Impact of heavy vehicles on crossing safety: development of an adapted design tool

As part of a study commissioned by Transport Quebec aimed at evaluating the impact of heavy vehicles on the safety of railway crossings, we tested various classes of heavy vehicles to determine their acceleration and braking performances used in calculating sight triangles at railway crossings. After being applied in a mathematical model, the acceleration testing results were used to develop a railway crossings design and verification tool to be integrated into the RTD 10 standards, entitled "Road/Railway Grade Crossings: Technical Standards and Inspection, Testing and Maintenance Requirements". Recommendations were presented on integrating the tool into RTD 10, using uniform units of measure, removing fixed crossing reference times in RTD 10, and abolishing regulations restricting the shifting of gears while crossing railway tracks.
