Rail-Highway Grade Crossings: Multi-Vehicle Accelerometer-Based Rideability Measures

Unlike highways, no widely accepted quantitative method exists to assess the rideability of rail-highway grade crossings. Conventional qualitative judgment-based inspection can be subjective. Therefore, a quantitative method is desirable for objective prioritization of repair, rehabilitation or reconstruction. Previously, an acceleration-based metric was proposed and tested for a single vehicle at one crossing. This paper reports accelerometer-based testing for selected vehicles at various crossings to assess the effect of vehicle type on rideability measurements. Maximum positive and negative accelerations at different speeds are recorded, as well acceleration profiles and a proxy measure for total energy dissipated, root mean square (RMS) of accelerations. The ability to use a single “test” vehicle to predict the rideability experienced by other vehicle types is also demonstrated.
