Pedestrian and bicycle safety performance functions for segments and intersections
The objective of this research was to develop pedestrian and bicycle safety performance functions (SPFs) to better inform planning, design, and operations decisions. To accomplish this objective, three approaches to collecting data and developing pedestrian and bicycle SPFs for roadway segments and intersections were followed: *Using negative binomial regression analysis, pedestrian and bicycle SPFs were developed for urban and suburban roadway segments and intersections including exposure measures for motor vehicles, pedestrians, and bicycles and other geometric and traffic control elements. *Pedestrian and bicycle SPFs were developed by adapting crash prediction models used by the U.S. Road Assessment Program. *Regression models were developed to estimate the potential of a pedestrian or bicycle crash occurring in the absence of pedestrian or bicycle exposure data. The final pedestrian and bicycle SPFs were recommended for incorporation into the American Association of State Highway and Transportation Officials Highway Safety Manual.
