Urban Commuter Traffic Carbon Emission Model Based on Life Cycle

摘要

From the perspective of the life cycle, this paper studied carbon emission of urban commuter traffic and their factors and puts forth the calculation method of commuter traffic carbon emissions based on life cycle. Then, relying on the survey data of Xi'an city and the life cycle research at home and abroad, we calculated the urban commuter traffic carbon emission of respondents. Finally, we applied SPSS software in a multiple linear regression and established an urban commuter traffic carbon emission model based on life cycle. We found that: (1) Carbon emissions from vehicles using were up to about half of the total life cycle carbon emissions. (2) For buses, fuel cycle was the main carbon source. For cars, using parking facilities was the main source of carbon emissions. (3) Factors affecting the commuter carbon emissions were travel distance, travel mode, age and high degree of education (Masters or PhD).
