the moment the first vehicle or vehicles reach the upper dam access point,
Tlcsbjr(i,j,km+1)＝Tddln(i,j,km)+60Lsbjr/(Vzxsbjror Vzssbjr)
Tlcsbjr(i,j,km+1) -the moment when the first (batch) vehicle reaches the upper dam access point;
Vzxsbjr-the upper dam is accessed to a road section for heavy vehicle ascending speed limit, km/h;
Vzssbjr-the access road section of the upper dam is heavily driven to descend for speed limit, km/h;
km-the maximum number of control nodes of the road selected by the user from the construction traffic database;
and (3) the traffic flow of each road section in time intervals is translated to each road section on a time axis when the transportation material access point transports the traffic flow in time intervals.
