Traffic Control Using Cameras at Huntington Mall
The LEGO Dacta Transportation Units for the Programmable LEGO RCX brick include doing research on area traffic intersections. Bruce E. Kenney III, P.E. Traffic Services and Systems Management Engineer of WV DOT helped us out with information on the intersections at the Mall.
Way over there on top of the light is a camera.
Inside the box is the computer that controls the lights.
Control system
The areas where cars pass are monitored for changes in light
and dark. That input information is used in the computer program to determine the time for the green, yellow, red, and turn lights.
There is an astonishing amount of wire, switches, and electronic
components.
That "small" looking camera is NOT small.
It is hard to imagine the camera is so large. It needs to be placed high up to get a clear view over large vehicles.
Information from one intersection is sent to the other intersections.
