摘要：

An　accurate　evaluation　of　the　effect　of　a　bus　stop　near　an　access　for　an　expressway　on　car　travel　time　on　the　main　road　is　the　basis　for　taking　effective　traffic　management　and　organization　measures.　Based　on　the　traffic　characteristics　analysis　of　bus　stops　and　accesses,　taking　a　bus　stop　located　at　the　upstream　of　an　exit　as　an　example,　a　semi　parametric　proportional　hazards　model　(Cox　model)　was　used　to　analyze　the　association　between　car　travel　time　and　risk　factors.　Survival　probability　of　sensitivity　to　individual　covariates　was　illustrated.　Results　show　that　four　variables　are　significantly　related　to　the　car　travel　time.　The　model　can　be　used　to　precisely　estimate　the　distribution　of　car　travel　time　and　predict　temporal　shifts　in　car　travel　time　due　to　the　change　of　some　factor.　©,　2015,　Beijing　University　of　Technology.　All　right　reserved.
