Abstract: With the rapid development of social economy, the urban road has been far from enough to meet the demand of urban vehicles. Community opening will improve the capacity of road traffic and have significant impact on the urban road network density, road area and traffic conditions. Based on quantitative analysis of community road structure, their surrounding road structure and traffic flow, a mathematical model is constructed to reflect the impact of community opening on road traffic.

Key words: community opening, road optimization, road traffic, road network structure
