TU06 - New V/D-functions for urban environments - revision of the TU71-functions (English)
Abstract [sv]

Static equilibrium models play an important role in long-term traffic planning. A central assumption in this kind of models is the underlying volume delay functions, commonly called V/D-functions. For applications in Stockholm and Gothenburg, the so-called TU71-functions are used for traffic assignment on one hour basis. These functions are derived from a rigorous traffic investigation in early 1970s. However, the functions partly fail to describe the current traffic situation. The TU71-functions are in this report examined and adjusted, resulting in a new set of functions (TU06). The TU06-functions include functions for two additional road types: freeways with speed limit 70 km/h and 90 km/h. Three of the original functions have been adjusted. The TU06-functions have been evaluated by Emme/2 runs on the Stockholm network. It shows that the new functions result in an improvement in the comparison between model results and traffic measurements. The new functions have so far only been evaluated for the Stockholm network. Further comparisons and tests in other cities are needed in order to assure general validity. Moreover, the TU06 functions affect the travel times to such an extent that new runs of the SAMPERS model must be considered.
