Embodiments described herein may provide a method for using vehicle probe data to identify speed funnels that are related to road construction. Methods may include: receiving probe data including sensor data from a probe apparatus collected along a sequence of road segments; determining, from the sensor data, if an indication of a start of road work has been detected; constructing a Finite State Automata (FSA) for the probe data collected along the sequence of road segments; determining, in the probe data, sensor data indicative of a sequence of speed limit value observations; identifying, using the FSA, a speed funnel based on a pattern of speed limit values within the sequence of speed limit value observations; and providing an indication of the speed funnel occurring within the sequence of road segments for at least one of navigational assistance or at least semi-autonomous vehicle control.
