Based　on　the　statistical　analysis　of　Beijing　urban　development　level,　this　article　puts　forward　the　principles　for　selecting　the　indicators　of　urban　development　level.　It　creates　an　integrated　indicator　system　for　urban　development　level　consisting　of　16　indicators　in　three　aspects-social　development,　transportation　supply　and　transportation　demand.　Also　this　article　establishes　indicators　for　macroscopic　road　network　operation　based　on　road　network　congestion　index　(CI)　and　arterial　network＇s　peak-hour　travel　speed.　By　gathering　the　actual　statistics　data　of　Beijing　during　the　year　2003-2009,　it　identifies　the　input　indicators　for　the　relations　model,　establishes　the　relations　model　between　urban　development　level　and　road　network　operation　using　the　＇Partial　Least　Square　(PLS)　method＇.　The　relation　model　is　validated　by　using　the　existing　data.　The　result　shows　that　the　model＇s　precision　is　within　10%,　being　able　to　satisfactorily　meet　the　need　of　actual　use.　The　research　model　in　this　article　can　provide　important　support　for　Beijing＇s　future　urban　transportation　development　decision-making　and　transportation　development　strategy.
