Abstract:
This report of the Transportation Research Board presents information on the policies and operational characteristics of highway-rail grade crossing warning devices and details on system components, including advance warning times, train detection, and traffic signal interconnection. In addition, several advanced highway-rail grade crossing warning systems in operation are described. Information on highway traffic signal systems is presented, including traffic controller preemption system characteristics. The need for agency coordination on signal preemption is emphasized. Based on the survey of highway and rail agencies conducted for this synthesis, there appears to be a need to improve the compatibility between traffic operations at highway-rail grade crossings and traffic operations at signalized intersections in the vicinity of the crossing. This synthesis is an immediately useful document that records the practices that were acceptable within the limitations of the knowledge available at the time of its preparation. As the processes of advancement continue, new knowledge can be expected to be added to that now at hand.
