DATA COLLECTION METHODOLOGY
Pedestrian Behavior Data
Data were collected in White Plains during the week of September 20, 2004. At each intersection,
Portable Archival Traffic History (PATH) cameras were deployed for one full day of recording for
one minor leg and one major leg. PATH systems record pedestrian activity at the intersection
without interfering with pedestrians. The pedestrian behavior data were collected without any major
difficulties.
Surveys
The project team developed a brief survey to be administered to pedestrians at the study
intersections. The purpose of the survey was to gauge pedestrian understanding and preference for
PCD signals and TPS.
Survey administration took approximately 1 minute. Surveys were administered at the two PCD study
intersections to pedestrians who had completed their crossing at the intersections. The targets of the
survey were pedestrians over 18 years of age.
The survey response was much lower than anticipated, particularly for older pedestrians.
Approximately 90 percent of the people who were approached regarding the survey declined to
participate.
