Public transit systems are often accepted as energy and environmental improvements to automobile travel, however, few life cycle assessments exist to understand the effects of implementation of transit policy decisions. To better inform decision-makers, this project evaluates the decision to construct and operate public transportation systems and the expected energy and environmental benefits over continued automobile use. The public transit systems are selected based on screening criteria.

- This working paper is intended to provide the preliminary methodology and results used to assess the life-cycle energy consumption and air emission effects of Los Angele Metro’s Orange bus rapid transit and Gold light rail transit lines for upcoming reports, press releases, and peer-reviewed journal publication. The methodology and results are subject to future updates during the peer-review process as we incorporate feedback. Before using the information in this working paper the reader is strongly advised to contact the authors for notification of the release of our final results, and for a listing of related material.
