According to statistics from the Insurance Institute for Highway Safety (IIHS), major cities with red light cameras saw almost 25 percent fewer red light crashes and over 15 percent fewer fatal crashes than cities without red light cameras. Red light cameras are also credited with lowering the instances of side-impact intersection crashes and the serious and fatal injuries that can result from such a crash.
But, all the statistics for red light cameras aren't positive. The IIHS study also reported that intersections monitored by red light cameras tend to see an increase in rear-end collisions by up to 15 percent. The IIHS asserts that rear-end crashes tend to cause less serious injury than do side-impact accidents, making the overall impact of red light cameras positive for drivers, passengers, cyclists and pedestrians sharing the same roadway.
Red Light Cameras In Philly
In Philadelphia, the two most active red light cameras are to the north and south of City Hall, in Center City, namely South Broad and Penn Square; and North Broad and JFK Boulevard. As motorists begin to adapt to these traffic enforcement tools, it is likely that many will begin to stop short or stop suddenly as green lights turn to yellow and then to red. This change in driver behavior is typically what leads to a spike in rear-end accidents at red-light-camera intersections.
Rear-end collisions can lead to serious injury. One of the most common injuries reported by rear-end collision victims are soft tissue injuries like whiplash. Other head and neck injuries are also not uncommon.
