| Abstract: | To grasp exactly the traffic flow characteristic of urban road under ice and snowfall conditions,headway distribution of different kinds of urban road was studied.Based on field observation,headway was processed and analyzed under different ice and snowfall conditions.Erlang distribution is used to fit the distribution of headway under different conditions,the validation shows that it is well fitted.It provides theory and data basis for research on the characteristic of traffic flow under ice and snowfall c... |
