2296 Highway/Rail Intersection Hump or High-Profile Crossings Problems

Hump or high-profile crossings are intersections where the road surface profile across the rail tracks presents a potential risk for low-clearance vehicles getting stuck. These crossings pose a particular challenge for certain vehicle types, including those with low-clearances, long-wheelbases, or long-overhangs, as they are prone to becoming high-centered or "hung-up" on highway-rail grade crossings (HRGCs). The proposed project aims to address hang-up problems of low-clearance vehicles on highway-rail grade crossings. The objectives include assessing the magnitude of the problem, developing an effective process to identify and evaluate crossings with hang-up issues, and providing recommendations for safe crossings for trucks and buses. Key requirements for hang-ups are high-profile vertical alignment or sharp grade breaks and low ground clearance with long-wheelbase or overhang vehicles. The project outlines several sub-objectives: Review literature on highway/rail intersections and high-profile crossing hang-up problems. Determine the extent of hang-ups and accidents involving low-clearance vehicles at grade crossings. Develop a procedure to identify suspect crossings with hang-up potentials. Propose, test, compare, and recommend field measuring approaches to obtain 3D ground profiles at railroad crossings.
