Changeable message signs (CMSs) and Highway Advisory Radio (HAR) are playing increasing roles in managing traffic. This report presents the findings of field studies conducted to determine the feasibility of using these traffic management tools during freeway maintenance. The studies revealed that CMSs can be effective traffic management tools at freeway maintenance work zones when they are properly used. At lane closure work zones they may be used to encourage drivers to change lanes earlier. They may be used at other work zones to encourage drivers to divert to alternate freeway routes to avoid work zone congestion. Studies were also conducted at a freeway maintenance work zone to evaluate the use of HAR for work zone traffic management. The studies indicated that it may have good potential for work zone traffic management in other applications (e.g., for displaying long or complicated diversion messages at long-term work zones).
