Embodiment Construction
[0020] The present invention provides a method for providing dynamic traffic information services based on layer overlay. The method provides users with dynamic traffic based on layer overlay through the cooperation of the basic GIS server providing basic GIS services and the road condition information server providing road condition information tile maps. information services;
[0021] The workflow of the basic GIS server includes the following steps:
[0022] Step 1.1: Start the service and wait for the traffic information service request from the user;
[0023] Step 1.2: After receiving the traffic information service request, send a traffic picture request to the traffic information server, apply for a traffic information tile map under a certain scale and within a certain latitude and longitude range, and then wait for the feedback from the traffic information server;
[0024] Step 1.3: After receiving the road condition information tile map returned by the traffic infor...

The invention relates to the technical field of traffic information service and particularly relates to a dynamic traffic information service providing method based on the map layer overlapping. The method includes that a basic geographical information system (GIS) providing basic GIS service and a road condition information server providing a road condition information file map are matched in work, the basic GIS server receives a user request and applies for the road condition information tile map with certain proportional scale and longitude and latitude range, the road condition information tile map and a local basic CIS map are overlapped to obtain a traffic information map after feedback is obtained, and the traffic information map is fed back to a user to be displayed. The road condition information server timely acquires newest real-time road condition data, conducts road condition rendering, generates a road condition information tile map, stores the map, then receives a road condition map request, extracts a corresponding road condition information tile map from a storage catalogue, and returns the map to the basic GIS server. By means of the method, overlapping efficiency and accuracy of traffic information to common maps are improved.
Description
technical field [0001] The invention relates to the technical field of traffic information services, in particular to a method for providing dynamic traffic information services based on layer overlay. Background technique [0002] Under the guidance of the market economy, most industrialized countries have experienced the process of economic development promoting the development of automobiles, and the development of the automobile industry has stimulated the process of economic development, so these countries have realized the era of automobileization as early as possible. Social problems such as traffic congestion, traffic accidents, energy consumption and environmental pollution brought about by the automobile society are getting worse day by day. The mode of thinking to meet the demand has turned to the technology and method of joint management of supply and demand to improve the increasingly acute traffic problems. These industrial countries built on the wheels of the ...
