Question

When the v/c ratio for a given lane group of an intersection is greater than one, there is not sufficient capacity for the intersection. What actions may be taken to provide sufficient capacity for the intersection when v/c ratio is greater than one?

Answer 1

There are following ways by which we can improve the capacity of any intersection:

1. By allowing less headway
2. Restricting car width so that we can fit more lanes into the same space.
3. Providing separate lanes and parking zones for cars having more width.
4. By using batter traffic management aids like GPS, ETags etc.
5. By designing the most efficient signal
6. Providing dedicated lanes for high-speed vehicles so that clearance is quicker and more vehicles can be accommodated in less time.
