An intelligent intersection control system features an internal controller that receives digital messages containing detailed information items concerning, for example, the direction, speed, length and identity of a train. The controller generates appropriate commands that coordinate the functions of crossing safety devices. A controller is capable of receiving and using much more detailed train information than is possible with conventional warning systems. Railroad crossing warning features are capable of responding more flexibly to this more detailed train information. The controller also continuously adjusts the activation state for safety devices associated with the crossing. In particular embodiments, the control system provides and displays crossing status information including the amount of time remaining until a crossing is cleared of train traffic, the approach of a second train during blocking of the crossing by a first train, or a suggested alternate route for waiting road vehicles. The controller may also be used to actuate numerous standard crossing warning features, including crossing blocking arms, flashing lights, warning chimes and warning horns.
