  • GIS-Based Integrated Rural and Small Urban Transit Asset Management System
    Sponsor s partner s Sponsor s U S Department of Transportation About the research Abstract This study developed a methodology for improving the practice of making transit asset investment decisions at state departments of transportation DOTs and local transit agencies The study made four major contributions to the state of transit asset investment decisions First the report provides a review of the literature on the relationship between maintenance preventive and corrective costs and transit vehicle conditions and it discusses its relevance to the vehicle conditions encountered in US transit agencies The maintenance costs include both vehicle operating costs i e fuel consumption oil consumption repair maintenance and depreciation and non vehicle operating costs i e vehicle downtime due to maintenance work and road calls due to vehicle breakdowns on the road The majority of studies in this area find that there are significant differences in vehicle operating costs between road types i e bituminous versus gravel versus earth age mileage and vehicle type Vehicle repair maintenance costs are found to be primarily affected by vehicle condition In terms of non vehicle operating costs vehicle downtime due to maintenance work and road calls due to vehicle breakdowns on the road were extensively studied in relation to vehicle condition The second contribution of the study is the development of a new vehicle deterioration model based on the ordered probit method The major capability of the model is to predict the future conditions of the vehicle based on the historical records of the selected dependent factors such as the vehicle s age mileage current conditions and so forth To best predict the vehicle s future condition the most valuable dependent variables were identified The contribution of possible variables was analyzed and the factors that affect a vehicle s future condition were specified The
