What is the recommended length for a one-lane, two-way taper regardless of speed?

The recommended length for a one-lane, two-way taper is based on creating a safe transition for vehicles entering the taper zone, and the range of 50 to 100 feet is optimal for achieving this goal regardless of speed. This range is established to ensure that drivers have adequate space to adjust their speed and maneuver safely.

In a one-lane, two-way taper scenario, the taper allows vehicles to merge into or diverge from traffic while minimizing confusion and reducing the risk of collisions. A taper that is too short may not provide sufficient distance for drivers to react, especially in scenarios where traffic conditions are unpredictable or when vehicles are traveling at higher speeds.

Choosing a length in the range of 50 to 100 feet ensures that the taper is long enough to facilitate a smooth transition without causing undue delays for drivers. This length is supported by traffic control guidelines and practices aimed at maximizing safety in work zones and temporary traffic management situations.
