Abstract: Accurate vehicle weight monitoring is essential for efficient traffic management and road maintenance, particularly in preventing potential damage from overweight vehicles to road infrastructure. Weight-in-motion technology plays a pivotal role in traffic engineering due to its ability to rapidly collect data with minimal traffic disruption. However, the precision of Weight-in-motion stations requires improvement and may be compromised by temperature fluctuations. To investigate this concern, a field test was conducted using electrical resistance strain transducers configured as a full bridge, which ensures consistent temperature sensitivity across sensors. These sensors were installed five inches under the asphalt road surface. This field test includes forty-six passes of vehicles with identical weight at low speeds over nine days within a year and is analyzed for statistical characteristics. The findings of this investigation will provide insights into the benefits of enhancing the accuracy and reliability of vehicle weight measurements.

Learning Objectives:

Attendees can expect to learn the following from this session:

Identify the potential impact of temperature fluctuations on the precision of Weight-in-motion stations and describe the methods used to address this issue.
Explain the role of Weight-in-motion technology in efficiently collecting data while minimizing traffic disruption.
Describe the significance of accurate vehicle weight monitoring in traffic management and road maintenance.
