Glare　seriously　affects　the　quality　of　tunnel　lighting,　and　also　has　a　negative　impact　on　drivers’　visual　recognition　in　the　tunnel.　By　introducing　the　calculation　method　of　glare　influence　level　G　and　relative　threshold　increment　TI,　the　article　uses　DIAlux　evo　lighting　simulation　analysis　software　to　simulate　and　analyze　the　tunnel　lighting　glare　of　different　installation　spacing　and　angle　combinations　under　the　condition　of　Symmetrical　lighting　on　both　sides　in　the　tunnel.　The　influence　range　of　glare　produced　by　different　installation　spacing　and　angle　combinations　under　symmetrical　lighting　is　obtained.　The　research　results　show　that:　in　the　symmetrical　lighting　mode　on　both　sides　of　the　tunnel,　when　the　angle　between　the　driver’s　sight　line　and　the　incident　direction　of　the　tunnel　lighting　is　less　than　82.38°,　the　lamps　will　produce　glare　to　the　driver.　When　the　glare　influence　level　of　symmetrical　bat-wing　tunnel　lamp　is　between　1　and　3　at　any　installation　distance　and　angle　under　the　symmetrical　arrangement　of　lights　on　both　sides,　it　is　a　serious　glare　effect.　©　2021　IOP　Conference　Series:　Earth　and　Environmental　Science.
