... TCRP Web-Only Document 53 80 The repeated occurrence of a particular driver and/or pedestrian behavior could explain why a specific type of an incident or a crash would occur. As Chapter 3 reported in detail, there were 29 near-miss incidents reported by train operators at the 3 study intersections during the past 3 years.

Address any major volume changes through signal timing adjustments in order to avoid excessive queuing and subsequent blockage of the track which may increase the likelihood of a light rail vehicle/automobile conflict or crash.
