What is class separation?

Grade separation is a process used to improve traffic flow at intersections and intersections. When designing class separation, each surface of the road or rail is located in a different stage or height. This difference in height is made using tunnels, ramps, bridges and exchanges at any point where both roads or rails walk each other. For example, an elevated train running over the road is considered an example of a railway class department. Urban Light Rail System, where train cars move with street level operation, is not separated. These projects can include railways, freight trains, metro or metro, monorail or even pedestrian sidewalks. Even the process of separating two separate car roads is considered to be the type of class separation.

in a fully separated or free -flowing design design design, operation in all directions can continue to flow without stopping or slowing, where the road, rail or paths cross. An example would be a pedestrian or junction bridgeAnd the "needle" where elevated ramps allow vehicles to travel from one highway to another without stopping. Partially separate stages include intersections where motorists or pedestrians could slow down or give up, such as a roundabout. The traditional intersection that uses traffic signals does not include any class separation.

This type of project design offers a number of advantages over roads and rails that are all built at the same height. All types of operations are able to flow freely freely, with small to any interruptions and speed limits are usually higher. The biggest advantage is the separation of different types of traffic, including cars, trains and pedestrians, which reduces the risk of accidents for all parties.

At the same time, many people who live near the intersection of separate classes are often built. In general, they are built relatively high, which can prevent opinions. Especially the appearance of roads and bridges separatedIt is generally unpleasant and consists of solid concrete or steel structures that reach high into the air. Building tunnels or bridges is much more expensive than building on the ground level and these projects take up a lot of space, both during and after construction. Finally, the complexity of these projects often means that completion takes a long time, which can disrupt the flow of operation for years.
