The objective of this research was to provide an improved understanding of pedestrian-vehicle interaction at mid-block pedestrian crossings and develop methods that can be used in traffic operational analysis and microsimulation packages. Models describing driver yielding and pedestrian gap acceptance behaviour were developed from field data collected at 27 mid-block pedestrian crossings in three states (Alabama, Florida, and North Carolina), encompassing two different types of land use: university campuses and downtown areas. The project included an in-vehicle driver behaviour study with 15 drivers. This part of the data collection was performed in Florida and the results were used to develop nine simulation components describing various aspects of pedestrian-vehicle interaction. Specific outcomes for this research include: (a) a standalone model of pedestrian gap acceptance behaviour at unsignalised crossings, (b) a driver yielding behavioural model, (c) models describing vehicle dynamics and driver behaviour in advance of the crosswalk, (d) prototype algorithms incorporated and tested in a micro simulator, and (e) educational modules for dissemination of the research results. Key deliverables include the prototype algorithms implemented in simulation, a final report summarizing the research and findings, and educational modules on the research results that can be incorporated into university curricula, or serve as material for standalone professional development courses.
