How long should each bus turnout be at a minimum?

The minimum length of a bus turnout being 15 meters is based on several key factors related to traffic flow, safety, and operational efficiency. A bus turnout is a designated area where buses can pull off the main roadway to pick up and drop off passengers without obstructing traffic.

The 15-meter minimum ensures that the bus has sufficient space to safely maneuver in and out of the turnout while allowing for a smooth transition back onto the roadway. This length accommodates the dimensions of most transit buses, which are typically around 12 to 14 meters in length. Additionally, the 15-meter length helps reduce potential delays for other vehicles on the road, as it allows the bus to clear the travel lane quickly.

Furthermore, this specification supports safety standards, as it provides enough buffer space for the bus’s extended operations and ensures that there is minimal disruption to the flow of traffic. It also considers factors such as the need for passengers to embark and disembark safely without being in danger of oncoming vehicles.

This minimum guideline is often reinforced by local or national transportation planning standards and best practices in civil engineering that prioritize safe and efficient transit operations.
