Draining streets
Introduction
The roadway is the part of the road or street intended for the circulation of vehicles. It is made up of one or more lanes and is usually delimited by elements such as sidewalks, shoulders, medians or other spaces designed for specific uses. Its main function is to facilitate the transit of vehicles efficiently and safely.
Definition and characteristics
The road is a road infrastructure intended for the movement of vehicles, composed of the following main elements:.
• - Lane: longitudinal area that orders the traffic of vehicles.
• - Shoulder: lateral area used in emergencies or to stop.
• - Median "Median (traffic)"): space that separates the roads on two-way roads.
• - Island and shelter&action=edit&redlink=1 "Shelter (traffic) (not yet written)"): elements that organize traffic and provide safety for pedestrians.
In urban areas, the road is distinguished from the sidewalk, reserved for pedestrian traffic.
Contexts of use
Roads and highways
On roads, highways and motorways, there may be several carriageways separated by medians "Median (traffic)"). These separations guarantee safety and reduce interactions between vehicles traveling in opposite directions. They may also include emergency or exclusive lanes for certain types of vehicles.
Urban areas
In urban areas, roadways include lanes for buses, bicycles or private vehicles. Urban design seeks to integrate elements such as pedestrian crossings, traffic lights, road markings and traffic signals.
History
The term "road" comes from the Vulgar Latin calciāta, which means "road paved with lime".[1] In ancient times, civilizations such as the Romans and the Aztecs used roads as main routes for commerce and communication.
