    Abstract: A method is provided for controlling traffic management infrastructure, comprising: capturing images of vehicle license plates converting the images into license plate data including license plate characters; transmitting the license plate data to a central server having a data collection module, a data anonymization module, a data storage module and a data analysis module; extracting the license plate characters from the license plate data; packaging the license plate characters in license plate files; anonymizing the license plate files; storing, by the data storage module, the anonymized license plate files; analyzing the anonymized license plate file to identify a traffic condition; and outputting at least one command to at least one component of traffic management infrastructure, thereby causing the component to adjust an aspect of traffic management based upon the identified traffic condition.

    Abstract: Examples include a system for controlling traffic signalling devices at an intersection, including a first radar sensor that detects road users in a first detection region on a first traffic route, outputting first radar sensor data indicating first sensor detected positions and a first sensor detected radial velocities, and a second radar sensor that detects road users in a second detection region on a second traffic route, outputting second sensor data indicating second sensor detected positions and a second sensor detected velocities. The first radar sensor and second radar sensor are at different locations, or different orientations, or both, and configured such that the first and second detection region have an overlap. An electronic data processing device combines the first radar sensor data and second radar sensor data into combination signals, and controls the traffic signalling devices based at least partially on the combination signals.

    Abstract: In one example embodiment, a computer-implemented method for determining traffic conditions includes obtaining traffic sample data associated with a first direction of traffic on a first road segment, the traffic sample data including data indicative of a plurality of movement speeds associated with a plurality of objects. The method includes determining a plurality of average traffic speeds for the first direction of traffic on the first road segment based at least in part on the plurality of movement speeds. The method includes associating each of the plurality of average traffic speeds with at least one of a plurality of traffic types. The method includes determining map data based at least in part on the plurality of traffic types and associated average traffic speeds. The method includes transmitting to a client device in response to a request, map data corresponding to at least one of the plurality of traffic types.

    Abstract: A traffic control system for controlling traffic at a junction includes an intelligent traffic control agent. The intelligent traffic control agent is training using reinforcement learning, in a simulation model of the junction. The simulation model is calibrated and validated preferably using data from the same sensors which are used as inputs to the traffic control agent when deployed to control traffic at the junction.
