There is provided a decentralized system and method for distributed traffic management comprising: a plurality of intersection computing agents connected across a communication network, each intersection computing agent located at a particular intersection communicating with a plurality of corresponding local link computing agents comprising sensors located on each respective road link directly connected to the particular intersection, to receive a link status report comprising speed and number of vehicles on said each respective road link; and said each intersection computing agent calculating an estimated travel time for said each respective road link from said link status report and receiving link information packet comprising the estimated travel time for said each respective road link from a first plurality of intersection computing agents located at a first plurality of intersections physically located downstream to create a network travel time matrix for routing vehicles at said particular intersection.

[Solving Means] A traffic control device according to an embodiment of the present invention is a traffic control device that controls a traffic light installed on a route of a vehicle running on the basis of an operation diagram, including: an acquisition unit; a determination unit; and a signal generation unit. The acquisition unit acquires, from the vehicle, vehicle information including information regarding the operation diagram and a current position of the vehicle. The determination unit calculates, on the basis of the vehicle information, an estimated time of arrival at the traffic light, and determines whether or not the estimated time is on a scheduled time. The signal generation unit generates, where it is determined that the estimated time is delayed from the scheduled time, a control signal for causing the traffic light to execute signal control for preferentially causing the vehicle to pass therethrough.

Aspects of the present disclosure include methods, systems, and non-transitory computer readable media for receiving a plurality of images of a plurality of street locations from a plurality of image capturing devices, identifying an event at a street location of the plurality of street locations based on one or more of the plurality of images, determining at least one new route for at least one vehicle based on the event and one or more of the plurality of images, and transmitting at least one indication indicating the at least one new route to at least one receiving device.

The present disclosure includes apparatuses, methods, and systems for secure communication in a traffic control network. An embodiment includes a memory, and circuitry configured to receive a traffic control public key from a traffic control device, wherein the traffic control public key is received in response to providing, to the traffic control device, a request to modify content of the traffic control device, encrypt data corresponding to vehicle information using the traffic control public key, provide, to the traffic control device, the encrypted data to store the data in the traffic control device, and access a network of traffic control devices, including the traffic control device, via the data stored in the traffic control device.

Method for controlling the light distribution of a traffic route luminaire (1) in a network of luminaires, which is preferably also organized as a mesh network. The luminaire has a luminaire head having a settable light module and a controller, the light distribution of the luminaire being variable. The luminaire communicates luminaire data to at least one server, the luminaire data being luminaire-specific and including the installation location of the luminaire. The method comprises the steps of: —automatically allocating a light distribution to the luminaire (1) in accordance with the communicated luminaire data; —automatically setting the light module on the basis of the allocated light distribution; and determining, by said at least one server, a light distribution class of the traffic route luminaire on the basis of a traffic route topology (2,3,4,5,6).

A traffic control device (TCD) is described for managing control of multiple right of way passages at a traffic intersection. The TCD includes a mobile wireless interface for communicating with an in-vehicle mobile wireless device (IV-MWD) to receive a commuter profile (CP) containing a subscribed switch time interval (SSTI). The TCD determines a set of passage priority values for respective ones of a set of controlled right of way passages. The TCD selects, based upon the set of passage priority values, a highest priority one of the set of controlled right of way passages as a next controlled right of way passage granted passage. The TCD resets a timer duration value associated with a next controlled right of way passage period, executes a right of way passage switch. Thereafter, the TCD maintains a current switch status of the traffic control device for a period corresponding to the timer duration value.

A system and method are provided for connecting intersections, to enable two-way wireless communication between a cloud-based traffic operations service and new and existing traffic cabinet hardware using “connected intersection” technology. By providing hardware in existing (or new) traffic control cabinets that can communicate wirelessly with a cloud-based traffic operations system, customers can enhance and upgrade legacy traffic networks using existing IT infrastructure (i.e. servers, hard drives, etc.) or existing communication networks. The connected intersection technology further provides software functionalities including real-time alerts, connectivity between existing cabinets and central systems, and signal timing-plan management for customers that lack an existing central system.
