H3−3: Dissemination of Work Zone Project Information


The Arizona Department of Transportation (ADOT) has an extensive plan for public outreach during construction projects in the State. ADOT's Communications and Community Partnerships Division is involved throughout the design, construction, and maintenance process. ADOT has a hot−line for drivers to report problems on the road for higher interest projects. Also, ADOT is using Arizona 511 traveler information phone numbers, electronic signage, and websites to get information out to motorists. For their recent large−scale construction project on I−10, ADOT had a fully−staffed call center during the day, seven days a week, to answer motorists' questions about the project. In the evening, an automated message described traffic delays, construction plans, etc.

The public information office in each of the eight district offices within the Florida Department of Transportation (FDOT) provides information on the location and duration of construction work zones to the public and the news media. For larger projects, the civil engineering inspection staff includes a project level public information position. On some major projects a toll−free hotline has been established for project information. FDOT also uses websites and social media to disseminate critical project information.

The Illinois Department of Transportation (IDOT) is proactive in notifying the motoring public of upcoming and ongoing construction projects. This is an effort to increase safety for workers and motorists in work zones and to ensure that motorists, local and state law enforcement and government officials, and the general public are made aware of road projects in a timely manner. IDOT uses a variety of platforms to disseminate this information: news releases, social media (Facebook, Twitter, YouTube) and public meetings to get this information to the public. In recent years, the use of social media has allowed the Department to get information out to a larger number of people. Through public service announcements for Work Zone Awareness Week, videos on current projects, and daily content posted on social media websites, IDOT is keeping motorists informed.


To raise public awareness of work zones and inform the motoring public about the location, duration, and impacts of road projects.


Effective public information and outreach can result in better public relations and fewer traffic impacts due to motorists' ability to better avoid construction delays. The public appreciates being informed and knowing who to contact with concerns. Social media enables faster dissemination of information to a larger audience. These efforts improve image of DOTs.


This practice is applicable to all types of construction projects where the public will be impacted by construction activities.
