Description

Road code and road conditions driving assisting system

Technical field

The invention belongs to a technical field of road traffic system.

Background technology

Along with the growth of urban population density, city, prohibit and rub and the increase of automobile pollution, the road in city is more and more jammed.Traffic congestion has become one of maximum worry that a lot of urban humans face everyday.Therefore, before travel each driver wishes that the traffic conditions of first understanding periphery, neutralizing each section adjacent in way is on the way road conditions.To can get around jammed section, smooth in destination with the shortest time; Urban human drives a car to travel and on urban road, also has another worry, and that is exactly that traffic lights are close especially.Why say so, because when steering vehicle passes through traffic light intersection, the indefinite factor that driver will face is a lot.In the face of these indefinite factors, driver's the normal difficulty that judges between right and wrong, or even do not know where to begin.I say so not is to be complicated by asking, for example: automobile is come traffic light intersection three kinds of situations, the one, when red, or amber light is bright, or green light.But the excess time of current cresset, automobile be to the concrete distance of traffic light intersection automobile stop line, with the feasible speed of a motor vehicle at present, whether the remaining cresset time enough allows automobile by crossing etc., and these factors are all very difficult judgements; When driver sees above red light in different distance, there is different ways.In the time of closely, yes ramp to stop, this is that sure everybody can accomplish.But when driver is when larger distance is found when red, 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 at any time the preparation of braking, does so not only safety but also fuel-efficient.But most of drivers have taked distinct way.They are unwilling to wait for, because they taste, have been used to wait a green light cycle, all take turns less than oneself by the hereby taste at crossing.When they will strive for turning green light, can be rapidly by crossing or strive for coming forward position, be all in order to pass through as early as possible traffic light intersection.So he has taked not slow down or accelerate to advance, the way of racing against time.Acceleration has certain risk, particularly because of red light, when car above can stop at any time; When automobilist see be amber light time, different drivers also has different ways, but with respect to red light and green light, its danger is less; The third situation is green light.This is a most dangerous comparatively speaking cresset, and its reason is that it is exactly to be reluctant to wait for that nearly all driver has a kind of psychology, has and wants to take advantage of fast leading to apart from distance no matter seen green light.Therefore their major part has all been taked the action that acceleration is passed through.Consequently apart near the getting one's wishes realized in crossing.Far away apart from crossing, result is that before automobile approaches automobile stop line, green light just starts flicker, and will transfer amber light at once.So radical people takes a risk to have strengthened throttle for racing against time.The driver who has little time is soon with regard to emergency brake.A lot of traffic hazards often just occur in this period.That accelerates to pass through by force is easy to knock the vehicle that other directions are let pass, emergency brake be easy to cause rear-end collision etc.So how, could correctly pass through traffic light intersection, when I learn driving in driving school, master worker and teaching material were never taught while driving over traffic light intersection, how to tackle the correct method of various situations.

For being provided during by traffic light intersection to driver, basis for estimation, people found out in the other method that traffic lights inverse timing device is installed of traffic lights.Installed after 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 on the contrary its traffic hazard incidence increase.Trace it to its cause in fact also very simple, racing against time, be reluctant to wait for is most driver's mental habit, and particularly second, this hope was stronger when inverse soon.Although driver has known the remaining time of traffic lights, the distance of the spacing traffic lights of oneself, because the cause of viewpoint and direction cannot accurately judge.Can the car of oneself during this period of time pass through crossing, and driver is now in the heart without holding.So being installed, the traffic light intersection of traffic lights inverse timing devices in fact make driver puzzled.On the other hand whenever green light excess time is during only less than 10 seconds, but often cause some drivers' acceleration and rob a second behavior, robbing second behavior main cause that accident occurs often, is exactly that its makes the accident rate of the traffic light intersection that traffic lights inverse timing device is housed rise on the contrary.The green light crossing of therefore much traffic lights inverse timing device being housed originally, traffic department should popular requirement cancel traffic lights inverse timing device.One of maximum feature of urban highway traffic is exactly that traffic lights are many, crossing is many, and some is local at a distance of just having two traffic lights less than 100 meters.

The at present restriction on more and more, the traffic law of the quantity of automobile and road surface is more and more tighter, and the stress that driver drives is increasing.Although there are various traffic signs on road, but these traffic signs some by trees block, some has been contained in background, some has been ignored by nervous driver, caused driver in unclear situation, to exceed the Maximum speed limit in section, in the section that restricted stop, stopped car, in the section that no turns, fallen first-class.The generation of these situations is all because due to the road conditions in the unclear current section of driver.If have a device on each car, current and the periphery of the form prompting that can show by voice or word is the road conditions in all sections, the whole city even, the so sure generation that greatly alleviates driver's pressure, the illegal number of times that reduces driver and minimizing traffic hazard, can make driver get around jammed section simultaneously, avoid these sections further jammed, make citywide traffic more smoothly, and driver can arrive destination as early as possible.Regrettably, in currently available technology, do not have such device.

Summary of the invention

For helping driver to understand instant road conditions current, all sections of periphery or even the whole city, assist driver driving vehicle, the present invention has taked following measure: traffic monitoring command centre connects traffic monitoring command centre website, on road, mark road code, road code reading device and wireless internet accessing device are installed, automobile computer connection speed sensor, wireless internet accessing device, road code reading device and installation electronic chart on automobile; Or traffic monitoring command centre connects radio road conditions information transmitting platform, on road, mark road code, road code reading device and radio road conditions information receiver are installed, automobile computer connection speed sensor, radio road conditions information receiver, road code reading device and installation electronic chart on automobile.

The benefit of doing is like this to utilize internet and large, the removable transmission of radio road conditions information transmitting platform coverage, invest the feature such as little and propagate traffic information; By giving each section of road establishment road code, road code reading device is installed on automobile, make automobile on the road of these codes of leading the way through out-of-date, Neng Yong road code reading device reads the road code in current section, makes in car the computer current section of identification automatically.Then by computer, search and show traffic information current and periphery section.The automobile stretch of often passing by, computer will upgrade a traffic information according to road code, make driver can support in time the road surface situation of holding; The real-time road condition information of each road of incity, city, can be sent to each automobile immediately by traffic monitoring command centre website or radio road conditions information transmitting platform.Make each driver can grasp in time the traffic information of current section, all roads in periphery section or even bed rearrangement city, for driver's safe and efficient driving is offered help.
