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 affects people's living standard.In order to alleviate traffic congestion, meet people's trip requirements, public transit vehicle is implemented to signal priority and control, at home and abroad generally used.
Summary of the invention
Existing Chinese patent literature 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 forms by being arranged on the modules such as GPS on quick public transport vehicle and MCU, RF wireless transmission, crosses RF wireless transport module by the vehicle location information exchange of the bus rapid transit of acquisition and in real time, is automatically sent data to ground reception and treating apparatus and carried out the processing that wireless data avoids conflict by the RF wireless transport module of car-mounted device.Ground receiving and processing device is processed the related data information of the quick public transport vehicle of acquisition and 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 these information in real time, are automatically sent to traffic signal controlling machine, by traffic signal controlling machine, the traffic lights at crossing are carried out in time, effectively switched again, be preferably quick public transport vehicle and give way, thereby guarantee that quick public transport vehicle is preferential, fast passing.Adopt above-mentioned technology, there is following problem: when the driver of BRT vehicle drives to crossing, can not judge that ground receives and treating apparatus whether treated the override requests of oneself, if current demand signal is green light signals, and will become red light, driver does not know whether traffic signal controlling machine can keep green light for oneself at once; If current, be red light phase, driver can not determine traffic signal controlling machine for allow oneself preferentially by and rapidly signal lamp is set to green light; Therefore in above two kinds of situations, when driver drives to crossing, can not determine it oneself is slow down to wait for or accelerate and pass through, in comparatively passive state.
Existing Chinese patent literature CN 101334934 A disclose a kind of vehicle mounted traffic displaying apparatus, this device is for being arranged on the traffic signal indicator of the indication of one in car junction ahead signal, described indicating device comprises, a display panel, the signal receiving device being connected with display panel.On described display panel, also there are the loudspeaker of a sounding.During use, this device is accepted the data of the traffic lights of junction ahead, and shows on display panel, if junction ahead is red light, on display panel, shows that junction ahead is red light, and shows counting down of red light, if instead be that green light is also like this.Adopt the vehicle mounted traffic displaying apparatus in technique scheme, although can show the state of junction ahead signal lamp, but for driver, when vehicle arrives crossing, the demonstration of no matter seeing the signal lamp of junction ahead still sees that the signal lamp state in own car shows, in following two kinds of situations or can not and determine according to the color of current demand signal lamp whether oneself should accelerate to pass through crossing excess time:
1, the current red light that is shown as of belisha beacon, but countdown demonstration is about to become green light, driver can not be according to own current situation judgement, and when vehicle arrives crossing, can signal lamp become green light, can not determine whether oneself needs Reduced Speed Now, parking waiting while then arriving crossing;
2, the current green light that is shown as of belisha beacon, but countdown demonstration is about to become amber light, driver can not be according to own current situation judgement, when vehicle arrives crossing, whether signal lamp can become red light, be that driver can not judge oneself whether can accelerate rapidly by crossing, to avoid unnecessary wait.
Summary of the invention
Technical matters to be solved by this invention is to provide and a kind ofly priority signal is provided and can points out driver command and control center for bus provides priority signal for bus, therefore driver can make a response rapidly according to this information, determines it oneself is accelerate by crossing or the preferential automatic control system of bus signals of should ramp to stop waiting for.
