Controlling host vehicle based on detection of a one-way road
First Claim
1. A system for detecting whether a road on which a host vehicle travels is a one-way road, the system comprising:
- at least one processing device programmed to;
receive, from an image capture device, at least one image associated with an environment of the host vehicle;
identify, based on analysis of the at least one image, a first plurality of vehicles on a first side of the road on which the host vehicle travels;
identify, based on analysis of the at least one image, a second plurality of vehicles on a second side of the road on which the host vehicle travels, the second side being opposite to the first side;
determine a first facing direction associated with the first plurality of vehicles;
determine a second facing direction associated with the second plurality of vehicles; and
use the first facing direction and the second facing direction to determine that the host vehicle is on a one-way road and, in response to the determination, cause at least one navigational change of the host vehicle when the first facing direction and the second facing direction are both opposite to a heading direction of the host vehicle.

Abstract
Systems and methods are provided for navigating an autonomous vehicle. In one implementation, a system for detecting whether a road on which a host vehicle travels is a one-way road may include at least one processing device. The processing device may be programmed to receive at least one image associated with an environment of the host vehicle, identify a first plurality of vehicles on a first side of the road, identify a second plurality of vehicles on a second side of the road, determine a first facing direction associated with the first plurality of vehicles, determine a second facing direction associated with the second plurality of vehicles, and cause at least one navigational change of the host vehicle when the first facing direction and the second facing direction are both opposite to a heading direction of the host vehicle.

8. A method for detecting whether a road on which a host vehicle travels is a one-way road, the method comprising:
-
receiving, from an image capture device, at least one image associated with an environment of the host vehicle; identifying, based on analysis of the at least one image, a first plurality of vehicles on a first side of the road on which the host vehicle travels; identifying, based on analysis of the at least one image, a second plurality of vehicles on a second side of the road on which the host vehicle travels, the second side being opposite to the first side; determining a first facing direction associated with the first plurality of vehicles; determining a second facing direction associated with the second plurality of vehicles; and using the first facing direction and the second facing direction to determine that the host vehicle is on a one-way road and, in response to the determination, causing at least one navigational change of the host vehicle when the first facing direction and the second facing direction are both opposite to a heading direction of the host vehicle. - View Dependent Claims (9, 10, 11, 12, 13)

14. A non-transitory computer-readable medium storing instructions, which, when executed by at least one processing device, perform a method comprising:
-
receiving, from an image capture device, at least one image associated with an environment of a host vehicle; identifying, based on analysis of the at least one image, a first plurality of vehicles on a first side of a road on which the host vehicle travels; identifying, based on analysis of the at least one image, a second plurality of vehicles on a second side of the road on which the host vehicle travels, the second side being opposite to the first side; determining a first facing direction associated with the first plurality of vehicles; determining a second facing direction associated with the second plurality of vehicles; and using the first facing direction and the second facing direction to determine that the host vehicle is on a one-way road and, in response to the determination, causing at least one navigational change of the host vehicle when the first facing direction and the second facing direction are both opposite to a heading direction of the host vehicle. - View Dependent Claims (15)

16. A system for navigating a host vehicle, the system comprising:
at least one processing device programmed to; receive a navigation instruction to navigate the host vehicle from a first road on which the host vehicle is traveling to a second road; receive, from an image capture device, at least one image associated with an environment of the second road; identify, based on analysis of the at least one image, a first plurality of vehicles on a first side of the second road; identify, based on analysis of the at least one image, a second plurality of vehicles on a second side of the second road, the second side being opposite to the first side; determine a first facing direction associated with the first plurality of vehicles; determine a second facing direction associated with the second plurality of vehicles; use the first facing direction and the second facing direction to determine that the second road is a one-way road and, in response to the determination, determine that the first facing direction and the second facing direction are both opposite to a heading direction the host vehicle would travel if the host vehicle were to navigate onto the second road; and suspend the navigation instruction in response to the determination that the first facing direction and the second facing direction are both opposite to the heading direction the host vehicle would travel if the host vehicle were to navigate onto the second road. - View Dependent Claims (17, 18, 19, 20)
