The Active Transportation Return on Investment (ATROI) study aims to provide a quantitative and qualitative assessment of the benefits of active transportation infrastructure in the Portland, OR region. The study uses a selection of AT projects constructed in the region between 2001 and 2017 to evaluate impacts, with a focus on economic impacts, broadly defined. Two types of projects are included. 2040 catalyst projects retrofitted busy commercial streets with pedestrian friendly treatments aimed at catalyzing economic development. Longer gap-filling projects completed key routes within the regional bicycling network with the potential to increase the bicycle mode share.

The scope of the project has three main tasks.

1. A technical analysis of 2040 catalyst projects provided quantitative estimates of the economic impacts of the catalyst projects, including such things as jobs, sales, and property values. This report focuses on this task, conducted by Transportation Research and Education Center (TREC) at Portland State University (PSU).

2. A technical analysis of longer gap-filling bikeways provided quantitative estimates the benefits of these projects to users, including travel time savings and health benefits. This task was conducted by staff at Metro and results are not included here.

3. A qualitative assessment aimed to supplement the quantitative analysis of Tasks 1 and 2 with qualitative information that helps tell the story of each project. The results of this task, conducted by TREC at PSU, are in a separate report.
