List of Traffic Sources

Form for Traffic Sources

Definition of traffic sources for the propagation calculation.

L-NR

Index Number, where L identifies traffic / line sources.

Descriptor

Unique descriptor for a data set.

Obstacle

The source coordinates can be referred to one of the obstacles (building), though they can be moved with each other.

Street source

If checked, then it is a street source else it is a railway source.

X1, Y1, Z1, X2, Y2 and Z2

Location of the source in a 3-dimensional space. Begin and Endpoint are identified by three coordinates.

Level

If a value is entered instead of a reference to a spectrum, it will replace all entries of the spectrum (in case of A-weighted calculations, it will also replace the column for the weighted levels).

Dr2

Drefl and Dr2 are supplements for multiple reflection defined in the guidelines RLS-90 and SCHALL 03. This value is to be entered into the list of traffic sources manually. Both guidelines suggest for a gorge a value of 4*h/w with the gorge depth h and the width w.
