Abstract This report summarizes research for TxDOT Project No. 0-6487, which enhanced and expanded the open-source Project Evaluation Toolkit (PET) to evaluate operational strategies for transport project (and policy) impact evaluation. Such strategies include advanced traveler information systems, speed harmonization, shoulder use, incident management, and ramp metering. PET is a user-friendly, comprehensive sketch-level project evaluation planning tool, anticipating changes in travel demand, traffic patterns, crashes, emissions, traveler welfare, reliability, project net present values, benefit-cost ratios, and other performance metrics. PET also tracks project financing measures for a number of project types, including capacity expansion projects, tolling, and managed lane facilities. Beyond operational strategies, this project increased PETs scope, usability, and accuracy in other ways. For example, new transit and fixed-cost features allow for deeper and more meaningful mode choice and network modeling, while a network visualization module dramatically facilitates user generation and editing of modeled networks. New features also allow users to bypass PETs built-in travel demand model (TDM) to evaluate external TDM outputs directly. Such features allow more sophisticated modelers the chance to apply PET to their own TDM outputs, for a much wider variety of outputs than traditionally available to transportation planners and engineers. As noted, outputs include emissions, crash counts, reliability, toll revenues, and benefit-cost ratios, among others. PET capabilities include budget allocation tolls, multi-criteria assessment (of multi-faceted projects, using decision envelopment analysis), and sensitivity analysis (to produce distributions of project performance metrics, recognizing that many/most inputs have some uncertainty associated with them). Alongside these scope-enhancing changes are updates to crash and emissions estimation procedures, reflecting the latest Highway Safety Manual and EPA emissions (MOVES) estimation routines. This project also developed a variety of professional supporting materials for PET users, including an extensive Users Guide, presentation materials (for rapid training of new users), and four urban roadway networks (for Dallas-Fort Worth, Austin, Houston, and San Antonio).
