Statewide Traffic Data Collection, Processing and Quality Control

The New Mexico Department of Transportation currently utilizes the "AASHTO Guide for the Design of Pavement Structures", combined with its own probabilistic design procedure for the design of all flexible pavement structures. These guidelines are used for the design of rigid and composite pavement structures. The Department plans to continue to utilize AASHTO conventions until the Mechanistic-Empirical Pavement Design Guide (MEPDG) is fully implemented. MEPDG provides a more realistic and cost-effective basis for pavement design through better understanding of local conditions. One of the four primary factors for input into the MEPDG process is accurate traffic data. The Department uses several methods to collect traffic data throughout the state. These include nineteen stationary Weigh-In-Motion (WIM) stations, 129 Automatic Traffic Recorders (ATRs), and Automatic Vehicle Classifiers (AVCs) which are used in addition to short duration counts to calculate Average Annual Daily Traffic (AADT) and to estimate projected growth.
