| Abstract: | Based on one week's WIM data provided by Chongqing city expressway development Co.Ltd,the author calculates out 7 kinds of common vehicle type(axle type)aiming at different kinds of vehicle types' appearance probability,and gets loading frequency statistics,curve fitting,function fitting and distribution hypothesis testing to general and partial axle load,finally draws a conclusion that the general axle load(vehicle load)of existing expressway traffic flow in Chongqing city meets the basic requirement. |
