Embodiment 1

[0024] The embodiment of the present invention provides a method for dynamic planning of logistics delivery routes based on big data analysis technology, such as figure 1 As shown, including the following steps S1-S3:

[0025] S1. Use big data to analyze the influence of environmental factors on vehicle speed, and comprehensively analyze the time delay caused by traffic event factors on the road section, and establish a driving time model under multi-factor conditions. Among them, environmental factors include rainfall and fog visibility, and traffic event factors include traffic accidents and traffic control.

[0026] Such as figure 2 As shown, step S1 specifically includes the following sub-steps S11-S16:

[0027] S11. Carry out relationship fitting between the rainfall amount and the vehicle speed reduction coefficient, and calculate the vehicle speed reduction coefficient α in rainy days.

[0028] Such as image 3 As shown, this step specifically includes the followin...

Embodiment 2

[0088] An embodiment of the present invention provides a dynamic planning system for logistics delivery routes based on big data analysis technology, including:

[0089] The positioning device is used to obtain the current vehicle driving position information. In the embodiment of the present invention, the positioning device adopts a vehicle-mounted GPS positioning system. The vehicle-mounted GPS positioning system installs a vehicle-mounted positioning unit on the vehicle, applies GPS positioning technology to determine the position information of the vehicle, and obtains the real-time speed and latitude and longitude of the vehicle.

[0090] The data storage device is used to store multiple sets of delivery route node sequences obtained by re-planning the delivery route at a specific time interval T in each delivery activity. In the embodiment of the present invention, the data storage device uses the SQL Server database to establish the road network information database, a...

Abstract

The invention discloses a method and system for dynamic planning of logistics distribution routes based on big data analysis technology. The method includes: using big data to analyze environmental factors and traffic event factors, and establishing the relationship between various factors and vehicle driving speed. The function of the reduction coefficient or the function of various factors and vehicle travel delay time, using the theory of graph and network to establish the urban distribution road network model, and finally using the A* search algorithm to dynamically plan the optimal distribution route. The present invention fully considers the impact of environmental factors and traffic event factors on distribution routes, thereby solving the problem of urban logistics distribution route planning, can effectively deal with the impact of environmental factors and traffic events on distribution vehicles, and improves distribution efficiency and distribution services level, reducing delivery costs.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation and logistics, and in particular relates to a dynamic planning method and system design of a logistics delivery route based on big data analysis technology. Background technique [0002] In recent years, the process of urbanization and motorization in my country has been accelerating, and urban traffic problems represented by traffic congestion have become a major problem, and urban traffic congestion has seriously restricted the development of urban logistics distribution, which not only increased distribution costs, but also reduced distribution costs. efficiency. Many scholars have focused on the route planning under ideal road traffic conditions in the research on distribution route planning, and have not taken environmental factors (rainfall, fog) and traffic events (traffic control and traffic accidents) into consideration in the planning process. Factors, while the impact...
