Traffic

In many parts of the world traffic is generally organized, flowing in lanes of travel for a particular direction, with interchanges, traffic signals, or signage at intersections to facilitate the orderly and timely flow of traffic. Traffic can be separated into vehicular, non-vehicular (bicycling), and pedestrian classes of traffic. Vehicles of the same class share their speed limits and share easement with one another. Cooperative signaling arrangements can also be made with representatives of other classes of traffic.
