Because greenhouse gas emission continues to increase, prompting the global temperature to rise. In recent year, all countries around the world promote the concept of energy saving and carbon emission reduction. To improve masses willing of taking public transportation, decrease vehicle emissions, and energy consumption, Intelligent Transport System (ITS) integrates related information and communications technologies to provide useful information to user. The paper introduces two intelligent transport system projects, namely highway bus information and management system and taxi fleet dispatching and management system. Vacancy rate, idle time, and speed are performance metrics to evaluate the two systems. Statistical results show that highway bus information and management system reduces the tens of thousands kiloliter oil consumption and the tens of thousands tons CO_2 emission every year; the other system reduces 505 kiloliters oil consumption and 1142 tons CO_2 emission for a taxi operation.
