Samenvatting
The papers in this volume address three distinct topics: bicycling, pedestrians, and older drivers. Within each area a diversity of technical topics is covered. Accident data requirements for increasing the understanding of bicyling accidents are put forth, an environmental benefits analysis of bicycling and walking is given, and clearance intervals at signalized intersections for mixed traffic are analyzed. An intelligent bicycle routing system to supply cyclists with important travel information and a study of bicyclist characteristics in Phoenix round out the section on bicycles and bicycle facilities. A similar variety of subjects is found aming the papers on pedestrians: a method for determining service levels is described.
