Welcome!
This website presents software tools and models developed by the World Bank to support monitoring, planning, programming and the economic evaluation of roads and highways works.
| ROAD SAFETY TOOLS: | |
| HDM-4 Road User Costs Model (HDM-4 RUC) Version 5.0 | |
| HDM4RUC Version 5.01 (ZIP file) | The HDM-4 Road User Costs Model (HDM-4 RUC) is an Excel based model designed to compute, for different vehicle types and road conditions, vehicle speeds, fuel consumption, vehicle operating costs, passenger time costs, emission and accident costs based on the Highway Development and Management Model (HDM-4) relationships. The model computes unit road user costs, performs sensitivity analysis, computes network road user costs and performs a simplified economic evaluation of a road project. The current version of HDM-4 RUC (Version 5.0) computes the vehicle operating costs and speeds, function of roughness, cubic polynomials that can be used together with the RED and RONET models. |
| Roads Economic Decision Model Version 4.0 | |
RED Version 4.0 English (ZIP file)
RED Version 3.2 English (ZIP file)
RED Version 3.2 Spanish (ZIP file)
| The Roads Economic Decision Model (RED) was developed under the Road Management Initiative (RMI), a key component of the 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 benefit 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 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 4.0), released in April 2018, which is available only in English, adds optionally CO2 emissions benefits or costs to the cost benefit analysis. RED version 3.2 is available in English, French and Spanish. With the same input data, both Version 3.2 and 4.0 produce the same results. |
| Road Network Evaluations Tools (RONET) | |
RONET Version 2.0 English (ZIP fie)
RONET Version 2.0 Spanish (ZIP file)
| The Road Network Evaluation Tools (RONET), developed under the Africa Transport Policy Program (SSATP) and the World Bank, is designed to assess the current characteristics of road networks and their future performance depending on different levels of interventions to the networks. RONET Version 2.00 implements three evaluation modules: (i) Current Condition Assessment Module that computes network statistics and monitoring indicators, (ii) Performance Assessment Module that estimates the network performance and budget requirements under different maintenance and rehabilitation standards, and (iii) Road User Revenues Module that evaluates revenues collected from road user charges and compares them with the funding requirements. RONET version 2.0 was released in January 2009 and is available in English, Spanish and Russian. |
| Road Costs Knowledge System (ROCKS) | |
| ROCKS Version 2.3 (ZIP file) | The Road Costs Knowledge System (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. The ROCKS database was last updated in 2008. |
| Highway Development and Management Tool Presentations and Case Studies | |
| HDM-4 Presentations and Cases Studies 1 of 5 (ZIP file) 2 of 5 (ZIP file) 3 of 5 (ZIP file) 4 of 5 (ZIP file) 5 of 5 (ZIP file) | The World Bank developed a series of tools to facilitate the dissemination and use of the Highway Development and Management Model (HDM-4) being distributed by HDMGlobal. The available tools are: (i) Collection of HDM-4 PowerPoint Presentations; and (ii) HDM-4 Version 2 World Bank Case Studies; and (iii) i) World Bank Transport Paper TP-20: Applying the HDM-4 Model to Strategic Planning of Road Works.Roads User Charges Model. |
| Roads User Charges Model | |
| RUC Version 3.0 (ZIP file) | The Road 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. Some of the functionality of the RUC model can be found on the RONET model. |
