Abstract
- In order to achieve an accurate description of the urban road network morphology, the morphological characteristics of the road network are divided into two categories: geometric shape and topological structure for analysis. For each type of structural characteristics, corresponding quantitative description indicators and calculation methods are proposed, combined with the computer aided analysis techniques such as Origin and DepthMapX, this paper quantitatively analyzes and compares 8 samples of 4 types of road networks which are common in modem cities and displayed in different development stages. The results show that: (1) compared with the traditional or single - type indicator research, the two types of indicators further show the difference between the internal relationship and composition of the road network. The effect is particularly significant when distinguishing the road network in the historical old city and the road network in the peripheral area. (2) There is a mutual feedback effect between the two types of morphological characteristics : the cell rate, integration and intelligibility show a certain positive correlation. (3) The naturally formed road network appears to have a structure complex, but easier to understand after topological deformation. [ABSTRACT FROM AUTHOR]
