Back in July of 1991, when training was still six weeks, for visitation day for the camp's 12,000 trainees, there were 60,000 visitors, 20,000 cars, and 400-plus buses. This created a tremendous traffic jam on the highway. Since then, the training period has been shortened, so the number of visitors has dropped considerably.
以民國八十年七月為例，受訓學生有一萬二千名，懇親會當天共有六萬多民眾、二萬輛小汽車、四百多輛大客車，湧進成功嶺，造成高速公路彰化至王田，后里至豐原南下北上車道大塞車，後來受訓時間越縮越短，探親的人便減少了許多。
