Mr. Loumiet is a train and traffic accident reconstructionist and holds a B.S. degree in Mechanical Engineering from the University of Missouri-Kansas City. Since 1990, he has consulted on hundreds of railroad and highway accident cases in litigation for both plaintiffs and defendants, and has testified as an expert in Federal, State, and local courts across the U.S. In 1994, Mr. Loumiet founded James R. Loumiet & Associates, Inc., a consulting firm specializing in train and traffic accident reconstruction. Previously, he was a researcher on federal highway safety projects involving highway work zones, highway barriers and crash cushions, and traffic accident reconstruction. He participated in the revision of Part VI of the Manual on Uniform Traffic Control Devices and some of his research has been incorporated into published AASHTO policies.
Mr. Loumiet has participated in braking and crash tests involving motor vehicles and trains. He has authored numerous technical papers and reports dealing with accident reconstruction, train dynamics, and highway safety, some of which have gained national recognition. Mr. Loumiet is also a member of several professional societies.
