Scenario Planning of Future Freight and Passenger Traffic Flows across the U.S.-Mexico and U.S.-Canada Borders

The U.S. Department of Transportation, through the Federal Highway Administration, initiated a study, in cooperation with Transport Canada and the Mexican Secretariat of Transportation and Communications, to develop U.S.-Mexico and U.S.-Canada projections of future freight and passenger volumes over the next 30 years (2015 – 2045) from a North American framework and a regional border perspective.

Data Source:

FHWA NPMRDS (National Performance Management Research Data Set): FHWA has acquired a second (v2) national data set of average travel times on the National Highway System for use in its performance measures and management activities.

The Passenger Level of Travel Time Reliability Index (LOTTR) is calculated per 23 CFR §490.511.

LOTTR = 80th Percentile Travel Time /50th Percentile Travel Time.

Truck Travel Time Reliability (TTTR) Index is calculated per 23 CFR §490.611.

TTTR=95th Percentile Travel Time /50th Percentile Travel Time.

Any questions related to NPMRDS, please contact Rich Taylor.

The National Network of conventional combination trucks was authorized by the Surface Transportation Assistance Act of 1982 (P.L. 97-424) and specified in the U.S. Code of Federal Regulations (23 CFR 658) to require states to allow conventional combinations on "the Interstate System and those portions of the Federal-aid Primary System … serving to link principal cities and densely developed portions of the States … [on] high volume route[s] utilized extensively by large vehicles for interstate commerce … [which do] not have any unusual characteristics causing current or anticipated safety problems."

Conventional combinations are tractors with one semitrailer up to 48 feet in length or with one 28-foot semitrailer and one 28-foot trailer, and can be up to 102 inches wide.
