It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an ETC portal transaction success rate detection method according to an embodiment of the present invention, where the present embodiment is applicable to a case of detecting a transaction success rate of an ETC portal, the method may be executed by an ETC portal transaction success rate detection device, the ETC portal transaction success rate detection device may be implemented by software and/or hardware, and the ETC portal transaction success rate detection device may be configured on a computing device, and specifically includes the following steps:
s110, acquiring the ETC vehicle which inevitably passes through the ETC portal frame to be detected in the preset time period, and randomly sampling the acquired ETC vehicle.
In the above steps, the ETC portal is disposed on each road section between any two toll booths, as shown in fig. 2, the middle part is an interchange overpass, four roads respectively extend out, A, B, C, D four toll booths are disposed on the four roads respectively, and the portal a, the portal B, the portal C, and the portal D are disposed on the roads between any two toll booths among the four toll booths respectively. The ETC portal is used for trading with the ETC vehicle through this ETC portal, in this embodiment, carries out the monitoring of trading the success rate to the ETC portal that arbitrary treating to detect. It should be noted that fig. 2 is only an exemplary diagram of an expressway, and in other embodiments, the ETC portal is provided on any road section for expressways with different layouts.
The method comprises the steps of obtaining an ETC vehicle which inevitably passes through an ETC portal frame to be detected within a preset time period, and restoring a running path of the ETC vehicle according to transaction running data of the ETC vehicle; and judging the ETC vehicle which inevitably passes through the ETC portal frame to be detected within a preset time period according to the restored running path.
The method includes the steps that transaction flow data of the ETC vehicle are obtained based on electronic equipment arranged at an expressway exit, wherein the transaction flow data include ETC gantries which are used for conducting transactions with the ETC vehicle, transaction time, transaction amount and the like, the ETC gantries which are used for conducting transactions with the ETC vehicle in sequence are determined according to the transaction time of the ETC vehicle and each ETC gantry in the flow data, the ETC gantries which are used for conducting transactions with the ETC vehicle in sequence are indicated, the running path of the ETC vehicle is restored according to the determined position information of the ETC gantries which are used for conducting transactions with the ETC vehicle in sequence, the position information of each ETC gantry can be stored in advance, for example, the mapping relation between ETC gantry identification (such as the serial number of the ETC gantries) and the position information can be achieved, and the transaction flow data include the identification of the ETC gantries which are used for conducting transactions. The position information of the ETC portal can be at least one of longitude and latitude coordinates of the ETC portal, a road section name where the ETC portal is located and the position of the ETC portal in the road section.
If the running path of the reduced ETC vehicle comprises the ETC portal frame to be detected, the ETC vehicle can be determined to inevitably pass through the ETC portal frame to be detected. Optionally, the following vehicles are excluded from the determined ETC vehicle which inevitably passes through the ETC portal to be detected: the ETC vehicle that on-vehicle unit dismantled, the ETC vehicle that on-vehicle unit surpassed the validity period, the ETC vehicle of the not plug-in card of composite pass card of getting and the ETC vehicle of the non-valid card of composite pass card of getting, these ETC vehicles though through the ETC portal, but can't be successful produce the transaction with the ETC portal, but carry out image acquisition to it through license plate recognition device, generate the trade water-logging, later calculate the toll according to license plate and motorcycle type, pay at the exit. Although the vehicles do not generate transaction with the ETC portal, transaction flow data can still be generated, so that the vehicles need to be eliminated, interference of the vehicles on success rate calculation is avoided, and the calculated transaction success rate of the ETC portal is more accurate.
Because the number of vehicles which can pass through the main road and the auxiliary road in unit time is different, namely the passing capacity is inconsistent, and the number of destinations which can be reached by the main road is more than that of the auxiliary road, namely the reaching degree is inconsistent, the number of ETC vehicles which trade with the ETC portal frame in each road section is inconsistent, so that the total number of the ETC vehicles which obtain the portal frame to be detected is inconsistent, the total number of the ETC vehicles which inevitably pass through the ETC portal frame to be detected can not be counted, a random sampling method is needed, in the process of random sampling, because the probability of each sample being extracted is equal, the partial samples obtained by sampling can reflect the condition of the whole sample, namely the total number of the ETC vehicles which pass through the ETC portal frame to be detected does not need to be counted, but the partial ETC vehicles which inevitably pass through the ETC portal frame to be detected in a preset time period are randomly extracted, and the condition of all ETC vehicles which pass through the ETC portal frame to be detected can be reflected, the method has the advantages that the interference caused by different vehicle flows in different road sections is avoided, the statistical workload is reduced, the calculation of the transaction success rate of the ETC portal to be detected is simpler, and the calculation efficiency of the success rate is improved.
The preset time period is a preset time period in which statistics inevitably passes through the ETC vehicle of the ETC portal to be detected, for example, the preset time period is 8-10 points, statistics is necessarily carried out on the ETC vehicle passing through the ETC portal to be detected in the time period of 8-10 points, and then random sampling is carried out on the ETC vehicle obtained through statistics, wherein the random sampling method can be as follows: numbering ETC vehicles which inevitably pass through an ETC portal frame to be detected within a preset time period (for example, 8-10 points) according to a time sequence, and extracting samples in a mode of drawing lots or checking a random number table; or an equal number of samples are taken based on a fixed time interval (e.g., half an hour, etc.) within a preset time period (e.g., 8-10 o 'clock), such as 8-8 o' clock half, 8-9 o 'clock half, 9-9 o' clock half, and 9-9 o 'clock half-10 o' clock, respectively.
S120, the ETC vehicles obtained through random sampling are matched with the ETC vehicles of the ETC portal to be detected in the preset time period in the transaction running data of the ETC vehicles.
In the above steps, when the ETC vehicle passes through each ETC portal, each ETC portal deducts the fee from the vehicle, and writes the deduction record into a storage device of the ETC vehicle, wherein the storage device is an On Board Unit (OBU) mounted On the vehicle. When the vehicle passes through an exit of the highway, the electronic equipment reads the record written in the OBU, and then all transaction running data of the ETC vehicle on the highway can be obtained. Optionally, the electronic device at the exit of the highway sends a transaction running data reading request to the ETC vehicle, where the transaction running data reading request carries date information, and the ETC vehicle sends the transaction running data corresponding to the date information in the OBU to the electronic device according to the transaction running data reading request, where the date information in the transaction running data reading request may be, for example, a current date or date range information (a week or a month before the current date, etc.).
The transaction flow data of the ETC vehicle includes: the ETC vehicle comprises a running speed of the ETC vehicle, transaction time of the ETC vehicle and each ETC portal, serial numbers and position information of the ETC portals transacted with the ETC vehicle, the amount of money deducted from the ETC vehicle by each ETC portal, the remaining amount of money of the ETC vehicle and the like. The ETC vehicle of the portal transaction with waiting to detect in the preset time is found through the transaction time of ETC vehicle and each ETC portal and with the serial number and the positional information of the ETC portal of ETC vehicle transaction in the transaction running data. Because of waiting to detect the ETC portal probably exist and the ETC vehicle transaction is unsuccessful, or the condition of not writing in transaction information after the transaction is successful, the event obtains through the transaction pipelining data and waits to detect the ETC vehicle quantity of ETC portal transaction less than the ETC vehicle quantity of actual transaction in the time quantum that predetermines, will be through the transaction pipelining data obtain with wait to detect the ETC vehicle that obtains of ETC portal transaction and S110 in the vehicle of ETC portal transaction and random sampling, ensure that the ETC vehicle that matches successfully is must wait to detect the ETC portal and wait to detect the ETC vehicle that ETC portal transaction is successful. Specifically, in the transaction flow data, whether the ETC vehicle obtained by random sampling is included in the ETC vehicle which is transacted with the portal to be detected is determined, if yes, the ETC vehicle is determined to be successfully matched, and if not, the ETC vehicle is determined to be failed to be matched.
And S130, counting the number of the ETC vehicles successfully matched.
The ETC vehicle which passes through the ETC portal to be detected in the preset time and is determined in the step 120 is matched with the ETC vehicle which is randomly sampled in the step 110, and the ETC vehicle which is successfully matched is counted.
And S140, determining the transaction success rate of the ETC portal to be detected.
The transaction success rate is calculated according to the following formula: the ETC vehicle quantity that matches the ETC vehicle quantity that success/random sampling obtained, in the formula, the ETC vehicle quantity that matches success is the ETC vehicle quantity that matches success of statistics in S130, and the ETC vehicle quantity that random sampling obtained is to in S110 in the predetermined time quantum, must be through waiting to detect the quantity that ETC vehicle that ETC portal carries out random sampling obtained. If the calculated transaction success rate of the to-be-detected portal does not reach the standard, the to-be-detected portal is determined to be the ETC portal which cannot be normally charged, if the calculated transaction success rate of the to-be-detected portal reaches the standard, the to-be-detected portal is determined to be the ETC portal which cannot be normally charged, for example, the standard of the transaction success rate is 90%, if the calculated transaction success rate of the to-be-detected ETC portal is 80% and is lower than the standard of the transaction success rate, the ETC portal is determined to be the portal which cannot be normally charged, and if the calculated transaction success rate of the to-be-detected ETC portal is 95% and is higher than the standard of the transaction success rate, the ETC portal is determined to be the portal which can be normally charged.
According to the embodiment of the invention, the ETC vehicle which inevitably passes through the ETC portal frame to be detected within the preset time period is obtained, and the obtained ETC vehicle is randomly sampled; matching the ETC vehicles obtained by random sampling with the ETC vehicles passing through the ETC portal frame to be detected within the preset time period in the transaction running water data of the ETC vehicles, and counting the number of the ETC vehicles which are successfully matched; by the calculation formula: the ETC vehicle quantity that matches the ETC vehicle quantity that successful ETC vehicle quantity/random sampling obtained confirms the transaction success rate of waiting to detect the ETC portal has solved because of the transaction volume inconsistency of each road section ETC portal, leads to the problem that ETC portal transaction success rate calculates the difficulty, has avoided the ETC portal transaction to miss the condition of examining, has improved the accuracy that ETC portal transaction success rate calculated, has realized the effect of high-efficient calculation ETC portal transaction success rate.
