The article describes how portable message signs equipped with cellular phones were of great value in diverting traffic, reducing speed, and other advisory functions related to traffic congestion and accidents, when Baltimore's Jones Falls Expressway was upgraded. This was the first system of its type to use cellular telephones, and the critical lessons learned are noted. The generic specification that was developed for the acquisition of variable message signs are listed. Alternative travel routes were implemented for each sector of the city and a public information campaign was mounted. Hot lines provided up-to-the-minute information on areas of construction. Local street signal system timings were adjusted to meet traffic loads as necessary. The newspapers and radio stations kept abreast of the construction activity.
