Among other things, we describe techniques for traffic light estimation using range sensors. A planning circuit of a vehicle traveling on a first drivable region that forms an intersection with a second drivable region receives information sensed by a range sensor of the vehicle. The information represents a movement state of an object through the intersection. A traffic signal at the intersection controls movement of objects through the intersection. The planning circuit determines a state of the traffic signal at the intersection based, in part, on the received information. A control circuit controls an operation of the vehicle based, in part, on the state of the traffic signal at the intersection.

A safety system to prevent a wrong-way vehicle from entering a roadway by driving onto an exit ramp in the wrong direction. A detection system monitors and detects the wrong-way vehicle as soon as it enters the exit ramp in the wrong direction. Upon detecting a wrong-way vehicle, the roadway safety system remotely sends a signal to turn off the motor of the wrong-way vehicle. The system may also record the vehicle's identification and communicate it to a command center to determine the mobile phone number of the owner/driver and call the driver to alert them that they are driving the wrong-way. Alternatively, a series of one or more penetrable and/or impenetrable barriers could be deployed to stop the wrong-way vehicle. The safety system may further include a communications system to communicate to a central office to initiate other alarms and control traffic on the roadway in response to detecting a wrong-way vehicle.

A traffic metering system for metering access to at least one metered segment, configured to receive requests from one or more vehicles announcing a destination and a requested arrival time, and to authorize the vehicles to enter a metered segment based on a schedule for the at least one metered segment. Vehicles configured for use in the metering network announce a request for destination and arrival time to the metering network and the metering network authorizes the vehicle to enter the metered segment based on a schedule for the at least one metered segment.

According to the present invention, there is provided an information processing apparatus (30) of a second administrator, the apparatus including: a first obtainment unit (31) that obtains first information collected by a first information collection apparatus installed over a first road managed by a first administrator; a second obtainment unit (32) that obtains second information collected by a second information collection apparatus installed over a second road managed by the second administrator; and a notification unit (33) that notifies the first administrator of at least one of the first information and information detected on the basis of the first information.

The technology provides designs and methods for the transit management system, which facilitates transit vehicle operations and control for connected automated transit vehicles (CATVs) systems. The transit management system provides transit vehicles with customized/non-customized information and time-sensitive control instructions for transit vehicle to fulfill the driving tasks such as vehicle routing, lane changing, turning. The transit management system also realizes transit vehicle lane design, transportation operations and management services for transit vehicle. The transit management system consists of one of more of the following physical subsystems: (1) Roadside Unit (RSU) network, (2) Traffic Control Unit (TCU) and Traffic Control Center (TCC) network, (3) Vehicle Onboard Unit (OBU), (4) Traffic Operations Centers (TOCs), (5) Cloud platform. The transit management system realizes one or more of the following function categories: sensing, transportation behavior prediction and management, planning and decision making, and vehicle control. The transit management system is supported by road infrastructure, real-time wired and/or wireless communication, the power supply networks, and cyber safety and security services.

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.

A highway system including: a stretch of highway that includes one or more lanes, and each lane being divided into a plurality of fixed size slots; a plurality of vehicles traveling on the highway at a system specified speed; and a control system configured to control the plurality of vehicles by sending commands to the plurality of vehicles via a wireless communication system; wherein the control system is configured to divide time into timeslots based on the system specified speed and the size of the slots, such that each vehicle is assigned to occupy a slot during a timeslot; wherein each of the plurality of vehicles includes a processor configured to receive a command from the control system and to control its associated vehicle according to the command.

The disclosure relates to a driver assistance system for a motor vehicle. The driver assistance system includes a wrong-way driving detection device that detects underway or imminent wrong-way driving of the motor vehicle. The driver assistance system also includes an output device that outputs a signal to a driver of the motor vehicle indicative of a wrong-way driving detection. The driver assistance system, via the output device, is configured to modify an operating state of the infotainment device according to the wrong-way driving detection.
