Roads Economic Decision Model (RED) (Link to the RED page of the SSATP website)
3.206/042,689 KbThe Roads Economic Decision Model (RED) was developed under the Road Management Initiative (RMI), a key component of the Sub-Saharan Africa Transport Policy Program (SSATP) aiming at improving the decision-making process for the development and maintenance of low-volume roads. The model performs an economic evaluation of road investments options using the consumer surplus approach and is customized to the characteristics of low-volume roads such as a) the high uncertainty of the assessment of the model inputs, particularly the traffic and condition of unpaved roads; b) the importance of vehicle speeds for model validation; c) the need for a comprehensive analysis of generated and induced traffic; and d) the need to clearly define all accrued benefits. RED computes benefits for normal, generated, induced, and diverted traffic, and takes into account changes in road length, condition on the dry and wet seasons, geometry, surface type, and accident rates. Users can add to the economic analysis other benefits or costs such as social benefits and environmental impacts, if computed separately. RED is setup on a series of Excel 2000 workbooks, which collect all user inputs and present the results on an efficient manner, performing sensitivity, switching values and risk analyses. The current version of RED (Version 3.2), released in July 2004, is available in English French, and Spanish, has a new module designed to estimate vehicle operating cost using the HDM-4 relationships, permits the characterization of the traffic of the dry and wet seasons separately, and includes a budget constraint optimization and multi-criteria analysis - read more about the new features of Version 3.2. For more information about RED, read the Africa Transport Technical Notes, Note No. 18 titled "Roads Economic Decision Model (RED) for Economic Evaluation of Low Volume Roads."

The Highway Development and Management System - HDM-4 - is a software system for investigating choices in investing in road transport infrastructure. Since 1996, the World Road Association (PIARC) undertook the responsibility of the management of this project further to the actions started by the World Bank. After the development of version 1.0, for which more than 1000 licenses were sold worldwide, PIARC led the development of version 2.0 taking into account remarks of the users. The HDM-4 version 2.0 was finalized in June 2005. In accordance with the resolution adopted by the PIARC Council, the management of the HDM-4 project has now been externalized. Following a call for proposals, a five year service concession contract was awarded to HDMGlobal, an international consortium of academic and consultancy companies led by the University of Birmingham. HDMGlobal has exclusive HDM-4 distribution rights, and is responsible for: (i) marketing, (ii) sale of licenses, (iii) assistance to the users, and (iv) management of further developments.


The HDM-4 Version 2.0 Software is now available for order from HDMGlobal. The HDM-4 Software package can be ordered from the official HDMGlobal distributor Ponts Formation Edition, which began processing orders on September 1, 2005. For more details, pricing, or to order please contact Ponts Formation Edition at the following email address: or contact Information regarding HDM-4 Version 2.0 can be found at the HDM Global Website.

The Expenditure Budgeting Model (EBM-32) is an enhanced version of the Expenditure Budgeting Model for the Highway Sector (EBM-HS) included in the 1995 release of the World Bank's Highway Design and Maintenance Standards Model (HDM-III). The EBM-32 model is an analytical tool for optimizing multiyear programs of expenditures under budgetary constraints and it is customized to analyze highways investments or maintenance projects (e.g., maintenance, construction, reconstruction projects) that are subject to two budgetary constraints: (a) capital expenditures and (b) recurrent expenditures. EBM-32 is particularly useful when used with the HDM-III and HDM-4 models, because it reads the network data generated by these programs.

The EBM-32 main enhancements in relation to EBM-HS are the capability to handle up to 400 projects, with each project having 17 project-alternatives, the capability to export the results to Excel, the inclusion of a front-end/back-end Excel workbook, and the possibility to link EBM-32 to Pavement Management System. EBM-32 is designed for use on 32 bit personal computers running Windows 95, 98 or NT.
