Abstract
A method for splitting ambiguous path toll based on weight charge and weight detection is as follows: (1) a vehicle weighing facility is installed on an ambiguous path of a freeway; (2) the weight facility is used for recording the weight of all passing vehicles and uploading the data to a networking toll allocation center; (3) weighing charge data of monthly general road network is used for calculating weight data showing a vehicle passes through a weighing section, but does not drive the whole distance of the ambiguous path; (4) the total toll of the shortest path of the ambiguous path is counted; and (5) the weight data of vehicles passing through the ambiguous path is used as the basis of splitting toll to split toll. On the basis of not changing the existing charge mode, the invention splits the toll of the ambiguous path, thus being capable of obtaining objective data with relatively small deviation from the actual weighing charge, unnecessarily altering the charge system greatly and being non-invasive to the existing charge system. The method is a necessary supplement to monitoring the weight of vehicles on road surface.
Description
Technical field
The present invention relates to a kind of ambiguous path toll splitting method based on weight metering charging and weight detecting, is the weight metering charging of ambiguous path toll on a kind of highway and the fractionation statistical method that the road surface weight detecting combines.
Background technology
Along with the fast development of highway, a lot of highways has all formed annular road network.For convenience, allow vehicle pass through charging section efficiently, comprise that all closed turn pikes of highway have been carried out networked fee collection.
Based on the networked fee collection environment, the path of vehicle in road network is uncertain, when the length difference of two paths is very big, charges according to shortest path; When the length difference of two paths was little, ambiguous path had just appearred.Belong to same owner as ambiguous path, do not exist expense to split problem, if ambiguous path belongs to different owners, toll splits problem and has just highlighted.
Existing method for splitting
At present, mainly contain two kinds at highway ambiguous path toll splitting method: accurate Split Method and probability Split Method.
Accurate Split Method
Accurately splitting is according to vehicle actual travel path, collects and split toll, the actual travel path of each vehicle in the correct decision road network, thus solve ambiguous path problem in the road network.Present method mainly contains two kinds of license plate recognition technology and RFID radio frequency automatic identification methods.
(1) license plate method of identification
The gantry type plate recognition system is installed on the ambiguous path of highway, information such as time, website and license plate numbers is input to the database of networked fee collection settlement center, as the foundation of inquiry, clearing.The license plate method of identification has does not influence wagon flow cruising, advantage that operation and maintenance cost is low, but the accuracy rate that image is captured and car plate is discerned has much room for improvement at present, general error rate is all between 15～20%, and the information transmitted amount is very big, resource consumption to system is very big, also to consider the reflections affect of car plate cleaning, installing and fixing property, special inclement weather and car light in addition, be restricted so use and promote all.
(2) RFID radio frequency automatic identification method
RFID radio frequency automatic identification method is by being installed in the other read write line of highway, and through out-of-date, the information of finishing to visa card writes at vehicle, write down this vehicle through the path, thereby discern the information of vehicle process automatically.The deficiency of this method is that the driver practises fraud easily, can refuse the roadside device writing information easily by the shielding visa card.
The probability Split Method
The probability Split Method is theoretical for basic by traffic equilibrium or lack of balance, set up various theoretical models and algorithm, the traffick Traffic Distribution and the distribution of analytical calculation certain high-speed highway network, thus determine the driving path of whole trip traffic in the road network or the possible driving path of bicycle.By probability calculation, can determine the distribution of the whole driving path of vehicle in the road network.Therefore, when the split mode of networked fee collection is when splitting by settlement center is unified, just can be according to the distribution of the whole driving path of vehicle in the road network, split the toll of ambiguous path by interval sometime.Main method has at present:
(1) factual survey method
With sometime the section vehicle actual travel path is investigated, according to the rule that statistics draws, as the distinguishing rule of later vehicle running path, the result splits toll in view of the above.This method is represent the regularity of integral body with statistics of a certain period, and road user also is uncertain to the selection in path, so this method has certain limitation.
(2) ratio is consulted method
Hold consultation by the relevant owner who relates to the ambiguity highway section, determine that each owner splits the way of the amount of money.This method has certain deviation, but owner both sides if can reach certain common recognition, then have certain operation possibility, but split to lack certain scientific basis, if the owner who relates to is more, reaching an agreement property suggestion difficulty relatively.
(3) road network balancing method
Utilize Fare Collection System inlet, outlet (O-D stream) data and the main line traffic of traffic surveillance and control system junction to detect data, by Model Calculation, overall equilbrium goes out each link flow, thereby determines the driving path between road network flow distribution and the origin and destination.The deficiency of this method is the influence that does not reflect weight, and is bigger with actual weight metering charging deviation.

Summary of the invention
Above-mentioned deficiency at prior art, the purpose of this invention is to provide a kind of highway ambiguous path toll and split statistical method, this method is to split problem at the ambiguous path toll, with the vehicle weight data is main foundation, utilizes the method for statistics that toll is calculated, splits; Can access and the less objective data of actual weight metering charging deviation; Can solve ambiguous path toll fractionation question at issue between different highway owners.
The scheme of finishing the foregoing invention task is as follows, and a kind of ambiguous path toll splitting method based on weight metering charging and weight detecting is characterized in that step is as follows:
(1). on the highway ambiguous path, the mounting vehicle weighing-appliance;
(2). utilize the weight of all vehicles of vehicle weighing equipment records process, and tear data upload to networking open the account center;
(3). utilize every month system-wide net weight metering charging data computation: by the cross section of weighing, but do not travelled the weight data of ambiguous path whole process;
(4). count the total toll of ambiguous path shortest path;
(5). utilize ambiguous path to pass through the vehicle weight data and split foundation, carry out expense and split as toll.
Say that more specifically and more optimally each step and computing formula are as follows in the above scheme:
Dynamically title is installed, with all the car weight C1 and the C2 (see figure 1) that dynamically claim to detect every month this section of process on the road surface of highway ambiguous path;
Utilize every month system-wide net weight metering charging data, calculate, still do not cover the weight A1 and the A2 (see figure 1) of ambiguous path whole process by dynamic title section;
The gross combination weight of travelling by way of shortest path is: C1-A1;
Account for the ratio Z=(C1-A1)/(C1-A1+C2-A2) of the omnidistance gross weight of ambiguous path by way of the gross combination weight of shortest path;
Utilize every month system-wide net weight metering charging data, count through the omnidistance total toll G of ambiguous path shortest path;
The shortest path highway section should split the amount of money: G * Z;
The long path of the ambiguous path gained amount of money is: G-G * Z.
The theoretical foundation of the technical program
Lorry adopted the weight metering charging mode during some places (for example, Chinese Jiangsu) networking charging system weighed at present: under the situation of identical conversion mileage, toll is directly proportional with car weight.Though passenger vehicle still adopts the charge method by vehicle, heavier passenger vehicle charge is higher relatively.
Therefore can adopt the approximate toll ratio that replaces of ratio of weight, according to existing Fare Collection System data statistics, the transformed error of this ratio is about 6%.So the application thinks that can carry out toll with the ratio of weight splits.
With the gross weight of Fare Collection System data computation by certain section, with the dynamic gross weight that claims the actual vehicle of this section of detection, these two data carry out obtaining the current toll fractionation of ambiguous path ratio behind the rational arithmetic.Carry out the fractionation of the current toll of ambiguous path according to this ratio.
The characteristics of the technical program
Do not change and carry out the toll fractionation of ambiguity highway section on the basis that has charging mode now.
Can access and the less objective data of actual weight metering charging deviation.
The fractionation scheme relies on existing weighing type Fare Collection System, but need not transform Fare Collection System significantly, and existing Fare Collection System is not had invasive.
Dynamically claim sense weight according to statistical weight in the Fare Collection System and road surface, the short path toll in the ambiguous path is split.
The section car weight of road pavement detects, and is the necessary complement of road surface car weight monitoring.
