Different　waiting　time　at　the　intersection　and　different　road　alignments　can　evoke　different　emotions　of　the　driver.　Emotional　space　of　the　driver　is　established　in　the　paper.　The　emotional　space　consists　of　four　factors,　＇Happy＇,　＇Angry＇,　＇Relief＇,　and　＇Nervous＇.　Suppose　that　the　waiting　time　only　cause　the　change　in　the　direction　of　vertical　axis　on　the　emotional　space　and　the　horizontal　radius　of　road　only　cause　the　change　in　the　direction　of　horizontal　axis　on　the　emotional　space.　Emotion　model　of　the　driver　is　proposed　based　on　fuzzy　logic.　The　simulation　example　proves　the　feasibility　of　the　proposed　model.　The　results　show　that　different　waiting　time　and　different　road　radius　can　evoke　different　emotions　and　the　emotion　of　drivers　should　be　considered　when　the　signal　timing　is　calculated　at　the　intersection　in　order　to　avoid　traffic　accidents　because　the　strong　emotion　states,　e.g.　angry,　have　potential　to　endanger　driving　safety.　©　2009　IEEE.
