Side Object Detection Systems Evaluation : Final Evaluation Report - Report on the results of an independent evaluation of a Side Object Detection System (SODS) for transit buses. The FTA worked with an evaluator and three transit agencies that use the system to address three key goals: 1) to assess operator usability and acceptance of SODS, 2) to assess the return on investment (ROI) of SODS, and 3) to identify lessons learned and other information that would be useful to agencies considering deployment of SODS or similar technologies in the future.
