城市土地利用规划的交通影响评价建模研究

本文提出了一种基于投入产出关系和连续逼近方法的城市土地利用的交通影响评价模型。作为城市土地可持续利用规划模型的一个子模型,本模型已在桂林市的总体规划中得以实施。在本文中,先简要介绍了城市土地可持续利用规模模型,接着基于投入产出关系估算了分行业的单位产值对应的货物运输量,然后以交通熵和交通周转量作为评价指标,基于投入产出关系、连续逼近方法和Huff商区模式分别建立了货物运输、居民工作出行和居民购物出行交通影响评价模型。

A Modeling Research on Transportation Impact Assessment of Urban Land Use Planning

A transportation impact assessment model of urban land use planning,based on input-output relationand continuous approximation method,is proposed in this paper.As a sub-model of urban land sustainable useplanning model,it has been implemented in the project of master planning at the Guilin City,In this paper,the urbanland sustainable use planning model is briefly introduced,and then the amount of goods freight per production value ofdifferent sectors of industry and different hierarchies of tertiary industry is estimated.The transporation entropy andtransportation turnover value are adopted as assessment indices,based on input-output relation,continuous approximationand Huff commercial pattern,the transportation impact assessment models of goods freight,citizens working trip andcitizens shopping trip are respectively presented in the rest of the paper.
