On Friday 29 May 2015, twelve delegates from the Asian Development Bank (ADB) Board visited the Lanzhou BRT, with ITDP-China invited by the Lanzhou ADB PMO to lead the site visit. Local, provincial and national officials also joined the visit, including from the city government, Ministry of Finance, and Gansu Province Department of Finance. City officials included the Vice Mayor, Anning District Director, Development and Reform Commission, ADB Project Management Office, Bus Company, and others – in total representatives of 20 city government departments. ADB participants included the Executive Board members from Australia, Canada, the United States of America, Korea, Pakistan, Italy, India, Malaysia, and China, along with the head of the ADB's China office.

Xianyuan Zhu from ITDP-China led the site visit and provided on-site briefings to the delegates regarding Lanzhou BRT’s planning, design, implementation, and integrated bike sharing system. She also showed the delegates "before" and "after" photos of the Lanzhou BRT corridor, and explained the impact analysis work and results. The delegation took the BRT to visit Qiaobei, Peili Guangchang, Feijiaying and Liujiapu BRT stations, a bike sharing station, an underground shopping mall built together with the BRT, and the BRT control center. The ADB Board members were very interested and asked a lot of questions during the site visit, regarding for example the "directional" stations, direct service operation, enforcement of BRT lanes, and access by people with disabilities. David F. Murchison, Canada Executive Board member, commented: "The Lanzhou split [directional] BRT station is very good. It can reduce new fleet purchase requirements, and should be applied in other cities."
