摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for monitoring vehicles traversing a dedicated roadway that includes an at-grade crossing. In some implementations, a system includes a central server, a gate system, and sensors. The gate system provides access to an at-grade crossing for vehicles. The sensors are positioned in a fixed location relative to a roadway, the roadway including the at-grade crossing. Each sensor can detect vehicles on the roadway. For each vehicle, each sensor can generate sensor data and observational data from the generated sensor data. Each sensor can determine a likelihood that the detected vehicle will approach the at-grade crossing by comparing the likelihood to a threshold. In response, each sensor can transmit data to the gate system that causes the gate system to allow the autonomous vehicle access to the at-grade crossing prior to the autonomous vehicle reaching the gate system.

摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for allowing vehicles access or egress from a dedicated roadway. In some implementations, a system includes a server, an interface, and sensors. The interface receives data from a railroad system that manages a railroad running parallel to a first roadway. The sensors are positioned in a location relative to the first and second roadway. Each sensor can detect vehicles on the second roadway. For each detected vehicle, each sensor can generate first sensor data based on the detected vehicle and the data received at the interface. Second sensor data can be generated based on activities on the first roadway. Observational data can be generated based on the first and second sensor data. An instruction can be determined to allow the detected vehicle access to the first roadway. The instruction can be transmitted to the detected vehicle.

摘要： A crossing gate mechanism includes a swingable gate arm, a rotatable gate arm shaft fixed to the gate arm, and an electronic sensor assembly coupled to the gate arm shaft. Rotation of the gate arm shaft corresponds with swinging of the gate arm. The electronic sensor assembly senses an angular position of the gate arm shaft and transmits a position signal corresponding thereto. The electronic sensor assembly includes a driving element that is attached to the gate arm shaft to rotate therewith. the electronic sensor assembly also includes a driven element that is driven by the driving element such that rotation of the gate arm shaft causes the driven element to rotate. The electronic sensor assembly is configured to generate the position signal based on a position of the gate arm shaft.

摘要： A control system may be provided that may include one or more processors. The one or more processors may be configured to receive obstruction information related to a defined area from at least one optical sensor, determine an obstruction is in the defined area based on the obstruction information in response to actuation of a first safety device that is configured to prevent the obstruction from entering the defined area, and communicate an actuation signal to a second safety device to control movement of the second safety device based on the obstruction determined to be in the defined area.

摘要： A gate retraction device is provided to return a crossing gate arm to a home position. The gate retraction device comprises a frame to hold a gate pivot pin that is configured to provide a bi-directional rotation of the crossing gate arm. The gate retraction device further comprises a main pivot assembly that receives the gate pivot pin on one end so as to enable rotation of the main pivot assembly in a horizontal plane. The main pivot assembly comprises a first side and a second side opposite of the first side and wherein the main pivot assembly further comprises a spring pin extending on the first side and the second side of the main pivot assembly. The gate retraction device further comprises a spring-loaded assembly trapped against the spring pin of the main pivot assembly as the main pivot assembly rotates.

摘要： An apparatus for use with a railway safety system having a circuit for enabling and disabling a safety device when trains are approaching or within a railway crossing. The apparatus may include an override switch, a flag, and a light, and may generate a control signal received by and configured to override the safety device circuit. The flag and the light may indicate to approaching trains that the safety device of the railway safety system has been overridden.
