• Resumen

  • This paper evaluates the impact of urban renewal programs (PRU) on creating a safe environment. People’s perceptions of PRU and its impact on security were collected through questionnaires and sketch maps. This study applies a space syntax approach to analyse the spatial and structural properties of successive urban space evolutions and compare them with people’s perceptions of security. The findings reveal a strong correlation between areas with high levels of social housing concentration, poverty rates and insecurity. Surprisingly, visually controlled areas are vulnerable and attractive locations for drug trafficking. Density indicators have a minor influence on the perception of insecurity.
