Two-way trip
A person trip is a one-way journey by one person by any mode of transport, including walking, cycling, privately-operated motor vehicles, or any public transport modes.
A vehicle trip is a one-way journey by a single privately-operated motor vehicle regardless of the number of persons in the vehicle.
A vehicle movement is a journey made by a vehicle that can either be a one-way or two-way trip.
Two-way trips are the total number of vehicle movements in both directions. For example, if there are 200 westbound vehicles and 100 eastbound vehicles, there would be 300 two-way trips.
