Abstract
Excellent guidance on the design of traffic signal preemption at highway intersections near highway-railroad grade crossings is provided by the ITE Recommended Practice Preemption of Traffic Signals At or Near Railroad Grade Crossings with Active Warning Devices and National Cooperative Highway Research Program Synthesis 271 Traffic Signal Operations Near Highway-Rail Grade Crossings.
