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.

In some embodiments, a data collection module collects data from vehicle installed external and internal sensors and monitors vehicle and human status, including but not limited to one or more of:
-
- a. Vehicle engine status;
- b. Vehicle speed;
- c. Surrounding objects detected by vehicles; and
- d. Human conditions.
In some embodiments, a vehicle control module is used to execute control instructions from an RSU for driving tasks such as, car following and lane changing.
In some embodiments, the sensing functions of an IRIS generate a comprehensive information at real-time, short-term, and long-term scale for transportation behavior prediction and management, planning and decision-making, vehicle control, and other functions. The information includes but is not limited to:
-
- a. Vehicle surrounding, such as: spacing, speed difference, obstacles, lane deviation;
- b. Weather, such as: weather conditions and pavement conditions;
