Adding more lanes may not reduce congestion at all

Cars on the road

We are all familiar with the reasons why congestion can take a huge toll on our quality of life. Heavy traffic takes up precious time and advances the rate of global warming as pollution rises. But adding more lanes does not help to reduce this problem, as shown by studies on the expansion of highways such as the Interstate 405 in Los Angeles. Instead, constructing more lanes simply paves the way for what experts call “induced traffic demand”.

In land scarce Singapore, we are solving traffic congestion with innovative solutions such as the second-generation Electronic Road Pricing (ERP) system.
