摘要：

The　paper　analyzed　the　characteristics　of　speed　and　headway　of　vehicles　at　unsignalized　T-intersections　with　4　lanes　on　major　road　and　2　lanes　on　minor　road.　Filed　data　was　collected　at　8　intersections.　It　was　found　the　difference　of　average　speed　of　vehicle　between　traveling　on　outside　lane　and　traveling　on　inside　lane　was　not　clear.　The　85　percent　of　speed　of　vehicles　at　major　approach　waved　near　65.0　km/h.　It　was　also　interested　to　find　the　variance　and　disperse　of　vehicle　speed　did　not　change　with　the　distance　from　approach　to　the　centre　at　intersection.　In　addition,　the　headway　distribution　model　of　left-turn　vehicle　was　built　for　unsignalized　T-intersections.　The　conclusion　was　useful　for　researcher　to　analyze　unsignalized　T-intersections.
