PreparationPreparation for this analysis involved isolating incidents only related to robbery and theft. The study area is the University of Utah and the data range is 5 yrs. All information was provided by the Spillman Database; any records missing spatial information was discarded in this analysis.

L(x) is the likelihoodn is the total number recorder incidents related to robbery and theft.L(x) = amount/n *100, where amount is the value of crime occurrence for each category.

Findings• Most frequent times:

8am, 7am, 6pm, 9am, 12pm, 10am, 3pm

• Most frequent days: Tuesday, Thursday, Friday

• Most frequent months: November, January, October, and April

• Most frequent crime location buildings: Medical Center Parking Terrace, University Hospital, University Hospital Parking Terrace, Primary Children’s Medical Center, A. Ray Olpin Union, Kennecott, Museum of Natural History, Warnock Engineering, and Campus bookstore.

• Most frequent crime location roads and parking lots: Red Butte Canyon Rd, Lot 1, Lot 40, Lot 44, and Lot 94

Recommendations• Pursue improvements to Spillman data:

1. Tie all incidents to a specific location.• Address• Intersection of roads (1800 E at South Campus Dr.)• Parking Lot #’s• Building Name or Number

• Use initial study as a baseline and move forward with comparison analysis every quarter or least twice a year.

• Perform a time series analysis to compare month to previous months identifying changes in robbery/theft patterns.

• Consider predictive analysis and modify approach to prevention.

Recommendations (cont.)• Analysis findings going forward will show success in

strategies and areas for improvement. • Correlate class schedules and events to provide further

analysis on campus.
