ITRE has a long-standing commitment to addressing pressing surface infrastructure challenges on state and national highway systems. Research, training, and technical services focus in five key areas: operations, safety and geometrics, work zones, roadway assets, and sensing and instrumentation. Since ITRE’s inception, the Institute has published hundreds of peer-reviewed publications, reports, and guidebooks, and associated tools have been developed and utilized by the transportation profession to advance the knowledge of practitioners. In addition, the Institute trains thousands of transportation workers a year in these focus areas.
