Measuring Perceived Accessibility to Urban Green Space: An Integration of GIS and Participatory Map

by Fariba Sotoudehnia and Lex Comber

Urban green space (UGS) provides free breathing space to take time out from the stresses of contemporary life. This paper aims to measure both physical and perceived accessibility to UGS by using GIS and three qualitative methods and make a comparison between the actual travelled path and the analytically calculated ones. GIS-based network analysis determine only 15% of the total population in Leicester meets physical access up to 300m which has been significantly distributed in the most deprived areas. The results derived from 455 questionnaire show a significant relationship between people age, occupation, car ownership, actual travel time and mode of travel with the frequency of use. The average of actual travelled path (come from 270 routes drawn by people) show a longer travelling distance compared to the average calculated by network analysis. People’s drawn routes show more travels towards GS in the centre of the City compared to those in the north direction.
