Klang Valley Transport Grid Plan 2025

Klang Valley inherits a highly complex rail and bus network that is subservient to the chaotic highway-oriented land divisions. Adjacent inner suburban pockets branch out from free-flowing roadways, forcing bus routes to mostly straddle along these Kuala Lumpur-bound commuting paths.

The outer suburban pockets too branch out from free-flowing bypasses, creating a natural geometric barrier for an efficient grid-based public transport network. Persisting policies to emphasize new highways and rail expansions to patch up problems resulting from the neglect of the most basic first-last mile necessity further destroys the relevancy of the public transport network in shaping future growth in Klang Valley.

Enter the proposed Klang Valley Transport Grid Plan 2025. The Plan leverages on network synergy of frequent Rapid Transit (RT), highway bus and local bus lines, and each alignment is designed to be as straightforward as possible with respect to access to important urban centres as identified in Klang Valley Growth Strategy 2025.

The frequent grid network is streamlined and optimised to attract private vehicle users to jump to public transport, hence increasing the economic expansion capacity of many already gridlocked urban areas within Klang Valley.


Not all areas can be strategically served by frequent lines due to the geometric constraints carved by car-oriented roadways and land parcels, and hence such areas which produces non-linear bus route patterns are served by timetable-required bus lines. These infrequent bus lines, although have minimal impact on overall ridership and land use shaping goals, are nonetheless critical to ensure equitable and inclusive public transport access to everyone, especially the lower-income households.

The Plan marks a progressive shift from over-dependency on rail as the backbone or trunk and buses as mere feeders, to frequent bus and RT lines as framework for sustainable urban growth in Klang Valley. This Plan suggests implementation of frequent highway buses (Regional Highway Transit), frequent full-length buses and minibuses (Class-C Priority Bus Transit), and open system BRT infrastructure that allows limited branching of frequent local bus lines (Class-B Bus Rapid Transit).

Frequent highway buses, frequent local buses operating on bus lanes, and RT lines serve as metropolitan-level trunk lines that offer faster crosstown and orbital connectivity across Metropolitan Cores and City Centres. On the other hand, frequent local bus alignments are strategically crafted as sub-regional-level trunk lines that not only feed local neighbourhoods to the RT and highway bus lines, but also to nearby urban centres.

All of these frequent bus routes are designed to crisscross each other at urban centres, which means passengers undertaking bus-to-bus and bus-to-rail connections are likely to chain their trips by engaging in additional urban activities (such as shopping and dining), enhancing the areas’ Transit-Oriented Development effects.

These synergistic approaches would also lead towards more balanced passenger load distribution across different directions and different times, which is crucial to ensure public transport operations’ cost-efficiency.

None of these can be realised without implementation of bus-to-rail and bus-to-bus interchange facilities (for the proposed bus-to-rail and bus-to-bus interchange areas that are not presently equipped with conveniently-located bus stops), and implementation of priority measures to give buses special right-of-way lane, traffic signal priorities, road access and turn restriction exemptions over other private vehicle traffic.

Proposals for arterial road and highway bus lanes, and tight local roads to be plied by nimbler, smaller minibuses, can be found on the first map on top of this page. Proposals for other critical priority measures, including specific locations of new bus-to-bus and bus-to-rail passenger interchanges, can be found on the below map.

The integrity of the proposed network (i.e. exact route alignments) together with all of its priority measure components (i.e. right-of-way, road access rights, turn allowances) and pedestrian components (i.e. bus stop locations, bus stop ingress and egress, at-grade bus stop pedestrian access and crossing from all sides of the road or intersections) is to be strictly protected from being negatively impaired by any future road reconfiguration projects.

The Plan also call for an end on construction of new highway corridors within Klang Valley, particularly across the Metropolitan/Conurbation Urban Growth Boundary. This means road infrastructure improvements in the northern and southern fringes (Kapar, Puncak Alam, Batu Arang, Bukit Beruntung, Semenyih, Bandar Baru Bangi, Putrajaya, Dengkil, Saujana Putra and Jenjarom) must not induce new cross-border private transport travel demands.
