• Abstract:
  The intent of this project was to examine the spatiotemporal profile of incidents and suggest an initial plan for service patrol deployment for the arterials in Orlando. The study area was defined by the following boundaries: SR-434 in the north, US-17-92, I-4, US-441 in the east, SR-482 (Sand Lake Rd) in the south; and Kirkman Rd, John Young Pkwy and US-441 in the west. Based on a spatiotemporal analysis of crash frequencies and clearance times, the southern part of the study area was identified as the primary candidate for the service patrol program. Numerical simulations to evaluate performance of staged and centrally dispatched service program with one vehicle were undertaken. The results indicated the service vehicle could respond to over 70% of the crashes on an average and that the average clearance time per crash would be around 30-40 minutes. Overall, the service patrol program could result in a reduction of 36 to 45 minutes of clearance time on average per crash. The service vehicle would be occupied for about 3-4 hours/day/shift. It is anticipated that a staged and centrally dispatched service patrol program will be deployed as a pilot in the southern part of the study area. Patrolling-based operations may also be tested for a couple of weeks during the pilot implementation to see if there are any unanticipated benefits. The data collected from the deployment will be used to re-evaluate the program (approximately 18 months after deployment) to make suitable modifications and to make recommendations for the best approaches for deploying service patrols in other arterials in the state of Florida.
