Overall road network formRoad network formOrganic road network (organic)
Radial network
Grid network (raster)
According to the characteristics of the road network, the hybrid road network can combine the three forms of road network

IntersectionVillage centerNumber of village center areasIt is generally the public activity center of the village, and the road density of the village public center will be higher than that of other areas
Capture distanceMinimum distance between road intersectionsCalculate the distance between each intersection and take the minimum value
Intersection ratioThe ratio between the number of major road nodes and the number of intersections
Minimum angle of intersectionMinimum angle of road intersectionStatistical minimum angle value of road intersection

Road lengthLonger road length Average over longer set of roadsCalculate the average of all road lengths, select the roads that are greater than the length as set A, select the roadsthat are smaller as set B, find the roads greater thanas set A, and the average length of set B is the longer road length. Greater thanis replaced by less thanvalue for shorter road length
Shorter road length Average over set of shorter roads
Longer road elastic zone The range within which the length of longer roads can fluctuateThe average of the absolute values of the maximum and minimum values in set A can be selected to obtain the longer road elastic interval , and similarly, the shorter road elastic intervalcan be obtained
Shorter road elastic zone Shorter road lengths can fluctuate

Road widthMain road width Average width of main roadDetermine the road grade, select three points in a section of road to calculate the average width of the road, calculate the average width of the main road , the width of the secondary road, and the width of the street ; calculate the difference between , , and and the maximum and minimum values of the road width. The average absolute value of the road elasticity interval , , and
Secondary road width Average width of secondary roads
Main road elastic zone The main road can float up and down the flexible range
Secondary road elastic zone The flexible interval that the secondary road can float up and down

Road declination maximumSmaller value of angle between roadsCount the number of smaller angles at the intersection of two roads, remove extreme values, and take the maximum value as the “maximum road declination angle”
Number of roadsNumber of road segmentsThrough the Douglas-Peucker algorithm, the arc road is decomposed into segments of straight roads, and the total number of roads is counted
