Abstract: The disclosure includes implementations for estimating a presence of an obstruction in a roadway using wireless vehicle data. A method may include receiving a Dedicated Short Range Communication (“DSRC”) message that includes path history data describing a path of a first DSRC-equipped vehicle with lane-level accuracy over a plurality of different times while the first DSRC-equipped vehicle is traveling on a roadway. The method may include determining a presence of an obstruction in a specific lane of the roadway based on the path history data. The obstruction may be indicated by the path history data because the path history data indicates that the obstruction affected the path of the first DSRC-equipped vehicle while traveling in the specific lane of the roadway. The method may include providing a recommendation to a driver of a second DSRC-equipped vehicle. The recommendation may describe the presence of the obstruction in the specific lane.

Abstract: The disclosure includes a system and method for managing traffic in a roadway system based on Basic Safety Message data (“BSM data”) included in a set of Basic Safety Messages (“BSMs”). The method may include wirelessly receiving a set of BSMs describing a set of vehicles traveling along the roadway system. Each BSM included in the set of BSMs may describe a specific vehicle included in the set of vehicles, including that vehicle's lane, speed and heading of travel. The method may include analyzing the BSM data to determine whether there is an imbalance of traffic flow among a first set of vehicles traveling towards a first heading and a second set of vehicles traveling towards a second heading. The method may include determining that the bidirectional lane will be reconfigured so that traffic in the bidirectional lane flows towards the second heading based on the imbalance of traffic flow.

Abstract: The disclosure includes implementations for determining a position of a vehicle using millimeter wave narrow beamforming. A method may include receiving a set of training packets that each uniquely identify a position on a portion of a roadway where the vehicle is located. Each of the training packets included in the set may be associated with only one of the millimeter wave narrow beams. The method may include identifying a training packet included in the set of training packets that has a highest receive power level among the set of training packets. The method may include determining the position uniquely identified by the training packet having the highest receive power level. The method may include determining positional information for the vehicle based on the position uniquely identified by the training packet having the highest receive power level. The positional information may describe a location of the vehicle on the roadway.

Abstract: The disclosure includes a system and method for providing vehicular traffic assistance. The method may include wirelessly providing a first navigation route to a navigation system of the vehicle to assist the vehicle to arrive at a destination, where the first navigation route includes one or more roadways for the vehicle to travel to arrive at the destination. The method may include receiving decision data from a roadway authority. The decision data may describe a set of traffic management decisions made by the roadway authority that affect travel along at least one of the roadways included in the first navigation route. The method may include proactively determining a second navigation route to assist the vehicle to arrive at the destination, where the second navigation route is configured so that it does not include any roadway that is affected by the set of traffic management decisions made by the roadway authority.

Abstract: The disclosure includes implementations for providing a recommendation to a driver of a second DSRC-equipped vehicle. The recommendation may describe an estimate of how long it would take the second DSRC-equipped vehicle to receive a roadside service from a drive-through business. A method according to some implementations may include receiving, by the second DSRC-equipped vehicle, a Dedicated Short Range Communication message (“DSRC message”) that includes path history data. The path history data may describe a path of a first DSRC-equipped vehicle over a plurality of different times while the first DSRC-equipped vehicle is located in a queue of the drive-through business. The method may include determining delay time data for the second DSRC-equipped vehicle based on the path history data for the first DSRC-equipped vehicle. The delay time data may describe the estimate. The method may include providing the recommendation to the driver. The recommendation may include the estimate.
