Although countries in the Bank's six regions differ in many ways, their priorities for transport consistently show some common challenges. Examples include road infrastructure, urban road congestion, road accidents, basic connectivity to transport systems for rural communities, climate change implications. These priorities all point to a strategy that will make transport cleaner, safer, and more affordable.
The energy efficiency of specific transport modes is crucial because virtually all measures that increase the efficiency of energy use will reduce greenhouse gas emissions per unit of transport: in other words, they can permit the benefits of transport to be sustained while making it more climate-friendly.

In low- and middle-income countries road networks are increasing in length, on average, by about 2 percent a year. Although some networks appear relatively slow growing or static (particularly in LAC), others are growing rapidly, in particular India (at 4 percent a year) and China (at 6 percent a year).

| The Bank Group's lending for railway projects has significantly increased over the past five years. This higher level of engagement is proposed to continue, reflecting the strategic intention to grow a more diversified transport portfolio that addresses transport-for-trade needs and which would also give greater emphasis to public transport service and to energy efficiency. | Â |
