Turn assist system and method using dedicated short-range communications

A turn assist system comprising:

• a receiver of a primary vehicle configured to receive travel path data of a remote vehicle transmitted by the remote vehicle and map coordinates for a plurality of lanes of a multilane road transmitted by roadside equipment located at an intersection;
• a lane tracking module of the primary vehicle configured to, based on the travel path data of the remote vehicle and based on the map coordinates of the plurality of lanes, determine which lane of the multilane road the remote vehicle will be in when the primary vehicle will enter the intersection and determine whether the remote vehicle will be in the intersection in a nearest lane, of the plurality of lanes, to the primary vehicle when the primary vehicle will enter the intersection, while the primary vehicle is at the intersection in a crossing lane and waiting to enter the intersection into the nearest lane, the nearest lane being a lane of the plurality of lanes of the multilane road that is closest to the primary vehicle while located in the crossing lane;
• and
• an alert module of the primary vehicle configured to, based on a result of the determination performed by the lane tracking module, notify a driver of the primary vehicle that it is unsafe to make a turn at the intersection, in response to determining that the remote vehicle will enter the intersection in the nearest lane,
• wherein:
• determining whether the remote vehicle will enter the intersection in the nearest lane includes determining whether the remote vehicle will change lanes prior to entering the intersection,
• the primary vehicle is traveling in a first direction,
• the remote vehicle is traveling in a second direction, and
• the first direction is not parallel to the second direction.
