Considering　the　two　measures　of　information　release　and　congestion　charging　under　uncertain　environment，and　based　on　traffic　network　equilibrium，an　optimal　toll　model　of　the　simple　two-route　road　network　is　derived　and　is　extended　to　the　general　road　network.　Based　on　the　two-route　network，a　day-to-day　route　choice　behavior　experiment　is　conducted.　The　impact　of　the　two　measures　on　travelers’route　choice　behavior　is　analyzed.　The　results　show　that　the　implementation　of　perfect　information　and　congestion　charging　can　both　reduce　the　flow　fluctuation，and　the　effect　of　congestion　charging　alone　is　the　best.　However，only　when　the　two　measures　are　combined，the　trend　of　road　network　flow　towards　user　equilibrium　is　the　most　stable.　Perfect　information　will　increase　route　switching　behavior，　while　congestion　charging　can　effectively　inhibit　large　route　switching.　When　there　is　no　congestion　toll，route　switching　often　increases　the　travel　cost.　On　the　contrary，when　congestion　toll　is　implemented，route　switching　can　often　reduce　the　travel　cost.　The　travel　time　when　the　two　measures　of　congestion　tolling　and　traffic　information　release　are　implemented　together　is　better　than　that　when　the　two　measures　are　implemented　separately.　©　2024　Science　Press.　All　rights　reserved.
