Induced Path Generation Algorithm And Space-time Distribution Strategy Based On The Synergy Between Many Terminals

Due to the rapid increase of vehicle and the acceleration of urbanization,a series of traffic problem mainly on traffic congestion issue are more serious.Traffic induction is one of the key technology of intelligent transportation system,in fact traffic induce can balance auto flows on the urban road network,therefore it is regarded as a effective way to solve the congestion problem.The current domestic application of inducing terminal type many,how to coordinated the misleading information,how to generate induced path and how to publish regional induced information is to be solved in time and space.Induced terminal based on the analysis of advantages and disadvantages and applicability,and Internet technique of inducing terminal interaction,on the basis of many was developed based on the characteristics of the guidance system and target induced,composite framework using AD HOC/AP/STA three kinds of communication mode of mutual coupling and terminal detection and interoperability technology inducing terminal synergy mechanism is established.In terms of induction algorithm,through the analysis of classical Dijkstra algorithm,multi-objective utility function by building,dynamic way assignment and optimized search scope to improve the classic algorithms,the improved algorithm by an example to illustrate the improved timeliness and randomness.Sections in the induction of information release strategy,through the establishment of the affected degree of parameters associated with sections based on the correlation matrix judgment to determine the scope of the induced information release space.In addition,the use of three different conditions of VMS information release time calculating model of coupling induction information released time range determination method is established.Finally,according to the time and space features induced information release induce the release process of strategy is proposed.
