Due to the tight schedule, the client had decided
to procure a design and build (D&B) contractor.

to finalise the procurement approach which best fits

The objective of the master plan is to reduce traffic
congestion and pollution through an increase in
public transport mode share to 35-45% of all trips
and a reduction in the private transport mode share
by 30%. A policy to ban motorbikes by 2030 is also
being considered.
Scope of study
Against this backdrop, the World Bank
commissioned Arup in 2019 to carry out an
accessibility analysis on solutions to restructure
the existing bus network to complement the BRT
and rapid transit corridors, therefore providing
an efficient, seamless feeder system and transfer
experience for commuters.
To find out how rail and bus operators can work

high-demand corridors, Arup identified and carried
out three major tasks in this study, including a
network-level accessibility analysis, determination
of highest-priority corridors, and development of
bus route optimisation/reorganisation scenarios.
Network-level accessibility analysis
Arup’s transport experts from Hong Kong, Ho

developed comprehensive guidelines to formulate a
set of bus network options to complement the new
metro lines and improve network efficiency and
