I am aware of two studies that investigated barrier-mounted signs. CALTRANS performed a study that crash tested a sign with unacceptable safety performance. TTI also conducted a multi-phase study that simulated several systems and then evaluated those systems with crash testing. I believe that a few configurations provided acceptable performance.
In terms of delineators, I would believe that reflectors or sheeting could be safety applied to the posts and the depressions in the upper rail. I do not have any specifics for types of reflectors or sheeting. However, I do not think that they would pose a risk to passenger vehicles or the tank.
One thought may be to contact 3M or other manufacturers to inquire about products for this special application. Would you like for us to have a student investigate further options?
