This brief talks about achievingsustainable financing for urban transport in developingcountries.The state of urban travel in many developingcountries is grim. Congestion and low-qualityinfrastructure, including limited network coverage and poorroads and sidewalks slow travel times, which slows economicdevelopment. Lower-income residents rely the most on publictransport and bear a disproportionate share of the burden ofits failures. The low quality of urban public transportsystems in developing countries indicates a chronicfinancing gap, underfinancing for capital investments,operations, and maintenance. Though urbanization is animportant ingredient in poverty reduction, it inevitablystrains urban transport, so it is widening the financinggap. World Bank research released this year has pinpointedsources of the financing problem and proposed a responsebased on the concept of, "who benefits, pays." Bytapping into innovative revenue sources that promoteefficient pricing, increase overall revenue, and strengthenall elements of sustainable transport, urban areas indeveloping countries can fund a wide variety of urbantransport projects in a manner that will ensure theirsustainability. To conclude, by combining appropriatefinancing instruments and focusing on the “Who benefits,pays” principle, overburdened urban transport systems can berevived with wise and sustainable investments to covercapital, operation and maintenance of all parts of atransport system,“from the sidewalk to the subway.”
