The American Transportation Research Institute (ATRI) has released its annual report listing the worst traffic bottlenecks in the country. The difference between ATRI’s analysis and that of other reports identifying congested corridors is that ATRI specifically identifies granular chokepoints in the nation’s truck freight transportation system using GPS data from over one million trucks. We know carriers that use the report to better plan routes and times of travel to avoid highly congested areas. You can find an interactive map on the ATRI website or download the two-page summary of truck chokepoints.
