197. Mediana
Una mediana, también llamada separador central, es una zona longitudinal entre calzadas separadas, normalmente destinada a dividir el tráfico que circula en sentidos opuestos. Puede estar formada por césped, pavimento, barreras, vegetación u otro tipo de separación física.
La mediana ayuda a separar los flujos de tráfico opuestos y puede reducir el riesgo de que los vehículos invadan directamente la circulación contraria. Puede disponer de aperturas en lugares seleccionados para giros, intersecciones, acceso de emergencia u otros movimientos autorizados.
What is a median strip?
A median strip is a longitudinal area that separates two roadways, usually carrying traffic in opposite directions.
Is a median strip the same as a road marking?
Not necessarily. A median is normally a physically distinguishable area or structure, while painted centre lines simply separate traffic using road markings.
What can a median strip be made of?
A median may consist of grass, paving, kerbs, safety barriers, vegetation or another physical separation between roadways.
Why are median strips used?
They help separate opposing traffic flows, reduce conflicts between vehicles travelling in opposite directions and provide space for barriers, signs, lighting or other road infrastructure.
Can you drive across a median strip?
Only where a legal crossing or opening is provided and the applicable traffic rules permit the movement. Drivers should never cross a physical median simply to change direction or take a shortcut.
Can a median strip have openings?
Yes. Openings may be provided for intersections, turning movements, emergency services, maintenance or other authorised traffic.
Can you park on a median strip?
This depends on local law, but parking on a median is commonly prohibited or restricted because it may create danger or obstruct visibility and traffic.
Can pedestrians stand on a median strip?
Some medians contain a pedestrian refuge specifically designed to allow people to cross a road in stages. Other medians may not be intended for pedestrian use.
Is a central safety barrier part of the median?
It can be. A median may contain a safety barrier designed to reduce the risk of vehicles crossing into opposing traffic.
Can a divided road have more than one roadway?
Yes. A road with a median commonly has two separate roadways, one for each direction of traffic.
Does a median strip determine the direction of traffic?
The road layout normally separates the traffic directions, but drivers must still follow the traffic signs, lane markings and directional rules applying to each roadway.
Is a median strip the same as an emergency lane?
No. An emergency lane or shoulder runs alongside a roadway, while a median strip separates roadways from each other.
