With seed funding from the Henry L. Hillman Foundation, Carnegie Mellon University (CMU) created Traffic21 to stimulate a broad community partnership to research, develop and deploy “intelligent transportation systems” leveraging information and communications technologies in the Pittsburgh region. Our goal is to support projects that brand the region as an internationally-recognized hub for “smart transportation” thus attracting further investment in both research and commercialization.


For more than 150 years, southwestern Pennsylvania has developed a transportation infrastructure defined by industry and geography. Today, more than ever, transportation is essential for our economic and cultural vitality. More than two million residents of southwestern Pennsylvania and countless visitors navigate our roads each day. Pittsburgh and its surroundings have garnered an impressive reputation as one of the most desirable places to live, as noted by publications including Business Week, The Economist, and Rand McNally’s Places Rated Almanac. We have a reputation for re-inventing our economy through green innovation and technology. Traffic21 strengthens southwestern Pennsylvania’s reputation considerably with “smart mobility,” which embraces the safety, sustainability, resiliency and efficiency of our transportation system.

Traffic21 research helps the region gain access to state and federal funds to deploy systems that incorporate cutting edge features. This places Pittsburgh at the forefront of the intelligent transportation field nationally, and enhance the region’s ability to attract new industry and improve its economy. Moreover, Traffic21 provides citizens with the tools to improve equity, independence, safety, and provide access to education, healthcare, jobs and the recreational and cultural amenities of our region.

While achieving these laudable goals, our research, education and technology transfer efforts fuel a burgeoning new smart transportation industry creating jobs in the region. We also spur the growth of marketable transportation technologies. Simply put, Traffic21 aligns perfectly with existing efforts of government and community leaders to make southwestern Pennsylvania a safer, greener, and smarter model region for the nation.
