Description
Technical field
The invention belongs to road information technical field in road traffic system.
Background technology
Along with the development of national economy, the raising of people's income, the recoverable amount of city automobile is increasing, and the jammed problem of urban transportation is more and more serious.How to allow urban road is unimpeded has become the gerentocratic task of top priority of a lot of Chinese city, be also problem that citizen are comparatively deeply concerned and everyday faced by one of worry.Urban road crowded, the result that the density of population in the certain city of its basic reason and car density increase severely.To fundamentally address this problem and be not easy, neither the target of the application.But rationally using existing path resource efficiently, for road user provides accurate, quick and comprehensive real-time road condition information, is the crowded effective way of road of releiving at present; The road in city is just as a net, and the traffic congestion of the road in city has a very fearful phenomenon, and exactly when a certain section accident occurs and makes this section block up, queues of stationary traffic can promptly " growth ".Along with " growth " of queues of stationary traffic, section entrance has piled with automobile very soon, and these automobiles have also been blocked the automobile that will enter this section and other these crossings of process, make the road be connected with this section also occur very soon blocking.Vicious cycle like this, just there will be large-area blocking very soon.If other drivers can not be notified in time.A lot of automobile will continue the section driving towards these blockings.Time one road in long likely whole city becomes a large parking lot, and this is not shocking.Obviously this is the result that traffic information fails to transmit in time.In view of this, a lot of driver before travel wishes traffic conditions and the road conditions of first understanding each section adjacent in periphery, neutralization way, way, can get around jammed section, arrives destination smoothly with the shortest time.
Urban human drives a car to travel and also has another worried on urban road, and that is exactly that traffic lights are close especially, and often feels in a dilemma when crossing traffic light intersection.Why say so because, steering vehicle by traffic light intersection time, driver will faced by indefinite factor be a lot.In the face of these indefinite factors, the normal difficulty that judges between right and wrong of driver, or even do not know where to begin.I says so not is be complicated by asking, illustrate: traffic light intersection come by automobile three kinds of situations, one is when red, or amber light is bright, or green light.But the excess time of current cresset, automobile are to the concrete distance of traffic light intersection automobile stop line, with the speed of a motor vehicle feasible at present, and whether the remaining cresset time enough allows automobile by crossing etc., and these factors are all very difficult judgements; When driver is red light before different distance is seen, there is different ways.Time closely, yes ramp to stop, this is that everybody of affirmative can accomplish.But when driver finds when red in larger distance, the driver of different quality has different ways.Conservative steady driver yes release the gas pedal, allows car slip to traffic light intersection, and carries out the preparation of braking at any time, does not only safety but also fuel-efficient like this.But most of driver then takes distinct way.They are unwilling to wait for, have been used to wait a green light cycle because they taste, and all take turns less than oneself hereby taste by crossing.When they will strive for turning green light, can, rapidly by crossing or strive for coming forward position, be all to pass through traffic light intersection as early as possible.Do not slow down or accelerate to advance so he takes, the way of racing against time.Acceleration has certain risk, particularly because of red light, time car above can stop at any time, is easy to cause rear-end collision; As automobilist it is seen that amber light time, different drivers also has different ways, but relative to red light and green light, its danger is less, because its time is shorter; The third situation is green light.This is a most dangerous comparatively speaking cresset, and its reason is that nearly all driver has a kind of psychology to be exactly be reluctant to wait for, and though seen green light distance have want to take advantage of fast logical.Therefore, their major part all takes the action accelerated through.Consequently distance near the getting one's wishes realized in crossing.Distance crossing is far away, and result is that automobile just starts flicker close to green light before automobile stop line, and will transfer amber light at once.So radical people takes a risk to increase throttle further for racing against time.The driver had little time soon is with regard to emergency brake.A lot of traffic hazard often just occurs in this period.Accelerate the vehicle being easy to knock the clearance of other directions be forced through; Being easy to of emergency brake causes rear-end collision etc.So how, correctly could pass through traffic light intersection, how I, when driving is learned by driving school, when master worker and teaching material were never taught and driven over traffic light intersection, tackled the correct method of various situation.
In order to provide basis for estimation to driver by during traffic light intersection, people have found out in the other method of installing traffic lights inverse timing device of traffic lights.After having installed traffic lights countdown, the excess time of each cresset is very clear, and this measure seems to provide very large help for driver.But true also not as people is willing to, its installation does not only make the traffic hazard at this crossing decline, and makes its traffic hazard incidence rise on the contrary.Trace it to its cause in fact also very simple, racing against time, being reluctant to wait for is the mental habit of most driver, and particularly second, this hope was stronger when inverse soon.Although driver is aware of the traffic lights remaining time, the distance of the spacing traffic light intersection automobile stop line of oneself, owing to cannot accurately judge by the cause of viewpoint and direction restriction.Can the car of oneself during this period of time pass through crossing, and driver is now in the heart without assurance.So in fact the traffic light intersection having installed traffic lights inverse timing device makes driver puzzled.On the other hand whenever green light excess time only less than 10 seconds time, but a second behavior is robbed in the acceleration often causing some drivers, robbing second behavior main cause that occurs of accident often, is exactly that its order accident rate that the traffic light intersection of traffic lights inverse timing device is housed rises on the contrary.Therefore the green light crossing of traffic lights inverse timing device was much housed originally, and the requirement that traffic department should be popular eliminates traffic lights inverse timing device; One of maximum feature of urban highway traffic is exactly that traffic lights are many, crossing is many, some is local at a distance of just having two traffic lights less than 100 meters, these situations, more outstanding when driver comes a strange city, the stress that it makes driver drive considerably increases.
On the other hand at present the quantity of automobile gets more and more, restriction on traffic law and road surface is more and more tighter, and the stress that driver drives is increasing.Although road there is various traffic sign, but these traffic signs some blocked by trees, some has been contained in background, some then be have ignored by the driver of stress, cause driver in unclear situation beyond the Maximum speed limit in section, to have stopped car in the section that restricted stop, fall in the section that no turns first-class etc.The generation of these situations is all because driver does not know caused by the road conditions of current road segment.Traffic information mentioned here comprises various in excess time of each cresset of crossroads traffic light, current car position to the distance, section of traffic light intersection stop line forbidding and and information warning etc.
Be the information age of Construction Technologies in Twenty-one Century now, whose Information, who just wins initiative.Road traffic is no exception, if each automobile has a computer system, the real-time road condition information in all sections, the whole city can be stored, and point out road conditions that are current and periphery section by the form such as voice or text importing to driver, the so sure working pressure greatly alleviating driver, reduce the illegal number of times of driver, reduce the generation of traffic hazard.Regrettably, not such in currently available technology system.
Summary of the invention
Current and traffic information that is periphery section is obtained in order to help driver, this invention takes following measure: traffic light controller connects traffic monitoring command centre and/or radio road conditions information transmitting platform, traffic monitoring command centre connects radio road conditions information transmitting platform, electronic chart installed by the computer of automobile, and computer connects satellite positioning signal receiving trap and radio road conditions information receiver; Or traffic light controller connects traffic monitoring command centre and/or traffic monitoring command centre website, traffic monitoring command centre connects traffic monitoring command centre website, electronic chart installed by the computer of automobile, and computer connects satellite positioning signal receiving trap and wireless internet accessing device.
