3.8.1 State-of-the Practice

Delineators are primarily used at reversible plazas to separate vehicles traveling in opposite directions, to separate higher speed dedicated lanes from the lower speed cash lanes and along the plaza approach and departure zones to assist merging and diverging traffic as it approaches and departs the plaza, respectively. Delineators have also been used within the shoulder at the tolling point of express lanes and ETC dedicated lanes to prevent vehicles from eluding capture by the violation enforcement system cameras.
