Transportation and Air Operations

Applying Experience and Technology to Improve Transportation Planning, Safety, and Security

The transportation sector is challenged with increasing and improving transportation safety and security in the face of limited funding, aging infrastructure, and new, emerging threats to infrastructure and lives. Applying multi-modal transportation expertise, real-world experience, and state-of-the-art technologies (including GIS, evacuation models, and travel demand models), IEM provides cost-effective and science-based solutions that address critical issues associated with transportation planning, safety, and security. Our expertise encompasses all modes of transportation, including motor vehicle/bus/ferry/rail/airline (passenger) and motor carrier/rail/air/barge (freight/cargo).

Since 1985, IEM has worked for or partnered and collaborated with the US Department of Transportation and many of its modal administrations, including the Federal Highway Administration, the Federal Railroad Administration, Federal Transit Administration, the Transportation Security Administration, the Federal Aviation Administration, and the Pipeline and Hazardous Materials Safety Administration, numerous state and local transportation departments, Class 1 rail carriers, and some of the largest mass transit agencies and ports in the US.

Our teams of transportation experts are active in key organizations that are collectively working to strengthen transportation standards and policies, and address critical issues facing the industry today. Our staff have served on American Public Transportation Association (APTA) Working Groups and have hosted and played key roles in Federal Transit Administration (FTA) and Transportation Security Administration (TSA) Safety and Security Chief’s Roundtable Conferences. Our Senior Transit Advisor founded and established TSA’s Peer Advisory Group (PAG). We are members of the Transportation Research Board (TRB), providing leadership for the Committee on Hazardous Materials Transportation and the Subcommittee on Crude Oil Transportation, and participating in the Committee on Emergency Evacuations. We have been instrumental in the development of doctrine and guidance publications used for coordinated federal aviation response to disasters, including airport terminal incident response planning, airport-to-airport mutual aid programs, and integrating community emergency response teams at airports.

IEM became one of the first companies to focus solely on emergency management and to use quantitative data and science to inform decisions in emergency management. Over the past 35 years, IEM has grown from a company of one to an employer of over 550 employees, and has provided clients and communities with innovative solutions that produce results and save lives.

The Chemical Stockpile Emergency Preparedness Program (CSEPP) is jointly managed by FEMA and the U.S. Army. The program ensures maximum protection for the communities surrounding U.S. chemical weapons stockpile sites. Since 1993, IEM has provided program integration services to FEMA and through FEMA to the states and counties that are part of CSEPP.

In 1999, FEMA selected IEM to be the CSEPP onsite Program Management and Integration Contractor. IEM worked with program managers to develop a flexible protection framework that broke down the “maximum protection” mandate into measurable benchmarks. These benchmarks have been adopted by emergency managers in 10 states, 40 countries, and one Tribal Nation.
IEM was awarded a five-year BPA with FEMA to continue working to further CSEPP initiatives between 2000 and 2004. During this time IEM was contracted to develop a secure website to facilitate communication and information-sharing among CSEPP planners nationwide who work in different jurisdictions. The website IEM created now has over 1,000 active users who use it as their primary source of CSEPP information. IEM also developed a demonstration version of an interactive computer-based “game” designed to illustrate the effects of different protective action decisions in a CSEPP emergency to citizens in the Madison County, KY, CSEPP community.

FEMA awarded IEM a second five-year BPA from 2005-2011. IEM was asked to provide CSEPP technical and analytical studies, risk assessments, support for development of programmatic guidance and preparation of reports to Congress. IEM was required to evaluate the Oregon CSEPP community’s readiness in the event of a depot incident. IEM also assisted in the planning and execution of regular readiness exercises and supported pre-exercise meetings. IEM’s work for CSEPP has been recognized on multiple levels. In 2004, FEMA and IEM received a Profiles in Innovation Award for Emergency Preparedness and Response Excellence from GOVSEC (Government Security Expo and Conference). IEM continues to work with FEMA to increase preparedness and achieve measurable results.


QEM uses the information gathered from conducting different scenarios to calculate the risk and impact of implementing different risk-reducing strategies. It pinpoints the actions that are the most effective at reducing risk across a wide spectrum of potential events. QEM allows clients to know the best way to allocate funds and bridge gaps in preparedness without spending thousands of dollars to implement ideas that cannot work.

QEM’s methodology has been applied to hundreds of IEM projects, such as readiness assessments, chemical plant mitigation studies, protective action analyses, and hurricane evacuation planning. The U.S. Army and FEMA have repeatedly used QEM technology to assess strategies to protect citizens in case of an accidental release of chemical agents. DOD’s Defense Threat Reduction Agency (DTRA) also utilized QEM to quantify the effectiveness of various chemical defense systems. The software continues to provide valuable solutions to clients.
