Abstract:This report describes the data collection procedures, the data analysis methods, and the results gained from the on-site evaluations. The content of the report is as follows: Chapter 2 - State Profiles. This chapter includes descriptions of the organizational structure of personnel at each of the test sites, the site layouts, the Crescent equipment configurations, and the operational procedures used. Chapter 3 - Evaluation Approach. The approaches used for the on-site operational and equipment analyses are described for each site. Chapter 4 - Data Analysis Approach. The approaches used in the analysis of the on-site evaluation data are described. Chapter 5 - Evaluation Results. The description includes the significance of the results and highlights other factors of interest. The results are presented in three sections covering the equipment accuracy assessments, the operational analysis and the interviews undertaken with on-site personnel. Chapter 6 - AVI Testing. As explained in Chapter 3, a limited scope of testing of the AVI equipment was possible within the on-site evaluation. Chapter 6 presents results from acceptance testing that was undertaken outside the Crescent Evaluation project. These results reflect the operational accuracies that are achieved by the AVI equipment used within the Crescent system. Chapter 7 - Cost-Benefit Analysis Model. A cost-benefit analysis framework has been developed and is utilized to determine the potential costs and benefits available from the Crescent system. This chapter describes the model and the assumptions used. Chapter 8 - Conclusions and Recommendations. The conclusions drawn from both the on-site evaluation and the cost-benefit analysis model are presented in this chapter. From these conclusions and incorporating the findings of the other Crescent Evaluation studies, a series of recommendations have been developed. These are also presented in Chapter 8. To complement the main report there are two annexes, Annex A describes the statistical tests that have been undertaken. Annex B presents more detailed results from the on-site evaluation. These have been summarized in Chapter 5, and include observed equipment accuracies for AVC, WIM and automatic axle spacing measurement equipment, and the operational analysis that was performed. Due to its large size, this document has been segmented into multiple files. All files separate from this main document file are accessible from links (blue type) in the table of contents or the body of the document. 2 Appendices.
