Modelling Area Tolls
• Most modellers use link-tolls on entry links
• (A) Start in the area → trivial for routing, matrix calculation for input to demand modelling
• (B) Enter the area once → ok
• (C) Simple through trips → ok
• (D) Multiple entries → multiple charges for route choice, complexity for matrix calculation for demand modelling
• Average VOTs →all-or-nothing toll choices
• Income segmentation
Restricted Traffic Areas with PTV Visum
• Area toll (pay once) type
• Works with static assignments (including ICA) and dynamic assignment with SBA
• Can be combined with TRIBUT to model continuous VOT
• Calculations of skims, the calculations of volumes from flow bundles and OD pair filters,
• Calculation of toll revenues
A. Start in area
B. Enter area once
C. Simple through trips
D. Multiple entries
