Calculating method and device for traffic transportation capacity based on track analysis

Abstract

The invention discloses a calculating method and device for traffic transportation capacity based on track analysis, and belongs to the technical field of calculation of traffic transportation capacity. The device comprise a floating vehicle data cleaning module, a floating vehicle track clustering module, a traffic transportation capacity calculating module and a traffic transportation capacity scale evaluation module. Output information of all vehicles passing through an area in some time period is recorded, a track data set composed of single-point data is obtained for the n floating vehicle, and a complete data set is obtained through the floating vehicle data cleaning module; by utilizing the floating vehicle track clustering module, the directed space-time clustering volume meeting the requirements of a specific time sequence and space movement is obtained, a model of the relationship between the transportation capacity and common factors influencing the traffic transportation capacity is constructed, and an association coefficient of the model is extracted to obtain a transportation capacity factor loading matrix; the traffic transportation capacity calculation module isused for solving to obtain the total traffic transportation capacity, and the traffic transportation capacity is graded. The calculating method and device have reliability and scientificity and provide powerful basis for related decisions.

Description

technical field [0001] The invention belongs to the technical field of traffic capacity measurement and calculation, in particular to a method and device for traffic capacity measurement and calculation based on trajectory analysis. Background technique [0002] Transportation capacity is an important indicator to measure supply and demand in the field of transportation and logistics. Accurate capacity calculation can make better use of transportation resources. On the contrary, inaccurate capacity calculation will lead to serious discrepancies between transport demand and supply. balance, showing problems such as under-supply or over-supply. [0003] The research on transportation capacity at the present stage mainly includes the following aspects: First, the adjustment of the capacity structure, through the analysis of the existing transport capacity, the vehicle is equal to the transport capacity in the capacity analysis, which often ignores the special characteristics of...

Problems solved by technology

On the other hand, the traffic capacity is predicted based on existing resources. However, this aspect is often not fully considered. Most of them are measured by the carrying capacity of vehicles, ignoring the influence of factors such as transportation costs and transportation time in the transportation process.

For the research on the use of floating car trajectory data for traffic capacity calculation, there is no related invention research
