompasses 90% of the subway stations. Users can access it in two ways. Firstly, when planning a route, they can enter their departure and destination points, choose public transportation as the mode, and then view the congestion information. Secondly, they can search for 'subway map' on the app and click 'congestion' to check the congestion status of the entire city's subway network. Moreover, on December 2, AutoNavi Maps also introduced a real - time dynamic parking space function (exclusive to users in Beijing). This function filters nearby parking space information according to the user's location and offers an accurate depiction of available parking spaces.
