Brief description of the drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
The utility model is described in further details below in conjunction with the accompanying drawings.
Referring to Fig. 1, the utility model includes dual radars microwave traffic detector, model：Tractech T-11；Vehicle-mounted intelligence
Energy terminal, model：V600；Wifi signal projectors, model：FAST FW150US；Wifi signal receivers, model：TL-
WN726N；Control work station, model HP Z238W2Z90PA；Variable electronic advices plate, model：P10MM.Traffic detector is used for
Real-time collecting traffic flow information, and collected transport information is passed through into wifi network using the first wifi signal projectors
It is transferred to control work station.Vehicle intelligent terminal is used to carry out the emergency such as alarm such as traffic accident, vehicle trouble；Work as generation
During emergency, vehicle location and accident alarming information are transferred to control work station by vehicle intelligent terminal by wifi network,
Wherein whether accident alarming information includes knocking into the back, scratch and having some casualties, can be according to circumstances in vehicle intelligent terminal
On the option that sets selected.Work station is controlled to be received by the first wifi signal receivers by traffic detector and vehicle-mounted
The information that intelligent terminal is sent, and contrasted with setting value, judge to limit corresponding to present road state in which and the state
Speed value.Control work station that speed limit is sent into present road by the 2nd wifi signal projectors after speed limit is calculated

Show.
The utility model main course of work and principle：
The utility model sets wagon detector on through street, collects the Real-Time Traffic Volume letter on section to be controlled
Breath, spacing distance of the Adjacent vehicles detector on road are 1 kilometer, and detection in every 30 seconds is once；Wagon detector will detect
Traffic flow information control work station is transferred to by wifi network.Driving vehicle is respectively mounted vehicle intelligent end on through street
End, when traffic accident, the emergency such as vehicle trouble occur for some vehicle, vehicle intelligent terminal is by the accident class of Current vehicle
Type and vehicle position information are transferred to control work station by wifi network.Work station is controlled according to the information being collected into, with setting
Definite value is contrasted, for example magnitude of traffic flow setting value can be divided into three class, is idle (0-1000/hour/car of flow respectively
Road), normal (1000-2000/hour/track of flow), congestion (2000-2500/hour/track of flow)；Emergency
Major accident and minor accident/vehicle trouble can be divided into, for example major accident is that more cars occur to bump against and casualties occur, gently
Micro- accident is that occur knocking into the back, scratch and without casualty situations etc., can according to circumstances carry out the setting of different options；Vehicle location can
It is divided into current road segment and downstream road section.For example when traffic behavior is idle, speed limit can be corresponding to no emergency
120 kilometers are per hour, emergency be major accident and in speed limit corresponding to current road segment can be 70 kilometers per hour,
Emergency be major accident and in speed limit corresponding to downstream road section can be 80 kilometers per hour, emergency is slight
Accident/vehicle trouble and can be 80 kilometers in speed limit corresponding to current road segment, emergency be minor accident/vehicle therefore
It can be 90 kilometers to hinder and be in speed limit corresponding to next section.When traffic behavior is normal, corresponding to no emergency
Speed limit can be 100 kilometers per hour, emergency is major accident and in speed limit corresponding to current road segment can be
50 kilometers are per hour, emergency be major accident and in speed limit corresponding to downstream road section can be 60 kilometers per hour,
Emergency is minor accident/vehicle trouble and can be 60 kilometers in speed limit corresponding to current road segment, and emergency is
Minor accident/vehicle trouble and in speed limit corresponding to next section can be 70 kilometers.When traffic behavior is congestion, nothing
Speed limit corresponding to emergency can be 80 kilometers per hour, emergency is major accident and corresponding to the current road segment
Speed limit can be 40 kilometers per hour, emergency be major accident and in speed limit corresponding to downstream road section can be 50
Per hour, emergency is minor accident/vehicle trouble and can be 50 kilometers in speed limit corresponding to current road segment kilometer,
Emergency is minor accident/vehicle trouble and can be 60 kilometers in speed limit corresponding to next section.Finally by upper
Variable electronic advices plate on one section of road and present road is shown；After completing a cycle detection of 30 seconds, variable limit
The magnitude of traffic flow and emergency information in speed system automatic detection next cycle, repeat the above steps, it is determined whether need to adjust
Whole current city through street speed limit.
The utility model can be prompted effectively, reduce the traffic jam triggered by traffic accident and secondary collision.This
Each setting value can be according to circumstances adjusted in utility model.
