Abstract. An analysis of housing issues in the city of Canela (RS, Brazil) has been made in 2008 as part of the development of the Master Plan for Housing. The present paper deals with one component of this analysis, which is the assessment of urban accessibility for low-income population, and its consequences on the treatment of the problem of current shortage of low-income housing and the future demand from population growth until
2020. A three steps method is applied: (i) urban mobility is assessed and mapped on the basis of the road system and the routes of public transport; (ii) accessibility to different urban services, such as public education and health, recreation, consumption and jobs are measured and mapped considering the location of urban facilities, population distribution divided by income and age, and urban mobility; (iii) one map for urban accessibility is produced as a result of the weighted combination of accessibility to different urban facilities. This final urban accessibility map is then overlayed to empty urban lots with size and land value appropriate to low-income housing, and a simulation of their development over the future has been made. The lots with higher accessibility were selected, and the impact of urban development was assessed on the capacity of education facilities. Based on this study, we made some preliminary suggestions for widening places in some schools, the need for a new education facility (location and size) and the extension
