Eco-driving　behavior　has　been　treated　as　one　of　the　most　cost-effective　way　in　reducing　vehicle　fuel　consumption　and　emissions.　In　this　study,　the　effects　of　eco-driving　training　on　different　driving　behaviors　in　start,　stop,　speed　choice　and　no-idling　from　different　levels　of　training,　from　receiving　only　static　information　(EDUCATION)　to　guided　practicing　(COACHING　after　EDUCATION),　were　thoroughly　evaluated　and　compared.　The　drivers＇　comprehensibility　with　eco-driving　information　was　examined　through　eco-driving　questionnaire　surveys.　The　results　indicated　that　EDUCATION　alone　was　effective　to　improve　driver＇s　comprehensibility　with　the　basic　concepts　of　eco-driving,　to　reduce　the　percentages　of　vehicle　idling　and　to　help　drivers　to　avoid　rapid　starts　slightly.　EDUCATION　alone　did　not　significantly　improve　the　driving　behaviors　of　stop　and　speed　choice,　while　COACHING　after　EDUCATION　was　found　to　enhance　the　effectiveness　of　these　two　elements　of　eco-driving.　COACHING　after　EDUCATION　did　not　introduce　much　additional　benefit　for　more　fuel-efficient　starting　pattern.　In　addition,　eco-driving　training　led　to　more　consistent　driving　behavior　as　evidenced　by　smaller　standard　deviation　values　on　all　measures　related　to　fuel　efficiency.
