| Summary | In this project, an integrated model that correlates vehicle usage with energy consumption and pollutant emissions is developed to evaluate the effects of vehicle ownership and/or usage management strategies on the reduction of energy consumption and pollutant emissions. To achieve this goal, the study employed data mining techniques, mainly based on the official (MVO &EPA) database of periodic motor vehicle inspections, to extract key explanatory variables affecting emissions, and to cluster similar vehicle emission types so as to properly set the pollutant parameters and the alternatives vehicle type and age. According to the chosen explanatory variables, clustered vehicle types, and proposed disaggregate, proper questionnaires were designed and a large-scale household survey was conducted. A total of 90,000 questionnaires were disseminated with a total of 6,023 valid questionnaires returned. Based upon these valid returned questionnaires, the proposed models have been successfully calibrated and validated, including ownership and usage models of cars and motorcycles, the type and vintage of cars and motorcycles, and gas mileage regression models of cars and motorcycles. The coefficients of these models are significantly proven with correct signs, suggesting the validity and applicability of the proposed models. These models can be used to facilitate the analysis of the effects of management strategies on the reduction of emissions and energy consumption in the following studies. |
