Quick scan methods aim at a fast and transparent analysis of alternative solutions to planning problems in a situation of shortage of information. Theygenerate new knowledge about solutions in early stages of decision making and in 'creative experiments' in scenarioanalysis. The importance of quick scan methods is growing within the trend toward moreflexible and interactive approaches in decision making in policy and planning.This article presents a quick scan of alternative technology options to transport problems, in view of their adoption in the market. The technologiesinvolved represent good efforts to contribute to energy efficiency and a reduction of air pollutants. The perspectiveused in this quick scan is spatial by emphasizing the influence of spatial settlement patternsin scenario thinking on future transport.
