Abstract

The concept of urban planning in China is gradually shifting from the closed community to the open block, so as to share interior road to the public and then optimize the road network layout. However, there is a lack of quantitative research on the specific influence of different block sizes on urban traffic. Therefore, this paper divides the traffic into two parts: traffic inside the block and outside the block, and then analyzes the impact of block size on the traffic performance (such as travel distance, travel time and number of turnings) of different transport modes. Travel time and travel fee are regarded as the generalized travel cost. The results show that under a given network scale, as the increase of block size, the percentage of average total travel time that happens inside the block increases, and the less friendly the system becomes for public transport. For example, the proportion of the average inside travel time to total time of public transportation users is 10% higher than that of private car users in a network with block size 600 m. The impact of block size on traffic performance should be taken more account into urban and traffic planning.
