Description
Technical field
The present invention relates to a kind of transport information dissemination method, specifically is the transport information dissemination method that can eliminate the traffic vibration.
Background technology
Traffic information system is an important component part of intelligent transportation system at present; It mainly acts on is that intelligent information is distributed to traveler; Help traffic participant reasonably to select the walking along the street footpath, finally reach the maximization of traveler broad sense cost minimization and road network overall efficiency.
Find that through retrieval the research of relevant transport information issue mainly concentrates on three aspects at present both at home and abroad, the one, make the traveler path optimum through releasing news; The 2nd, be based on the optimum of the current benefit of road network; The 3rd, through aggregate measures, make that simultaneously the traveler path is optimum and the road network benefit is maximum.But two kinds of how-do-you-dos nearly all can appear in these three kinds of methods, and a kind of situation is exactly the more of information issue, and traveler does not know how to select, thereby makes whole structure not give full play to; Most important a kind of situation has provided comparatively responsive information; Impel so more traveler in short selection of time same path; Thereby make traffic congestion transfer on this so-called optimum road from other roads, produced the traffic oscillatory occurences, the result is just the contrary.
Summary of the invention
The objective of the invention is for overcoming the deficiency of above-mentioned prior art; A kind of transport information dissemination method that can oscillation-damped is provided; This method makes in traffic circulation; Not only can make simultaneously that the traveler path is optimum and the road network benefit is maximum, and can guarantee in time that road grid traffic operates steadily, the least possible appearance traffic vibration.
For realizing above-mentioned purpose, the present invention adopts following technical proposals:
A kind of transport information dissemination method that can oscillation-damped, step is following:
1) traffic flow checkout equipment, recording traffic stream information parameter are installed on all Traffic monitoring points;
2) adopt the anti-push technology of OD to calculate the vehicle driving OD information at shunting node place;
3) calculate highway section expected load degree; And judge with alternative highway section load of machinery systems contrast;
4) through the amount of fluctuating of driver's IR Model Calculation information issue, between structure information issue dynamic area, release news with this.
Said step 2) concrete grammar is: with any one node in the road network and peripheral road network is the unit, when traveler arrives the O point, face the m kind and select, and total n of final destination, wherein, m, n are natural number; According to the telecommunication flow information that is detected on the highway section in the step 1), adopt the anti-push technology of maximum likelihood OD can try to achieve travel amount from starting point to any one terminal point.
The concrete grammar of said step 4) does
