We’re excited to announce that our TrafxSAFE family of products (TrafxFLOW, TrafxSAFE Connect, and TrafxSAFE Rail) has been updated to provide enhanced performance and value for for you. Among the many new feature additions, this release includes one of the most requested from our users — interactive heat maps! Check out the new updated features in detail below:

Support for Interactive Figures

Heatmaps of all kinds can now be interacted with to display trails and clusters specific to individual scenarios, movements, or road user types and include the following:
  • Support for interactive figures for the conflict heatmaps, the speed heatmaps, and two new density figures (See below for more details).
  • The ability save your customized  interactive figures for each site and can be printed in the report.pdf
  • We’ve made it more obvious which figures are generated for which time period or camera, and they are easier to select.
  • Both aerial and camera views have now been converted into 2 different varieties of the same figure type (which means only one is shown or printed at a time). Which variety of figure is now displayed or printed is a user configuration. This applies to all figures that display spatial information and this change is backwards compatible with older data.

Generating interactive figures is supported starting with our analysis engine version 0.7 or higher only. This means that older projects will not be automatically updated to use the new interactive figures. However, we will continue to support these figures for older projects in the same way.

Conflict Density Heatmap

The new Conflict Density Heatmap will show locations with the highest frequency of interactions below the desired design reaction time. While the existing Conflict Heatmap (ASIV) is ideally suited to evaluate problematic areas based on the safety effect, it may be less suitable for triaging movements based on the number of road users affected. This is where the Conflict Density Heatmap is most useful.


Trajectory Presence Density Heatmap

The solution to oversaturation of Trajectory line plots when performing a visual inspection of swept paths, trajectory clustering, and desired paths. With this figure, you can identify which paths clusters of road users take to perform any particular movement or scenario. Unlike Trajectory line plots, they are built from the population of data, not just a sample.


Data Collection Point

Data collection point data is now automatically included in the raw data download feature. As a reminder, data collection points allow for the collection of arrival time, dwell time, and instantaneous speed at specific locations, as if an induction loop was installed at that location.



Other Updates and Improvements

  • Support for 360° cameras
  • Charts, figures, and summary statistics generated using a context more specific than “site wide” now have appropriate titles to make it easier to identify when exported in printed reports and elsewhere.
  • Replaced the old report.pdf renderer with the same one used in the browser to simplify testing and maintenance.
  • A number of performance improvements to ensure more platform scalability, reliability, and speed.

Transoft Solutions remains committed to providing our users with the most up-to-date software with expanded features and fixes so that they will always be up to any challenges of their work. If you have any questions about the new updates, please contact us at
