I remembered that the calculation result of 3 aspect for stopping train is bigger than Required Headway Time/110%, but less than the Required Headway Time. So I am confused about whether to use 3 aspect or 4 aspect. Finally I decided to use 4 near junction,3 aspect in other area, but time is tight, I do not have enough time to think how to arrange the transition of 4-3aspcet and 3-4 aspect, so I used 4 aspect almost in all main line....
