Urban road network and function analysis based on space syntax in Xi 'an City

Taking the road network in the third ring road of Xi 'an in 2020 as the research object, based on the space syntax model, the global integration degree and local integration degree are selected as the analysis indicators to analyze its characteristics. The results show that the global integration degree and local integration degree of Xi 'an roads are relatively high, showing the characteristics of high in the middle and low around the periphery, and the correlation between the global integration degree and local integration degree is highly correlated. At the same time, the selection degree is analyzed. Finally, the paper analyzes the spatial flow of the road network, and finds out that the traffic network of Xi 'an is basically reasonable and can meet the needs of travel. This paper hopes to provide some suggestions for future road traffic network planning in Xi 'an.
