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(shuō)明書(shū)

  • ii. Mobile platforms, including but not limited to: cars and trucks, unmanned aerial vehicles (UAVs), for short-term or flexible deployment.

    • In some embodiments, RSUs are deployed on special locations and time periods that require additional system coverage, and RSU configurations may vary. The special locations include, but are not limited to:

      • a. Construction zones;
      • b. Special events, such as sports games, street fairs, block parties, concerts; and
      • c. Special weather conditions such as storms, heavy snow.

    In some embodiments, the TCCs and TCUs, along with the RSUs, may have a hierarchical structure including, but not limited to:

      • a. Traffic Control Center (TCC) realizes comprehensive traffic operations optimization, data processing and archiving functionality, and provides human operations interfaces. A TCC, based on the coverage area, may be further classified as macroscopic TCC, regional TCC, and corridor TCC;
      • b. Traffic Control Unit (TCU), realizes real-time vehicle control and data processing functionality, that are highly automated based on preinstalled algorithms. A TCU may be further classified as Segment TCU and point TCUs based on coverage areas; and
