Description

The undesirable small miniature road junction intelligent traffic bootstrap technique of lateral visual degree and system
Technical field：
The present invention relates to technical field of intelligent traffic management, specifically a kind of undesirable small miniature crossing intelligence of lateral visual degree Can traffic guiding method and system.
Background technology：
With the increasingly mainstreaming of the increasing and driving trip mode of car owning amount, traffic safety especially traffic intersection People's car is current, and security issues become increasingly urgent.At present, the current safety problem of people's car of big-and-middle-sized intersection, by intersecting The point duty guiding systems such as crossing installation traffic lights have obtained effective solution.But in the more numerous small miniature intersection of quantity Small miniature intersection inside crossing, including various all kinds of residential districts and office community, because each lateral road surface is generally deposited There are building, green plant etc. to block, causing the mutual visibility in lateral road surface relative to each other undesirable.So, small miniature friendship The people's car advanced simultaneously to crossing in each relatively lateral road surface particular safety distance range of cross road mouth, often the presence to other side with And predict deficiency to crossing direction travel information, when roll away from it is impermeable mutually find other side depending on shelter blind area when again because apart from too Closely it is difficult to take effective emergency measure in time, causes traffic accident often occurs in small miniature intersection.
Currently, in face of the undesirable small miniature intersection of this lateral visual degree, typically handed over using convex surface mirror device Logical guiding, but the defects of it there are three aspects and limitation, when convex mirror exist to lateral road surface and traveling people's car into As that can diminish than the original, it tends to be difficult to cause on road surface lateral toward each other into people's car in safe early warning distance range to other side Due regard, it is lateral toward each other second, when traveling people's car dysphotia, and when there are the harsh weather such as sleet haze People from road surface car can be reduced further to the notice of other people's car information imaging in convex mirror, third, especially, convex surface mirror device It is more effective to the early warning of unilateral people's car information（Such as the small micro- crossing situation of Fig. 2 typical case's Trident Type）But if having two and When lateral crossing is prompted because the undesirable needs of visibility enter pedestrian's car information early warning simultaneously above（Such as Fig. 1 typical case's cross type Small micro- crossing situation）, the applicability of convex surface mirror device will be greatly limited, the presence of these defects, greatly constrain convex Traffic guiding Function of the face mirror device in the undesirable small miniature intersection environment of lateral visual degree.
By installing stop-go command and guide system in the undesirable small miniature intersection of lateral visual degree, although Safe passing can be realized, but the system acquisition cost is high, expense burden can be significantly greatly increased, in addition, small miniature intersection Do not have too many people's car while current generally, install the system give red light waiting signal can greatly reduce on the contrary it is current Efficiency.
The content of the invention：
The purpose of the present invention is to overcome the shortcomings of above-mentioned prior art, and provides a kind of lateral visual degree undesirable small miniature crossing Intelligent transportation bootstrap technique.
It is a further object of the present invention to provide a kind of undesirable small miniature road junction intelligent traffic guiding system of lateral visual degree.
Present invention mainly solves the existing small miniature crossing mutual visibility in road surface lateral toward each other it is undesirable when, It is insufficient because being predicted each other other side's presence and travel information to crossing traveling people car simultaneously, and the traffic accident that may occur, together When overcome by install convex surface mirror device or installation stop-go command and guide system solve the defects of problem and limitation The problems such as.
The technical scheme is that：The undesirable small miniature road junction intelligent traffic bootstrap technique of lateral visual degree, its is special Part is, comprises the following steps：
A determines to need the not visible blind area that gives warning in advance, by lateral road surface be close to it is impermeable regard shelter on the basis of, from its face Risen to intersection end points to originally lateral road direction and intercept safe early warning distance m along roadside, divided with it among this lateral road surface The Projection Line Segment being correspondingly formed in boundary line, the rectangle surrounded or square areal extent, that is, be to determine what needs gave warning in advance Not visible blind area；
B installation intelligent transportation guiding systems, face trackside to what crossing crosspoint was advanced on each lateral road surface in small miniature intersection, Selection is beyond safe early warning distance m appropriate point position, integrated installation traffic guidance system, the spy of adjustment intelligent transportation guiding system Head, the not visible blind area for needing to give warning in advance can be detected；
C intelligent transportation guides, and the probe that can adjust investigative range will detect the information signal of people's car in the not visible blind area obtained, Transmit to the wireless messages transceiver that function is distinguished with channel and launched with specific channel；Function is distinguished with channel Wireless messages transceiver receive other not visible lateral people from road surface car information signals simultaneously, and instantaneous transmission is to being possessed text Word, voice and carry out the warning screen to alarm function, the warning of word splashette, phonetic warning and people Che Lai are sent to arrow from warning screen Splashette warns.
The undesirable small miniature road junction intelligent traffic guiding system of lateral visual degree of the present invention, it is characterized in that, by Probe, wireless messages transceiver, warning screen and solar panels integrated intelligent traffic guidance system, described solar panels lead to Cross power line respectively with probe, wireless messages transceiver, warning screen to be connected, there is provided kinetic energy needed for work；Probe passes through Signal transmssion line is connected with wireless messages transceiver, and wireless messages transceiver passes through signal transmssion line and warning screen It is connected.
Further, described probe can adjust investigative range.
Further, described wireless messages transceiver has channel to distinguish function, the wireless communication on different lateral road surfaces Breath launches the signal transmitting different from receiver imparting and signal receives channel.
Further, described warning screen possesses word, voice and come to alarm function.
The undesirable small miniature road junction intelligent traffic bootstrap technique of lateral visual degree of the present invention and system and existing skill Art is compared, and is had prominent substantive distinguishing features and marked improvement, can effectively be overcome existing convex surface mirror device in lateral visual degree Imaging in undesirable small miniature intersection traffic guiding, which diminishes, to be often difficult to cause two or more, due regard, lateral crossing The defects of applicability is not strong when individual, also can effectively it overcome red by being installed in the undesirable small miniature intersection of lateral visual degree High cost caused by green light point duty guiding system, it is inefficient the defects of, help to realize the lateral visual of various specified contexts Low cost, high efficiency, the universality of undesirable small miniature intersection traffic guiding are spent, final realize is felt at ease to pass through, led in order Row, safe passing.
