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:.

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. Programme Analysis Used to prepare rolling work programmes in which candidate road sections are identified and assigned maintenance or improvement options. HDM-4 calculates the economic benefits and expenditure requirements of each option. A schedule of optimum pavement maintenance and/or road improvement projects which can be carried out within specified budget constraints are identified. Project Analysis Project analysis can be used to estimate the economic or engineering viability of road investment projects by performing life cycle analysis of pavement performance, maintenance and/or improvement effects together with estimates of road user costs. The main outputs include: Annual predictions of pavement performance.

Pavement maintenance and road improvement effects. Road user costs and benefits. Estimates of environmental effects. Standard economic indicators; NPV, EIRR Sensitivity Analysis allows a user to investigate the impact of variations in key parameters on the analysis results. Multi-Criteria analysis (MCA) provides a means of comparing projects using criteria that cannot easily be assigned an economic cost. For example, environmental, social or political impacts.

Research and Policy Studies HDM-4 can be used to conduct a number of road sector policy studies including:. Funding policies for competing needs, e.g.

Feeder versus main roads. Impacts of road transport policy changes on energy consumption. Impact of axle load limits. Pavement maintenance and rehabilitation standards Configuration and Calibration Default data and calibration coefficients can be user defined for any country or region. This allows HDM-4 to be configured to suit the customers’ local conditions and therefore can be applied throughout the world. HDM-4 in Pavement Management Systems By exchanging data with a Pavement Management System (PMS) or other database HDM-4 can utilize existing data to perform an analysis.

The output reports can be adapted to individual requirements thereby integrating HDM-4 into an existing road management framework. HDM-Sentry - A simplified interface for HDM-4 HDM-Sentry operates as a data-preparation tool for HDM-4 which takes user-defined analysis data via easy-to-navigate data entry screens, converts into an HDM-4 compatible analysis file-set and sends the data to HDM-4 where the analysis is performed. HDM-Sentry aggregates the results and presents them as HDM-4 analysis reports.

HDM-4 is a software package and associated documentation which will serve as the primary tool for the analysis, planning, management and appraisal of road maintenance, improvements and investment decisions. The Highway Development and Management System (HDM-4) is a software program originally initiated by the World Bank and extensively used for the appraisal of investments in road transport infrastructure. This application is generally acknowledged by main donor organizations and governments of many countries and, in fact, it has become one of the main tools of decision making in road infrastructure financing. The HDM-4 Version 2.0, the latest version of the program, was developed by PIARC in 2005 and has been maintained by HDMGlobal since.
