Embodiment Construction

[0013] Such as figure 1 Shown: the method of the present invention can dynamically generate crossing channelization map, comprises the following steps:

[0014] 1. First obtain an original electronic map data of urban roads from a third party (such as purchased by the Bureau of Surveying and Mapping). If it is not in .shp format, use the Mapinfo tool to convert it into .shp format, and modify its fields to meet the requirements of channelization . The .shp format is a kind of graphic data format. Common map data formats include: .tab format of Mapinfo, .dgn format of MicroStation, Arcinfo format, .shp format of Arcview, .mif format of Mapinfo, AutoCAD format, The .stb format of Tianze GIS.

[0015] 2. Then the intersection layer is generated from the road layer. The brief process is as follows: traverse all roads in the road layer, calculate the intersection of each road and other roads, and calculate the intersection and all adjacent intersections of the intersection The p...

Abstract

The method includes steps: obtaining data of an original electronic map about urban road; generating map of road junction from road map; channelizing specific road junction, and generating initialized normal road junction with three traffic lanes; editing sections of roads, modifying attribute and shape of sections of road, adding and deleting lanes according to practical situation; process is carried out by superposing each map layer including independent map layers: road, road junction, traffic lane, crosswalk, green area etc. Features are: simple operation, displaying actual status at road junctions, timely change based on actual situation.

Description

technical field [0001] The invention relates to a method for dynamically generating an intersection channelization diagram, which is used in the fields of traffic monitoring and traffic simulation. Background technique [0002] At present, the work of canalization of intersections is generally obtained through CAD manual drawing, which is relatively complicated, takes a long time, and is not easy to modify. Moreover, the artificially drawn channelization map is difficult to use in traffic control software. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for dynamically generating intersection channelization diagrams, which can be used in traffic control and traffic simulation. [0004] In order to solve the above-mentioned technical problems, the present invention provides a method for dynamically generating intersection channelization diagrams, which includes the following steps: [0005] First obtain...
