Abstract
TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2377 consists of nine papers that explore the Midwest guardrail system; opposite-direction road departure crashes; the injury risk posed by side impact of nontracking vehicles into guardrails; retrofit bridge rail design and testing; limitations of the Highway Safety Manual to predict run-off-road crashes; crash wall design to protect mechanically stabilized earth retaining walls; the implementation of nonproprietary w-beam guardrail trailing-end terminals; guardrail-to-bridge rail transition; and motorcyclist impacts into roadside barriers.
