Now regular PMPML buses ply on the Hadapsar-Katraj corridor of BRTS. Total of 112 kilometres (70 mi) route was proposed for Rainbow BRTS. The funding for the project came from the Government of India under the Jawaharlal Nehru National Urban Renewal Mission. Most of these buses are not in service currently. The Hadapsar-Katraj pilot project consisted of 16.5 kilometres (10.3 mi) of bus lanes along the Pune Satara Road using airconditioned, low-floor more than 500 Volvo B7RLE buses initially on Katraj - Swargate - Hadapsar. PMPML started plying pilot routes in December 2006. Pune was the second city in India to experiment with a bus rapid transit system, after Ahmedabad, which opened the nation's first BRT in 2010. Additionally, specific components of the project in PCMC limits are being funded under the ‘Sustainable Urban Transport Project’, which is an initiative of the Ministry of Urban Development, Government of India and is supported by The World Bank, UNDP & GEF.

The Rainbow BRTS project is being implemented with the financial support of Jawaharlal Nehru National Urban Renewal Mission (JnNURM) of the Government of India. The project currently envisages 113 km of dedicated bus corridors along with buses, bus stations, terminals and intelligent transit management system. The infrastructure has been developed by the Pune Municipal Corporation & Pimpri Chinchwad Municipal Corporation, Pune. The system is operated by the Pune Mahanagar Parivahan Mahamandal Limited (PMPML). Rainbow BRTS is a bus rapid transit system in the city of Pune.
