Abstract: Certain embodiments provide a crossing bar system. The crossing bar system may include a rotatable drive shaft, a motor, a triangular crossing bar tube, and a vehicle body bar restraint. The motor is coupleable to an end of a vehicle and is operable to rotate the rotatable drive shaft. The triangular crossing bar tube is coupled to and extends substantially horizontally from the rotatable drive shaft. The triangular crossing bar tube may include lighting. The vehicle body bar restraint is coupleable to the end of the vehicle. The triangular crossing bar tube is deployable between a retracted position where the triangular crossing bar tube is substantially parallel to the end of the vehicle and may be received within the restraint, and a deployed position where the triangular crossing bar tube is substantially perpendicular to the end of the vehicle.

Abstract: A stop-arm with camera system for a vehicle is provided. The stop-arm with camera system may include a shield, a stop-arm, and a camera assembly. The stop-arm includes a first side and a second side. The stop-arm may be deployable between a first position where the first side of the stop-arm is disposed at least partially inside the shield, and a second position where the stop-arm is substantially perpendicular to the shield. The camera assembly is coupled to the first side of the stop-arm. The stop-arm with camera system may be mounted on a rear passenger side of the vehicle, which may be a bus. The camera assembly may provide a view including an area that is under the vehicle and between a rear wheel of the vehicle and a front wheel of the vehicle when the stop-arm is in the second position.
