1. A system for determining road conditions, comprising:
- an input interface configured to;
receive sensor data from one or more sensors; and
a processor configured to;
determine vehicle maneuver data associated with a current vehicle stopping maneuver based at least in part on the sensor data;
retrieve historical vehicle maneuver data associated with one or more historical vehicle stopping maneuver data instances;
determine a road slipperiness value for the current vehicle stopping maneuver based at least in part on the vehicle maneuver data and the historical vehicle maneuver data, wherein the historical vehicle maneuver data comprises a road slipperiness value for each historical vehicle stopping maneuver data instance of the one or more historical vehicle stopping maneuver data instances; and
update an event detection threshold based at least in part on the road slipperiness value for the current vehicle stopping maneuver.

18. A method for determining road conditions, comprising:
-
receiving sensor data from one or more sensors; determining, using a processor, vehicle maneuver data associated with a current vehicle stopping maneuver based at least in part on the sensor data; retrieving historical vehicle maneuver data associated with one or more historical vehicle stopping maneuver data instances; determining a road slipperiness value for the current vehicle stopping maneuver based at least in part on the vehicle maneuver data and the historical vehicle maneuver data, wherein the historical vehicle maneuver data comprises a road slipperiness value for each historical vehicle stopping maneuver data instance of the one or more historical vehicle stopping maneuver data instances; and updating an event detection threshold based at least in part on the road slipperiness value for the current stopping maneuver.
