Embodiment

[0067] This embodiment provides a method for estimating expressway freight volume, including the following steps:

[0068] Step S1: collect highway flow information;

[0069] The expressway running water information is the vehicle information collected on the expressway within the first period of time;

[0070] Step S2: Calculate the minimum sampling rate according to the flow information of the expressway;

[0071] Step S3: Sampling the vehicle information collected on the expressway in the second period according to the minimum sampling rate, and estimating the freight volume on the expressway in the second period according to the sample taken;

[0072] The duration of the first period and the second period are the same.

[0073] Specifically, collect data on expressways that need to be estimated, and collect vehicle information within the first period of time. These include the number of vehicles passing through the expressway and the corresponding total vehicle weight, ...

Abstract

The invention relates to the field of traffic and transportation statistics, in particular to a method for estimating the freight volume of an expressway, and the method comprises the following steps:S1, collecting expressway running water information, wherein the expressway running water information is vehicle information collected by an expressway in a first time period; S2, calculating the minimum sampling rate according to the expressway running water information; S3, sampling the vehicle information collected by the expressway in the second time period according to the minimum sampling rate, and estimating the freight volume of the expressway in the second time period according to the extracted samples, wherein the duration of the first time period is the same as that of the second time period. According to the invention, the estimation of the freight volume of the expressway is more accurate.

Description

technical field [0001] The invention relates to the field of traffic statistics, and more particularly, to a method for estimating expressway freight volume. Background technique [0002] Freight volume is the quantity of goods that is completed or needs to be transported during the transportation of goods, also known as "commodity volume", "transportation volume" or "transportation volume". It is an abbreviation for the quantity of goods shipped, usually in tons. Although the volume of cargo and the weight of cargo are both expressed in the same physical unit of ton, the nature and meaning of the two are different. The weight of the cargo is the physical attribute of the cargo itself, which is related to different transportation, while the volume of cargo is the quantity of the cargo that is ready to be displaced or has been displaced, and it is the reflection of the labor achievements of the transportation department, so that the use value of the cargo can be realized. S...
