Research on the Calculating Method of Low-Carbon City Public Transit Bearing Rate
Low carbon is the trend of the future city development. Based on low carbon city concept, first of all, the reasonable development of low carbon urban traffic modes has been studied, for the slow transport, public transport and private transport between the proportion of low carbon city traffic have been analyzed; secondly, according to the commitments of Chinese government on Copenhagen World Climate Assembly in 2009, it has studied the low carbon city public transport minimum rate calculation method, puts forward the calculation formula of minimum bearing rate; Finally, taking a super-large city in central of China for example and using the formula above, the lowest rate of implementing low carbon urban public transport of the city in 2020 is calculated. Results show that on the basis of the city in 2008, the target year of 2020 is also need to increase 11% of the public transportation bearing rate.
