Oak Ridge
Evacuation Modeling System©
The Oak Ridge Evacuation Modeling System© (OREMS) is a Windows-based software program developed to address
problems encountered in conducting evacuation time estimation studies
using available commercial and public domain software. The goal
was to produce a software program that utilized the latest traffic
simulation software from DOT and would run faster than other models
and simplify the modeling process.
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.
