Abstract：

Road　environment　monotony　is　a　critical　exogenous　cause　of　driving　fatigue.　According　to　the　definition　of　monotony,　the　MPEG　compression　technique　was　used　to　obtain　the　change　of　road　environment　and　the　related　parameters　of　this　technique　were　discussed.　Considering　drivers＇　most　meaningful　information　(MMI),　the　driver　observation　region　was　divided　into　three　regions.　Each　region　was　given　a　different　weight　based　on　gazing　time　(or　gazing　frequency),　and　the　new　method　of　road　environment　change　calculation　combined　with　drivers＇　observation　region　was　introduced.　The　mean　of　environment　change　was　considered　as　the　road　environment　monotony　measurement,　and　the　location　identification　method　of　road　environment　larger　change　(or　stimulation　points)　was　given.　The　method　of　evaluating　the　road　environment　has　been　proven　to　be　feasible　in　the　in-field　experiment.　It　is　also　the　basis　of　researching　road　environment　monotony　levels　and　monotony　improvement　countermeasures　in　the　future.　©　2010　ASCE.
