| 摘要： | A description is provided of how decision makers at various levels in Denmark use the output of BELMAN, the pavement management system used on the 4,600-km Danish National Road Network and a large portion of the regional road network. BELMAN helps support political and budget decisions by documenting the need for pavement maintenance and projecting the consequences of budget reductions in terms of the effect on road conditions. BELMAN provides (a) the ability to develop a series of options for maintenance programs and budgets that will be socioeconomically attractive and also ensure a uniform maintenance standard and (b) the ability to project the development of pavement condition several years into the future, on the basis of various budget levels or changes in a variety of other parameters, such as traffic load. The Danish Road Directorate publishes an annual report describing the condition of the national road network, changes over the past 10 years, and projections for the next 10 years. The information about current status and the forecasts for the future are taken from BELMAN's statistical and optimization output. In 1992, this report supported a 15% increase in appropriations for pavement maintenance in the state budget. The same information is also used to support decisions in budget negotiations between the Danish Road Directorate and the 14 county road authorities in Denmark. The state road network in Denmark represents a depreciated value of approximately 7 billion DKK (1.1 billion US$), and the average costs for maintenance have been 300 million DKK (46 million US$) over the past 10 years, with a downward trend in the 1990s. During the same period traffic has increased considerably, especially heavy traffic. With 5% annually, an increasing traffic load is the result of an increased use of super-single truck tires. |
