Comprehensive Truck Size and Weight Limits Study: Comparison of Results Report

Chapter 1: Introduction

The purpose of this Comparison of Results Report is to illustrate the results from the USDOT 2014 Comprehensive Truck Size and Weight Limits (CTSW) Study and compare with results from past truck size and weight studies. This analysis focuses on past studies that have findings somewhat comparable to those from the 2014 CTSW Study in terms of the types of truck size and weight limits, and networks examined and the metrics used to present findings. The revised desk scans conducted for the 2014 CTSW Study contain summaries of the studies included in this analysis as well as many other studies that may or may not lend themselves to a direct comparison of the 2014 CTSW Study findings.

This report includes results between other studies and the 2014 CTSW Study for all five Tasks' Technical Reports: Modal Shift Comparative Analysis; Compliance Comparative Analysis; Highway Safety and Truck Crash Comparative Analysis; Pavement Comparative Analysis; and Bridge Comparative Analysis.
