ACCIDENTS AND DEATHS ON INTERSTATE ROADS COMPARED TO US AND STATE ROADS IN TEXAS
The object of this study was to discover what differences exist betweem Interstate highways and U.S. State highways with respect to speeds, involvement rates, and death rates. Models developed for each highway system, when tested with collected data, produced an irregular pattern of errors in prediction of both accidents and deaths, while the aggregate model showed errors as expected, increasing in magnitude in rough proportion to the distance from the base year. The authors conclude that the data collected was not of sufficient quality to withstand disaggregation, because of incongruities due to collection by different agencies using different bases for collection and reporting.
