Calculate direction of a vehicle (Veins/Omnet++/Sumo)

Question

Is it possible to calculate(get) direction of vehicle in Veins(via TraCIMobility)? I want to know if two vehicles are traveling in opposing directions or not. I think I can

Answer 1

You are correct: getAngleRad() returns the vehicle's heading in radians (from -pi up to, but excluding, +pi). A value of 0 means the vehicle is heading east; a value of pi/2 means it is heading north; etc.
