Traffic Obstruction Notification System Based on Wireless Vehicle Data
First Claim
1. A method for a Dedicated Short Range Communication-equipped (“
- DSRC-equipped”
) vehicle, the method comprising;
collecting, by a sensor set included in a first DSRC-equipped vehicle, sensor data that describes a plurality of locations of the first DSRC-equipped vehicle with lane-level accuracy at a plurality of different times while the first DSRC-equipped vehicle is traveling on a roadway, wherein the sensor set includes a DSRC-compliant GPS unit that generates the sensor data describing the plurality of locations with lane-level accuracy;
building, by the first DSRC-equipped vehicle, first path history data based on the sensor data, wherein the first path history data describes a path of the first DSRC-equipped vehicle with lane-level accuracy over the plurality of different times while the first DSRC-equipped vehicle is traveling the roadway;
wirelessly transmitting, by the first DSRC-equipped vehicle, a DSRC message that includes the first path history data to a second DSRC-equipped vehicle;
receiving the DSRC message by the second DSRC-equipped vehicle;
receiving a wireless message by the second DSRC-equipped vehicle, wherein the wireless message is transmitted by a computing device and includes second path history data for one or more other vehicles that describes one or more paths of the one or more other vehicles while traveling on the roadway;
determining, by the second DSRC-equipped vehicle, a presence of an obstruction in a specific lane of a roadway based on the first path history data and the second path history, wherein the obstruction is indicated by the first path history data and the second path history data because the first path history data and at least a portion of the second path history data indicates that the obstruction modified the path of the first DSRC-equipped vehicle and at least one of the one or more other vehicles while traveling in the specific lane of the roadway; and
providing, by the second DSRC-equipped vehicle, a recommendation to a driver of the second DSRC-equipped vehicle, wherein the recommendation describes the presence of the obstruction in the specific lane of the roadway.

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.

10. A system comprising:
-
a DSRC receiver of a second DSRC-equipped vehicle that is operable to receive a 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; an onboard vehicle computer system of the second DSRC-equipped vehicle that is communicatively coupled to the DSRC receiver to receive the path history data from the DSRC receiver, the onboard vehicle computer system including a non-transitory memory storing computer code which, when executed by the onboard vehicle computer system causes the onboard vehicle computer system to; determine a presence of an obstruction in a specific lane of the roadway based on the path history data, wherein the obstruction is 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; and provide a recommendation to a driver of the second DSRC-equipped vehicle, wherein the recommendation describes the presence of the obstruction in the specific lane of the roadway. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A computer program product comprising a non-transitory memory of an onboard vehicle computer system of a second DSRC-equipped vehicle storing computer-executable code that, when executed by a processor, causes the processor to:
-
receive a 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; determine a presence of an obstruction in a specific lane of the roadway based on the path history data, wherein the obstruction is 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; and provide a recommendation to a driver of the second DSRC-equipped vehicle, wherein the recommendation describes the presence of the obstruction in the specific lane of the roadway. - View Dependent Claims (19, 20)
