Analysis of Accident Types for Intersection Install Red Light Cameras

In this paper, the analysis has been made on the effect of the reduction of traffic accident following the installation of the red light camera. The survey was based on 2004 when the red light camera started on 13 signal intersections in 3 areas to analyze the number of accident occurrences for 2003 as pre-installation and 2005 to 2007 as the post-installation.

Before and after installing the red light camera at each point, the on-site survey was made at the similar points of installed point and un-installed point, and as a result, the average speed of vehicle, dispersion and signal violation rate would be shown to decline at the installed point compared to the un-installed point compared to the pre-installation of the red light camera for average speed of vehicle, dispersion and signal violation rate. This type of result is attributable to have the influence on the safety improvement of the intersection by reducing the signal violation rate with the difference of speed and running speed known to have great influence to the traffic accidents.
