Libya has suffered forty-two years of neglect with a deficit in management and development in its transportation infrastructure. That deficit comes from a scarcity of data, and the current poor approach in the country to developing its transportation infrastructure management system. As the first step to help the government of Libya rebuild itself, this project will conduct a full inventory of its facilities for a plan to manage and rebuild their network of roads, ports, and streets, which is one of the most important infrastructure features in the country. The main purpose of this project is to help Libya's government reduce and manage this deficit by using GIS technology to compile and manage spatial data on its transportation infrastructure. Those data will be managed in a geodatabase to produce a basemap with a series of layers, such as road centerlines, railroads, administrative boundaries, facility sites, streams and lakes, and building footprints. In addition, that basemap will be used to produce a sample application for a transportation infrastructure use case.

This paper evaluates the management of urban transportation infrastructure in Nigeria. It does so by defining transport infrastructure to include both the locative and distributional role of transport. The argument is general because transportation is similar in most cities, except in Lagos and Abuja with greater coordination and control. Nigeria's urban transportation is driven by the private sector, and should be regulated, but it is not. There is confusion in its management partly because the sector is in the jurisdiction of state and local government thereby constraining full federal intervention, as all tiers of government perform different functions in the sector. Excessive traffic demand is choking most cities even when car ownership is moderate due to poor city structure and narrow roads. Further increased traffic demand is expected in over 23 cities by the year 2030. Reforms are therefore needed to introduce economic regulation, corporatize public transportation, and adopt transport demand management measures in most cities. The creation of the Lagos Metropolitan Area Transport Authority LAMATA is highlighted as a model which other cities could adapt as an institutional framework for economic regulation and the management of transport demand. Keywords: urban transportation, infrastructure, transport demand, economic regulation

Testimony issued by the General Accounting Office with an abstract that begins "As Congress considers reauthorizing the Transportation Equity Act for the 21st Century (TEA-21) in 2003, it does so in the face of a continuing need for the nation to invest in its surface transportation infrastructure at a time when both the federal and state governments are experiencing severe financial constraints. As transportation needs have grown, Congress provided states--in the National Highway System Designation Act of 1995 and TEA-21--additional means to make highway investments through alternative financing mechanisms. A number of states are using existing alternative financing tools such as State Infrastructure Banks, Grant Anticipation Revenue Vehicles bonds, and loans under the Transportation Infrastructure Finance and Innovation Act. These tools can provide states with additional options to accelerate projects and leverage federal assistance--they can also provide greater flexibility and more funding techniques. Federal funding of surface transportation investments includes federal-aid highway program grant funding appropriated by Congress out of the Highway Trust Fund, loans and loan guarantees, and bonds that are issued by states that are exempt from federal taxation. Expanding the use of alternative financing mechanisms has the potential to stimulate additional investment and private participation. However, expanding investment in the nation's highways and transit systems raises basic questions of who pays, how much, and when."

"The transport infrastructure generates benefits in efficiency and interchange of goods and people. The increase of accessibility induced by transport infrastructure in a region causes employment growth, which causes a more positive economic future for the affected area by the infrastructure. The purpose of this book is presented to the practitioners, researchers and students as a comprehensive framework around the transport infrastructure for the following: i. Transport infrastructure, their economic influence and the territorial transformation. ii. The active mobility infrastructure, the design and the habitat influence in urban areas. iii. The fundamentals and main approaches around road infrastructure and pavement management. iv. The fundamentals and main approaches around road infrastructure, pavement design, assessment and management in road and airport pavement. v. An approach toward the assessment and management of railway infrastructure and the urban policies of tram systems in Europe. The transport infrastructure diversity presented in this book offers a valuable and representative point of view concerning its importance, considering the assessment aspects, management and especially the challenges in the field."--Provided by publisher
