Traffic information distribution method capable of eliminating oscillation

Abstract

The invention discloses a traffic information distribution method capable of eliminating oscillation, which includes the steps of: 1) installing traffic flow detection equipments on all traffic monitoring stations to record the parameters of the traffic flow; 2) computing the vehicle traveling OD(Origin-Destination) information at traffic diversion junctions through the OD backstepping technique; 3) computing the expected load level of a road section and estimating and comparing the expected load of the road section with the load level of an alternative road section; and 4) computing the fluctuation of the distributed information through a driver stimulation reaction model and building an information distribution dynamic area to distribute the information. With the method, the routes of the travelers can be optimal, and the benefit of the road network can be the maximum at the same time, smooth traffic circulation of the road network is ensured in time and traffic oscillation is reduced as much as possible.

Description

technical field [0001] The invention relates to a traffic information release method, in particular to a traffic information release method capable of eliminating traffic oscillation. Background technique [0002] At present, the traffic information system is an important part of the intelligent transportation system. Its main function is to release intelligent information to travelers, help traffic participants to choose travel routes reasonably, and finally achieve the minimization of traveler's generalized cost and the maximization of the overall benefit of the road network. change. [0003] Through searching, it is found that the current research on traffic information release at home and abroad mainly focuses on three aspects, one is to make the traveler’s route optimal through the release of information; the other is to optimize the traffic efficiency based on the road network; At the same time, it makes the traveler's path optimal and the road network benefit maximum...

Problems solved by technology

However, there are almost two embarrassing situations in these three methods. One situation is that there are too many information releases, and the traveler does not know how to choose, so that the overall effect cannot be fully exerted; the most important situation is to provide more sensitive information. In this way, more travelers choose the same route in a shorter period of time, so that traffic congestion is transferred from other roads to this so-called optimal road, resulting in traffic oscillation, and the result is counterproductive.
