Patent attributes
A method and system may provide speed limit data to users driving in vehicles. A user's client device such as a smart-phone, smart watch, or tablet computer, may provide visual, audible, and/or haptic alerts to the user when the user exceeds a posted speed limit by more than a threshold amount. For example, when the user exceeds the posted speed limit by more than the threshold amount, the user's smart-phone may play a beeping sound and may announce the posted speed limit to the user. A map of a geographic area including the user's travelled route may also be displayed, with annotated areas along the route where the user exceeded the posted speed limit. The map may also include an indication of a proportion of a duration or distance of the route in which the user travelled above the posted speed limit.
