In what scenario should a turnout be placed at least 50 meters after a road intersection?

A turnout should be placed at least 50 meters after a road intersection primarily to improve safety for turnouts. This distance allows for adequate separation between the traffic flow at the intersection and the vehicles using the turnout. Vehicles turning off the main road can disrupt traffic and create hazardous situations if the turnout is too close to the intersection. By positioning the turnout further down the road, drivers have more time to react and adjust to changing traffic conditions, reducing the likelihood of accidents.

Factors like traffic volumes and pedestrian presence also matter, but the core reason for the 50-meter distance is the enhancement of safety. The ideal scenario aims to allow drivers sufficient space to maneuver without interfering with vehicles exiting or entering the intersection, thereby promoting smoother traffic flow and reducing the risk of collisions.
