Exploring Strategies to Deploy Arterial Service Patrol

Based on our our findings, an arterial safety patrol vehicle will be deployed in a small region of Orlando, Florida.

Work description

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. I developed a numerical simulations to evaluate performance of staged and centrally dispatched service program with one vehicle. The results indicated the service patrol program could result in a reduction of 36 to 45 minutes of clearance time on average per crash.

The figure 2 shows the distribution of time for which vehicle will be occupied for each staging location and also for two different scenarios – tolerance time of 0 minutes and 30 minutes. The text in the plots shows the mean occupancy.
