Highway freight is a blood vessel of physical economic development, which dominates all transportation modes. The highway freight traffic volume not only is a core index for centralizing the development result of highway transportation, but also is an important reference for reflecting the regional economic development level, and is an important basis for traffic and transportation authorities to realize monitoring of highway freight running conditions and to formulate highway traffic planning, policy and regulation and infrastructure investment arrangement. The highway freight traffic based on the freight attribute principle (referred to as 'attribute freight traffic') comprises the freight traffic completed by all freight vehicles with loading/unloading points in the area, is highly related to the economic development level of the area, and can truly reflect the completion of highway freight transportation in the area.
At present, the highway freight traffic in China is counted according to the registered places (vehicle books) of freight vehicles, and reported to the transportation department step by county, city and province, and the counted objects are business freight vehicles. Therefore, the highway freight volume under the current highway freight statistics system only reflects the freight transportation completion condition of the registered business freight vehicles in the area, the freight volumes of partial local business freight vehicles completed in other areas are included in the local freight volume statistics, and the freight volumes of a large number of local non-business freight vehicles and foreign-origin freight vehicles completed in the area are not included in the freight volumes published by the current statistics system, so that the freight volumes published by the current statistics system have larger deviation from the real highway freight completion condition in the area.
Most of the existing highway freight traffic statistical methods and researches are based on the traditional vehicle-to-vehicle statistical methods, the accuracy of statistical data is improved by utilizing technologies such as GPS, beidou and the like and correction of key parameters, and the obtained statistical data still cannot fully reflect the actual freight transportation completion condition in the area. The implementation difficulty of part of statistical methods is high, the statistical methods are seriously dependent on single data sources such as expressway charging data, road freight special investigation data, GPS data and the like, and the statistical results are unilateral.

Detailed Description
The following description of the embodiments of the present invention is provided to facilitate understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and all the inventions which make use of the inventive concept are protected by the spirit and scope of the present invention as defined and defined in the appended claims to those skilled in the art.
A highway freight traffic calculation method based on the principle of vehicle properties and freight attributes, as shown in figure 1, comprises the following steps:
s1, acquiring data of a home cargo traffic statistical database, wherein the data comprises expressway toll collection system data, common highway intermodulation station monitoring data, manual sampling investigation data, local transportation management department data and local statistical annual-image data;
the database required for completing the local freight traffic statistics is as follows:
the highway toll collection system data comprises toll station information and time for passing the freight vehicles into and out of the highway, the axle number of the freight vehicles, license plate numbers, gross weight of the freight vehicles and driving distance of each transportation route and the like, and all the freight vehicles driving on the highway are classified into 5 types, namely 2-axle trucks, 3-axle trucks, 4-axle trucks, 5-axle trucks and 6-axle trucks according to the axle number of the freight vehicles.
The common highway interchange monitoring data comprise types and traffic volumes of freight vehicles passing through the interchange observation range, and all freight vehicles on a common highway are classified into four types, namely small-sized trucks, medium-sized trucks, large-sized trucks and oversized trucks according to types.
And (3) manually sampling and investigating data, namely sampling the past freight vehicles on the expressway and the common highway respectively, and mainly recording the axle number, empty weight, commodity type, license plate number and origin-destination location of the freight vehicles on the expressway and mainly recording the type, cargo capacity, commodity type, license plate number and origin-destination location of the freight vehicles on the common highway.
And local transportation authorities data, such as license plate numbers of local business freight vehicles, road mileage of different administrative grades in the area, and monitoring roads and observation mileage of each exchange station.
And local statistics annual-bill data, namely the total number of local home freight vehicles, the number of local home business freight vehicles and all freight traffic generated by the local home business freight vehicles.
Road freight traffic based on the principle of cargo attribution includes three types: the local cargo volume completed by the local business freight vehicle, the local cargo volume completed by the local non-business freight vehicle and the local cargo volume completed by the foreign business freight vehicle are described one by one later.
S2, calculating the local freight traffic finished by the local business freight vehicle according to the expressway charging system data, the manual sampling investigation data and the local statistics annual survey;
in this embodiment, as shown in fig. 2, the method includes the following steps:
s21, identifying local business freight vehicles running outside the area from the expressway toll collection system and extracting vehicle information of the local business freight vehicles;
s22, acquiring the average empty weight of each axle cargo vehicle running on the expressway according to manual sampling investigation, identifying empty vehicles and eliminating empty vehicle information;
s23, estimating the freight traffic of local business freight vehicles running outside the area and extracting the freight traffic finished by all local business freight vehicles from the local statistical annual survey;
s24, subtracting the estimated freight traffic of the local business freight vehicles running outside the area according to the freight traffic of all the business freight vehicles of the local business, so as to obtain the local freight traffic of the local business freight vehicles.
Through investigation and interview, we found that local business freight vehicles hardly run all the way on ordinary highways in other areas, usually through highways. In this case, we can estimate the volume of freight generated by local business freight vehicles in other areas based on the highway toll system. In addition, all shipments completed by local business freight vehicles can be obtained directly from local statistical yearbooks. Thus, local cargo traffic T accomplished by local business freight vehicles c The estimation model of (2) is
in the formula ,Tyc All freight volumes completed for local business freight vehicles; i is the axle number of the freight vehicle (generally divided into 5 categories: 2 axle truck, 3 axle truck, 4 axle truck, 5 axle truck, 6 axle truck); k is the kth heavy vehicle journey of the local business freight vehicle on the expressway of other areas; n is n ci The total number of heavy vehicle trips for the local business freight vehicle on the expressway in other areas; q ik The total weight of the vehicles and goods of the kth heavy vehicle journey for the local i-axis business freight vehicle to travel on the expressway of other areas; q ei Is the average empty weight of the i-axle freight vehicle on the highway.
S3, calculating the local freight traffic finished by the local non-business freight vehicle according to the expressway charging system data, the manual sampling investigation data, the local transportation administration data and the local statistical annual-check;
in this embodiment, as shown in fig. 3, the method includes the following steps;
s31, extracting license plate numbers of local business freight vehicles from local transportation authorities;
s32, respectively extracting travel information of the local business freight transportation vehicle and the local non-business freight transportation vehicle from the expressway toll collection system through license plate number comparison;
s23, acquiring average empty weight of each axle of freight vehicle according to manual sampling investigation, identifying empty vehicles and eliminating empty vehicle information;
s24, calculating average load difference coefficients of the local service business freight vehicles and the local service non-business freight vehicles;
s25, the number of local service business freight vehicles and the total number of all the local service freight vehicles are extracted from the local statistics annual notices, and the local freight traffic volume completed by the local service non-business freight vehicles is calculated according to the average load difference coefficient obtained in S24 and the occupation ratio of the local service business freight vehicles.
TypicallyNon-business freight vehicles are almost exclusively engaged in short-haul local transportation, and all transportation activities are closely related to local economic development, so that the volume of freight completed by local non-business freight vehicles is considered to be the local volume of freight. Local cargo volume T completed by the local non-business freight vehicle n The estimation model of (2) is
in the formula ,Nc The number of local business freight vehicles; n is the total number of all freight vehicles of the local books; t (T) yc All freight volumes completed for local business freight vehicles; lambda is the average load difference coefficient of the local business freight car and the local non-business freight car, and can be calculated by the following formula:
wherein; i is the axle number of the freight vehicle (generally divided into 5 categories: 2 axle truck, 3 axle truck, 4 axle truck, 5 axle truck, 6 axle truck); h is the h heavy vehicle travel of the local i-axis non-business freight vehicle running on the local expressway; n is n ih The total number of heavy vehicle strokes for the local i-axis non-business freight vehicle to travel on the local expressway; q i h is the gross weight of the vehicle and cargo of the h heavy vehicle travel of the local i-axis non-business freight vehicle on the local expressway; q ei The average empty weight of the i-axle freight vehicles on the expressway; f is the f heavy vehicle journey of the local business freight vehicle on the local expressway; n is n if The total number of heavy vehicle strokes for the local i-axis business freight vehicle to travel on the local expressway; q if Gross weight of the vehicle for the f-th heavy journey of a local i-axis commercial freight vehicle on a local highway
S4, calculating the local freight traffic volume finished by the foreign cadastral freight vehicles according to the expressway charging system data, the manual sampling investigation data, the common highway intermodal station monitoring data and the local transportation administration data;
in this embodiment, as shown in fig. 4, the method includes the following steps:
s41, identifying foreign cadastral freight vehicles running in the area from a highway toll collection system, and extracting gross weight and journey information of the vehicles and the cargoes;
s42, acquiring the average empty weight of each axle freight vehicle running on the expressway according to manual sampling investigation, identifying the empty vehicle and providing empty vehicle information, and estimating the local freight traffic of the foreign cadastral freight vehicle on the expressway in the area;
s43, calculating traffic volumes of foreign cadastral freight vehicles monitored by interchange stations at all cross-regional outlets of common roads with different administrative grades;
s44, calculating the freight volume finished by the foreign cadastral freight vehicles monitored by all inter-regional outlets of the common highway according to the average carrying capacity of all types of freight vehicles on the common highway by manual sampling investigation, and expanding the calculated freight volume according to the total number of inter-regional outlets of the common highway to obtain the home freight volume finished by the foreign cadastral freight vehicles on the common road in the region.
The local cargo traffic of the foreign-origin cargo vehicles can be divided into two types, namely, the local cargo traffic generated by the foreign-origin cargo vehicles passing through the expressway and the local cargo traffic generated by the foreign-origin cargo vehicles not passing through the expressway (only running on the ordinary highway). That is, the local cargo traffic generated by a transit trip of the foreign-cadastral cargo vehicle passing through both the expressway and the ordinary road is included in the category of the local cargo traffic generated by the foreign-cadastral cargo vehicle passing through the expressway. Thus, the local freight traffic T completed by the foreign cadastral freight vehicle nc Can be expressed as
T nc ＝T nce +T nco
in the formula ,Tnce Home cargo volume, T, generated for routing off-highway cadastral cargo vehicles nco The local freight volume generated for foreign cadastral freight vehicles passing only ordinary roads.
Wherein, the calculation formula of the local freight traffic volume generated by the foreign cadastral freight vehicles on the expressway is as follows
Wherein m is the mth heavy vehicle travel of the foreign caddy i-axis freight vehicle running on the local highway; n is n im The total number of heavy vehicle strokes of the foreign cadastral i-axis freight vehicles running on the local expressway; q im Gross weight of the truck for the mth heavy truck journey of the foreign caddy i-axis truck on the local highway; q ei Is the average empty weight of the i-axle freight vehicle on the highway.
Also, by investigation and interview, we have found that foreign-nationality freight vehicles hardly travel all the way on ordinary roads in the local area, typically engaging in trans-regional transportation. In this case, we can estimate the local freight volume generated by foreign-nationality freight vehicles on the ordinary highway based on the truck journey of the trans-regional transportation. In addition, not all the common highways of the local area boundary are provided with intermodulation stations, and the freight traffic generated in the observation range of the intermodulation stations is spread according to the number of transregional outlets of the common roads, so that the freight traffic of all the belonging areas generated by the cadastral freight vehicles on and off the common highways is obtained. Unlike highway toll systems, traffic stations only recognize the traffic volume of different types of freight vehicles and not the gross weight of the vehicle. We need to obtain the average load of each type of freight vehicle by manual sampling investigation.
Therefore, the calculation formula of the local freight volume generated by the foreign cadastral freight vehicle on the common highway is
Wherein g is the administrative grade of a common highway provided with a cross station, and comprises four types of national roads, provinces, counties and villages; n (N) go Common highway with administrative grade gTotal number of cross-zone outlets; m is M go The number of the cross-regional exits of the common highway with administrative grade g and provided with the inter-modulation stations; r is the r-th intermodulation station at the cross-regional exit of the common highway with the administrative grade g; n is n gr The total number of the cross-regional export intermodulation stations of the common highway with the administrative grade of g; j is the type of freight vehicles on common roads, including minivans, medium vans, large vans and oversized vans; a, a grj The traffic quantity of the j-type freight vehicles monitored by the r-th exchange station deployed on the common highway with the administrative grade of g; q oj Is the average loading capacity of the j-type freight vehicles on the common highway.
S5, calculating highway freight traffic based on vehicle properties and freight attribution principles according to the local freight traffic completed by the local business freight vehicle, the local freight traffic completed by the local non-business freight vehicle and the local freight traffic completed by the foreign business freight vehicle.
To sum up, the calculation formula of the highway freight traffic based on the freight attribute principle in this embodiment is as follows
T＝T c + n + nc
Wherein T is the freight traffic of all roads based on the principle of goods belonging to the ground, T c Local freight traffic, T, for local business freight vehicles n Local freight traffic, T, for local non-business freight vehicles nc The local freight traffic for foreign cadastral freight vehicles.
