What is claimed is: 
     
         1 . A virtual crossing system comprising:
 one or more networks;   a railroad information system,   a positioning and mapping system,   an alert receiving system, and   an integration system   wherein the integration system receives train information from the railroad system over the one or more networks and constructs a first digital zone around the train,   wherein the integration system receives location information from the alert receiving system over the one or more networks and constructs a second digital zone around the alert receiving device, and   wherein the integration system issues at least one of an alert, a notification, and a command depending on (i) when the first digital zone intersects the second digital zone or (ii) when the first digital zone is expected to intersect the second digital zone, according to defined parameters.
