SLIP'20 -- Update-info

Version 8.0e (2023)

Optimization: Calculations that involve many ground-type polygons with many vertices run faster.
Swiss10-DTV-converter: new coefficients for SS-50 (as published by EMPA+BAFU in [Swi10Knv23], Tab. 4.2).
Cleanup: a new parameter allows you to select closed polygons with a specified orientation.
QSI: import extended (for details, see documentation-topic QSI Import).
The short code displayed by the calculation-progress-bar (used algorithms and some of their most relevant parameters) has been extended; for details, see topic Selection-calculation.
Diverse improvements and optimizations.

Version 8.0d (2023)

All Swiss10-plus vehicles are now included (see new emission-input options for road-elements).
New day and night corrections for road-elements.
Ground-type extended: mixed grounds included.
Faster loading and saving of selections and projects.
Import: several extensions and improvements.
Diverse improvements and optimizations.
Program-documentation extended. In particular, note that, in the context of the model SonRoad18, a certain method/parameterization (incl. that of ISO-9613, which is used for the calculation of sound-propagation) may be "officially" preferred or even mandatory. Please check with the relevant authorities if a particular method/parameterization is prescribed for official calculation tasks. See also note and references in Topic SonRoad18.

Version 8.0c (2021)

Model SonRoad18:
- The CPX-interface (which uses models for 50 and 80 km/h acc. to [SRd18w21]) is now integrated in the emission-edition form (see field Pavement). This allows you to use a CPX measurement to specify the pavement (the inputted spectrum is automatically converted into a rolling-noise pav.-correction).
- It is now possible to directly input spectral rolling-noise pav.-corrections (see field Pavement in the emission-edition form).
The front-end is now 64-bit, which allows you to create considerably bigger projects. Also, most functionality should run ~10% faster.

Version 8.0b (2021)

Model SonRoad18:
- Recent "official" developments (acc. to [SRd18w21]) have been integrated:
  - New standard "KB-pavements" (standard pavement corr. spectra). For model SonRoad18, when modelling a "neutral" pavement, avoid using a model-reference pavement; instead, consider using a KB+0 pavement.
  - New version of the Swiss10-converter.
- The air-temperatures for the calculation of emissions is now configurable (the same settings are used for emision and propagation).
Elements can now have extended attributes (these can be freely defined by the user at the element-instance level).
Shape export extended: in particular, extended attributes can be exported.
Numerous other improvements.
