Automated　vehicles　equipped　with　adaptive　cruise　control　systems　(ACC-AVs)　are　prevalent　and　the　ensuing　issue　is　the　feasibility　of　ACC-AVs＇　operation　on　the　roads.　This　study　investigates　the　feasibility　of　road　horizontal　curve　designs　for　ACC-AVs　from　a　vehicle　dynamics　perspective.　Following　the　scenario　generation　framework,　we　created　and　tested　several　scenarios　featuring　horizontal　geometric　elements　and　design　speeds,　conducting　a　safety　evaluation　based　on　the　critical　adhesion　coefficient,　lateral　acceleration,　lateral-load　transfer　rate,　together　with　driving　comfort　indicators.　Results　indicate　that　ACC-AV　can　navigate　on　road　curves　designed　with　a　common　minimum　radius　(Rmin_com)　effectively　at　speeds　over　60　km/h,　comparable　to　conventional　vehicles.　However,　both　Rmin_com　and　limited　minimum　radius　(Rmin_lim)　designs　show　limitations.　Additionally,　the　feasible　radius　ranges　for　ACC-AV　reveal　the　capability　to　safely　handle　sharper　curves　and　maintain　higher　speeds,　suggesting　potential　for　adaptable　road　design　in　complex　environments.　Finally,　minimum　radius　ranges　were　summarized　for　ACC-AV　safe　and　comfortable　operation　on　road　curves,　unveiling　the　potential　risks　and　reminding　designers　in　curve　design　controls　for　ACC-AVs.　©　2024　American　Society　of　Civil　Engineers.
