Flooding, Philippines

• Transportation
The transportation infrastructure in the country is relatively underdeveloped. Partly this is due to the mountainous terrain and the scattered geography of the islands, but it is also the result of the government's persistent underinvestment in infrastructure. In 2003, only 3.6% of GDP went to infrastructure development which was significantly lower than that of some of its neighbors. Consequently, while there are 203,025 kilometers (126,154 miles) of roads in the country, only around 20% of the total is paved.
Nevertheless there are many ways to get around, especially in urban areas. Buses, jeepneys, taxis, and motorized tricycles are commonly available in major cities and towns. In 2007, there were about 5.53 million registered motor vehicles with registration increasing at an average annual rate of 4.55%. Train services are provided by three main railway networks that serve different areas of Metro Manila and parts of Luzon: the Manila Light Rail Transit System (LRT), the Manila Metro Rail Transit System (MRT), and the Philippine National Railways (PNR).
As an archipelago, inter-island travel via watercraft is often necessary. The busiest seaports are Manila, Cebu, Iloilo, Davao, Cagayan de Oro, and Zamboanga. Passenger ships and other sea vessels such as those operated by Superferry, Negros Navigation, and Sulpicio Lines serve Manila, with links to various cities and towns. In 2003, the 919-kilometer (571-mile) Strong Republic Nautical Highway (SRNH), an integrated set of highway segments and ferry routes covering 17 cities was established.
