The current version of RED Version 4. RED version 3. With the same input data, both Version 3. RONET version 2. Roads User Charges Model. 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.
Related HDMGlobal. 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. RED version 3. With the same input data, both Version 3. 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.
RONET is a model which could be used by decision makers to appreciate the current state of the road network, its relative importance to the economy e. With RONET the performance of the road network is assessed over time under different road maintenance standards. It determines, for example, the minimum cost for sustaining the network in its current condition and estimates the savings or the cost to the economy for maintaining the network at different levels of services.
RONET determines the allocation of expenditures among recurrent maintenance, periodic maintenance, and rehabilitation road works, determines the optimal maintenance standard for each road class highest Net Present Value and compares it with the current budget constraint and other maintenance standards.
Finally, it determines the "funding gap" defined as the difference between current maintenance spending and required maintenance spending to maintain the network at a given level of service and the effect of under spending on increased transport costs. The Road User Revenues Module estimates the level of road user charges required e.
This could be used by road fund boards to prepare a business case to negociate and revise road tariffs on a sound basis. Windows application for predicting the strength of a pavement for analysis with HDM-4 using different techniques. Unfortunately, it can be rather expensive for a full version, and version upgrades are at full price. R is a free, open-source programming language that is commonly used to conduct statistical analyses.
It supports a diverse range of packages and processes, such as geospatial calculation, machine learning tools, and advanced graphics. However, its versatility is dependent on that code syntax and function structure, compared to other software that operates more like a record of actions in relatively more "plain-English" command styles.
