Simulation of Land Use Consequences of Urban Corridor in Kolkata: An Integrated Spatial and Expert System Model

Abstract

The probability of land use to transform under the influence of transport corridors is an economic measurement unit of a specific land use defined by its accessibility level, economic level and spatial interactions. This study examines land use transitions due to development of transport corridor using expert judgement analytic hierarchy process (AHP) for measuring priority ranking of a particular land use to transit to other use, along the second Vivekananda Bridge-Belghoria Expressway(2VBBE) running through a relatively depressed urban fringe of Kolkata, India. Using the rank scores from AHP, a spatial model-Multivariate Grid Analysis (MVGA) was conceptualized to analyze the probability of transition of land activity in the zone of influence. The model has used data of over a period of 16 years (1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006) to find out the Transition Probability Index (TPI) of land use in the congruous lands. MVGA cumulatively uses property values, accessibility, environmental and demographic factors to project the proposed land use structure for 2020. It spatially predicted the land uses which might undergo incredible changes due to the facility development. These results can implicate policies for internalization of benefits of the corridor in urban development of Kolkata Metropolitan Area. 城市走廊开发正在迅速成为印度经济增长的固有组成部分。本文通过作者开发的模型考察了由 于交通走廊发展引起的土地用途变化，模型使用了加尔各答一条高速公路超过16年的土地利用 和走廊发展数据。通过使用包括房地产价值、可达性、环境和人口因素在内的指标，笔者预测 了2020年可能出现的土地利用结构。文中还预测土地用途可能会由于设施开发而发生变化。这 些结论可以影响加尔各答大都市区城市发展中走廊利益内在化的相关政策。 KeywordsUrban corridor, land use transformation, property values, multi-variate grid analysis, analytical hierarchical process, transition probability index (TPI), internalizing of benefits Article Environment and Urbanization AsIA 4(2) 267-286
