Samenvatting
The report presents the evaluations of the first 18 months of the STEP programs in Sacramento, El Paso, and Chattanooga. The primary purpose of STEP is to demonstrate and evaluate countermeasures designed specifically to reduce motor vehicle traffic accidents. For this purpose, 14 police enforcement countermeasures were designed to be tested in a quasi-experimental environment. To support this effort, additional countermeasures were developed in the areas of public information, traffic engineering, and court procedures. Of the 14 police countermeasures originally established, nine have been tested among the three cities.
