Highway Linear Induction Flag Is Set To Study

In order to ensure the road traffic safety and unobstructed, the road traffic sign has been extensively used on modern highway. The road traffic sign has static behavior and dynamic difference according to the states of information transmitted. Static traffic sign has been mainly used now on the Chinese highway (including the express way). As a kind of important safety devices of the traffic system of modern road, static traffic sign (are abbreviated as the traffic sign , same below )'s function is transmit information to the road traffic user (including the driver , passenger , pedestrian) through loading a group of particular information (i.e. a group of particular figure , symbol or characters)in marking the face in advance, so that to ensure the vehicle security and unobstructed. According to the practice result of the road traffic safety, to make the traffic sign transmit information to the driver effectively and reliably, the design of the traffic sign must be scientific, besides, disposing rationally along the line of the road of traffic sign is also very important. Since the driving speed is high, the traffic flow is large in highway, the traffic sign established science or not is directly influencing the traffic safety of the road. According to the investigation: the traffic sign set up improper is close connected to high traffic accident incidence on Chinese expressway Because lack the essential theoretical direction to the science of the traffic sign's design, the establishment of the Chinese expressway traffic sign has the problem that some can't ignore at present, forming potential impact to the traffic safety of the expressway.Firstly, we study the position of the curved way induce the sign, then proposed a kind of artificial algorithm to establishment traffic sign rationally, by extracts the design data of the road and reference the highway design specification and relevant formula, this method can help us to insure the concrete position accuracy of the traffic sign of bad line shape highway, this has not only overcome the phenomenon that set up sign mainly relied on experience in the past, but also can help driver appraising the advantage and shortage of the position of sign by simulator directly, so that to let the position of sign reasonable bychange it.
