Abstract
This report documents a research effort to develop requirements and recommendations for establishing a Weigh-in-Motion Test Facility (WIMTF) in California. This study finds that the effectiveness of existing WIM stations needs to be improved. A WIMTF can facilitate an in-depth understanding of the characteristics of various WIM technologies, as well as the development of new methods for dynamic calibration of WIM scales in order to improve the WIM measurement accuracy, which is critical to the effectiveness and efficiency of WIM stations. To prepare for a WIMTF, several sets of requirements, including non-functional and functional requirements, interface requirements, and data requirements for the WIMTF were developed. Potential sites for the WIMTF were evaluated. Based on the requirements, a site recommendation was made. The study also evaluated the benefits and costs of a WIMTF, concluding that the benefits will far outweigh the costs of a WIMTF.
