Some uses of OREMS in Emergency Management include:

• determining feasibility of evacuation without detailed route planning,
• identifying bottlenecks that would constrain the flow of traffic,
• assessing the effectiveness of alternative traffic control strategies,
• assessing the effectiveness of different evacuation strategies,
• estimating traffic speed on specific roads of portions of the network,
• estimating queuing times at traffic lights or bottlenecks, and
• estimating clearance times for the network or portions of the network.

Types of specific data produced by OREMS include:

• vehicles on each road segment,
• amount of traffic congestion on each road segment,
• number of vehicles traveling past a given point,
• amount of time a vehicle takes to travel from one intersection to another,
• average traffic speed on each road segment, and
• total time required to evacuate.
