## Abstract

A method for a driver assistance system of a driver's vehicle is provided. The method comprises detecting a location of the driver's vehicle and a lane that the driver's vehicle is traveling along; identifying a nearby vehicle in a vicinity of the driver's vehicle based on sensor data; identifying a lane that the nearby vehicle is traveling along based on the location of the driver's vehicle, map data comprising traffic lane information, and the sensor data; determining, based on the driver's vehicle lane and the nearby vehicle lane, that the driver's vehicle lane and the nearby vehicle lane will merge; and outputting a driver alert based on the determination.

### Claim 5 (depends on 1)

The method of claim 1, wherein identifying the nearby vehicle lane comprises adding the map data comprising traffic lane information to the sensor data and determining that a nearby vehicle lane confidence metric meets a nearby vehicle lane threshold.

### Claim 6 (depends on 1)

The method of claim 1, wherein determining that the driver's vehicle lane and the nearby vehicle lane will merge is further based on the map data comprising traffic lane information.

### Claim 7 (depends on 1)

The method of claim 1, wherein outputting the driver alert comprises computing a nearby vehicle location and a nearby vehicle velocity based on the driver's vehicle location, the map data, and the sensor data.

### Claim 8 (depends on 7)

The method of claim 7, wherein outputting the driver alert comprises computing an estimated distance between the driver's vehicle and the nearby vehicle at a location of the merge based on the driver's vehicle location, a driver's vehicle velocity, the nearby vehicle location, and the nearby vehicle velocity.

### Claim 9 (depends on 8)

The method of claim 8, wherein outputting the driver alert is further based on a determination that the estimated distance between the driver's vehicle and the nearby vehicle at the location of the merge meets a proximity threshold.

### Claim 10 (depends on 1)

The method of claim 1, wherein outputting the driver alert comprises at least one of illuminating an indication light or generating an audible tone.

### Claim 11 (depends on 1)

The method of claim 1, wherein outputting the driver alert comprises displaying, on a user interface, at least one of an indication of the nearby vehicle, a recommended merge location, or a recommendation to modify or maintain a velocity of the driver's vehicle.

### Claim 12

A method for a driver assistance system of a driver's vehicle, the method comprising:
detecting a location of the driver's vehicle and a lane that the driver's vehicle is traveling along;
identifying a nearby vehicle in a vicinity of the driver's vehicle based on sensor data;
identifying a lane that the nearby vehicle is traveling along based on the location of the driver's vehicle, map data comprising traffic lane information, and the sensor data;
computing a probability, based on the driver's vehicle lane and the nearby vehicle lane, that at least one of the following will occur: the driver's vehicle will enter the nearby vehicle lane or the nearby vehicle will enter the driver's vehicle lane; and
outputting a driver alert based on the probability.

### Claim 13 (depends on 12)

The method of claim 12, wherein detecting the location of the driver's vehicle is based on global positioning system satellite data.

### Claim 14 (depends on 12)
