Banquet (street)
In the street cross-section, the shoulder of a street is the part of the street crown that is located next to the carriageway , often laterally bounded by an embankment . It is not used for vehicle traffic, but can often be used by pedestrians . Banquets divert the surface water to the troughs on the side . They usually have slopes of 6 to 12%. Regular maintenance, usually mowing the grass, is important to ensure road safety and to maintain the state of construction. Unkempt shoulders lead to backwater formation. Banquets increase automatically due to road dirt and vegetation residues and must therefore be milled over a width of approx. 0.6 meters every 3 to 6 years. 3 to 5 cm of soil and vegetation are removed.
function
Banquets have a structural function. In addition, they should serve as a space for pedestrians and as a work space for road maintenance in order to set up passive protective devices, guidance systems and traffic signs, and especially if there are no sidewalks .
Sturdy banquets (for example with gravel lawns) with a width of up to 2 m enable a car to be parked in an emergency without any major disruption to the flow of traffic and facilitate operations. Banquets with such a larger width should therefore be considered in heavy traffic or heavy traffic, especially for sections of the route in which overtaking is prohibited or where passive safety devices are arranged next to the road.
