Few transport debates are as contested as the choice between building new roads and expanding public transport. While roads remain essential in some contexts, I largely agree that governments should prioritise public transport, for reasons of efficiency, fairness and sustainability. The most compelling argument concerns congestion. Transport researchers have long observed that new roads tend to generate additional traffic, a phenomenon known as induced demand, so that within a few years the new lanes are as crowded as the old ones. A single train, by contrast, can move hundreds of people in the space occupied by a handful of cars. Cities such as Singapore and Copenhagen have kept traffic manageable precisely by investing in frequent, reliable public networks. Public transport is also fairer. Many young people, elderly residents and lower-income households cannot afford a car, and for them a good bus or rail service determines access to jobs, education and healthcare. Spending on roads, in contrast, mainly benefits those who already drive. Furthermore, transport is one of the largest sources of greenhouse gas emissions in most developed countries. Shifting journeys from private cars to electric trains and buses is therefore one of the most cost-effective ways for governments to meet their climate commitments. Admittedly, rural areas with dispersed populations may still need road improvements, since buses are rarely viable there. Nevertheless, in the towns and cities where most people live, public transport offers far greater long-term value. Governments should therefore direct the majority of new investment towards it.
