Abstract
The invention relates to a transit signal priority automation control system capable of carrying out information prompt and a method thereof. Through comparing bus latitude and longitude coordinate information with the latitude and longitude coordinate information of each intersection center, a bus is determined whether to approach the intersection. Through comparing the bus latitude and longitude coordinate information with the latitude and longitude coordinate information of a monitoring point around the intersection, the bus is determined whether to arrive at the monitoring point. When the bus arrives at the monitoring point, a signal lamp control unit immediately makes an intersection signal lamp provide a green light signal for the bus while an image projection unit on the bus projects light color information of the intersection signal lamp and time remaining information on the windshield of the bus so that a driver can conveniently acquire the signal lamp state of the intersection ahead and react quickly.
Description
Technical field
The present invention relates to intelligent transportation control field, be specifically related to a kind of preferential automatic control system of bus signals and the method that can carry out information indicating.
Background technology
City bus is the important component part of green traffic, low-carbon (LC) life, and along with socioeconomic fast development, urban population is more and more intensive, and the problem of blocking up of urban road becomes increasingly conspicuous, and this also becomes the key factor that influences people's living standard.In order to alleviate traffic congestion, satisfy people's trip requirements, public transit vehicle is implemented signal priority control, at home and abroad generally used.
Summary of the invention
Existing Chinese patent document CN 101256717 B disclose a kind of quick public transport vehicle location and traffic signal control method and device based on GPS; The car-mounted device that this device is formed through the modules such as GPS and MCU, RF wireless transmission that are installed on the quick public transport vehicle in real time, automatically sends data to the vehicle location information of the bus rapid transit that obtains ground reception and treating apparatus and carries out the processing that wireless data avoids conflict through the RF wireless transport module of RF wireless transport module by car-mounted device.The ground receiving and processing device is handled the quick public transport vehicle that obtains and the related data information of these 2 positions of traffic signal controlling machine, and calculates relative position coordinates, distance and the vehicle heading etc. of quick public transport vehicle and ground receiving and processing device.Then with these information real-time, automatically send to traffic signal controlling machine; Undertaken in time, switch effectively by the traffic lights of traffic signal controlling machine again the crossing; Be preferably quick public transport vehicle and give way, thereby guarantee that quick public transport vehicle is preferential, current fast.Adopt above-mentioned technology; There is following problem: when the driver of BRT vehicle drives to the crossing; Can not judge that ground receives and treating apparatus whether treated the override requests of oneself; If current demand signal is a green light signals, and will become red light, the driver does not know whether traffic signal controlling machine can keep green light for oneself at once; If current is red light phase, the driver can not confirm traffic signal controlling machine for let oneself preferentially through and rapidly signal lamp is changed to green light; Therefore under above two kinds of situation, when the driver drove to the crossing, being not sure of oneself was slow down to wait for or quicken and pass through, and is in comparatively passive state.
Existing Chinese patent document CN 101334934 A disclose a kind of vehicle mounted traffic displaying apparatus; This device is for being arranged on the traffic signals indicating device of the indication of one in car junction ahead signal; Said indicating device comprises, a display panel, the signal receiving device that is connected with display panel.The loudspeaker that also have a sounding on the said display panel.During use, this device is accepted the data of the traffic lights of junction ahead, and on display panel, shows, if junction ahead is a red light, shows on the display panel that then junction ahead is a red light, and shows counting down of red light, if instead be that green light also is like this.Adopt the vehicle mounted traffic displaying apparatus in the technique scheme; Though can show the state of junction ahead signal lamp; But for the driver; When vehicle arrives the crossing, no matter see that the demonstration of the signal lamp of junction ahead sees that still the signal lamp state in the own car shows, under following two kinds of situation, still can not and confirm whether oneself should quicken to pass through the crossing excess time according to the color of current demand signal lamp:
1, the current red light that is shown as of belisha beacon; But the countdown demonstration is about to become green light, and the driver can not judge that can signal lamp become green light when vehicle arrives the crossing according to own current situation; Whether need Reduced Speed Now, stop when arriving the crossing then and wait for if promptly being not sure of oneself;
2, the current green light that is shown as of belisha beacon; But the countdown demonstration is about to become amber light; The driver can not judge according to own current situation; Whether signal lamp can become red light when vehicle arrives the crossing, and promptly the driver can not judge oneself whether can quicken rapidly through the crossing, to avoid unnecessary wait.
Summary of the invention
Technical matters to be solved by this invention provides and a kind ofly priority signal is provided and can points out the driver command and control center for bus priority signal to be provided for bus; Therefore the driver can make a response rapidly according to this information, determines it oneself is quicken through crossing or the preferential automatic control system of should ramp to stop waiting for of bus signals.
