Abstract

The technology provides systems and methods for a system providing customized and route-specific operations, control, and services for connected and automated vehicles (CAVs) according to user origin and destination requests, based on connected automated vehicle highway (CAVH) systems which includes an intelligent road infrastructure system providing transportation management and operations and individual vehicle control for CAV.

First claim

We claim:

1. A system providing customized and route-specific operations, vehicle control, and services for connected and automated vehicles (CAV) according to user origin and destination requests, said system comprising the following components:
a) a network of roadside units (RSUs) comprising RSUs residing in road infrastructure;
b) vehicle onboard units (OBU) and vehicle interfaces residing in a vehicle;
and one or more of the following components:
c) a traffic control unit (TCU) and traffic control center (TCC) network;
d) traffic operations centers; and
e) a cloud-based platform configured to provide information and computing services,
wherein said system is configured to provide customized vehicle operations and control on specific routes customized for individual vehicles,
wherein vehicle control uses vehicle-specific control instructions comprising longitudinal and lateral position; speed; and steering and control for an individual connected and automated vehicle,
wherein said RSUs are configured to conduct transportation behavior prediction and management, provide planning and decision making, and generate and provide vehicle-specific control instruction including longitudinal and lateral position; speed; and steering and control; and
wherein said system is configured to perform first-mile and last-mile methods comprising:
obtaining user input for trip destination and/or stops;
producing a trip plan using said user input;
obtaining user adjustment or confirmation of said trip plan;
gradually transferring vehicle control from the user to the system during the first mile of the trip; and
gradually transferring vehicle control from the system to the user during the last mile of the trip and/or parking the vehicle.

2. The system of claim 1 configured to provide individual vehicles with detailed customized information and time-sensitive control instructions, including longitudinal and lateral position; speed; and steering and control, for vehicles to fulfill driving tasks and to provide operations and maintenance services for vehicles on both freeways and urban arterials.

3. The system of claim 1 , wherein the system is managed as an open platform for a CAVH system configured to support third party applications and services and to provide interfaces for external agency requests and services.

4. The system of claim 1 , wherein the system is configured to provide:
a) sensing from the RSUs;
b) transportation behavior prediction and management from the RSUs;
c) planning and decision making from the RSUs; and
d) vehicle control with vehicle-specific control instructions from the RSUs.

5. The system of claim 1 , further comprising:
a) a component configured to provide real-time communication via wired and wireless media;
b) a power supply network; and
c) a cyber-safety, security, and privacy protection system for automated driving.

6. The system of claim 5 , wherein said cyber-safety and security system for CAVH system security and protection is configured to provide:
a) network-level protection to minimize and/or prevent unauthorized network access;
b) cloud-level protection to secure vehicle surrounding data, vehicle status data, and traffic state data stored in the cloud; and
c) application-level protection to prevent various cyber threats using fuzzing and penetration testing.

7. The system of claim 6 , wherein said cyber threats for CAVH system comprise one or more of:
a) obtaining confidential personal information;
b) corrupting, damaging, or destroying information; and
c) preventing access to information;
wherein the information refers to vehicle surrounding data, vehicle status data, or traffic state data.

8. The system of claim 1 , wherein said cloud-based platform is configured to provide information services, external services, and compute resources to said system, and provides the networks of RSUs and TCC/TCUs with information and computing services, including Control as a service (CCaaS), providing additional control capability, including generating and providing vehicle-specific control instruction comprising longitudinal and lateral position; speed; and steering and control, as a service for the system.

9. The system of claim 1 configured to perform a route selection method comprising:
a) obtaining user inputs for OD information, vehicle information, and/or user preference,
b) selecting a route based on user inputs; and
c) calibrating a route using collected historical routing data regarding safety, mobility, users' opinions, and traffic conditions;
wherein the route selection method is implemented by the CAVH system.

10. The system of claim 1 configured to pull data from the cloud platform and/or third party sources for road segments on the selected route that are not covered by the system or not covered completely by the system.

11. The system of claim 1 configured to perform:
a) an automatic trip generation method for automated driving, comprising generating an optimized stop sequence and corresponding routes based on user requests, sensing information, and the operational status of said system;
b) a manual trip generation method comprising obtaining a stop sequence from a user and calculating suggested routes for selection by a user.

12. The system of claim 1 configured to assign priority to users to achieve automated driving based on:
location of emergency vehicles,
fee payment options of users,
vehicle occupancy,
arrival time requests,
automation levels of vehicles, and
road coverage of the CAVH system.

13. The system of claim 1 configured to provide en route services to vehicles, wherein said en route services perform driving tasks for vehicles at a microscopic level, mesoscopic level, and macroscopic level.

14. The system of claim 1 configured to perform a method for conflict point control comprising:
a) detecting the movement of vehicles, objects, and/or pedestrians at a conflict point;
b) predicting the movement of said vehicles, objects, and/or pedestrians at said conflict point;
c) identifying potential conflicts of said vehicles, objects, and/or pedestrians; and
d) providing control instructions, including longitudinal and lateral position; speed; and steering and control, to vehicles to prevent conflicts and to maximize efficiency and safety.

15. The system of claim 1 configured to provide warning messages to vehicles and/or to pedestrians and non-motor vehicles, wherein said warning messages provided to vehicles comprise information describing location, type, and movement of vulnerable objects that cause potential risks for said vehicles and said warning messages provided to pedestrians and non-motor vehicles comprise information describing location, type, and movement of vehicles that cause potential risks to said pedestrians and non-motor vehicles.

16. The system of claim 1 configured to perform prediction and management methods for walking, cycling, public transit, and private vehicle travel modes, wherein said prediction and management methods comprise:
a) modeling a road network; and
b) relating traffic conditions to external information sources.
