A synthetic image is produced which will be viewed by an operator of a train to provide the operator with important information indicative of the environment to be encountered by the train during subsequent movement of the train. This information includes information about upcoming track and highway crossings. The synthetic image may be utilized during all periods of operation of the train but will be particularly desirable during night and during periods of bad weather, such as rain, snow and fog, when normal vision is limited. The system utilizes accurate measurement of the location of the train, accurate knowledge of the path of the track and accurate knowledge of placement of track and highway crossings. Automated horn soundings, or monitoring of manual operator activations, significantly enhance safety at such track and highway crossings. |
