Traffic in the street is organized and regulated by signing.

Above all, streets provide the main transport network in urban areas. Pedestrians and personal transport modes (in-line skates, bicycles, motorcycles and cars) and public transport modes (buses and trams) share the street with vehicles that transport goods and waste.

The space is frequently organized to separate these different modes, for example by the use of footpaths, exclusive lanes or grade-separated crossings. Traffic lights are used to co-ordinate the different traffic flows.

Travel in streets is regulated and organized. Signing, both vertical (traffic lights and signs) and horizontal (white or coloured lines, rumble strips) inform those on the road about the rules that apply, for example the speed limit.

Large cities have centrally controlled co-ordinated systems of traffic lights known as urban traffic control systems.
