Abstract: An intersection management system and method for reducing or avoiding potential collisions between vehicles are provided. The system may use a wireless signal, with or without a circuit, to traverse an intersection. The system may use, at least in part, a positive vehicle control system.

Abstract: Systems and methods for detecting or predicting potential collisions between vehicles are provided. The systems and methods may receive sensor output indicative of a location, a heading, and/or a moving speed of a first vehicle and/or a second vehicle. The systems and methods may predict a collision between the vehicles at an intersection between routes based on the received sensor output. The systems and methods may change movement of the first vehicle and/or the second vehicle responsive to predicting the collision.

Abstract: A system includes one or more processors. The one or more processors are configured to receive crossing obstruction information from an optical sensor disposed proximate a crossing of a route traversed by a vehicle, with the crossing obstruction information indicating a presence of an obstruction to the crossing; obtain position information indicating a position of the vehicle traversing the route; determine proximity information of the vehicle indicating proximity of the vehicle to the crossing using the position information; determine a presence or absence of an alert state indicating a potential of the crossing being obstructed using the crossing obstruction information and the proximity information; and perform a responsive activity based responsive to a determination of the presence of the alert state.

Abstract: An obstruction detection system receives sensor data from sensor assemblies at different crossings of routes on which vehicles travel. The system determines whether an obstruction is present in one or more of the crossings based on the sensor data. The system wirelessly restricts movement of one or more vehicles responsive to determining that the obstruction is present by wirelessly communicating a notification signal to the one or more vehicles.
