HDM-4 Version 2.09 Upgrade
HDM-4 Version 2.09 Upgrade is now available free to registered HDM-4 Version 2 licence holders by downloading from the HDMGlobal website. This upgrade introduces the possibility for users to use the proposed incremental model for concrete pavements and offer feedback on the results obtained before they are finalised, as well as a number of other issues identified in HDM-4 Version 2 identified below.
1) CONCRETE RD & WE: The absolute concrete RD models did not always give reliable results unless the pavement was modelled from its construction year. This has been addressed by introducing Incremental Concrete Road Deterioration Models that better support the modelling of concrete pavements at any point within their lifecycle. These models are introduced in this version of the software to enable users the opportunity to provide feedback on the proposed new models and therefore they may be updated following this process. The user can switch to use the previous absolute models in the HDM-4 Options tool. The Concrete Work Effects triggering and effects have been improved to support the incremental models and ensure work items trigger as expected.
2) ROAD NETWORK: When creating a bituminous section from aggregate attributes, the correct pavement thicknesses were not always selected for the derived SNP. This error has been corrected.
3) WORK EFFECTS: In some circumstances it was possible that an incorrect limitwas applied to patching works when the user defined a maximum material quantity to be used. This issue has now been resolved.
4) WORK EFFECTS: If a user defined several intervention criteria which contained different maximum quantities, the quantity from the correct ORgroup was not always applied. This has now been resolved.
5) IMPROVEMENT STANDARD: The limit for the Rise and Fall of a section after an improvement was much lower than the limit defined within the road network data entry dialogs. This has been corrected to ensure consistency.
6) ROAD USER EFFECTS: The Annual Average Indicators were not always calculated correctly if the section was assigned a Traffic Flow Pattern with greater than one flow period. This error would only affect the annual average figures reported and the economic analysis results would have been unaffected. The error in the computation of the annual average RUE figures has now been corrected
7) ROAD NETWORK: For an unsealed pavement type the surface material selected in the calibration item is not displayed correctly. This has been fixed. 8) CALIBRATION SETS: When defining an unsealed calibration items and selecting a new surface material the user is prompted to use the default material properties for the surface material. These default properties are entered into the calibration item but are not saved when the user exits the dialog. This error has been corrected.
9) IMPROVEMENT STDS: For lane addition operations the final carriageway width limits were being incorrectly reported and used in the validation. The reporting and check have been corrected.
10) DATA MIGRATION TOOL: In some circumstances the Data Migration Tool would report that the HDM-4 Version 2 application could not be found, and then proceed to open the application. This error has been resolved.
11) WORKSPACE: In some instances, if a user tried to create a new workspace without another one open an error would be reported with an error code of -2004. This error has now been resolved.
12) PROGRAMME ANALYSIS: When performing an analysis using 'Multi-Year Forward Programming' any recurrent work costs incurred in the "delay works" option during the year in which capital work is performed on the "Work Programming" option were not included in the economic analysis. This error has been resolved.
