A radar monitoring system and a radar monitoring method for monitoring a traffic control zone involve installing two radars near the traffic control zone so that the radars emit radar waves covering the traffic control zone and serve as backups for each other; locating any object in the traffic control zone as a coordinate point with respect to a set of X and Y coordinate axes, and subjecting the X and Y coordinate axes of the two radars to axial normalization, so that an identical object in the traffic control zone is located by the first radar and the second radar at approximately the same coordinate point. An alert area is defined in the traffic control zone and an excluded area around a resident facility in the traffic control zone is excluded from the alert area. When an object in the alert area is determined as an obstacle, an alert is triggered.

This disclosure is generally directed to systems and methods for determining a passage status of a train through a railroad crossing. In an example method, a railroad crossing status detector system provided in a vehicle may determine that a train is approaching the railroad crossing. The determination is made by evaluating a first detection signal received from a first train detection apparatus located on one side of the railroad crossing. The railroad crossing status detector system may then evaluate a second detection signal received from a second train detection apparatus located on the other side of the railroad crossing and determine that the train has traveled past the railroad crossing. The system may also evaluate one or both detection signals to determine whether the train is currently located at the railroad crossing or is backing up after traveling at least partway across the railroad crossing.

A people count estimation apparatus includes an information management unit configured to at least manage road network data which is spatial information data regarding a road network formed to include a plurality of observation points and a road connecting the observation points, an observation point list which is a list of the observation points, and the numbers of people passing per unit time at the observation points in each direction of the road, a coefficient calculation unit configured to identify, from the observation point list, a first observation point where the number of people passing in each direction is not measured among the plurality of observation points, identify a second observation point where the number of people passing in each direction is measurable and which is connected to the first observation point by the road among the plurality of observation points, and calculate a weight that an observation value per time period at the second observation point contributes to the number of people passing in each direction at the first observation point, and an estimation unit configured to estimate the number of people passing in each direction at the first observation point using the weight, the observation value at the second observation point, and data regarding a people count observed at the first observation point.

A system comprises a set of sensors on a first end of a vehicle having the first end and a second end, and a controller. The sensors are configured to generate corresponding sensor data based on a detected object along a direction of movement of the vehicle. The controller is configured to compare a time at which the first sensor detected the object with a time at which the second sensor detected the object to identify the first end or the second end as a leading end of the vehicle, and to calculate a position of the leading end of the vehicle based on the sensor data generated by one or more of the first sensor or the second sensor. The controller is also configured to generate a map of the plurality of objects based on the sensor data.

A monitoring device includes a progress execution unit that causes a combination of an irradiation unit and a light reception unit to progress inside a space that is tubular inside, the irradiation unit being for irradiating, with laser light, an exposed object that is an object exposed in the space of a tubular object being an object having the space, the light reception unit converting return light of the laser light from the exposed object into an electric signal; and a section specification unit that specifies, based on the electric signal, a predetermined-state section position being a position of a predetermined-state section that is, among sections of the exposed object that are irradiated with the laser light, the section indicating a predetermined state, and outputs the resultant.

An optical system including one or more optical sensors and a processing unit capable of performing built-in tests of the optical sensor(s) and methods thereof are disclosed. The processing unit includes a built-in test module configured to detect a reduction of an optical quality of at least some of the images generated by at least one of the optical sensors with respect to an expected optical quality thereof. The built-in test module may be configured to determine whether the reduction of the optical quality thereof is due to the “external optical disturbances” (EOD) and/or failure of the optical sensor(s)/system. The processing unit may include a relative built-in test module configured to compare at least some images generated by at least two of the optical sensor(s) and to determine which of the at least two optical sensors thereof, if any, is subjected to at least one of the EOD and/or failure.

A system is provided that may include a controller having one or more processors. The one or more processors may control movement of a vehicle system along a route, and determine a restriction in speed of the vehicle system at a switch point. The one or more processors may determine a direction of movement of the vehicle system based on the restriction in the speed at the switch point.

Methods and systems for managing a speed of a vehicle are provided. The methods and systems obtain image data from one or more vision sensors disposed onboard a vehicle. A stopping distance of the vehicle is determined based at least in part on the image data. A moving speed of the vehicle and a speed limit of the vehicle are determined. The speed limit is determined based on the stopping distance that is determined from the image data. The methods and systems control movement of the vehicle based on a difference between the moving speed of the vehicle and the speed limit of the vehicle.

An alert area is defined in the traffic control zone and an excluded area around a resident facility in the traffic control zone is excluded from the alert area. When an object in the alert area is determined as an obstacle, an alert is triggered.
