The　recurrence　of　traffic,　environment　and　traffic　accident　scenery　on　the　road　is　significant　to　research　traffic　flow,　road　and　traffic　safety,　which　could　provide　＇humanization＇　of　road　safety　traffic　system　with　safe,　economic,　repeatable　and　ideal　experiment　platform.　Drivers　are　direct　users　and　key　factors　in　the　safe　road　traffic-system.　Road　traffic　human-computer　interface　simulator　experiment　system　includes　driver　experiment　system,　vehicle　experiment　system,　traffic　flow　experiment　system　and　road　environment　and　weather　condition　experiment　system.　The　system　can　gather　and　analyze　the　data　of　drivers,　vehicles　and　road　(environment)　constantly　and　maintain　the　system　data.　Traffic-flow　characteristic,　running　speed,　vehicle　operation,　operation　characteristic,　physiology　and　psychology　characteristic　of　drivers　are　also　gathered　and　reappeared.　The　experiment　system　hardware　includes　driving-simulator　system　and　driver　physiology　and　psychology　detect　apparatus.　©　2010　IEEE.
