Abstract:This report presents a historical analysis of breakthrough research in highway transportation on behalf of the Federal Highway Administration Exploratory Advanced Research Program. It illustrates how transportation-related breakthroughs emerge from long-term, high-risk research. This project addressed three questions: how often breakthroughs occur; when are research advances recognized as breakthroughs; and what allows for the widespread adoption of a breakthrough. The project evaluated candidate projects and identified five breakthrough developments for in-depth study: ramp metering, tunnel boring machines, electronic toll collection, rumble strips, and mechanistic-empirical pavement design. The report draws four conclusions. First, research breakthroughs require an environment of sustained public-sector support for research. Second, breakthrough research outcomes offer solutions to vexing transportation problems and clear benefits for end users. Third, research breakthroughs build on and combine related technological developments across multiple disciplines or by combined expertise across fields. Fourth, breakthroughs require iterative experimental studies and pilot deployments to help ensure widespread acceptance.
