Study Of Traffic Impact Analysis Of Large-Scale Building Project In CBD

Along with our country national economy's sustained development and urbanized advancement's unceasing quickening,the development quantity of city lands rise unceasingly, the large-scale building program develops are getting more and more.in urban CBD. The large-scale building program increases the massive transportation demand causes the CBD transportation service level to drop, thus has caused many transportation questions, carries on the transportation impact analysis to the CBD large-scale building program is just the effective measure to alleviate this contradictory. At present, our home still did not have aims at the CBD large-scale building program specially the transportation impact analysis method, this article is for the purpose of giving some researches to the CBD large-scale building program transportation impact analysis in the key question, attempts to make the technical support for the transportation impact analysis unify the Chinese national conditions.First ,this article give some thorough analysis to the urban CBD and the large-scale construction's transportation characteristic. Based on this, has conducted the research to the urban central collective leadership large-scale building program transportation impact analysis's key question one by one. Introduced the goal year and the peak time interval definite method; Has given the transportation impact analysis threshold value definite method; Proposes using the smoke feather modeling and the category attraction rate legal quantity determination transportation area of influence method; Divides into the background volume of traffic and the project volume of traffic the transportation demand forecast carries on the forecast separately, uses four terrace works to carry on the forecast to the project volume of traffic. To determine transportation shade rattles of the CBD large-scale building program ia, this article division five ranks to the large-scale building program's transportation , according to large-scale male constructed the project to establish the transportation shade to the urban central area transportation influence actual content to rattle the analysis indicator system, had determined each target's quantification method, calculated various targets using the analytic hierarchy process the weight, then to large-scale male constructed the project the transportation shade to rattle carries on the synthesis evaluation, then proposed the alleviation transportation influence concrete improvement measure.The final, selects Chengdu country gold center project as the case, has confirmed the theory is usability and rationality which this article is proposed.
