Any road expansion must cater transit lane, because in reality, even if you add another lane, the congestion will remain the same for two reasons:
- Klang Valley vehicle sales is very high
- In just few years, congestion will remain the same or even worse
A case study is in Bandar Utama. The overhead bridge on top of highway near Damansara Toll Plaza. It was 2 lanes, then upgraded to 3 lanes. Yet congestion is still chronic. A 2 km section may take 20 minutes just to clear the path which means even lane expansion will not cater traffic growth as well as solving congestion
Government road planning is not known, though from what I gather, they are more interested in building bypass highways such as Damansara-Shah Alam Expresswawy, Kuala Lumpur Outer Ring Road, SKVE and so on.
On Federal Highway, some have suggested to build brand new Federal Highway on top of existing one, which I oppose.
I do suggest road improvement, but it must be planned to cater 20 years down the road, not just expand and end up clogged up in just 2 to 3 years, like what happened to most road projects in Malaysia, save for DUKE which is under-utilised
What I meant was more of a 2 way expansion.
LRT / BRT will reduce congestion. (It may lower the number of cars on the road)
Expansion / New highways will increase the capacity of the roads.
Both are options to reduce traffic congestion, and I believe that it will actually work without the need for COE tax like Singapore.
Its more of the government actually putting this kind of forethought into their planning rather than looking at having small wins to win the heart of the people for election.
