Density of transport network (existence of replacement routes)

 



  • Indicator

[log of km of rail and road network/ hectares tourism region]

  • Range
 [-]
  • Influence on vulnerability
 The more the transport network is dense, the more substitute accesses exist in the case of natural hazards.
  • Trend
 Logarithmic ↓
  • Data source
 Data calculates using information on the street and rail networks presented in VECTOR25 (SwissTopo 2007).
  • Remarks

This indicator is approximate. For a valley, a second road placed on the opposite slope could already grant accessibility. Moreover, no distinction is made between 1-line- and bigger roads.
