Technical Field

The utility model relates to a traffic safety equipment technical field, concretely relates to traffic accident anticollision early warning intelligence traffic lights.

Background

Crossroad traffic accidents are common, various warning measures such as traffic lights, marked lines, camera shooting and the like are usually difficult to avoid, the main reason is that most of the inherent non-direct lanes of the crossroad are outside the sight of a driver, the observation and judgment of targets outside the sight and in a distance are critical to driving safety, the sudden appearance of the targets outside the sight easily causes judgment and misoperation, and if the targets are not absorbed in driving, the traffic accidents are easy to happen.

Although the use of the existing traffic lights can reduce congestion to a certain extent and provide certain guarantee for traffic safety, the disadvantages are obvious, and the main reasons are that the warning effect of the existing traffic lights is limited, road traffic can be guided only according to set time, detection and identification of intersection traffic flow cannot be realized, discrimination of abnormal targets outside the sight line of the intersection cannot be realized, and early warning cannot be given to suspicious targets which are likely to cause traffic accidents in advance, so that intersection traffic accidents are difficult to avoid, casualties and property loss are caused, and the traffic accidents are painful for a long time.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a traffic accident anticollision early warning intelligence traffic lights for solve at least one above-mentioned problem that exists among the prior art.
