Aim: introduce a number of methods to understand and model crime
Mixture of short lectures and practical sessions
A full description is impossible!
Briefly introduce methods and highlight where to go next
You can choose which methods are most suitable for further study
A very useful tool for performing common spatio-temporal analyses
Hot-spot mapping (e.g. Kernel Density Estimation)
Geographic Profilling
Space-Time Analysis
Journey to Crime
.. many others ..
Excellent documentation
No practical session organised, but help is available
Risk Terrain Modelling: GIS techniques to explore the relationship between crime and spatial factors that influence it. E.g.
Public transport
Drug dealers
Schools
Gangs
Parks
Shops
...
Can be used to make predictions
Practical session: Generate a risk surface
Near Repeats
~31% to 76% criminals return to commit further crimes
Crimes clustered in space and time
Criminals return to an area over a few weeks until risk rises or reward drops
Might be thought of as an "optimal forager" strategy
If we can predict their return pattern we can prevent the crimes
Johnson & Bowers (2004); Bernasco (2008)
Practical session: Near repeat calculator and near repeat mapping
Method for estimating populations at the individual level
Also allows us to estimate variables missing in an area
Practical session: modelling a city population
Agent-Based Modelling: A method to simulate the behaviour of individuals
Phenonema are 'grown' from the ground-up
Well suited to crime analysis
Example: Simulating burglary
Practical: Using NetLogo to build an agent-based model
