Problems solved by technology
At present, in view of the high incidence of pedestrian crossing accidents and the high degree of danger without credit control, some intelligent street crossing facilities have emerged as the times require, but most of them use one-way behavior control, and few are designed from the perspective of both pedestrians and drivers; and at night or suddenly When an accident (vehicle out of control) occurs, the risk is high, and the safety improvement effect is not significant. The feedback of people and vehicle information is lagging, and it is difficult for pedestrians and drivers to obtain accurate and real-time traffic information. The people-oriented traffic concept has not be effectively reflected

Embodiment Construction
[0018] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.
[0019] Such as figure 1 As shown, a multi-dimensional hierarchical intelligent street crossing early warning system described in the present invention includes a risk level evaluation system for untrusted street crossing sections, an information detection system, an information evaluation system and an information early warning system.
[0020] More specifically, the risk level evaluation system for untrusted crossing sections uses neural network algorithms to classify different roads, and selects 12 roads from four aspects: traffic composition, road conditions, traffic facilities, and the temporal and spatial distribution of traffic flow. Factors that affect pedestrian crossing safety are used as evaluation indicators, and the weight is determined by the AHP. Finally, the risk level evaluation model of the untrusted crossing section ...

The invention relates to the field of traffic safety of pedestrian crossing in the middle section of a suburb non-signal-control road, in particular to a multi-dimensional grading intelligent street-crossing early warning system which comprises a non-signal-control street-crossing road section danger level evaluation system, an information detection system, an information evaluation system and aninformation early warning system. Effects of system bidirectional early warning, real-time feedback of road section information and reduction of accident rate are achieved through real-time acquisition of road section crossing pedestrian and vehicle information. The purposes of providing multi-dimensional early warning information and optimizing a driving sight distance visual area are achieved bymeans of scientific arrangement of corresponding early warning facilities in the system, and thus the street crossing safety of a non-signal-control road section is effectively improved.
Description
technical field [0001] The invention relates to the field of traffic safety for pedestrians crossing the middle section of a non-signature-controlled road in the suburbs, in particular to a multi-dimensional and graded intelligent street crossing early warning system. Background technique [0002] Untrusted pedestrian crossings in cities often have problems such as mixed pedestrians and motor vehicles, unclear allocation of road rights, etc., so it has always been a road section with a high incidence of accidents. At present, in view of the high incidence of pedestrian crossing accidents and the high degree of danger without credit control, some intelligent street crossing facilities have emerged as the times require, but most of them use one-way behavior control, and few are designed from the perspective of both pedestrians and drivers; and at night or suddenly When an accident (vehicle out of control) occurs, the risk is high, and the safety improvement effect is not signi...
