Several conclusions can be drawn from the use of active traffic management in Houston: 1. Advance public information of impending work zone activity can minimize public complaints and erratic behavior by motorists; 2. The active presence of law enforcement officers in urban highway work zones can minimize erratic behavior by motorists; 3. Carefully planned “active traffic management techniques” can allow work zone activity to be done on high-volume urban highways during daylight hours without severely inconveniencing the traveling public and while providing protection to workers from errant motorists; 4. Cooperation with law enforcement agencies and other affected governmental agencies is a necessary part of the “active management strategies” employed.
