Methods and systems for monitoring vehicle motion with driver safety alerts

#A driver of a vehicle relies on signage painted on the roadways or signposts on the side of the roadways to adapt the speed of the vehicle and steering to control the direction of travel along one-way roads, two-way roads, bridges, parking lots, and garages, for example. When a driver is driving along a road, the driver's attention may be diverted in the direction of moving or stationary objects, pedestrians and the like. A driver's attention may be diverted when the driver is changing the radio station or adjusting the vehicle's climate control. It is also common for a driver to consume food and beverages, talk on the phone or text while driving. All of these tasks can take the driver's attention off the road even if it is only for a second. As a consequence, certain traffic control measures, such as traffic stop signs and a change in color of a traffic light may go unseen. This can cause the driver to fail to stop at a stop sign or a red light, for example. Failing to stop at a stop sign, a red light or other traffic control measures increases the likelihood of a collision by the vehicle with another vehicle or pedestrian.

#A driver can have their attention focused on the road 100% of the time. However, in some instances, traffic signs can be obscured from the driver's view partially or completely, such as by trees or bushes, which may prevent the driver from stopping at the stop sign. In other instances, once the driver sees the traffic sign, it may be too late for the driver to decelerate the vehicle at a rate sufficient to stop for the traffic sign. A driver may not see a one-way sign blocked by trees or bushes while turning onto a road, which has an opposite heading than the direction of travel of the vehicle. Driving against traffic also increases the likelihood of a collision by the vehicle with another vehicle or pedestrian.

#As used in this document, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art. As used in this document, the term “comprising” means “including, but not limited to.”

#As used in this disclosure, the term “wrong-way direction” is intended to refer to an assigned heading of a lane segment that is opposite the computed heading or direction of travel of the vehicle within a preset tolerance.

#As used in this disclosure, the term traffic control measure (TCM) refers to an object that is installed along, in, or over a lane of a road to control the flow of traffic by slowing and/or stopping the traffic under certain conditions. Examples of TCMs include a stop sign, traffic light signal, a yield sign, a pedestrian crosswalk, and a speed bump.
