Research Reports

Truck Flows and Loads for Pavement Management

Description:

This report describes procedures state departments of transportation can use to determine the location and frequency of their truck monitoring activities. The objective of the recommended procedures is to help a state design a program that cost-effectively meets its needs for traffic data within its overall pavement management structure. If the data are collected and used properly, they should provide a much more effective pavement design and management process than is currently available, thereby increasing the reliability of pavement designs; decreasing overall pavement construction, maintenance, and rehabilitation costs; and improving a state's ability to manage its pavement infrastructure.
This summary report discusses:

  • the procedures required to determine the number and distribution of continuous, automatic vehicle classification (AVC) and weigh-in-motion (WIM) devices within a state;
  • a system for using the data gathered with these devices to adjust data from short duration vehicle classification and WIM counts to better estimate average annual conditions;
  • the appropriate length of short duration AVC and WIM counts required to develop annual average estimates of travel within specified levels of precision and
  • research performed in Florida and Washington that illustrates the variability of vehicle classification and truck weight data that states can expect to find on their roads.
