This dataset includes the final Technical Note and accompanying GIS datasets delivered by Cardno and UNSW for their proof-of-concept Passive Surveillance Index (PSI) trial in Parramatta, through TfNSW’s Safety After Dark Innovation Challenge (SADIC). The PSI scores walking routes based on quantifiable indicators. The tool may be a starting point for planners to make informed decisions on how safe cities may factor passive surveillance into their design. The web map visually displays the PSI for different times of the night across the trial area. This website works best using the Google Chrome browser.
