       Since 2000, Europe and the United States have legislated to impose On-Board Diagnostic (OBD) systems must be installed on the vehicles to monitor whether exhaust emission components are functioning normally. In the fourth phase of Taiwan Emission Standards for Gasoline Vehicles implemented in Taiwan since January 2008, it is also mandatory that all vehicles in the future must be equipped with OBD systems. OBD can monitor the driving conditions in real time, including vehicle speed, engine speed, cooling water temperature, oxygen sensor, etc. If there is a failure of exhaust gas control related components, OBD will generate a fault signal and light up a fault light to remind the driver to conduct vehicle repairs for reducing environmental pollution. Through the OBD, maintenance personnel can detect vehicle failures; environmental protection agencies can detect vehicle emissions, and read vehicle condition data in real time. Therefore, OBD on-board diagnostic system can be used as an important tool for collecting vehicle big data. In order to strengthen the applications of OBD in transportation technology management in Taiwan, this Study intends to conduct a comprehensive discussion on the applications of data collected by OBD in transportation technology management, including the feasibility of applications in traffic management, traffic safety, data application, environmental protection and strategy analysis, to improve the efficacy of transportation industry, use of vehicles and roads as well as the efficiency of energy-conservation, to ensure the appropriateness of policies, and to serve as a reference for the transportation competent authorities to develop relevant scientific and technological management policies.
