2. GPS Traces of Police Vehicles GPS transmissions of police vehicles in Camden Transmits every 15 seconds = 1 month

3. Where do police vehicles stop? Why? Indicate where crimes occur Indicate where police expect crimes to occur Indicate where police get stuck in traffic

4. Where do police vehicles stop? All GPS transmissions where speed = 0

6. 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? (response vehicle/safer neighbourhood)
