- Abstract:
- In order to solve the problem in the neighborhood planning of lacking quantitative research on built environment to lead people to travel in a low-carbon way, a set of ways to identify low-carbon travel block have been firstly established. By using “WeChat” positioning, planning department data and field research data, an index evaluation system based on four factors of transportation survey: travel mode, travel time, travel purpose and travel frequency was constructed. The old urban district of Pucheng as example. Secondly, the index system to characterize the built environment was constructed, reasons for low-carbon travel in the neighborhood were analyzed from the perspective of built environmental characteristics, and suggestions for improvement of low-carbon travel in the old urban district of Pucheng and other similar cities have been obtained. The results show that ratio of residential building area to other types should be set between 4:1 and 3:1. The pattern of bicycle travel is mainly developed, and interval of bicycle lanes should be set between 350 m and 450 m. The ratio of pedestrian street occupying land area should be set between 15% and 20% and the width of road should be limited. The coverage ratio of bus stations with 150 m as radius should be set between 40% and 50%, the coverage ratio of shopping service facility with 50 m as radius should be set between 45% and 60%, and the coverage ratio of entertainment service facility with 100 m as radius should be set between 50% to 70%. The conclusion of research confirms “mix function” and “dense network of road” are helpful for residents to travel in a low-carbon way. At the same time, it is also found that not the higher plot ratio is more conducive to low-carbon travel. Population of small city is limited, and the distribution of professional jobs is scattered, which is not suitable for improving the traditional mode of the volume ratio with bus system. Not the higher coverage rate of bus station is more conducive to residents for low-carbon travel. The high popularization of buses in small city increases carbon emissions for residents’ travel. The study provides a new way of thinking about evaluation of travel carbon emissions in the neighborhood and put forward a basis for the planning of block with low-carbon idea.
