Road Costs Knowledge System

Application          Version Date Size Description
ROCKS
(ZIP file)
2.01 9/02 2,670 Kb The Road Costs Knowledge Systems (ROCKS)provides an international knowledge system on road work unit cost for road preservation and development activities. It is an institutional memory (database) that collects historical data on road work costs per kilometer or per M² that could ultimately improve the reliability of new cost estimates and mitigate the risk generated by cost overruns.

Highway Development and Management Tool and
Highway Design and Maintenance Standards Model

Application          Version Date Size Description
HDM-4 . . . The Highway Development and Management Model (HDM-4) version 1.3 was released January 2002. For more information about HDM-4, visit the HDM-4 Information Center managed by PIARC (the organization responsible for coordinating the availability, support and training opportunities for HDM-4 users, and future research and development activities), the HDM-4 Model home page maintained by the World Bank, and the ISOHDM home page maintained by the HDM-4 Secretariat.

HDM-III (1995)
(ZIP file)
3.0 1995 1,299 Kb The Highway Design and Maintenance Standards Model (HDM-III) is a computer program for analyzing the total transport costs of alternative road improvement and maintenance strategies through life-cycle economic evaluation. The program provides detailed modeling of pavement deterioration and maintenance effects, and calculates the annual costs of road construction, maintenance, vehicle operation, and travel time needed to perform the economic evaluation of the alternatives being considered. The 1995 HDM-III system was replaced in March 2000 by the HDM-4 model which is the recommended software for evaluating highway investment options. The 1995 HDM-III system is available for downloading at this site, together with the HDM Manager documentation and the HDM-III Volume 1 documentation (13.2 MB) (The Highway Design and Maintenance Model: Description of the HDM-III Model, by Thawat Watanatada and others).
HDM-VOC
(ZIP file)
4.0 11/93 109 Kb The Vehicle Operating Costs Model (HDM-VOC) is a stand alone program that estimates vehicle operating costs, using the HDM-III relationships, for ten vehicle types as a function of the vehicle characteristics, vehicle utilization, vehicle unit costs, and the road characteristics. The HDM-VOC software is available for downloading at this site, together with Technical Paper 234 "Estimating Vehicle Operating Costs" by Rodrigo S. Archondo-Callao and Asif Faiz..
HDM-PRD
(ZIP file)
1.2 4/96 560 Kb The Paved Roads Deterioration Model (HDM-PRD) is a stand alone program that estimates the road deterioration of paved roads, using the HDM-III relationships, as a function of the road characteristics, traffic, loading, and maintenance operations. The program is suited for road deterioration prediction, remaining life prediction, sensitivity analysis, road design analysis, road network deterioration, and road deterioration calibration.
EBM-32
(ZIP file)
1.0 2/99 319
Kb

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.



Roads User Charges Model

Application          Version Date Size Description
RUC
(ZIP file)
3.0 4/99 442 Kb The Roads User Charges Model (RUC) estimates road user charges required to ensure that, for a particular country, the costs of operating and maintaining all roads are fully-funded, and that each vehicle class covers its variable costs. The model is an Excel workbook that: (i) estimates annualized maintenance costs needed to maintain a stable road network; (ii) defines countrywide annual recurrent expenditures, annual investments needs, and source of financing; (iii) estimates road user revenues from annual license fees, fuel levies, load damage fees, and tolls; (iv) analyzes the allocation of road user revenues and optimizes road user charges; and (v) computes externalities and summary macro indicators.

Roads Economic Decision Model

Application          Version Date Size Description

Roads Economic Decision Model (RED)
3.2 06/04 2,689 Kb The 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."
DETOUR
(ZIP file)
1.0 9/99 73 Kb The Deterioration of Unpaved Roads Model (DETOUR) implements in MS-Excel the road deterioration relationships for unpaved roads of the Highway Design and Maintenance Standards Model (HDM-III), which are the same as the forthcoming Highway Development and Management Model (HDM-4). DETOUR was developed for the World Bank Rural Transport Thematic Group and is designed primarily for engineered unpaved roads, of either gravel or earth surfacing, because the empirical models are based on a variety of such roads. When necessary it is possible to use the relationships also for tracks as a first estimate, but the user needs to be aware that the environmental effects of drainage and rainfall may be poorly represented. For more information regarding roughness and the economic aspects of low volume roads, visit the Design & Appraisal of Rural Transport Infrastructure Web page maintained by the World Bank Rural Transport Thematic Group.
