Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] Such as image 3 As shown, the embodiment of the present invention provides a method for distributing personalized traffic information, including the following steps:

[0019] Step 301. Set the road network, the traffic information of each road section in the road network, and the collection of traffic information influence ranges.

[0020] A road network is defined as a collection of road segments:

[0021] L={l|l=}, where id uniquely identifies a road segment, name is the name of the road segment, type and len define the level and length of the road segment respectively, and PrvLinks stores the road segment The id set of directly connected upstream links, because a link may have multiple upstream links.

[0022] Traffic information is defined as:

Abstract

The invention discloses a traffic information issuing method, and belongs to the field of intelligent traffic. The method comprises that: a road network, traffic information of each road segment in the road network, and a set of traffic information influence ranges are arranged; a traffic information influence grade and a broadcast range are arranged according to the traffic information and the traffic information influence range; the traffic information is acquired, and the traffic information influence grade and the broadcast range are confirmed according to arrangement and stored; and the traffic information is broadcasted according to user arrangement. A space-time change model of the traffic information influence range is defined, and influence degree of the traffic information is defined in a grading way; and the traffic information acts as the customized issuing main body so that problems, including differences of the traffic information influence range cannot be adapted, algorithm execution efficiency is poor, etc., which are caused by the fact that vehicles act as the customized traffic information acquisition main bodies in the prior art are solved in one action, and the customized broadcast scheme based on shunting points with great expansibility is given.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method for distributing traffic information. Background technique [0002] With the increase of car ownership in large and medium-sized cities, various traffic problems have become increasingly prominent: traffic congestion, frequent accidents and environmental pollution have brought serious impacts on the economic and social development of cities. In particular, traffic congestion, sudden accidents, control and other situations not only bring a lot of inconvenience to people's travel life, but also cause huge economic losses to the society. In order to solve this problem, in addition to strengthening the construction of road infrastructure and improving laws and regulations, all countries in the world are committed to using advanced computer information processing, electronic communication and wireless network technology to intelligently, comprehensively, real-time, a...
