A digital tool for sustainable urban planning : A case study of introducing a carpool in a residential area in Uppsala

Abstract: The purpose of this project is to create a simplifiedtool for urban planning, to illustrate how differentparameters affect each other. The municipality ofUppsala and the company Atkins have investigatedthe possibility to implement several themes andaspects in a digital tool. Since urban planning has acomplex structure, only a few aspects are selectedin this report. This is a case study which examineshow an implementation of a carpool in a residentialarea affects the parameters ground use, carbondioxide emissions and social aspects such asridesharing and car ownership. A model has beencreated in MATLAB to visualize the environmentalimpact of a carpool compared to traditional parking.The results show that the environmental impactdecreases as the number of cars in the areadecreases. Further, the sensitivity analysis showsthat social factors may have a great impact on theenvironmental aspects. A decreased car usage andincreased ridesharing, where only traditional parkingis used, can result in an environmental improvementalmost corresponding to an area with only a carpoolsolution with the current car usage and ridesharing.
