|PBCAT: what is it?
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. The Pedestrian & Bicycle
Crash Analysis Tool (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.
Why Crash Typing
The development of effective countermeasures to help prevent bicyclist
and pedestrian crashes is hindered by insufficient detail on computerized
state crash files. Analysis of these data can provide information on where
pedestrian and bicyclist crashes occur (city, street, intersection, two-lane
road, etc.), when they occur (time of day, day of week, etc.), and characteristics
of the victims involved (age, gender, injury severity, etc.). These data
cannot provide a sufficient level of detail regarding the sequence of events
leading to the crash.
In the 1970s, methods for typing pedestrian and bicycle crashes
were developed by the National Highway Traffic Safety Administration to
better define the sequence of events and precipitating actions leading to
bicycle- and pedestrian-motor vehicle crashes. In the 1990s, the methodologies
were applied to over 8,000 pedestrian and bicycle crashes from six States.
The results provided a representative summary of the distribution of crash
types experienced by pedestrians and bicyclists. This method has evolved
over time and was refined during development version 1.0 of PBCAT.
