Abstract:

This paper focuses on accident causation and countermeasures at arterial median light rail grade crossings. Unlike conventional railroad grade crossings, light rail systems often incorporate a grade crossing into an intersection environment. These complex intersections can be confusing to drivers and lead to a high proportion of accidents where drivers turn into or in front of an LRV traveling the same direction. It can be a matter of centimeters from the left turn lane to the right-of-way on the median trackage. In the case of side-running alignment and right turn accidents, there are often no turn lanes and drivers frequently neglect to use their turn signals. As a result, the light rail operators often lack sufficient warning time to respond to an illegal automobile movement.

Only a handful of literature has been published on this topic and we seek to synthesize accident causation literature from many fields as it relates to the median crossing. Although it is highly relevant to existing light rail systems, this paper should be of particular importance to the startup system still in the design phase.
