Survey method.
Background technology
In recent years, China's highway flourished, and shortened the haulage time between city, while the institute of motor vehicles
The amount of having is sharply increased, and so as to cause vehicle accident more and more fiery, due to overspeed of vehicle or fails to reach highway minimum speed
The vehicle accident for requiring and causing can be found everywhere, and causes unnecessary life security and property loss, also gives traffic administration band
Pressure necessarily and burden are come.
With the development of technology of Internet of things, many intelligent transit equipments have been applied to point duty control field, have given
The conevying efficiency of traffic brings very big raising, and transport order is in good order；But also there is lucky, open anti-method in some lawless persons,
Driving is galloped on a highway；Some unskilled drivers open high speed, it is believed that it is the safe driving first element that speed is low,
But the normally travel of other vehicles is affected, these all hide some dangers for vehicle accident.On a highway, drive over the speed limit is traffic
The principal element of accident, during high vehicle speeds, runs into obstacle and has little time to process；The wayward vehicle of driver, especially exists
The vile weathers such as sleet；Similarly for the vehicle for running at a low speed, the barrier being equal to before normally travel vehicle is the same, comes not
And dodge, will also result in the serious vehicle accident such as knock into the back.Therefore tighten traffic management, carry out to hypervelocity and slow moving vehicle
Looked over one's shoulder, be the effective means for reducing vehicle accident, it is ensured that the straightway only way of freeway traffic.
