This report will be of interest to policymakers and the interested public, but also technical people who want an overview of the findings that is more than a synopsis but less than a full technical report.

Traffic Choices Study - In-Summary. This document serves as an Executive Summary (4 pages) that focuses on a few key findings as opposed to analysis methods.

Participant Comments. A sampling of comments from the study participants.

Final Report. This is the main document (forthcoming), written for an audience that wants a more detailed treatment of key topics and a better understand analysis methods.

Technical Appendices. The Technical Appendices to the Final Report include a number of documents on very specific topics (e.g., specifications of the system for tolling and collecting data via on-board units). Readers wanting details not included in the Final Report should turn to the Technical Appendices for the fullest description and documentation.

This database will be retained and made available to other researchers (with participant information removed) under agreement with the PSRC.
