Traffic congestion nationally reached a new peak last year and is greater than ever before, according to a report by the Texas A&M Transportation Institute and INRIX Inc. Their analysis is based on federal data on the number of cars on the road and on traffic speed data collected by INRIX on 1.3 million miles of urban streets and highways.
