... After this initial overview, the chapter explores the major categories of root causes and contributing factors for collisions on LRT alignments, as suggested by the literature, the survey, the data analysis, the transit agency consultations, and the site visits. Such information can help practitioners understand their safety issues and identify how their concerns align with those of other systems.

... Studying LRT Safety Issues and Treatments Most previous studies of safety along LRT alignments have examined treatments using simple before-and-after comparisons of collisions, anecdotal evidence, collision surrogate measures such as violations, or a combination of two or three of these approaches. Standard "t" tests require sufficiently long periods to elapse both before and after studies.

... Surrogate measures described by the LRT agencies consulted by the project team include: • Operator reports of near misses or other significant safetyrelated events. • Risky behavior: – Metro Transit in Minneapolis conducted a series of pedestrian violation counts at a downtown station.

... None of the second train warning signs viewed during the site visits to transit agencies indicated the direction of the approaching train. The impacts of providing this additional information should be tested using before-and-after surrogate measures such as risky actions by pedestrians or emergency brake records at a crossing where a directional second train warning sign is installed.
