Real-time vehicle spacing control

A non-transitory computer readable medium including instructions that when executed are operable to:

• receive current locations of a plurality of mobile devices currently on a route;
• determine a relative distance between a first mobile device of the plurality of mobile devices and at least a second mobile device of the plurality of mobile devices as a function of the received current locations;
• and
• generate an action signal for operation of a at least one vehicle associated with one of the plurality of mobile devices based on the determined relative distance.

An apparatus comprising:

• a communications interface configured to receive data indicative of a calculated relative distance between a first vehicle of a plurality of vehicles traveling along a route and at least a second vehicle of the plurality of vehicles traveling along the route;
• position circuitry configured to determine the current location of the apparatus;
• a controller configured to generate an action signal for operation of the first vehicle or the second vehicle based on the calculated relative distance and the current location;
• and
• an output interface configured to present the action signal for the operation of the first vehicle or the second vehicle.
