Evaluation of Weigh-In-Motion Systems in Alberta

  • Weigh-In-Motion (WIM) systems are used for dynamic traffic data collection. These sensors are capable of collecting various truck characteristics such as weights, speed, and dimensions. Alberta Transportation (AT) installed 20 WIM sensors in six different highway sections across Alberta in 2004. The accuracy of these measurements and their effects on pavement design is evaluated in this thesis.
    To investigate the accuracy of the WIM sensors a verification test was conducted on the sensors from 2004 to 2010. The errors in the WIM sensors’ measurements were estimated. Statistical analysis was performed on the database of errors.
    Statistical analysis on the verification test program database showed that WIM weight errors do not comply with current standards and there is a need to improve the system. The new predicted pavement performance results from the Mechanistic Empirical Pavement Design Guide (MEPDG) showed that local WIM traffic data inputs should be used for Alberta highways.
