Method for acquiring surrounding road conditions by mobile terminal

Abstract

The invention discloses a method for acquiring surrounding road conditions by a mobile terminal, which relates to the method for acquiring information from a service center by the mobile terminal. The method comprises that: the service center records mapping relationships between road sections in an electronic road condition map and the road sections in a standard electronic map into a road condition table; the service center periodically updates the road conditions in the road condition table; the mobile terminal generates a road condition request comprising current position coordinates and a searching radius, and transmits the road condition request to the service center; the service center finds all the road sections meeting conditions and numbers thereof from the standard electronic map according to the road condition request, further extracts road condition states of all corresponding road sections from the road condition table, and finds congested and crowded road sections from all the corresponding road sections; the service center generates textual description information comprising the names, congestion or crowding of the road sections for the congested and crowded road sections; the service center returns the textual description information to the mobile terminal; and the mobile terminal displays the textual description information. In the method, high processing speed and small data traffic are ensured, and the mobile terminal is free from the influence of electronic road condition map sorts.

Description

technical field [0001] The invention relates to a method for a mobile terminal to acquire information from a service center. Background technique [0002] With the rapid development of China's economy and the rapid increase of urban population, the increasing traffic congestion has become one of the key problems that need to be solved urgently in urban development. One of the most effective ways to solve urban traffic congestion using modern information technology. In the early days, most of the traffic command centers with real-time road condition collection and display functions took the city as a unit, collected the traffic information of the city in real time, and reported the current road conditions of the city's roads (such as congestion, blockage, smooth flow, etc.) etc.) in different colors (such as red, yellow, green, etc.) on the electronic map display screen of the command center. At present, there are more and more individuals and groups that need real-time tra...

Problems solved by technology

[0004] However, the service center responds to the request of the mobile terminal, cuts the electronic map of road conditions for it, obtains the electronic map of road conditions in the area designated by the user, and directly forwards it to the mobile terminal of the user. This method has the following disadvantages: (1) downloading to the mobile terminal The traffic of the traffic electronic map in the designated area of ​​the terminal is heavy; when multiple users request to download at the same time, the workload of cutting the traffic electronic map is heavy, the download delay is relatively long, and the traffic status color bar of the road section on the mobile terminal has a phenomenon of pause

(2) The mobile terminal must support the road condition electronic map display function, otherwise it cannot display real-time traffic condition information

When mobile terminal users need to travel between multiple cities, the electronic map of traffic conditions in all cities cannot be supported
