C. Police Activity in the Fraser Valley (Outputs) In order to assess how the change in the delivery of enhanced traffic enforcement (X) affected the volume and nature of police activity [...] Frequency of Crashes in the Fraser Valley (Outcomes) In order to assess how the change in the delivery of enhanced traffic enforcement (X) affected the frequency of motor vehicle crashes in the Fraser Valley (Y2), existing statistical data was analyzed. [...] Independent Variable (X): Model of Enhanced Traffic Enforcement in the Fraser Valley Region of B. C.
