The project has to be undertaken by Government of Pakistan/ Ministry of Communications as a high priority project as determined by Japan International Cooperation Agency (JICA) in their Feasibility Study conducted for Karachi Transportation Improvement Project (KTIP, 2030) in December, 2012. The Prime Minister of Pakistan, during a high level meeting in Karachi on July 10, 2014, announced to provide infrastructure component to launch the BRT Green Line project on modern lines to alleviate the serve traffic congestion problems in the city and to improve the quality of life of the daily commuters by improving the existing transport system.

Karachi city is passing through an uncontrolled phase of rapid urbanization and motorization. The mitigation of transportation externalities requires a shift towards sustainable transportation system. The city’s present public transport system constitutes a small percentage of total vehicle fleet (4.5%) and serves about 42% of passenger demand yet not dedicated lanes or any other feasible traffic management solution has been provided as compared to private vehicles, which are roughly 36% of the total vehicular traffic but carry only 21% of passengers. The Para-transit mode constitutes 10% of the vehicle fleet and carries 8% of passengers while contract carriages constitute 2% of the vehicle fleet but carry 10% of total passengers (JICA Person Trip Study, 2005).

The main project objectives are defined as under:

To provide reliable, safe, affordable, high quality and fast BRT Bus Service.

To improve the quality of life of commuters in Karachi.

To vastly improve the quality of public transport system in Karachi.

To provide infrastructure that allows buses to ply in an efficient manner with exclusive right-of-way for a significant portion of their route length, and reduce travel time.

Proposed route for Green Line starts from Municipal Park, where a rotary U-turn lane is proposed for buses. The plane alignment extends along M.A Jinnah Road towards northest up to Gurumandir, and after Gurumandir the alignment runs northward along Business Recorder Road, Nawab Siddique Ali Khan Road, Shahrah-e-Shershah Suri and Shahrah-e-Usman passing by some of the major landmarks such as Numaish, Board Office and Nagan Chowrangi.

The Green Line BRT shares the common corridor with Blue line between Muncipal Park and Gurumandir.

This project will constructed a bus-way (dedicated for BRT vehicles) in the median of the roads along the corridor with stations in the center of the median in both at grade and elevated sections which all provide high speed (25 Km/h) and high capacity (29,400 passengers per hour per direction) service. The design capacity of the proposed BRT system with passing lanes provision will increase based on the number of direct / express services run between stations in the future, as required.

The Karachi Strategic Development Plan (KSDP) 2020 described 16 objectives for transport sector, among which following are linked with this project:

Provide safe and efficient mobility for people and goods,Improve public mass transportation system, targeting affordability and convenience,

Strengthen existing transportation infrastructure and services by considering various alternatives,

Evolving a comprehensive transportation plan development and modeling to address vehicular traffic, public mass transportation (bus line and rails based), parking to provide for development of roadway and public transport/mass transit infrastructure development priorities for long range,  andDevelop transport infrastructure to support planned land use changes, especially strengthening links between Central Business District (CBD) and polycentric commercial center nodes.

The Study for Karachi Transportation Improvement Project (KTIP), 2009-2012, JICA, proposed a transport sector master plan up to the year 2030, in which the public transport polices focus on mass transit system such as:

Mass transit system should provide higher services than existing buses in order to satisfy the need of such transit system and promote modal shift from private mode to public one, and Bus Rapid Transit (BRT) should be introduced on major roads.

The Transport Master Plan prepared under the KTIP, 2030 project by JICA proposes the revitalization of Karachi Circular Railway (KCR) on modern lines, 2 Mass Rapid Transit (MRT) lines (Blue and Brown Lines) and 6 BRT lines (Green, Red, Yellow, Orange, Aqua and Purple).

Green Line is one of the busiest corridors proposed by JICA and is planned to connect with Orange Line BRT at Board Office Chowrangi, KCR near Board Office, Blue Line near Gurumandir, Red Line BRT near Mazar-e-Quaid and Yellow Line BRT near Numaish in Saddar.

Green Line and Blue Line systems share the same corridor on M. A. Jinnah Road from Gurumandir to Municipal Park and connect the population centers to the city center.
