In mass accident data systems, the quantity of data is traded against depth of data to control cost. Mass data provides perspective by showing how much actual improvement is attributable to a countermeasure and evaluating effectiveness against cost. Two mass data systems, the Cornell Automotive Crash Injury Research (ACIR) project and the North Carolina accident data system, are described, and the essential features of a good data system are indicated. A good data system should be responsive to all phases of the problem. Full cooperation of police is essential. The system should use a multilevel reporting capability and be able to accommodate additional sampling to obtain needed special information quickly. It should provide for training of reporting officers as to specific data requirements and provide for feedback through some kind of publication. The crash classification should be reviewed to be sure it does not rule out certain analyses just because of its internal characteristics. Data should provide an indication of crash severity, such as by means of a vehicle deformation scale. The system should provide for at least crude injury data on all injured parties, and a means to obtain samples of detailed injury. It should consider ways of storing and retrieving the investigating officer's narrative. Through retention of key identifying numbers, the system should lend itself to linkage with other data files. Crash locations should be precisely identified so as to relate crashes with roadway features. The system should provide for acquisition of appropriate exposure data, and for very good analysis capability.
