Sustainable Transportation and Singapore:

A couple of weeks ago, I completed a term paper for my Philosophy of Geography class. I did research on Transport Geography (a sub-discipline in Geography) and found many groundbreaking transportation ideas from the literature. This post will feature one segment of my paper which explored Singapore and the successes it has had in achieving a sustainable transportation system. Good transportation systems will be key for the 21st century, especially for climate change mitigation.

This is a pretty lengthy post. For anyone wishing to read more about transport geography, you can access my paper here.

A general trend in Asian countries like India and China is that increased wealth means more production and subsequent purchasing of automobiles. This process is problematic from a socio-economic status perspective as more vehicles are being purchased and used by the wealthy which exposes the poor to even more emissions and pollutants, or as one scholar puts it: “mobility for some will be at the expense of immobility and disease of others”. It is difficult for the government to discourage automobility when mobility is perceived to be better and public transit might be unpopular because it is uncomfortable, dirty, inconvenient and less enjoyable.

The critical challenge is to balance motorization with public transit. Singapore has been successful with such an endeavour through bringing about a sustainable transportation system. Their system fosters mobility because it allows users to choose their mode of transportation subject to a range of well-coordinated policies to control car population and usage, and at the same time to provide high quality public transport facilities.

Roads have received substantial public investment; from 1986 to 1996 the road surface area increased 27%. Between 1996 and 2000 $3 billion was invested to construct a 300 km highway and from 2001-2005, another $570 million was used to further road expansions. Public investment in the public transit network has occurred simultaneously through the mass rapid transit (MRT) and the Light Rapid Transit (LRT) networks.

Promoting motorization and public transit has involved a set of innovative management policies to achieve a sustainable transport system. The first is a vehicle quota system (VQS) which combines state planning and market mechanisms to allocate vehicles to users and so manage the vehicle population. This management tool is effective in controlling the vehicle population in Singapore as it limits car ownership. Ownership of a vehicle requires a certificate of entitlement and the quota system is based on categories of vehicles differentiated by engine size. The VQS has reduced the annual growth rate of vehicles to three percent because citizens feel inclined to have more control over their transportation choices either through walking, busing, cycling etc.

The other innovative policy is road pricing. The country uses electronic road pricing (ERP) which is a sophisticated combination of radio-frequency, optical-detection, imaging and smart-card technologies. ERP is a method of intelligent transportation systems (ITS) which has gained popularity in places such as North America, Europe and South-East Asian nations like Singapore. These technologies have been championed by civil engineers but have required input from transport geographers and planners in terms of situating them in transportation networks. Pricing roads is a really effective approach to discouraging automobility.

With ERP, the share of private cars over total commuters declined from 48% to 29%. Public transportation has received many benefits from the ERP scheme. Indeed, buses have become faster, more efficient and have seen ridership rates go up. Singapore was the first city in the world to implement an electronic road toll collection system for purposes of congestion pricing.

Mobility has been advanced in Singapore because policies have promoted public transit. Policies have made the quality, frequency and diversity of the public transit system and its services a viable alternative to the car for a wide array of the population. One progressive and emerging idea is to install intelligent traffic lights to detect approaching buses so the lights turn green automatically, this will also come with more bus lanes. This is meant to increase efficiency and mobility as a bus carries more passengers than an automobile.

Low fares in Singapore’s rapid transit system ensure that anyone can access public transport. Low-income commuters are assisted by the “many helping hands” approach, with the government, local communities and the public transport operators all extending their help in various ways such as government income redistribution schemes and transport vouchers. The rapid bus transit system provides low fares in general and continuously seeks input from the public about quality of service, price level, waiting and walking time in a trip. Last, road pricing has been effective because it controls usage of cars i.e. making automobility less attractive because it is more expensive and rapid bus transit more popular because it is cheaper and highly efficient.

Key message: Singapore provides a model for an excellent transportation system. While many cities and countries have their own unique geography, economy and public policies- there is always ample room to revamp transportation systems insofar as the political will is in place.
