Last change on this file since 11336 was 8520, checked in by spimming, 12 years ago

#1894:

  • extended datasource interface to get routing graph for a specific vehicle type
  • use ICostCalculator to calculate edge weights
  • moved common enums in own file
  • removed method to estimate cost from graph; use ICostCalculator
