Objectives

The guidance in thisa report is intended to provide practitioners with useful information related to establishing safe crossings at roundabouts and channelized turn lanes (CTLs) for pedestrians who are blind. The specific objectives of this project were to:

• Identify and field test crossing treatments with the potential to enhance accessibility for pedestrians who are blind,
• Formulate and apply an evaluation framework and associated performance measures that can quantify accessibility,
• Develop approaches to extend the findings to other sites through statistical modeling and microsimulation, and
• Discuss implications of the results for engineering practice and the ongoing accessibility debate.

This report is not intended to provide practitioners with rigid requirements of when to install specific treatments. To do so would involve policy decisions that are beyond the scope of this effort. Instead, the report provides pertinent information on the concept of accessibility and how to provide improved crossing environments based on the crossing task for a visually impaired pedestrian.
