CCTV has been widely used for crime prevention but there is little evidence on its value for criminal investigation.
This project aims to identify how often CCTV is useful in investigations of different types, and in what circumstances.
The researcher will be given access to records of 250,000 investigations conducted by British Transport Police over five years.
Statistical analysis will be carried out to identify how often CCTV is (a) available to and (b) useful for investigations. Logistic regression models will be used to identify the circumstances in which CCTV is and is not most likely to be useful.
First stage of the research has been published:
