Traffic safety studies in smaller communities.

Accident information provided by police reports are utilised to accomplish an accident location file. When the file has been established, data may be extracted for the following uses. 1. To forecast accident rates as related with various kinds of routes or types of accidents. 2. To identify locations having higher rates than the expected average. 3. To isolate patterns of accidents which can be corrected by traffic engineering efforts, and to compare needs among different locations in order to assign improvement priorities. 4. To perform before- and-after studies on the effect of changes in controls or geometric design.
