Description
Technical field
The present invention relates to intelligent transportation field, particularly a kind of road traffic formula traffic guidance device of taking the initiative in offering a hand that is used for.
Background technology
Along with the development of society, the very big raising of people's living standard, the city traffic is faced with increasing problem.It shows the following aspects, and at first along with the quickening of socialization process, increasing people pours in the big city, has caused the wretched insufficiency of road capacity; Secondly growth in the living standard; The desire that people buy automobile is more and more stronger, and the continuous increase of automobile quantity causes the crowd who takes public transport to reduce gradually, the excessively rapid growth of personal car; To cause a lot of traffic problems,, environmental pollution congested and energy resource consumption etc. like traffic hazard, road.Therefore, entire society has higher requirement to safety, the convenience of communications and transportation, how on limited soil, rationally to build and the planning traffic route; How the reasonable disposition traffic signals are effectively induced traffic flow, reduce the generation of traffic hazard to greatest extent; Alleviate environmental pollution; Reducing energy resource consumption, improve and line efficiency, is the big problem of pendulum field of traffic relevant departments and personnel.
In order to solve above-mentioned a series of problem, China has obtained very big achievement.Comprise that mainly static road traffic is induced direction board, such as a crossroad, having direction board to indicate which bar road tells the driver to turn left be, turn right with arrow is that which bar road, the place ahead have information such as which bar road; Be exactly through the traffic guidance screen in addition, with red, yellow, green three kinds of colors obstruction, crowded, unimpeded three kinds of traffic state informations be provided respectively, induce the driver to select suitable circuit, avoid traffic congestion.
Being very easy to receive such environmental effects exactly for drawback of these static traffic direction boards, is exactly the influence of driver's oneself factor in addition.Such as when experiencing a thick fog weather or front when bus is arranged, the driver has little time to see clearly the sign that turns around, thereby misses the opportunity of turning around, and can only continue to move ahead to seek the next one and turn around ground.In the highway layout in city, two differ distant with turning around, and this has brought inconvenience to the driver undoubtedly, has reduced line efficiency, has increased energy resource consumption, has also increased this road section traffic volume flow.When also having the traffic marking when the careless roadside of driver, particularly association's only wholwe-hearted driving of driver of driving just dare not be seen the traffic marking on the roadside, and this must can make that also the driver walks more, reduces line efficiency.The screen of inducing for the reflection road net traffic state can provide the traffic behavior of the place ahead road network; But the information that provides is fairly simple; Any condition of road surface can only be used a kind of color showing in red, yellow, green; Therefore information is abundant inadequately, and stop up at three kinds of states, near crowded, the unimpeded intersection or interface point, which of two adjacent traffic behaviors very difficult judgement belong to.So the inducing action to traffic is limited.
