Construction method of customized freight demand thermodynamic diagram

Abstract

The invention discloses a construction method of a customized freight demand thermodynamic diagram. The method comprises: a freight zone is divided and an application backstage carries out statistics on all user demands; the customized freight demand thermodynamic diagram has three diagram layers on an electronic map and color marking and filling are carried out on cargo zones; for a cargo taking demand thermodynamic diagram, arrival time obtaining is realized by estimation of travel time based on route planning the customized freight demand thermodynamic diagram is formed based on a cargo shipment demand thermodynamic diagram and the cargo taking demand thermodynamic diagram; and for the customized freight demand thermodynamic diagram facing cargo taking demands, only a correspondence relation needs to be adjusted, marking is carried out based on the cargo shipment demand thermodynamic diagram and an arrival thermodynamic diagram, and respective thermodynamic diagrams are formed. With the method, different demand objects can be selected according to actual demands and cargo demands are analyzed by using the customized freight demand thermodynamic diagram, thereby realizing reasonable transport capacity allocation and thus realizing transport capacity balancing; and thus the freight demand can be satisfied.

Description

technical field [0001] The invention relates to the research field of cargo transportation thermodynamic maps, in particular to a method for constructing customized freight demand thermodynamic maps. Background technique [0002] Customized freight is a freight method that publishes freight demand and transports through the mobile Internet. Customized freight mainly considers the capacity matching situation, and realizes freight matching according to the actual situation of the truck according to different needs. The freight demand is sent from the mobile Internet terminal, and under the action of the location sharing algorithm, it arrives at the delivery point. However, the uncertainty of the reservation location, drop-off location, and route often leads to insufficient effectiveness of operation scheduling. At the same time, the efficiency of transport capacity allocation is not high, resulting in a shortage of supply in some areas and vacant vehicles in some areas, makin...

Problems solved by technology

According to the application mode of the heat map of passenger transport demand commonly used at present, the time-space switching characteristics of the state of the vehicle in operation state and the state of operation are often ignored. For example, after a vehicle sends passengers to the destination, the state of the vehicle immediately changes to the state of operation. However, the current heat map needs to be counted within a certain period of time (such as 5 minutes or 10 minutes, etc.), and it is difficult to truly reflect the real-time demand situation.

This is also the problem that the current heat map design method does not fully consider the change in the matching of passenger travel demand and vehicle capacity caused by forward-looking vehicle state changes
