  • Highway intersection is the area shared by two or more roads.
  • This area is used by the vehicles to turn to different directions i order to reach their destinations. Its main function is to guide vehicles to different directions.
  • Highway intersections are complex locations on a highway. This is because vehicle moving to different directions want to occupy the same space at the same time. in addition, pedestrians also seek same space for crossing.
  • Drivers have to split second decisions at an intersection by considering his route, intersection geometry, speed and direction of other vehicles.
  • Overall traffic flow depends on the performance of intersection. It also affects the capacity of road.
  • From both accident and capacity perspectives, intersection must be studied and designed properly.

LEVELS OF INTERSECTION CONTROL:

Control of intersection can be exercised at different levels. They can be passive control, semi control and active control.

  1. Passive control doesn't require any explicit control of traffic. traffic sign boards and markings will be enough.
  2. In Semi control, drivers are slowly guided to avoid conflict points. It uses traffic channelization and traffic rotaries.
  3. In active control, the road user will be forced to follow the path suggested by traffic agencies. It uses traffuc signals and grade separated intersections.

GRADE SEPERATED INTERSECTIONS:

These are used to separate the traffic in vertical grades. Different types of grade separations are flyover and Interchanges.

Flyover itself is subdivided into overpass(major traffic elevated) and underpass(major traffic depressed).

Common types of interchange are

  1. Trumpet interchange
  2. Diamond interchange
  3. Clover lead interchange etc.,

Traffic engineers are concerned about the rear end collisions that take place at intersections that have a stoplight. When drivers abruptly stop at a yellow light because they are concerned about making it through the intersection, the driver of the car behind theirs may not have anticipated them stopping and a collision occurs. For a 45 mph speed zone, typically the yellow light duration is set at 4.2 seconds. Traffic engineers wonder if setting that duration for a shorter or...
