197. Terre-plein central
Un terre-plein central, également appelé séparateur central, est une zone longitudinale située entre des chaussées séparées, généralement pour diviser les flux circulant en sens opposés. Il peut être constitué d’herbe, d’un revêtement, de barrières, de végétation ou d’une autre séparation physique.
Un terre-plein central aide à séparer les flux opposés et peut réduire le risque qu’un véhicule passe directement dans la circulation venant en sens inverse. Des ouvertures peuvent être prévues à certains endroits pour les véhicules tournant, intersections, accès d’urgence ou autres mouvements autorisés.
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.
