Summary This project aims to develop an integrated model that correlates vehicle usage with energy consumption and emissions for evaluating the effects of vehicle ownership and/or usage management strategies on the reduction of energy consumption and emissions. In doing so, based on a total of 5,915 valid questionnaire samples surveyed by this project last year, the project respectively developed nationwide and regional disaggregate choice models of cars and motorcycles, including ownership and usage choice model, type and vintage choice model, and alternative-fuel vehicle choice model. To enhance the applicability of the proposed models, this project integrated all these models to develop a prototype decision making system for proposing and evaluating the management strategies of cars and motorcycles. In addition, to collect ownership and usage panel data of cars and motorcycles for capturing dynamic behaviors, this project further carried out a follow-up questionnaire survey and an expanded questionnaire survey（20,000 expanded questionaires）. We collected a total of 2,860 valid returned follow-up samples with a return rate of 48.35% and 4,811 valid returned expanded questionnaire samples with a return rate of 12.03%. These datasets can be used to develop dynamic disaggregate choice models in the next year of this project. At last, this project also combined Motor Vehicle Exhaust Inspection/Management dataset and questionnaire survey dataset, to develop an integrated correlational model for car and motorcycle emissions. The direct key factors (i.e. vehicle characteristics) and indirect factors (i.e. driver demographics, area in use, and vehicle usage) affecting the emissions of cars and motorcycles have been identified along with corresponding management strategies recommended. Obviously, the purposes of this project have been successfully accomplished. The proposed 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.
