LONG-TERM PROJECTION OF HIGHWAY SYSTEM CONDITION

A computer model is described that has been developed by the New York State Department of Transportation (NYSDOT) to predict long-term deterioration and investment impacts on the New York State highway system. The model, the Highway Condition Projection Model, is being used by NYSDOT management to assist in identifying pavement rehabilitation strategies. In the model each section of highway on the New York State system is treated as a separate entity. With a rehabilitation strategy provided by the analyst, the condition and financial requirement are projected for each section of highway for each year for up to 50 years into the future. Deterioration rates determined from empirical data from the New York State highway system and typical costs based on recent construction experiences are applied. The model output is summarized by system, region, and condition. A description is given of how this model may be used to identify sections in need of repair, test alternative rehabilitation strategies, and evaluate the implications of these strategies on long-term condition and funding requirements. The model is operational and is currently undergoing testing and refinement. Applications of the model to NYSDOT's analysis of Interstate funding proposals for highway repair and rehabilitation are described. (Author)
