What’s New in ADMS-Roads 4.0?
November 2015
ADMS-Roads 4.0 is the latest general release of CERC’s state of the art model for the
dispersion of pollutants in urban areas. ADMS-Roads 4.0 contains a number of major new
features and model options, most notably:







an advanced street canyon modelling option, which modifies the dispersion of
pollutants from a road according to the presence and properties of canyon walls on
one or both sides of the road allowing for pavements within canyons and the transport
of pollutants from one canyon to an adjoining canyon;
a tunnel modelling option, which modifies the dispersion of pollutants from a road
source to take into account dispersion from the tunnel portal(s) and any vent(s);
a new import option allowing source, group, and pollutant data to be imported directly
into the ADMS-Roads interface. Alongside this an export option allows for
information to be easily transferred between model set-ups;
several additional features in the ADMS Mapper, extending the ability to visualise
model input and output. These enhancements include the ability to plot flow field
output from the Urban Canopy module, display a north arrow, and transfer the look of
one contour plot to another;
additional functionality in the ADMS-Roads interface to allow for easier manipulation
of group membership, outputs, and sources using right-click menus;
road emission factors from the UK DRMB Interim Advice Note 185/15;
the ability to run up to 10 years of sequential meteorological data in a single model
run.
This document contains details of the new features, scientific improvements and model
corrections implemented since the previous version of ADMS-Roads (version 3.4, January
2015). Also contained in this document are instructions for installing ADMS-Roads 4.0 and
upgrading from previous model versions.
IMPORTANT NOTE FOR THE UPGRADE OF MODEL RUNS
Any additional input files (.uai) need to be upgraded before they can be used with ADMSRoads 4.0. Full details of how to upgrade these files is given in this document.

Upgrading your input files
Additional input (.uai) files
Any additional input (.uai) files must also be updated so that they are in file version 5 format.
To do this:
1. In Explorer, make a backup copy of the file.
2. If the Spatial truncation option is being used this must be turned off before the file can
be upgraded. To remove this option manually open the .uai file in a text editor and
delete the section entitled SPATIALTRUNCATION.
3. Open the .uai file in the Additional Input file editor, which can be opened from the Edit
button on the Setup screen of the ADMS-Roads interface.
4. Click Yes to allow the editor to upgrade the file.
5. Re-add the Spatial truncation settings if this option is required.
6. Save the file.
7. Reference the new .uai file in the Setup screen of the ADMS-Roads interface.
ADMS-Roads 4.0 has an Additional Input file editor, which can be used to create and edit .uai
files. The editor can open .uai files in file version 3 or 4 format provided the Spatial truncation
option is turned off as described above, but will always save files as file version 5. .uai files
must be file version 5 for use with ADMS-Roads 4.0.

New Features and Major changes
ADMS Mapper
1. For all types of output grid the ADMS Mapper now displays the output points
associated with this grid. This is in addition to the existing display of the extent for a
regular Cartesian grid. Refer to Section 2.8 of the ADMS Mapper User Guide for
more details.
2. A new option to load Web Map Services in the ADMS Mapper has been added. For
details on this option refer to Section 5.3 of the ADMS Mapper User Guide.
3. Right-click menus have been added to the legend in the ADMS Mapper. These menus
provide a convenient way of exporting the layer data as well as providing options to
save and load configuration files controlling the visualisations of each layer. The
ability to save and load configuration files allows for the look of one contour plot to
be transferred to another. Refer to Section 4.8 for more details.
4. An individual source or specified output point can be highlighted in the ADMSMapper from a right-click menu on the source or output screen respectively.
5. When importing a comma-separated file into the ADMS Mapper a wizard appears to
select the data and enter appropriate headers. Refer to Section 5.4.2 for more details.
6. A north arrow is now displayed in the ADMS Mapper. Refer to Section 5.7 for more
details.
Utilities
7. The Import sources from CSV file utility has been updated to allow data to be
imported directly into the ADMS-Roads interface and therefore into an existing .upl
file. This option now allows sources, group data, and pollutants to be imported. To
facilitate these new features the format for the CSV files used for import have
changed. It is also now possible to export data from the ADMS-Roads interface in the
same format. Refer to Section 5 of the ADMS-Roads User Guide for more details.
8. A new facility is provided to automatically create an .asp file containing output points
which describe a vertical slice. The user draws a line in the ADMS Mapper to
determine the position of the vertical slice. Refer to Section 7.4 of the ADMS-Roads
User Guide for more details.
9. The Contour plotter has been replaced with a new 2-D output plotter. There have
been several enhancements to the functionality for this new utility:
a. It is now possible to plot specified point data directly from the utility,
providing there are sufficient data points.
b. The flow and turbulence fields output from the Urban Canopy module can be
plotted in the ADMS Mapper or in Surfer. Refer to Section 6.2 of the ADMSRoads User Guide and Section 3.2 of the ADMS Mapper User Guide for more
details.

Road source modelling
10. A new advanced street canyon modelling option for road sources is available. This
option modifies the dispersion of pollutants from a road according to the presence and
properties of canyon walls on one or both sides of the road allowing for pavements
within canyons and the transport of pollutants from one canyon to an adjoining
canyon. For more details refer to Section 4.2 of the ADMS-Roads User Guide.
11. A new road tunnel modelling option for road sources is available. This option
modifies the dispersion of pollutants from a road source to take into account
dispersion from the tunnel portal(s) and any associated vents. For more details refer
to Section 4.4 of the ADMS-Roads User Guide.
12. The UK DMRB IAN 185/15 emission factors for road sources have been added to the
ADMS-Roads emission factors database. These are taken from the DMRB Interim
Advice Note 185/15. For more details refer to Section 3.2.1 of the ADMS-Roads User
Guide.
Groups
13. Several changes have been made to the Groups screen of the ADMS-Roads interface:
a. It is now possible to copy and rename groups.
b. A new option to automatically create a group for each industrial source has
been added.
c. A new right-click menu on the Groups screen that allows for manipulation of
the included sources within a group, including automatically adding all
sources of the same type.
d. A new right-click menu on the Source screen that allows for sources to be
added and removed from existing groups.
Output
14. The ADMS-Roads .log file has been supplement by two additional reporting files
containing errors (.err) and warnings (.wng). The messages in these files are identical
to those in the .log file, but these files provide a convenient way of easily obtaining
any errors or warnings. If no errors or warnings were issued by the model then these
files will not be created.
General
15. There have been several enhancements to the spatial truncation option:
a. The maximum allowed size of the buffer region has been increased from
500 m to 5000 m.
b. Spatial truncation can now be applied separately to point, line, area and
volume rather than only to all industrial sources.
16. Up to 10 years of sequential meteorological data may now be modelled in a single
model run.

17. Right–click menus have been added to various screens in the ADMS-Roads interface
to allow for additional functionality in selecting included groups, outputs and sources
and for the duplicating of sources.
18. Pollutant emissions can now be added or deleted from all sources of that type (e.g.
road source) on the emissions screen. This is particularly useful for road sources
when changing between traffic emission data sets which contain different pollutants.
Note that for other source types, and road sources without calculated emissions, an
emission rate of 0 is added for that pollutant.

Minor Changes
Chemistry
19. An issue has been fixed whereby previously incorrect long-term statistics may have
been calculated when chemistry was being modelled and the meteorological file
contained lines for data which were valid for dispersion but not for chemistry
calculations.
General
20. Improvements have been made to simplify the pasting of individual values copied
from Excel into ADMS-Roads.
21. The file size of .upl files has been reduced when there are large numbers of sources.
22. A new kriging interpolation method is available in the Grid Interpolator. This new
interpolation method is able to interpolate files with large output grids.
23. It is no longer possible to carry out contour plots in the ADMS Mapper using ArcGIS
Spatial Analyst; the inbuilt grid interpolator can be used instead.
24. When the spatial truncation option is used with a buffer region any sources partly in
the buffer region are now included in the model run, previously sources had to either
be partly in the modelling region or wholly in the buffer region.
Emission inventories
25. The number of sources which can be imported from an emission inventory has been
increased.
26. The ability to delete pollutants or sources from an emission inventory has been
removed.
