Embodiment Construction

[0027] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.

[0028] A method for preprocessing the traffic restriction data along the way of truck navigation, which refers to pre-calculating the traffic restriction data of trucks, and saving the obtained calculation results as preprocessed data, so as to directly obtain the pre-processing data when searching for the traffic restriction data of trucks along the route during the navigation planning process. The method for processing data and improving the calculation speed of route planning specifically includes the following steps:

[0029] S1: Build a binary tree to store calculation results, and initialize the root node of the binary tree;

[0030] S2: Input the traffic restr...

Abstract

The invention relates to the technical field of truck navigation, and discloses a truck navigation on-way traffic restriction data preprocessing method. The method comprises the following steps: S1, establishing a binary tree, and initializing a root node of the binary tree; S2, inputting truck traffic restriction data; S3, matching the truck traffic restriction data to the road section of the bottommost road network; S4, storing the matching result of the bottommost road network into a binary tree; S5, according to a matching result of the bottommost layer road network, matching the truck traffic restriction data to a corresponding upper layer road section; S6, storing a matching result in the step S5 into a binary tree by taking the road network level and the road section number as indexes; S7, performing inorder traversal on the binary tree, and storing truck traffic restriction data corresponding to all road sections in all hierarchical road networks as a data file A; S8, establishing indexes for all road sections in all the hierarchical road networks, wherein the indexes comprise the corresponding truck traffic restriction data quantity and the storage address of the truck traffic restriction data, and the indexes are stored as an index file B.

Description

technical field [0001] The invention relates to a method for processing auxiliary data of truck route planning, in particular to a method for preprocessing and using data of traffic restriction along the route of truck navigation. Background technique [0002] The search function along the route of existing electronic maps on the market solves the needs of drivers, passengers or passenger cars for popular information such as gas stations, charging stations, toilets, service areas, food, and hotels along the route. However, with the development of informatization in the freight market, truck drivers or trucks pay more attention to the information related to trucks along the route, such as data frequently used by trucks such as height limit, weight limit, width limit, truck ban, and overrun checkpoints, so as to Used to avoid penalties, traffic accidents, and even illegal acts. The purpose of the present invention is to propose a preprocessing method for truck navigation data...
