The Highway Design and Maintenance Standards Model (HDM-III), developed by the World Bank, has been used for over two decades to combine technical and economic appraisal of road investment projects, standards and strategies. The International Study of Highway Development and Management (ISOHDM) have extended the scope of the HDM-III model to provide a harmonized systems approach to road management, with adaptable and user-friendly software tools. The new Highway Development and Management (HDM-4) system is the result of the study. HDM-4 Version 2 Provides a powerful system for: • road management • programming road works • estimating funding requirements • budget allocations • predicting road network performance • project appraisal • policy impact studies HDM-4 Applications There are four main areas of application: • Strategic Planning • Roadwork Programming • Project Analysis • Research and Policy Studies Strategy Analysis Used to prepare medium to long term planning estimates of funding needs for road network development and maintenance. Estimates of the medium to long term budget requirements for the entire road network together with forecasts of pavement performance and road user effects can be obtained. The impact of different Budget Scenarios can be estimates together with the Asset Value of the network. Counter Strike 1.6 With Bots All Maps. Dr Dre Back N The Day Rar more.
