As　a　basic　industry　in　the　country＇s　development,　the　transportation　industry　has　a　significant　relationship　to　its　normal　operation　for　developing　and　constructing　the　national　economy.　The　increase　in　carbon　emissions　from　transport　is　an　increasingly　growing　problem,　and　countries　worldwide　are　also　taking　measures　to　reduce　emissions.　Using　time　series　data　over　the　period　from　1990　to　2016,　this　paper　applies　the　visibility　graph　approach　to　transform　it　into　a　complex　network　and　excavate　some　information　about　the　data,　then　evaluates　all　countries　based　on　the　TOPSIS　method.　We　find　that　the　development　of　transportation　is　an　important　symbol　to　measure　the　degree　of　modernization　of　a　country＇s　transportation,　and　low-income　countries　have　lower　carbon　emissions　due　to　slower　transportation　development.　The　results　of　transportation　carbon　emissions　are　especially　encouraging　for　the　Chinese　government　given　its　long-term　and　sustained　efforts　to　expand　railway　and　waterway　infrastructure,　and　provide　a　new　perspective　for　further　research　on　the　development　trend　of　global　transportation　carbon　emissions.　Meanwhile,　it　is　urgent　to　speed　up　the　development　and　use　of　clean　energy　for　economically　developed　countries.
