Adams can aim and zoom video cameras throughout the city and adjust the timing of traffic lights from his control center. Luckily, there's no conflict of interest between the two. Taking the city out of the loop means replacing old technology with new. The loop is the buried wire at intersections that triggers stoplights to turn green and to keep traffic moving.
Cameras are low-maintenance and more reliable than a loop.
When the camera detects a car, it notifies the main computer at Adams' office that there's traffic at the intersection. Many of the city's loops are in need of replacement. Around the mall area, there's a lot of loops in the road going bad. Wire loops are sensitive to metal, not weight, as is commonly believed. Roll the old Chevy over the loop, which is embedded an inch deep in the roadway, and the car's metal triggers an electrical impulse.
