Adjustment of the Configuration

Starting from the CadnaA release 4.6.153 the previous configuration options

  • „Special Reference Time for Industry (min)“ on the „Reference Time“ tab) and
  • „Compatibility Mode for Industry“ on the „Evaluation Parameters“

are no longer available.

These changes are caused by the implementation of diurnal patterns for industrial sources (see Common Input Data, Addressing Diurnal Patterns and chapter Diurnal Patterns).

When loading files saved with previous releases of CadnaA an automatic adjustment of the configuration settings occurs in order to ensure that - even after dropping these options - the same calculation results are obtained.

Examples

Below some examples for typical configuration adjustments are explained:

  • case 1: file with industrial sources only and the compatibility mode activated
Message Remarks
The option "Compatibility mode for Industry" is disabled and the evaluation parameters are changed to: Ld --> Lde The evaluation parameter can be changed directly from Ld to Lde.
The "Special Reference Time for Industry (min)" with Day: 780.00 min, Evening: 180.00 min, Night: 60.00 min will be transferred to the Allocation Hour - Periods (on "Ref.Time" tab) by: 13 h D, 3 h E, 1 h N The transfer of the special reference time for industry to the allocation Hours-Periods is directly possible.
  • case 2: file with industrial sources only and the compatibility mode NOT activated
Message Remarks
no message regarding "Compatibility mode for Industry" displayed as not used (e.g. with eval. parameters 1: Lde, 2: Ln set) -
The "Special Reference Time for Industry (min)" with
Day: 780.00 min, Evening: 180.00 min, Night: 60.00 min
will be transferred to the Allocation Hour - Periods (on "Ref.Time" tab) by: 13 h D, 3 h E, 1 h N
see case 1
  • case 3: file with industrial and other source types and the compatibility mode activated, while the option „Use Non-Standard Reference Time D/E/N“ (for railway and/or aircraft noise) is activated
Message Remarks
The option "Compatibility mode for Industry" is disabled and the evaluation parameters are changed to:
1: Ld --> (indde++strd++ schd++spod++flgd)
The new evaluation parameter 1 is represented by the energetic summation of all source types (with Lde for industry (indde, Day/Evening mixed level) and sports tennis source Day (spod).
This representation is required as esp. for roads and railways the Ld was calculated as daytime level, while for industrial sources, however, the Lde was calculated.
The "Special Reference Time for Industry (min)" with Day: 780.00 min, Evening: 180.00 min, Night: 60.00 min
will be transferred to the Allocation Hour - Periods (on "Ref.Time" tab) by: 13 h D, 3 h E, 8 h N
WARNING: Special Reference Time is not compatible with "normal" reference time!
A warning message is displayed, as for rail or aircraft noise the option "Use Non-Standard Reference Time D/E/N" was activated. This causes that the entered special reference times for industry can not be modified in a compatible way without altering the settings for railway during nighttime.
NOTE - This incompatibility, however, existed in the old file already and, therefore, the problem is not due to the modification of the configuration.
  • case 4: file with industrial and other source types and the compatibility mode activated, while the option „Use Non-Standard Reference Time D/E/N“ (for railway and/or aircraft noise) is NOT activated
Message Remarks
The option "Compatibility mode for Industry" is disabled and the evaluation parameters are changed to:
1: Ld --> (indde++strd++schd++spod++flgd)
see case 3
The "Special Reference Time for Industry (min)" with
Day: 780.00 min, Evening: 180.00 min, Night: 60.00 min
will be transferred to the Allocation Hour - Periods (on "Ref.Time" tab) by: 13 h D, 3 h E, 1h N
No warning is displayed because the option "Use Non-Standard Reference Time D/E/N" was not activated. This means that the allocation of hours is not relevant for source types Railroad and Aircraft. It is used: D: 16 h, N: 8 h.
