Vehicle operation on an on-ramp

A method, comprising:

• determining (a) a first vehicle is driving on a curve on a first road or, (b) by detecting a second road, a road boundary of the first road;
• determining (c) parallel traffic by determining that a second vehicle is moving in a lane of the second road adjacent to the first road, or (d) tangential traffic by detecting a third vehicle is moving tangentially to the curve;
• and
• upon determining that there is simultaneously at least one of (a) the first vehicle driving on the curve on the first road or (b) the road boundary of the first road, and at least one of (c) parallel traffic or (d) tangential traffic, then determining that the first vehicle is driving on an on-ramp.

An apparatus, comprising a device configured to:

• determine (a) a first vehicle is driving on a curve on a first road or, (b) by detecting a second road, a road boundary of the first road;
• determine (c) parallel traffic by determining that a second vehicle is moving in a lane of the second road adjacent to the first road, or (d) tangential traffic by detecting a third vehicle is moving tangentially to the curve;
• and
• upon determining that there is simultaneously at least one of (a) the first vehicle driving on the curve on the first road or (b) the road boundary of the first road, and at least one of (c) parallel traffic or (d) tangential traffic, then determine that the first vehicle is driving on an on-ramp.
