Changeable Message Sign, I-5, Vancouver Freeway: Final Report, Experimental Feature WA75-02

Description:

A changeable message sign to inform, warn and direct traffic was installed in Vancouver, Washington prior to the initiation of major reconstruction on the Interstate 5 corridor. Despite some operational problems, the sign proved to be of considerable value in informing motorists of the changing roadway configurations necessitated by the construction operations. The use of similar signs in other locations was recommended.
