SYSTEM FOR GRADE CROSSING ACCIDENT MITIGATION
First Claim
1. A method for accident mitigation at a grade crossing of a railway and a highway, comprising:
- when desired to prevent a vehicle from entering the grade crossing, moving at least one gate horizontally to block the highway; and
when desired to permit said vehicle to enter and pass through the grade crossing, moving said at least one gate horizontally to unblock the highway and instead guard the railway such that said vehicle cannot exit the grade crossing onto the railway without impacting a said gate.

Abstract
A method, apparatus, and system for accident mitigation at a grade crossing of a railway and a highway. One or more gates are selectively horizontally movable to block the highway such that vehicles are blocked from entering the grade crossing, or alternately movable to unblock the highway yet concurrently then block vehicles from exiting the grade crossing onto the railway without impacting at least one gate. Alternately, one or more highway-gates are selectively vertically movable to block or unblock the highway and one or more railway-gates are vertically movable to guard or unguard the railway such that a vehicle cannot exit the grade crossing onto the railway without impacting a railway-gate.

8. A system for accident mitigation at a grade crossing of a railway and a highway, comprising:
-
at least one gate means to selectively horizontally move to block the highway when it is desired to prevent a vehicle from entering the grade crossing; and
said at least one gate means further to horizontally move to unblock the highway and instead blockably guard the railway such that said vehicle cannot exit the grade crossing onto the railway without impacting a said gate.

9. A method for accident mitigation at a grade crossing of a railway and a highway, comprising:
-
when desired to prevent a vehicle from entering the grade crossing, moving at least one highway-gate vertically to block the highway such that said vehicle cannot enter the grade crossing and, essentially contemporaneously, moving at least one railway-gate vertically to unblock the railway such that a train can enter and pass through the grade crossing; and
when desired to permit said vehicle to pass through the grade crossing, moving said at least one said highway-gate vertically to unblock the highway such that said vehicle can enter and pass through the grade crossing and, essentially contemporaneously, moving said at least one said railway-gate vertically to blockably guard the railway such that a said vehicle cannot exit the grade crossing onto the railway without impacting a said railway-gate. - View Dependent Claims (10)

11. An apparatus for accident mitigation at a grade crossing of a railway and a highway, comprising:
-
at least one highway-gate that is selectively vertically movable to block the highway such that said vehicle thereon is blocked from entering the grade crossing and alternately to unblock the highway such that said vehicle is permitted to enter and pass through the grade crossing; and
at least one railway-gate that is selectively vertically movable to unblock the railway such that a train can enter and pass through the grade crossing and alternately to blockably guard the railway such that a said vehicle cannot exit the grade crossing onto the railway without impacting a said railway-gate. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A system for accident mitigation at a grade crossing of a railway and a highway, comprising:
-
at least one highway-gate means to selectively vertically move to block the highway when it is desired to prevent a vehicle from entering the grade crossing and to vertically move to unblock the highway when it is desired to permit said vehicle to enter and pass through the grade crossing; and
at least one railway-gate means to selectively vertically move to blockably guard the railway such that said vehicle cannot exit the grade crossing onto the railway without impacting a said railway-gate.
