A survey conducted for the Taipei City Office of Traffic Control Engineering showed that, since the 1970s, the numbers of bicycles on the roads has fallen gradually. The numbers of motor vehicles in use is increasing rapidly, increasing the pressure on the already crowded roads. Even the traffic management authority has ignored cyclists. No one even bothered to carry out a survey of the number of journeys made by bicycle.
台北市交通管制工程處所做的研究指出，民國六十年代以後，腳踏車交通量所佔比例逐漸下降，快速成長的機動車輛一波波湧進有限的道路空間，連管理當局都忽略了單車族的存在，腳踏車使用旅次的調查也沒人做，都市道路設施早已不適合他們生存。
