Project Description:
The main goal of this study is to assess the effectiveness and essential role of flaggers and spotters in directing work zone traffic for expressways
and freeways in Illinois with a posted speed limit greater than 40 mph and consider alternative means of providing this function. The study's
findings on the roles and effectiveness of flaggers versus spotters for directing work zone traffic control should guide decision-makers on changing
policy to allow an expanded use of work zone spotters to improve work zone safety and mobility performance in future road and bridge
construction projects.
