CR Associates prepared the City of San Diego Pedestrian Crosswalk Guidelines, which provides a systematic approach to assessing varying roadway locations for the potential installation of marked crosswalks and additional pedestrian safety and traffic calming treatments.  The analysis of 14 years of pedestrian collision data and the creation of a pedestrian risk model informed the development of an uncontrolled crossing location warrant system, crossing treatment thresholds, and crossing treatment option tables.  In addition to identifying potential infrastructural improvements, the Pedestrian Crosswalk Guidelines outlines sample programs to help improve safety, including education, awareness and encouragement, and enforcement programs. The project resulted in an update to Council Policy 200-07, previously adopted in 1990.  CR Associates and sub-consultant SafeTREC received the Excellence in Safety Research for Active Living at the 2015 Active Living Research national conference for our work on this project.
