Roads are the arteries through which the economy pulses. By linking producers to markets, workers to jobs, students to school, and the sick to hospitals, roads are vital to any development agenda. Since 2002, the World Bank has constructed or rehabilitated more than 260,000 km of roads. It lends more for roads than for education, health, and social services combined. However, while roads bring economic and social benefits, they can also come with social costs such as pollution or deforestation. The Amazon rainforest is crisscrossed by almost 100,000 km of roads—enough to circle the Earth two and a half times. And the transport sector accounts for about 23 percent of global energy-related carbon dioxide emissions and a significant share of local particle pollution. Such tradeoffs need to be weighed when planning any intervention.
How can research better inform transport sector policies? A recent working paper reviewed the academic evidence. The review is organized around a simple model of transport policies and their impacts (Figure 1). Policy makers have three main tools or instruments at their disposal. They can fund infrastructure investments such as building a new road or subway line; they can use price instruments such as taxes on gasoline or subsidies for public transit; or they can issue regulations such as fuel efficiency or safety standards. With these tools, policy makers can affect both the supply and demand for transport, which, in turn, lead to changes in the costs of transport services, accessibility and the magnitude of externalities. These changes stimulate economic responses in terms of trade, location choices or transport use and thus shape the ultimate development outcomes that policy makers seek.
