Transportation

IEI teams have completed transportation and traffic engineering studies, as well as preliminary and final design engineering for roadway, aviation, mass transit and railroad construction projects in all the markets we serve. Our team has the experience and capacity to move your transportation project through the entire design process. Our transportation design services include:

From large scale multi-lane freeway/expressway reconstruction to local intersection improvements, IEI employes engineers who are highly knowledgeable in the requirements of roadway infrastructure projects. Our team creates safe, creative, functional roadways and highways that enrich the local and interstate communities.

IEI traffic engineers focus on the safe and efficient movement of all users of the transportation system. Services range from traffic signal warrant studies and design, to individual intersection analysis or full system/corridor analysis. IEI also has experience in bicycle path design, pedestrian studies, highway capacity analysis, traffic impact studies with trip generation and traffic modeling, and corridor traffic system analysis and programming.

IEI’s rapidly expanding aviation practice encompasses several aspects of airport development including planning, runway design, site design services, airfield design, and roadway access. We offer specialized capabilities in the area of storm water management and drainage design for airport systems. IEI provides design, program management and construction engineering and inspection services for landside and airside projects to improve operations and expand capacity.

IEI’s transit design engineering team conducts feasibility studies, oversees station rehabilitation, and designs commuter parking facilities. IEI also provides construction administration services for transit projects – bridges, train sheds, storage facilities, rail yards, rail segments and stations.
