TRB Session to Feature LTPP Strategies for Collecting Quality WIM Data
How can your agency improve its collection of weigh-in-motion (WIM) traffic data? Why is it so important to collect quality WIM data? Come find out the answers to these questions and more at a Transportation Research Board (TRB) Annual Meeting session presented by the Federal Highway Administration's (FHWA) Long-Term Pavement Performance (LTPP) program. The session is also sponsored by TRB's LTPP, Highway Traffic Monitoring, and Pavement Monitoring and Evaluation committees. "Leveraging the LTPP Experience for Collecting Quality WIM Data" will be held January 24, 2011, from 10:15 a.m. to noon in the Marriott Wardman Park Hotel in Washington, DC. The session will take place in the Thurgood Marshall North room.
WIM equipment can be used to collect data on such factors as vehicle and axle weights, axle spacing, speed, and vehicle class. The TRB session will cover the many steps involved in collecting quality WIM data, including implementing a good procurement process; performing regular maintenance, calibration, and validation of WIM equipment; and carrying out regular processing of the data, as well as quality control checks.
For more details on the WIM session, contact Deborah Walker at FHWA, 202-493-3068 (email: firstname.lastname@example.org).
