Trends, Policies, Data
The International Transport Forum statistics on investment and maintenance expenditure in transport infrastructure are based on a survey sent to 52 member countries1. The survey covers total investment (defined as new construction, extensions, reconstruction, renewal and major repair) in road, rail, inland waterways, maritime ports and airports, including all sources of financing. For maintenance, the questionnaire covers only expenditures financed by public administrations.
