%0 Journal Article %T A Multi-Agent Planning Support-System for Assessing Externalities of Urban Form Scenarios: Results of Case Studies %A Rachel Katoshevski-Cavari %A Theo Arentze %A Harry Timmermans %J Sustainability %D 2010 %I MDPI AG %R 10.3390/su2072253 %X The relationship between various planning-ideas and sustainability is described, using a dedicated multi-agent model and demonstrated by a case study. The analysis supports planning based on preferences and behavior of a target population. Two objectives are addressed: (1) Examine the effect of different planning ideas-scenarios on the development of the built-environment and, in particular, how different planning scenarios can contribute to a sustainable built environment, and (2) Demonstrate the relevancy of the multi-agent model as a tool for planning and evaluating planning alternatives. Four planning scenarios are included and three performance indicators measuring aspects of sustainability (accessibility, mobility, and viability) are employed in the analysis. %K urban planning %K urban form %K planning ideas %K sustainable environment %K planning tool %K planning evaluation %U http://www.mdpi.com/2071-1050/2/7/2253
