Orland Illinois (near Chicago) notorious for grid lock is purposing to use red light cameras, travel signs (estimates travel time to next way-point), and
radar speed monitors (including safety
radar) to improve traffic flow. These systems are operated by community service officers, relieving police from many traffic duties. The systems are hoped to relieve traffic congestion. Also using community service officers is much less expensive than using police.
Chicago has 120 full time community service officers (traffic control aids), and about 800 part time officers. The part timers are usually only utilized for special events (parades, sports, political, large conventions, severe weather etc.).
