Abstract

The Centralized Local Accident Surveillance System (CLASS), which is being developed by the Traffic and Safety Division of the New York State Department of Transportation to meet federal requirements and to improve highway safety for New York motorists, is described. CLASS includes information about each of the almost 600,000 accidents that occur annually on the 172,000 km (107,000 miles) of public roads in New York and is primarily geared toward meeting the needs of local safety officials, who have responsibility for 148,000 of these kilometers (92,000 miles). The major elements of CLASS are (a) an accident-site-location map produced by interactive graphics techniques and a "link-node" coding scheme, (b) a data base that contains highway information and accident data oriented to the link-node system, and (c) a software system that allows data base information to be accessed, summarized, and analyzed and permits communication between the graphic and nongraphic files. The advantage of a highway safety program based on the concept of interactive graphics is demonstrated.
