The purpose of this IEEE and Transit IDEA project was to develop and test a device to give rail transit personnel and train operators advance warning of dangers well in advance of entering the danger zones such as approaching train and other potential dangers such as Fire, Chemical, and Biological Releases. This device can provide a reliable way of giving the track worker; train operator and emergency responders a warning in enough time to avoid potential accidents, injuries, or death. Further this device cuts down on incident response time from the Operational Control Center to Command Center to provide additional security and eliminate lost response time. The information provided in this report will enable other rail rapid transit agencies the ability to consider using such devices to give early warning of approaching trains and other dangers to track workers, track walkers, track inspectors, emergency responders and signal personnel and also to give the train operator early warning of the presence of personnel in the track area as well as other dangers ahead.
