In　order　to　meet　the　visual　guidance　needs　of　drivers　and　improve　the　traffic　safety　of　foggy　bridges,　a　prevention　and　control　strategy　with　active　visual　guidance　as　the　core　was　proposed.　To　verify　its　safety　efficiency　and　the　impact　on　drivers　in　case　of　emergency　based　on　risk　recognition　process,　the　typical　environment　of　the　E＇dong　Yangtze　River　Bridge　was　considered　as　an　example　and　experimental　tests　based　on　a　driving　simulator　were　performed.　The　results　show　that　the　strategy　significantly　improves　the　drivers＇　psychological　perception　and　behavioral　performance.　When　the　driver　encounters　an　emergency,　the　strategy　can　alleviate　the　urgency　of　the　event　and　reduce　the　risk　of　collision.　The　effect　of　high　brightness　is　better　than　low　brightness.　This　study　realizes　safety　evaluation　of　the　prevention　and　control　strategy,　and　the　configuration　optimization　of　intelligent　guidance　lamps　for　foggy　bridges.　It　provides　a　reference　for　traffic　risk　prevention　of　bridges.
