Samenvatting
From a study of protective device installations at rail-highway intersections, procedure is developed that establishes priorities for the improvement of safety at these intersections. Techniques are reported for computing installation and maintenance costs, prorated annually of rail-highway traffic control devices. In addition, the benefit cost relation-ship is demonstrated i.e. the intersections are ranked in descending order on the basis of the relation-ship between incremental benefits or the reduction in accident costs, and incremental cost of additional protection.
