Abstract:
As the portable weight-in-motion (WIM) technology has been successfully explored and practically used to collect site-specific traffic data in Texas Department of Transportation Research Project 0-6940 Develop System to Render Mechanistic-Empirical Traffic Data for Pavement Design, this standardized guideline was developed to aid users understand more thoroughly the portable WIM system deployment and its operation for traffic data collection. This draft guideline can be used as a main guide for the portable WIM system implementation on Texas highways. As a supporting material, this guideline covers and describes the following points:
1. Portable WIM components and the required accessories.
2. Preparation of the portable WIM installation and highway site selection.
3. Portable WIM setup, installation, calibration, maintenance, uninstallation, and troubleshooting.
4. Automated macros for processing and analyzing portable WIM traffic data, such as volume, speed, vehicle classification, and weight data.
5. Automated macros for generating Flexible Pavement Design System (FPS) and Texas Mechanistic-Empirical Flexible Pavement Design System (TxME) traffic input data for pavement design.
