WSTIP provided detailed information for the most severe crash that involved a fixed-route transit bus whose driver passed out from an apparent heart attack in March 1999.
The following is a summary of WSTIP database findings:
The WSTIP database provided valuable information on wheelchair riders, although the cases occurred aboard paratransit vans and not transit buses.
A more recent study reported that wheelchair riders account for 3 to 10 percent of passenger incidents , while comprising only 0.24 percent of the general ridership (WSTIP analysis).
