  2. sources(roads) buildings terrain Digital Town Model Generation of a Digital Town Model

  3. Input Data - Road Network total road length: 280 km distribution of traffic AADT: roads coast line municipal border

  4. Distribution of Traffic Load road sections coloured based on their AADT-data legend: coast line municipal border

  5. Input Data - Buildings total number of buildings within San Juan municipal border: 111562 building height in classes: buildings coast line municipal border

  6. Distribution of Building Heights legend: coast line municipal border

  7. Distribution of Building Heights- San Juan town centre - legend: coast line municipal border

  8. Input Data - Terrain Model modifications due: - absolute heights corrected - arbitrary splines deleted - coast line at h=0 m was missing: coast line modelled from contour line at 1 m height by a parallel line at 5 m distance

  9. San Juan - Digital Town Model total town area: 128 km²

  12. Calculation Standards/Guidelines • Road Noise: German Guideline RLS-90, edition 1990 • RLS-90 calculates: • 1st reflection order • two outermost tracks separately • no lateral diffraction • no attenuation due to foliage

  13. CadnaA - Configurations of Calculation • 1st reflection order • grid interpolation 9*9 • max. search radius for sources: 2500 m • no projection of line & area sources • ground absorption included (porous ground) • evaluation parameters: Lday (6 am - 10 pm) Lnight (10 pm - 6 am)
