Abstract
The invention relates to a research on an RNNS (Road-Net Navigation System). The RNNS is established by seeing a whole road net as a computer network, wherein roads are connecting lines of the network, and automobiles are message packets to be transmitted on the lines, and a transportation junction equals to router equipment in the network. Differently from the computer network, automobiles have lager initiative compared with message packets, and interacting and feedback requirements of road-automobile-passenger are far beyond those of the network equipment and message packets. Therefore, established is a router model and algorithm suitable for the road transportation.
Description
[technical field]
The present invention relates to the research of a kind of road map navigation system (RNNS), especially fully excavate the potentiality of existing road network, improve its handling capacity, is an efficient ways.Set up such road map navigation system (RNNS), the practical value of existing present stage also is the prerequisite and the basis of progressively realizing driving automatically from now on.。
[background technology]
The vehicle that existing road guiding/Vehicular navigation system can be more than one provides its position of going up at the earth's surface, and it can accurately confirm the position of car in road net in arbitrary preset time.A GPS receiver is mounted onboard, receives the signal that is no less than 4 satellites.These signals are used for accurately confirming the position of vehicle, but it possibly suffer accidental interference, as bad weather influence, tunnel and buildings block, ultra-broadband radio Communication Jamming etc.And onboard sensor is generally used for confirming the current location of automobile.Guider is used for importing the destination and shows that the path that arrives the destination is best.At last, all to get into a kind of algorithm, so that realize the location from the information of arbitrary part in these information sources.But this system cost is high, and operating cost is very expensive, and distance is popularized and remained one period, and it is low how to set up a cost in present stage, and effective Vehicular navigation system is the foundation that the applicant proposes this problem.
[summary of the invention]
The technical matters that the present invention will solve provides the research of a kind of road map navigation system (RNNS), and it sets up the road net model that is fit to present road traffic.
For solving the problems of the technologies described above, technical scheme that the present invention adopts is: flow evaluation index and the flow equilibrium algorithm (i.e. " routing algorithm ") of setting up road network.
Compared with prior art, the invention has the beneficial effects as follows: the compression memory of road net model and efficient retrieval; Seek appropriate road network flow evaluation index; Set up suitable road-vehicle interactive mode and feedback mechanism.
[embodiment]
Research adopts theoretical analysis and analogue simulation to calculate the mode that combines, and sets up the road net model and the flow equilibrium algorithm (i.e. " routing algorithm ") thereof of the road traffic condition that is fit to present Chongqing City.
Consider the unidirectional and two-way current characteristic of road, intend and adopt digraph to constitute the road network eigenmatrix that this eigenmatrix will comprise the determinant attributes such as topological relation that mileage, the traffic capacity and circuit connect.Solving under the efficient compression of this eigenmatrix and the prerequisite of calculating fast, setting up one rationally comprehensively and the road network flow evaluation method of easy operating, supporting the core of this research-based on the vehicle flowrate dynamic assignment system of " routing algorithm " with this.
Claims (4)
1. the research of a road map navigation system (RNNS).
2. the technology of intelligent transportation system ITS (Intelligent Transportation System) improves the utilization ratio that has means of transportation and traffic system now.
3. road map navigation system (RNNS:Road-Net Navigation System).
4. road-vehicle-people's mutual and feedback requirements also far surpasses the demand of the network equipment and packets of information, therefore sets up " route " model and an algorithm that is applicable to road traffic.
