According　to　the　traffic　flows　data　collection　of　radial　roadways　in　Beijing,　this　paper　quantitatively　analysis　the　characteristics　of　reversible　traffic　congestion　using　the　factors　of　traffic　volume　and　mean　speed.　Based　on　the　analysis　of　reversible　traffic　congestion,　we　propose　some　measures　for　improvement,　including　reversible　guided　lane　at　intersection,　reversible　guided　lane　on　road　segment　and　split　phasing　etc.　,　which　are　testified　by　traffic　simulation.　This　study　provides　the　practical　guidance　to　resolve　the　Reversible　traffic　congestion　and　emergency　evacuation　in　Beijing.
