From Targeted "Black Spots" to Area-Wide Pedestrian Safety

Crash reports filled out by officers have technical limitations that prevent their use in easily mapping crash sites. This study uses an alternative data source to describe and illustrate the geographic distribution of pedestrian crash sites in Montreal, Canada. Data on pedestrian victims were extracted for a 5-year period (1999–2003) from ambulance services information systems. The locations of crash sites and pedestrian victim density were mapped using a geographic information system. Pedestrian "black spots" were defined as sites where there had been at least eight pedestrian victims. Results showed that the 22 identified black spots represent only 1% of all city intersections with at least one victim and 4% of all injured pedestrians, whereas 5082 victims were injured at >3500 different crash sites. The number and population rates of injured pedestrians are greater in central boroughs. Accordingly, the density of pedestrian victims is much higher in central boroughs. Over the 5-year period, in some central boroughs, pedestrian crashes occurred in up to 26% of intersections. These findings indicate that most pedestrians were injured at locations that would have been missed by the black spot approach to analysis and intervention.
