ETC is the electronic toll collection system of not stopping, ETC specialized lane is for those vehicles that have installed ETC vehicle-mounted device to use, adopt the electronic toll collection mode, ETC electronic toll collection system is the most advanced way bridge toll collection mode in the world at present, through the special short-range communication of microwave between the microwave antenna on the vehicle-mounted electronic label installed on vehicle windshield and the ETC lane on the toll station, utilize computer networking technology and bank to carry out the backstage settlement and process, thus reach the vehicle and pass the purpose that the bridge toll station need not stop and can pay for the way bridge fee through the way bridge, the electronic toll collection technology is suitable for adopting under the highway or the busy bridge tunnel environment especially. The electronic toll collection system under the traditional lane isolation measure is generally called a single-lane electronic toll collection system, and the electronic toll collection system under the free traffic flow under the condition of no lane isolation is generally called a free flow electronic toll collection system. The electronic toll collection is implemented, and vehicles can be allowed to pass at high speed, so that the traffic capacity of a road can be greatly improved; the highway charging is electronic, the cost of charging management can be reduced, and the operating benefit of vehicles can be improved; and simultaneously, the noise level and the exhaust emission of the toll gate can be greatly reduced. The traffic capacity is greatly improved, so that the scale of the toll station can be reduced, and the capital construction cost and the management cost are saved.
Because the ETC recognition mode is a front induction coil, when a vehicle runs to the induction coil, a front railing is opened, the interval is about ten meters, some non-ETC users exist on an ETC lane, the vehicle wants to rub the card while the gap passes, although counter measures such as black list drawing exist at high speed, some vehicles still hold a good feeling, the vehicle accelerator and opportunity are mastered by the vehicle users, some vehicles successfully pass and some vehicles rub against each other, and due to the fact that the accident probability of the behavior is high, traffic resources and police resources are greatly wasted after alarm processing, the ETC lane is not paid back when the vehicle runs, even if the accident does not occur, the mood of a rear vehicle driver is greatly influenced, and the accident risk probability of the road section is increased invisibly.

Specifically, the surface of the supporting roller 7 is provided with a rubber layer, and the highest point of the supporting roller 7 protrudes 20-30mm out of the road surface.
Through the arrangement, the wear resistance of the supporting roller 7 and the friction force of contact between the supporting roller 7 and the tire can be increased, the contact capability between the supporting roller 7 and the tire can be improved by the convex supporting roller, and the performance is better in the accuracy of reaction speed and the controllability of low speed.
The working principle is as follows: when a vehicle wants to drive into an ETC channel, firstly the vehicle passes through the recognition coil 105, the recognition coil 105 recognizes an ETC device installed on the vehicle and reads information, then the vehicle slowly drives from the linear speed limit area 3, the speed limit unit 2 in the linear speed limit area 3 provides enough friction when the vehicle slowly passes through, so that the vehicle can normally drive, when the vehicle drives to the charging coil 104, the fee deduction is calculated in the background until the vehicle drives to the railing coil 102, the railing 103 is lifted, the vehicle smoothly passes through, if the vehicle waits in the linear speed limit area 3, the vehicle is mechanically driven, when a truck reaches the recognition coil 105, the speed of the truck is larger than or equal to the vehicle idling beside the lane, if the vehicle beside needs to be accelerated and changed lane, and when the truck suddenly accelerates, the friction between the truck and the speed limit unit 2 is suddenly reduced, so that the wheels idle, therefore, the vehicle can be stationary, the lane change cannot be finished without acceleration, the vehicle can only run forwards continuously and is paid by manpower, so that a driver can be forced to avoid the behavior of card smearing mentally and cannot rub the card successfully, the benefit of an ETC vehicle is effectively ensured, the vehicle can keep the vehicle distance in a linear speed-limiting area 3, the driving of a small wing is facilitated, the road order is maintained, the distance between the set roller sets is small, when the tire passes through the speed-limiting unit 2, the tire is contacted with three roller sets inevitably, particularly the supporting roller 7, when the tire runs, certain friction force and relative rotation are generated on the supporting roller 7, the damping force during rotation is provided through the damping box 6, the direction of the supporting roller 7 can be changed by utilizing the roller 5, namely when the tire turns, the supporting roller 7 can rotate along with the rotating, and the relative friction force in the circumferential direction of the supporting roller 7 is ensured, when the tire runs between the two rows of support rollers 7 in one speed limiting unit 2, the tire is in contact with only the support rollers 7, when the tire runs at a slow speed, the support roller 7 rotates at a slow speed, and the support roller 7 rotates to drive the support rotating shaft 62 to rotate, thereby transmitting with the damping box 6 through the reduction gear set 61 to generate a damping effect, and when the supporting roller 7 rotates at a high speed, the locking member 71 is out of contact with the supporting rotation shaft 62 by the centrifugal force, that is, the support roller 7 directly rotates through the bearing 72 and the support shaft 62, that is, the support roller 7 is in an idle state and cannot provide friction force to the tire, the tire is idle between the two support rollers 7 and cannot advance, thereby achieving limitation of the vehicle speed, the limitation on the sudden acceleration start is very effective, thus achieving speed isolation and preventing the acceleration lane change condition from occurring.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
