Every year, scores of pedestrians and bicyclists are killed or injured in collisions with motor vehicles, exacting a terrible toll on individuals, families, businesses, and communities throughout the country. To respond to this national problem, the transportation community continues to develop innovative approaches to enhance the capacity of State and local coordinators, planners, and engineers to address traffic fatalities and injuries. The Pedestrian and Bicycle Crash Analysis Tool (PBCAT): Version 2.0 offers a dynamic and practical method for recording vital information about pedestrian and bicyclist crashes to produce diverse and useful reports. PBCAT also gives access to engineering, education, and enforcement countermeasures that represent promising procedures for mitigating crashes. The details PBCAT captures about crashes between motor vehicles and pedestrians or bicyclists, and the resources it presents, will further efforts of agencies nationwide to identify and select appropriate practices to improve pedestrian and bicyclist safety.

16. Abstract In 2004, 4,641 pedestrians and 725 bicyclists were killed, accounting for 13 percent of all traffic fatalities in the United States. An additional 68,000 pedestrians and 41,000 bicyclists were reported to be injured as a result of collisions with motor vehicles. PBCAT is a software product intended to assist State and local pedestrian and bicycle coordinators, planners, and engineers in addressing pedestrian and bicyclist crash problems. PBCAT accomplishes this goal through the development and analysis of a database containing details associated with crashes between motor vehicles and pedestrians or bicyclists. One of these details is the crash type, which describes the pre-crash actions of the parties involved. With the database developed, the software can then be used to produce reports and select countermeasures to address the problems identified. Features of PBCAT Version 2.0 include:
