Claim 2:
3. The method for evaluating road safety based on multi-dimensional influencing factors according to claim 2, wherein step B further comprises: based on the historical traffic data of the sub-region within the preset duration and the historical traffic data of each traffic road in the sub-region within the preset duration, obtaining, for each traffic road corresponding to the sub-region according to the following formula:, T
  =
  
   {
   
    
     
      
       1
       ,
