摘要

The invention provides systems and methods for an Intelligent Road Infrastructure System (IRIS), which facilitates vehicle operations and control for connected automated vehicle highway (CAVH) systems. IRIS systems and methods provide vehicles with individually customized information and real-time control instructions for vehicle to fulfill the driving tasks such as car following, lane changing, and route guidance. IRIS systems and methods also manage transportation operations and management services for both freeways and urban arterials. In some embodiments, the IRIS comprises or 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), and (5) cloud information and computing services. The IRIS manages one or more of the following function categories: sensing, transportation behavior prediction and management, planning and decision making, and vehicle control. IRIS is supported by real-time wired and/or wireless communication, power supply networks, and cyber safety and security services.

說明書

  • Process Object detection using Data from the sensing module and other necessary regular calculation (e.g., Low power fully custom ARM/X86 based processor)
  • AI processing Unit
    • Machine learning
    • Decision making/planning and prediction processing

    • c) an interface Module:

      • FPGA based Interface unit
      • FPGA processor that acts like a bridge between the AI processors and the External Object Calculating Module processors and send instructions to the communication modules
        The RSU Deployment

    a. Deployment location

      • The RSU deployment is based on function requirement and road type. An RSU is used for sensing, communicating, and controlling vehicles on the roadway to provide automation. Since the LIDAR and other sensors (like loop detectors) need different special location, some of them can be installed separately from the core processor of RSU.

    Two exemplary types of RSU location deployment type:
