Instead of catch-all pictures of a huge number of cars going by legitimately, the stoplight system is intended to anticipate which vehicles are well on the way to run a red light. That is on the grounds that under the law, the camera needs to catch a driver entering the crossing point after the light is red. So the camera must begin recording before any infraction happens.

1. Running a red light

The primary system framework, which until March was worked by Redflex Traffic Systems Inc., utilizes sensors inserted as a part of the asphalt to foresee possible infringements. At the point when the cars  disregard the sensors specific speed limits, it triggers a camcorder. The city’s new red light camera merchant – Xerox State and Local Solutions Inc. – is settling a citywide change to an over-the-ground radar framework.

A: A vehicle approaches an intersection when the traffic light turns red.

B: If the vehicle is moving above certain speed, a video camera is triggered.

C: The video camera records the vehicle moving through the intersection with the traffic light overhead before it takes a still photo of the license plate (the flash).

2. Reviewing the data, issuing a ticket

Representatives of the red light merchant audit the recordings and figure out if there was an infringement. The information are sent to a second city temporary worker for further audit. In the event that an infringement happened, the second merchant sends the tag number to state powers to recover proprietorship data, and after that the city issues a ticket via mail.

3. Once the ticket arrives

The driver gets a printed reference via the post office, which is additionally posted online alongside the video and photographs. The pictures can be gotten to on the city’s site. Once at the site, a driver must enter the tag number, reference number and city code (CHI) in the proper fields. The recordings are regularly brought down following a while, and the city says it disposes of them following two years. The information at the highest point of the still photos remain.

4. Appealing the ticket

An appeal can be filed by mail or face to face. Each gets relegated to one of around 80 contract legal advisors employed by the city as authoritative law judges.

Did the city put forth its case: The legal counselor utilize a set checklist to determine  whether the city has made its “prima facie” case, which basically asks whether the city committed any errors in issuing the ticket. Do the dates compare? Is the area precise? Does the vehicle make coordinate the tag? In the event that there are any blunders, the legal advisor can toss out the ticket for absence of a by all appearances case.

• The evidence is challenged: The legal counselor peruses the litigant’s case if the offer is sent, or listens to the appealing party’s contentions if face to face. The legal counselor watches the video and makes a finding about whether the “infringement is truthfully conflicting” with the current confirmation. On the off chance that the confirmation does not bolster a finding that an infringement happened, the ticket is tossed out and the appealing party is observed to be not at risk for the $100 fine.
• Keeping a record: In the event that the request was finished via mail, the legal advisor enters the data in the city’s database, which incorporates a clarification of the reasons the ticket was tossed out. For in-person requests, the city holds an audiotape of the hearing, which is open record.
