Modelling risk at low-exposure railway level crossings: supporting an argument for low-cost level crossing warning devices with lower levels of safety integrity
This paper describes a risk model for estimating the likelihood of collisions at low-exposure railway level crossings, demonstrating the effect that differences in safety integrity can have on the likelihood of a collision. The model facilitates the comparison of safety benefits between level crossings with passive controls (stop or give-way signs) and level crossings that have been hypothetically upgraded with conventional or low-cost warning devices. The scenario presented illustrates how treatment of a cross-section of level crossings with low-cost devices can provide a greater safety benefit compared with treatment with conventional warning devices for the same budget.
