To reduce the effects of traffic jams, a traffic reduction system identifies road segments having more a threshold amount of traffic. The traffic reduction system also receives an indication of a current location of a client device operating in a vehicle and compares the current location to the locations of the identified road segments to determine whether the vehicle is on or approaching the road segment. If the vehicle is on or approaching the road segment, the traffic reduction system determines a target speed for the vehicle to maintain an equal distance between the vehicle and the vehicle in front of the vehicle and the vehicle and the vehicle behind the vehicle. The traffic reduction system then provides the target speed to the client device for display on a user interface. By maintaining equal distances between vehicles in front of and behind each other, the amount of traffic dissipates.

A wearable device is provided that includes a receiver, a processor, and a transducer. The receiver is configured to receive speed limit data indicative of a posted speed limit corresponding to a route or road upon which the wearable device is traveling. The processor is configured to compare the speed limit to a current speed of the wearable device and/or a vehicle in which the user wearing the wearable device is driving. The transducer is configured to deliver a haptic or other notification to a user upon which the wearable device is worn when the current speed exceeds the speed limit or exceeds the speed limit by a predetermined amount. As a result, safer driving and vehicle collision avoidance may be facilitated. Safe driving auto insurance discounts may be provided to drivers that use the safe driving or speed limit warning functionality discussed herein.
