GPS Traces of Police Vehicles• GPS transmissions

of police vehicles in Camden

• Transmits every 15 seconds

= 1 month

Where do police vehicles stop?

Why?• Indicate where crimes occur

• Indicate where police expect crimes to occur

• Indicate where police get stuck in traffic

Where do police vehicles stop?• All GPS

transmissions where speed = 0

Future Ideas

• Closer look at vehicle stops– Identify destinations– Cross reference with other data sources

• Patterns in routing behaviour– Model roads as a spatio-temporal network– Behaviours corresponding to roles?
