To　explore　the　influence　of　bridge　wind　barriers,　with　their　specific　opening　shapes　and　arrangements,　on　bridge　deck　wind　fields　and　vehicle　driving　stability　under　different　crosswinds,　five　bridge　wind　barrier　schemes　were　designed.　For　two　incoming　wind　speeds,　the　wind　speed　at　different　heights　over　three　traffic　lanes　and　the　aerodynamic　six-component　force　of　the　vehicle　model　were　measured,　and　the　influence　of　the　wind　barrier　parameters　on　the　vehicle　driving　stability　was　analyzed.　The　equivalent　wind　speed　reduction　coefficient　of　the　wind　barrier　was　compared　with　the　dimensionless　coefficients　of　the　aerodynamic　side　force,　roll　moment,　and　aerodynamic　lift　to　verify　the　accuracy　of　the　shielding　effect　evaluation　indices.　The　final　conclusions　provide　a　useful　reference　for　designing　bridge　wind　barriers.
