1. A vehicle comprising:
- a vehicle computer programmed to;
store vehicle speed data in a memory; and
output a smoothness rating of the vehicle at a display, the smoothness rating generated based on integrating a difference between speed of the vehicle associated with a road segment and a nominal velocity profile of a plurality of vehicles that have driven on the road segment, divided by a distance of the road segment.

Abstract
A method of rating driver effectiveness based on vehicle data compared to other vehicles that have driven over the same road segment includes storing driving speed data over a road segment for a plurality of vehicles. The method further includes calculating a nominal speed profile for the road segment based on the driving speed data. The method further includes comparing a speed profile of a subject vehicle to the nominal speed profile for the road segment and displaying a smoothness rating of the subject vehicle based on deviation of the speed profile from the nominal speed profile.

9. A method comprising:
-
storing, in a database, driving speed data over a road segment for a plurality of vehicles; calculating a nominal speed profile for the road segment using the driving speed data; and displaying a driver smoothness rating based on integrating a difference between speed of the vehicle and nominal speed profile associated with the road segment, divided by a distance of the road segment. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A driver performance server comprising:
a processor configured to communicate with a vehicle computing system (VCS), the processor programmed to; in response to vehicle data including a location and vehicle speed received from the VCS; retrieve a road segment; calculate a nominal velocity for the road segment based on a plurality of vehicles that have driven on the road segment; calculate a smoothness rating based on integrating a difference between the nominal velocity and the vehicle speed for the road segment; and transmit the smoothness rating to the VCS. - View Dependent Claims (18, 19, 20)
