Embodiment Construction

[0022] Hereinafter, the present invention will be described in detail based on the drawings, and the purpose and effects of the present invention will become more apparent.

[0023] The method for generating a pedestrian business district based on an electronic map of this embodiment includes the following steps:

[0024] The first step is to calculate the critical distance value according to the given walking time and walking speed.

[0025] In this example, given a walking time of 8 minutes and a walking speed of 1.2 meters per second, the critical distance value is 576 meters.

[0026] The second step is to select opportunities ( figure 1 M), and transfer the opportunity point M to the nearest road arc node M′, and add this node to the opening table; if there is an overpass on the road arc mapped to the opportunity point M, then Add the nodes at both ends of the road arc where the brother points of the flyover are located to the opening table; if there is a zebra crossing on the ro...

Abstract

The invention provides a generation method of a pedestrian business district based on an electronic map. The method comprises the following steps: screening nodes from the inside to the outside starting from an opportunist by sufficiently utilizing a topological structure among road nodes in the electronic map; saving nodes with distances to the opportunist less than a critical distance value in a closed table; and generating a pedestrian business district by combining an interpolation point on a critical arc section. Because the topological relationship among the road nodes is utilized, the screening process of the nodes is quickly and ordered, and the generation method has the advantages that: when nodes are added to the closed table, nodes in a start table are nodes closest to the periphery of the business district, so that the critical arc section can be found conveniently and quickly; and the method takes factors of pedestrian bridges and zebra stripes, so that the generated pedestrian district is closer to the reality, and accurate and effective information is provided to a site testing decision. The method has a smart conception, and can be used for quickly and accurately generating the pedestrian business district, so that the site testing efficiency is improved.

Description

Technical field [0001] The invention relates to a method for generating a pedestrian business district based on an electronic map. Background technique [0002] In recent years, with the reform of the economic system, the acceleration of urbanization and the continuous improvement of residents' living standards, the retail industry has become the fastest growing, most open, and one of the most competitive industries in China. A large number of new types of retail industries have emerged, such as chain supermarkets, hypermarkets, shopping malls, and restaurants. The diversification of business formats, the chaining of operations and the individualization of consumer needs all urgently need to comprehensively use effective technical tools to conduct a reasonable analysis of the retail business location, business circle form, commercial space structure, and competitive environment. [0003] The catering industry is a very important type of retail industry and plays a pivotal role in ...
