Abstract
A system for determining a type of a road upon which a vehicle is traveling includes a processor and a memory in communication with the processor. The memory has a road type determination module having has instructions that cause the processor to determine, using sensor data having information about at least one of a vehicle and a road upon which the vehicle is traveling, that the vehicle previously traveled on a ramp leading to a limited access highway. The road type determination module also has instructions that cause the processor to determine, using the sensor data, that the road is a limited access highway when the vehicle is traveling at or below a first predetermined speed for a first predetermined amount of time sufficiently immediately after determining that the vehicle was traveling on a ramp, and the vehicle is behind one or more preceding slow-moving vehicles.
