What are the actual costs off building bigger, wider, fast and more roads for Penang: Let’s start by hearing two conflicting and in many ways typical opinions:
1. The Consumers’ Association of Penang
The Consumers’ Association of Penang (CAP) calls on the City Council of Penang Island (MBPP) and Penang State Government to cancel the 1.8km road widening project along Jalan Masjid Negeri to save the roadside trees.
We are upset that consideration is being given to vehicle movement, at the expense of the trees. The roadside trees provide many benefits to us including providing oxygen, much-needed cooling, cleaner air, shade, sound barrier, absorb storm water and also the greenery which gives the road’s distinctive charm and character.
Major changes are underway in Penang. The fast pace of development and priority given to motor vehicles is destroying Penang’s natural charm. With more greenery gone replaced by concrete jungle, Penang will soon become an unliveable habitat. Hence there is a dire need to preserve the character of our tree-lined suburbs and city.
The Penang government should stay true to their word. A Green Penang should be naturally Green. People of Penang must stand up and demand that our greenery, from the hills to the roadside trees, is conserved.
We cannot be silent observers to the wanton destruction of our irreplaceable rich natural heritage in the name of development. We should not give in to crass materialism.

2. Penang Chief Minister Lim Guan Eng
George Town. 18 February. In New Straits Times On-line
Penang Chief Minister Lim Guan Eng is baffled as to why the uprooting of trees for a road widening project along Jalan Masjid Negeri has become “such a big issue.” Commenting on a recent protests by an NGO over a number of trees which are set to be relocated, Lim said other states also do the same thing.
“In other states, they cut down trees or forests and it is not an issue. But in Penang, it becomes a very big issue if we uproot even one tree. “In other states, road widening projects are not an issue but in Penang, it is,” he said, adding that the road widening project was not to make money or benefit any company.
Lim called on NGOs to also protest on matters of national interest and not just on the environment. “Do not be emotional. Be rational. “If you want to protest, show also your concern about the country and demonstrate about political funding,”

But there is more to it than trees
This is not only a Penang story. It is a conflict of understanding, priorities and at the end of the day our behaviour.
The hard fact is that politicians and engineers are hard-wired into an old model. And for this reason they traditionally have had trouble accepting a more encompassing, more strategic approach to sorting out these issues and priorities – precisely because they are trained to look at something else. It’s simply a matter of long-standing professional deformation in both professions.
For the average politician it is important that they seem to be doing something about a problem which gets many complaints and unhappy citizens. Even if the long term impacts make things even worse than before, which is often in the case when your transport policy consists of widening or building new roads in order to solve mounting congestion problems — and in particular with cities in which the growth of automobiles continues to increase.
As to the engineers — and in particular the older ones who were trained in a different time with different constraints — their expertise lies in designing and building good roads. That’s what they learned at university.
And to make it all the harder, there are all those interests who profit from road building, as we saw in yesterday’s Follow the Money article – http://wp.me/psKUY-4z1. They often exert strong pressures on local government with lobbies and relationships that can be hard to resist.
But it does not have to be that way. However in order to get around the corner on this particular problem, both the politicians and their engineers need to look at the issues and choices from the OVERALL strategic situation — which is quite different from the one they are accustomed to seeing. To do this we need to consider the externalities. Let’s have a look.
The trick in getting this right is that they have to alter their key decision criteria, and bring in something called external costs. (More on this at https://worldstreets.wordpress.com/tag/external-costs) .
An externality is a cost or benefit incurred by a party’s decision or purchase on another, who neither consents, nor is considered in the decision. Potential negative externalities (external costs or disbenefits) in transport include:
- increases in traffic congestion,
- induced demand and trip length,
- air pollution,
- water pollution,
- driver behaviour and aggressiveness
- public health costs,
- climate change,
- impacts on nature,
- indigenous culture, tradition and quality of life,
- displaced homes, livelihoods, neighborhoods (communities),
- resource imports,
- family time,
- infrastructure wear and tear,
- policing and enforcement costs,
- equity, etc.
(And somewhere, somehow in all that are those trees.)
That’s quite a long list and if it looks like it is gong to be hard to do, you can relax,: it is. But what we have learned from many painful experiences and lessons over the last half century is that in a democratic society worthy of the name all these factors need to be sought out and taken into consideration.
What this gives us for decision making is nothing less than a radically different, transformative way of thinking about decisions in our sector. An entirely new toolset. Fair-minded politicians and engineers — once they assimilate this new information and the technical procedures that go with them –have shown that they can quickly come around to this different point of view once it has been adequately explained to them .
The good news is that both these important groups have taken this important step in many many cities around the world that are getting the challenges of efficient and sustainable transport right. And the proof is there for all to see in the hundreds of cities world-wide that are showing the way. Thus Penang should be looking at these examples and learning from them.
