Electronic toll repeat transaction determination method and electronic toll collection system for determining repeated transactions

The present invention relates to an electronic toll repeat transaction determination method and an electronic toll collection system for determining 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. In addition to the failure of sensing deduction, repeated deductions are also a problem that is valued. In the prior art, when judging whether or not to repeat the transaction, based on the record of the target vehicle itself, it is simple to compare whether the target vehicle has multiple transaction records in a specific time interval, but the traffic condition and other factors may affect the speed. The impact may lead to misjudgment and room for improvement.

The electronic toll repeat transaction determination method and the electronic toll collection system for determining duplicate transactions of the present invention are preferably used in an electronic toll road system.

As shown in the preferred embodiment of FIG. 1, the electronic toll repeat transaction determination method of the present invention includes, for example, the following steps.

Step 1010: The first data acquisition device acquires a plurality of first transaction times when the plurality of vehicles pass the first location within a predetermined time interval. The first data acquisition device includes a wireless radio frequency sensing device, an infrared sensing device, an image capturing device, and the like, and the predetermined time interval can be arbitrarily specified according to requirements, for example, 1 hour. The first location can be any location on the highway that is arbitrarily specified, such as between two lanes. For example, the step includes: sensing, by the wireless radio frequency sensing device as the first data acquiring device, the radio frequency tag data of the plurality of vehicles passing through the first location within one hour of the predetermined time interval, thereby obtaining the plurality of vehicles passing through the first location. The first trading time. 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 plurality of vehicles passing through the first position within one hour of the predetermined time interval, thereby identifying and obtaining the plurality of vehicles passing through The first trading time of the first position.

Step 1020: The second data acquisition device acquires a plurality of second transaction times of the plurality of vehicles passing through the second location, wherein the first location and the second location have an inter-station distance. The second data acquisition device includes a wireless radio frequency sensing device, an infrared sensing device, an image capturing device, and the like. The second location can be any location that is arbitrarily specified on the highway, such as between two interchanges. The first position and the second position are preferably, but not limited to, different positions located on the same highway, and pass through the first position and then through the second position in the direction of the vehicle. For example, the step includes the wireless radio frequency sensing device as the second data acquiring device, and the wireless radio frequency tag is sensed at the second position by the plurality of vehicles passing through the first position within one hour in the predetermined time interval in the previous step. The data, in turn, obtains the second trading time of its plural through the second position. In another embodiment, the step includes acquiring, by the image acquisition device as the first data acquisition device, the plurality of vehicles passing through the first location within one hour of the predetermined time interval in the previous step, and acquiring the second location at the second location. The license plate image data is further identified to obtain a plurality of second trading hours of the plurality of vehicles passing through the second location.

Step 1030, the server receives the plural first transaction time and the second number transaction hour. Specifically, the server may receive the first first transaction time and the second number obtained by the first data acquisition device and the second data acquisition device respectively by a data carrier (eg, a memory card) transfer, a cable wired connection, or a wireless communication manner. transaction hour.

In step 1040, the inter-station speed is calculated by the server according to the first transaction time, the second transaction time, and the inter-station distance. In a preferred embodiment, step 1040 includes: Step 1041, calculating, by the server, between each of the first location and the second location of each of the plurality of vehicles based on the first transaction time, the second transaction time, and the inter-station distance The average speed; and step 1042, the inter-station speed is calculated by the server based on an average speed between the first position and the second position of each of the plurality of vehicles. More specifically, the average speed between the first position and the second position of the plurality of vehicles is further averaged by the calculation of the server to obtain the inter-station speed.

In step 1050, the server calculates the time required for arrival based on the inter-station speed and the inter-station distance. More specifically, it is the calculation of the server that divides the inter-station distance by the inter-station speed to obtain the time required for arrival.

Step 1060: The first data acquisition device acquires a target first transaction time for the target vehicle to pass the first location within a predetermined time interval. For example, the step includes: receiving, by the wireless radio frequency sensing device as the first data acquiring device, the radio frequency tag data of the target vehicle passing through the first location within one hour of the predetermined time interval, thereby obtaining the target vehicle passing the first position. Target first trading time. 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.

Step 1080: The second data acquisition device acquires the target second transaction time of the target vehicle through the second location. For example, the step includes: sensing, by the wireless radio frequency sensing device as the second data acquiring device, the radio frequency tag data of the target vehicle passing through the second location, thereby obtaining the target second transaction time of the target vehicle through the second location. In another embodiment, the step includes: acquiring, by the image acquiring device as the second data acquiring device, the license plate image data of the target vehicle passing through the second location, thereby identifying the target vehicle to pass the second position of the target second. transaction hour.

Step 1090: The server compares the target second transaction time and the expected transaction time interval, and when the target second transaction time is within the expected transaction time interval, determining that the target vehicle forms an effective travel time between the first location and the second location.

Step 1100: When the target vehicle forms a valid travel time, and the first data acquisition device or the second data acquisition device acquires the target third transaction time of the target vehicle, and the target third transaction time is between the target first transaction time and the target number Between the two trading hours, the server determines that the target third trading time is the repeat trading time.

Further, the conventional electronic charging method determines whether or not to repeat the transaction, based on the recorded record of the target vehicle itself, and simply compares whether the target vehicle has multiple transaction records within a specific time interval, but the traffic flow condition, etc. Factors can affect the speed of the car and can lead to misjudgments. Take the two locations A and B with the data acquisition device and the communication channel between them. When there is a serious traffic jam between A and B, the target vehicle may stay close to the B position for more than a preset time interval, for example, 30 minutes. At this time, if there are more than two transaction records, the time record alone will be difficult to distinguish whether a duplicate transaction occurs or the target vehicle leaves the highway and then re-enters the highway and passes the B position. In contrast, in the electronic toll repeat transaction determination method of the present invention, since the calculation basis of the expected transaction time interval is based on a plurality of vehicles passing through the first position and the second position within a predetermined time interval instead of only the target vehicle itself, common sense The speed of the vehicle on the same section of the same time zone should not be too different, so whether the second trading time of the target can be used It is determined within the expected trading time interval whether the target vehicle forms an effective travel time between the first location and the second location. Then, whether the target vehicle forms an effective travel time between the first location and the second location as a screening criterion, further confirming that the first data acquisition device or the second data acquisition device acquires the target vehicle for the vehicle having the valid travel time The third trading time of the target determines that the third trading time of the target is the repeated trading time, that is, it is determined that a repeated transaction occurs. Thereby, it is possible to effectively prevent electronic tolls from being repeated. In the above example, the case where the target vehicle leaves the expressway and passes the expressway and passes the B position is not judged to be a repeat transaction because it does not belong to the case of forming a valid travel time.

In an embodiment, the expected error time comprises obtaining the step of: calculating, by the server, the time required for each vehicle in the plurality of vehicles from the first position to the second position according to the first transaction time and the second transaction time; The server calculates the standard deviation as the standard deviation time according to the time required for each vehicle in the plurality of vehicles from the position to the two positions; and the server multiplies the standard deviation time by N as the expected error time, where N is an integer . N is preferably equal to plus or minus 3. Further, by this step, the expected error time can be based on the average speed of the plurality of vehicles, and is more objective.

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 The second trading time is located in one of the plurality of sets of expected trading time intervals, and the target vehicle is determined to form an effective travel time between the first location and the second location. 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. . In this way, it can be closer to the real situation and avoid false positives. occur.
