Transportation planning involves evaluating the congestion, safety, emissions, and other impacts of large-scale network improvements and policy implementations. This document is a User’s Guide for the Project Evaluation Toolkit (PET), a sketch planning toolkit developed for evaluating a variety of strategic-and operational-level transportation network improvements. PET’s development was sponsored by Texas Department of Transportation (TxDOT) under TxDOT research project 0-6235 (titled “Sketch Planning Techniques to Assess Regional Air Quality Impacts of Congestion Mitigation Strategies”) and its associated implementation project (5-6235), along with research project 0-6487 (titled “Development of a Performance Measurement Based Methodology to Objectively Compare Operational Improvements with Capacity Additions”). This Guide provides users with a detailed description of PET’s design and specification and a technical guidance in using PET for project evaluation and comparison.

PET is a spreadsheet-based application that offer users a familiar and powerful data manipulation interface for evaluation of abstracted networks’ improvements and modifications. PET includes a travel demand estimation module implemented as a set of external C++ programs for destination, mode, time of day, and route choices, across multiple user classes. Other functional modules, including economic analysis, environmental impact evaluation, safety evaluation, sensitivity analysis, and budget allocation, are implemented in Microsoft Excel spreadsheets. PET can be used with or without its travel demand model (TDM) component. Users with …
