RES2024-09: Traffic Data for Network-Level Pavement Structural Assessment and Performance Grade Asphalt Selection
RES2024.09
Tennessee Department of Transportation (TDOT) usually estimates the equivalent single axle loads (ESALs) data at the project level based on traffic data from the radar detector. However, the traffic data which is extrapolated to determine ESALs are not available in a format supportive of network-level analysis. Roadway traffic varies from time, lane direction, and pavement type. Also, the truck traffic may change over time due to the growing populations, and economic conditions. Hence, the default values recommended by design guidelines may not be suitable for traffic networks in Tennessee. A more sophisticated method is needed to alter the traffic data-related factors in ESALs estimations and network-level analysis.
