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)

FIG. 18 shows an exemplary periodic IRIS system check for system failure. When failure happens, the system fail handover mechanism is activated. First, failure is detected and the failed node is recognized. The functions of failed node are handed over to shadow system and success feedback is sent back to an upper level system if nothing goes wrong. Meanwhile, a failed system/subsystem is restarted and/or recovered from a most recent backup. If successful, feedback is reported to an upper level system. When the failure is addressed, the functions are migrated back to the original system.

Exemplary hardware and parameters that find use in embodiments of the present technology include, but are not limited to the following:

OBU:

a) Communication module Technical Specifications

    • Standard Conformance: IEEE 802.11p-2010
