Abstract
This application relates to a method and a system for automatically detecting jaywalking of vulnerable road users (VRUs). In one aspect, the method includes first determining whether a detected current trajectory of the first VRU substantially matches a first path infrequently taken by the plurality of VRUs. The method also includes second determining whether a predicted trajectory of a selected VRU crosses a second path frequently taken by a plurality of vehicles based on the past trajectory data of the plurality of vehicles. The method further includes third determining whether the predicted trajectory of the selected VRU is substantially distal to a third path marked for VRU use. The method further includes determining whether the selected VRU is jaywalking based on the first determining, the second determining, and the third determining.
