Electronic toll reduction transaction method and electronic toll collection system for renewable transaction

The present invention relates to an electronic toll reduction transaction method and an electronic toll collection system for preventing duplicate transactions.

In the traditional manual charging method, since the charging, the change or the sale, and the recovery of the ticket will consume a considerable amount of time, the toll booth area has always been the bottleneck of the expressway, and thus the overall speed of the expressway is reduced. In order to improve the above phenomenon, an electronic toll collection system using advanced communication and information technology has been developed.

One of the current electronic automatic charging methods is to use a specific short-range communication technology to use the microwave or wireless radio frequency tag to sense the deduction. It requires a passerby to install the device or the tag, and the sensing effect is easily affected by the external environment and is unstable. Another common electronic automatic charging method is to use image license plate recognition. This method does not need to install equipment or labels by passers-by. However, it also affects the recognition effect by factors such as camera position, light source, weather, and license plate fouling.

The above problems will affect the reliability of electronic automatic charging, resulting in failure of deduction. In the prior art, the deduction of the A and B sensing devices in the same position on the same driving path is successful, but the C-induction device between the two sensing devices fails to deduct the payment, and can only give up the deduction. However, since both the A and B induction devices have a record of successful deduction of the target vehicle, it can be reasonably determined that they should have passed the C-sensing device and should be deducted. How to restore and establish the deduction time of the C device is a subject to be considered.

In another embodiment, the step includes: acquiring, by the image acquiring device as the first data acquiring device, the license plate image data of the target vehicle passing through the first position within one hour of the predetermined time interval, thereby identifying the target vehicle through The first trading position of the first position.

In a preferred embodiment, the target vehicle may belong to one of the aforementioned plurality of vehicles. In this case, the target first trading time belongs to one of the plural first trading hours. In other words, when the first data acquisition device of step 1010 acquires the plurality of first transaction times of the plurality of vehicles passing the first position within the predetermined time interval, the first data acquisition device of step 1060 acquires the target vehicle within the predetermined time interval. The first trading time through the target of the first position is also completed simultaneously. However, in various embodiments, the target vehicle does not belong to one of the aforementioned plurality of vehicles.

Step 1070: The server calculates the expected transaction time interval according to the target first transaction time, the arrival time required, and the expected error time. More specifically, the step includes adding and subtracting the expected error time from the sum of the target first transaction time and the required time to calculate the front-end time of the expected arrival time interval.

As shown in FIG. 2, in an embodiment, the foregoing step 1042 further includes dividing the average speed of each vehicle in the plurality of vehicles between the first position and the second position into a plurality of groups according to the size, and according to each group by the server. The average speed included includes multiple sets of corresponding inter-station speeds; step 1050 further includes calculating, by the server, the plurality of sets of arrival time times according to the plurality of sets of inter-station speeds and inter-station distances; step 1070 further includes determining, by the server, A plurality of sets of expected trading time intervals are calculated for a trading time, a plurality of sets of required time, and a plurality of sets of expected error times; and step 1090 further includes comparing, by the server, the target second trading time and the plurality of sets of expected trading time intervals, when the target is The second trading time is located in one of the plurality of expected trading time intervals, and the target vehicle is determined to form an effective travel time between the first position and the second position; step 1100 further includes when the target vehicle forms an effective travel time, according to the target first trading time , the target second trading time, and the inter-station distance calculate the speed between the target stations, according to the closest of the multiple sets of inter-station speeds Inter-station's velocity information acquiring means and a first and a third material between the second data acquisition means acquires first data acquiring means with respect to the distance means calculates the reduction target vehicle transactions. In different embodiments, the target may be calculated according to the distance between the target station and the distance between the third data acquisition device located between the first data acquisition device and the second data acquisition device and the first data acquisition device. The restoration transaction time of the vehicle.

Further, there may be different speed groups in the same road section. For example, in the vicinity of the interchange, the common side is the slowest because the vehicle is lined up under the interchange, the middle lane is affected by the speed, and the inner lane is less affected. The speed is faster. Through the above steps, multiple sets of expected trading time intervals can be distinguished, as long as the target second trading time is located in one of the plurality of sets of expected trading time intervals, that is, the target vehicle is determined to form an effective travel time between the first position and the second position. And to calculate the restoration transaction time of the target vehicle. In this way, the calculated reduction transaction time can be made closer to the average situation and more reasonable.
