Change: Import of ERD files using formatted floating-point (text) has changed. When the FORMAT keyword is empty and data is not available for all channels for each record, the import will fail. Previously, the import would succeed but stop reading the file when missing data was encountered.
Analysis: Profiler Certification
Fix: Fixed regression that caused a validation warning when separate basis files were selected for the left and right channels.
Analysis: Smoothness Assurance
Fix: The fixed-interval chart sometimes displayed the wrong y-axis values when the chart height was small.

We’ll kick off the ProVAL Users Forum on March 19! The plan is to conduct it at a quarterly basis. This first one on 3/19 is an online, free and live ProVAL users forum (registration link: https://attendee.gotowebinar.com/register/3165214045740207196). The second one will be in-person as the second half of the 4-hr ProVAL workshop on 4/28 at the RPUG conference (registration link: https://forms.gle/SHXsjT76rLkeRVWF9). The 3/19 Forum is 2-hour interactive quarterly forums to engage with ProVAL user community to work together to keep ProVAL as the gold standard for pavement smoothness analysis. The topics are: 1) Selected ProVAL 4.x new features, functions, and tips, 2) Recent ProVAL 4.x bug fixes and their effects, 3) Users shared project files and issues (including bugs, questions, etc.), and 4) Users wish list for future ProVAL enhancements. Again, registration is free (https://attendee.gotowebinar.com/register/3165214045740207196). The attendees can send their ProVAL or pavement smoothness issues and example files to the trainers (info@RoadProfile.com) before the forum.
Change: Import of ERD files using formatted floating-point (text) has changed. When the FORMAT keyword is empty and data is not available for all channels for each record, the import will fail. Previously, the import would succeed but stop reading the file when missing data was encountered.
Analysis: Ride Quality
Fix: The KML/KMZ export for the Fixed-interval analysis only had the correct coordinates for the first selection.
Analysis: Rolling Straightedge
Change: Leave-outs are now removed from the analysis.
A 3-hr ProVAL Pavement Smoothness Workshop will be conducted on February 12, 2025 from 9AM to noon US CST. This is an online, live, hands-on-centric ProVAL pavement smoothness workshop. It includes two 80-minute sessions with a 20-minute break.
Session 1: Basic Topics (Fundamentals of Pavement Profiling, IRI Ride Quality Analysis, Profiler Certification),
Session 2: Advanced Topics (Power Spectral Density -PSD-, Smoothness Assurance Module -SAM- & Grinding Simulation, Other Modules, Case Studies)
Attendees will need to have two computer screens: one for viewing the instructions and one for running the ProVAL software. Download and install the latest ProVAL software and sample files (https://www.roadprofile.com/proval-software/current-version/). Certificates of completion with 3 PDH or 0.3 CEU units will be emailed to participants. US FHWA and DOT personnel can register with their agency’s official emails and apply a discount code of “agency” (in lowercase). Click here or the image below to register and reserve your seats!
This year’s events will include online and in person workshops and *** New *** ProVAL users forum.
Online ProVAL on-demand workshops: Three hours hands-on-centric workshop. Focus on the essential ProVAL features for smoothness assurance and ride quality analysis. Discuss real-world case studies to identify common roughness issues to improve smoothness.
Free Quarterly Live ProVAL User forums: Two hours of interactive online forums to discuss. Selected ProVAL 4.x new features, functions, and tips, Recent ProVAL 4.x bug fixes and their effects, Users shared project files and issues (including bugs, questions, etc.), Users wish list for future ProVAL enhancements.
Fix: PSG results were incorrect when the option for “Use SI Units” was changed from checked to unchecked.
Analysis: Ride Quality
Change: The Fixed-interval analysis was changed to better match the results of ProVAL 3.6. Differences may still occur due to ProVAL 4’s improved accuracy with regards to distance.
Fix: When using SI units, non-RN overall ride quality values were displayed in m/m instead of m/km.
Reports
Change: Reports sometimes cannot be created because the profile or section names contain text that is not allowed by Windows. ProVAL will now attempt to remove problem text. When this happens, a timecode will be appended to the file name to ensure the file name is unique.
Improved feedback of problems that prevent saving a report file.
Miscellaneous
Fix: Project files were sometimes saved with the wrong permissions, causing the files to not be openable on other computers.
Fix: Adding files to a project would take progressively longer each time during a session.
Fix: Changes to joints did not mark the project file as unsaved.
Analysis: Profile Screener
Fix: The extreme and low roughness analyses were incorrect.
Fix: False-positives were sometimes reported for the low-pass filtering detection.
Analysis: Profilograph
Fix: The blanking bands were not always drawn correctly (or crashed) when multiple files were analyzed.
Analysis: Ride Quality
Fix: Fixed interal for HRI and IRI was showing HRI for the value of the right IRI.
Fix: Fixed interal for MRI and IRI was showing MRI for the value of the right IRI.
Fix: The fixed interval chart could not be copied, saved, or printed.
Analysis: Smoothness Assurance
Fix: Rolling straightedge comparison did not work.
Miscellaneous
Using the profile selection buttons in the toolbar (left, center, right, all) will no longer apply the analysis filter template if a profile was already selected.
Fix: When applicable, Sections were missing coordinates when imported from PPF files and previous ProVAL projects. For any projects saved with 4.0, the routes will need to be re-applied for coordinates to be assigned to Sections.
Fix: The File Import Wizard did not work well for very short profiles.
Editor
Fix: Exporting a section that could not be saved due to invalid text in the resulting file name caused a crash. A warning will now be shown.
Analysis: Ride Quality
Change: Previously, the analysis would stop if any errors occurred. Now, the analysis will attempt to always analyze all profiles.
Fix: Changing the input values might not clear the results and enable the Analyze button.
Miscellaneous
Fix: Project file paths containing non-ANSI characters may not be able to opened or saved.
Fix: ProVAL did not always close after an error occurred.
Performance improvements.
Stability improvements.
