Small City Traffic Improvements Developed from Accident Analysis

IN T R O D U C T IO N It is my opinion that the success or failure of our street operations can be measured in two ways. First is the effect on operations, which can be checked by travel time or delay studies at particular intersections. The second method is the use of accident data. Examples of actual findings of traffic improvement needs, developed directly from accident report analysis, have been gathered from five cities in Illinois. These are in the small category, ranging from 6,500 to 60,000 population. There are two broad categories of improvement needs that can be developed from accident analysis. One involves control devices, while the other involves physical changes.
