The gradesof city roads traffic safety are differentiated.Taking Liuzhou asa case, evaluation computation is carried on to deter- mine the gradeof traffic safety of urbanroad.The evaluationresults show that themodel canprovidereliable conclusions, andra- tional qualitative evaluation of urbanroads traffic safety could be done by using thismethod.
