Problems solved by technology
[0003] First of all, the general congestion information provided to the public is mostly the location of the congestion information point, and the lack of traffic on which road sections caused the congestion of a certain road section, that is, the distribution of the source of the congested road section in the city
Secondly, how to accurately send congestion information to the public who may enter the congested road section is still insufficient, that is, the congestion information is often reported widely in the city, and cannot be conveyed on different road sections in the city according to a certain priority

Embodiment Construction
[0042] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
[0043] In order to solve the problem of global and local most relevant, the present invention utilizes the community division method in the complex network to solve it. The community division method is mainly used to reveal a technology of network aggregation behavior, which is actually a method of network clustering. The "community" here can be understood as a collection of nodes with the same characteristics. If the road network and traffic trajectory data can be established as a complex network between road segments, then the community division method of road segments can be divided into different internally connected communities. Each community belongs to "local correlation", and the road sections in all communities belong to "global correlation".
[0044] The inventive method is specifically as follows:
[0045] Step 1) See attached figure...

The invention discloses a method for targeted delivery of urban traffic congestion information. Roads in a studying area are preprocessed; a traffic travel record data set is formed and is marked as GJ; a relationship network between urban roads is determined based on the GJ; and then the main associated section information of an urban traffic congestion section is calculated. Therefore, the urbancongestion information can be transmitted to the most relevant section accurately and the traffic congestion information can be transmitted in a global and local priority order, thereby providing thedecision-making basis for urban planning and traffic management.
Description
technical field [0001] The invention relates to the technical field of urban planning and urban traffic, in particular to a method for targeted delivery of urban traffic congestion information. Background technique [0002] Traffic congestion is an important urban disease at present, which involves the physical and mental health of every urban resident and has a serious negative impact on urban development. The collection, processing and timely dissemination of traffic congestion information to the public is an important means to solve the problem of urban congestion. At the same time, with the advent of the era of big data, the use of big data to study the characteristics of human space activities is becoming more and more extensive. In the field of urban traffic congestion, researchers use data such as mobile phone movements and shared car travel trajectories to calculate which roads in the city belong to congested areas, and inform urban residents of the congested areas....
