• Abstract:
  The objective of this study is to determine the sensor survivability, accuracy and reliability of quartz-piezoelectric weigh-in-motion (WIM) sensors under actual traffic conditions in Connecticut's environment. This second interim report provides a summary of the WIM system calibrations, data analysis for FHWA class 9 vehicles, and equipment performance for the period July 1998-October 1999. Field validations of the system were performed using trucks of known static weight during October 1998, March 1999 and October 1999. Evaluations of field performance of the sensors and surrounding pavement were made on a Quarterly basis. In order to track the accuracy and reliability using actual traffic data, an analysis of class 9 (5-axle) trucks was made for the period December 1998 - September 1999.
