Abstract
The invention provides a method for displaying traffic condition in real time by a satellite positioning and navigating system, and relates to urban traffic intelligent management. A road traffic signal controller is provided with a multifunctional communication module, wherein the module is matched with a communication circuit of a satellite positioning system; the multifunctional communication module and the communication circuit exchange data through a communication protocol; after the satellite positioning system receives the data, the data is analyzed through a data analysis circuit; the analyzed data is transmitted to a satellite navigating device; the satellite navigating device displays the traffic condition of the required area to a vehicle driver according to user requirement; and the driver determines driving route and speed independently according to the road traffic condition displayed by the navigating system. The method has the advantages that real-time information of the road traffic controller and the satellite positioning and navigating system are combined together, the prior functions of the satellite positioning and navigating system are sufficiently utilized, and the deficiency that the satellite navigating system cannot display the traffic condition is overcome. The method plays an active role in urban traffic management.
Description
Technical field
The present invention relates to the method for urban transportation intelligent management, particularly utilize satnav and navigational system to show traffic behavior in real time, the method for person's traffic that demonstration in time informs the vehicle driving.
Background technology
Along with the progress of expanding economy and society, it is ripe that urban traffic control constantly is tending towards.Adopting high-tech intelligent management means is to improve the sign of Modern Traffic management level.Satnav and navigational system are incorporated into Long-distance Control and the supervision that has solved vehicle conscientiously after the traffic administration, to strengthening vehicle management, relieve traffic congestion, guarantee vehicle safety, keep the peace, prevent that generation or the like the aspect of great malignant event from all having played very great positive role.Particularly the utilization of satellite navigation system provides many convenience for modern's trip.Yet, the management of satnav and safety practice all rest under the state of monitoring and disposal afterwards substantially, though monitoring, guide means is very advanced, but, traffic participant, particularly automobile driver can not be predicted the road ahead traffic in advance, can not be in advance according to the road traffic condition design of the best, arrange traffic route, know " dead end " to such an extent as to arrived the place of traffic jam, rerouting of road there's not enough time.The effect of electronic chart is also just played in satellite navigation, does not have the demonstration of road traffic condition.Like this, be very difficult to fundamentally solve the situation of urban traffic congestion.If can make full use of advanced satnav and navigational system, the guiding automobile driver is according to real-time traffic states, active adjustment travel route and speed, avoid the crowded circuit of road in advance, so just passive management can be become the aggressive organic management that the driver participates in directly, state congested in traffic, that stop up just may effectively solve.Along with high-tech propelling, satnav and navigational system are applied in each city traffic management more and more, effectively improve the effect of satnav and navigational system, give full play to the function of satnav and navigational system, making it better for the urban transportation service, should be an effective and simple and direct approach.
Summary of the invention
The purpose of this invention is to provide a kind of traffic signaling equipment and satnav and organic method that combines of navigational system utilized, realize that satnav and navigational system are to the automobile driver displaying traffic condition in real time, make the driver predict condition of road surface in advance, ACTIVE CONTROL and change traffic route and speed, the organic management urban highway traffic, change that domestic car is many, the people is many, the present situation that road is not smooth.
The object of the present invention is achieved like this: the method for a kind of satnav and navigational system displaying traffic condition in real time, it is characterized in that: the multifunctional communication module is installed on road traffic signal controller, the communication part of this module and global position system is complementary, the two carries out exchanges data by communications protocol, after the receiving circuit of global position system receives data, by the data parsing circuit data are resolved, data after the parsing send to the satellite navigation part by transtation mission circuit, satellite navigation is shown to satellite navigation receiver on the motor vehicle according to user's needs with the traffic of desired zone, the road traffic condition that automobile driver shows according to navigational system is determined traffic route and speed voluntarily.
The traffic communication data exchange of road traffic controller and NAVSTAR comprises the phase place longitude coordinate, the phase place latitude coordinate, the green state of phase place reddish yellow, enter the stage, number of phases, the current operation period, be about to the operation phase, operation phase last time, green light excess time current generation, green light excess time next stage, the current period time, current operational version, the operation virtual time, phase place working time, coil vehicle queuing situation, coil-induced, flicker variable etc.
Advantage of the present invention is: existing satnav and navigational system, there is not the traffic signals interface protocol, and can not receive and launch Traffic Information, make satellite navigation system can only play the navigation function of electronic chart.The present invention combines the real-time information of road traffic controller with satnav and navigational system, make full use of the function of existing satnav and navigational system, on the basis of electronic chart, show road traffic condition and in time automobile driver being shown dynamically, in real time, filled up the deficiency that satellite navigation system can not show traffic.Simultaneously, passive traffic administration become that traffic participant and supvr initiatively participate in dynamically, three-dimensional management, very positive effect has been played in urban traffic control.
Description of drawings
Fig. 1 is the connection diagram of road traffic controller and satnav and navigational system;
Fig. 2 is the workflow diagram of the embodiment of the invention.
Embodiment
Below in conjunction with drawings and Examples the present invention is described further.
Road traffic signal controller uses TACT32 regional coordination controller.The multifunctional communication module is installed on the machine, adopts the TCP/IP communications protocol, can not only network and concentrate multimachine to coordinate, also can be complementary, carry out exchanges data by communications protocol and global position system with the communicating circuit of global position system.Global position system receiving circuit via satellite receives data, and the data after parsing radiating circuit via satellite send data to satellite navigation system.Not only comprise real-time red greenish-yellow three look traffic signal state in the data, also comprise the detected parameter of various detecting devices in the road traffic signal controller.Detecting device comprises coil checker, Video Detection, infrared, ultrasound wave, less radio-frequency detecting device etc.These data exchange in the global position system simultaneously, as, the detected coil vehicle queuing of coil checker situation, coil-induced, flicker variable.The data such as real-time red greenish-yellow signal lamp conversion time of exchange timer record also exchange in the global position system simultaneously.
In the present embodiment, TACT32 road traffic signal controller and global position system communications protocol partly are shown with C language data structural table:
