Encompassing a broad range of innovative studies on planning support science, this timely Handbook examines how the consequences of pressing societal challenges can be addressed using computer-based systems. Chapters explore the use of new streams of big and open data as well as data from traditional sources, offering significant critical insights into the field.Contributions from key scholars from around the world demonstrate how mature the field of planning support science has become in providing support for practitioners to confront diverse problems. The Handbook analyses a carefully selected range of case studies looking at digitization, big data, geodesign, applied modelling, smart city instruments and planning support systems. It addresses key urban challenges including traffic congestion, neighbourhood gentrification and urban heat-island formation, providing examples of how planning practitioners can improve modern urban conditions. Scholars of urban and regional studies as well as human geographers will find this to be a critical reference on the topic. With examples of planning applications from across the world, this will also be a key resource for urban and regional planners and policy-makers.Contributors include: J. Barton, R. Behrens, C.
