1. Incident-Management In Central Arkansas – An ITS Application Federal-aid Project Number: ITSR(001) ITS meta Lab University of Arkansas at Little Rock

2. An Integrated and Shared System Operators Motorists Incident System

4. Goals of Our Study Model the distribution of incidents Investigate advanced incident detection techniques Choose the appropriate incident-response strategies Perform Benefit/Cost (B/C) analysis

7. Reported & potential Incidents Potential workload at f =40 Risk = 20% Workload = 3 ×20 min Potential workload at v=20 Delay at f = 80 min (including response time) 10 40 30 50 f (1) v (2) 2 1

8. Comparison between Current and Proposed Current Proposed Total Number of Vehicle Dispatches 66,757 66,757 Total Delay Cost (veh-min) 259,787,280 208,343,664 Mean of Work Time (min) 34.54 27.90 Standard Deviation of Work Time (min) 0.79 0.67
