Managing restricted traffic areas

Restricted traffic areas are network objects that allow you to model territories and link sequences with special constraints or restrictions (Fundamentals: Restricted traffic areas). These include driving bans, through traffic bans, or various concepts of tolls. Through traffic bans and driving bans can be considered in static assignments as well as simulation-based assignments (SBA).

Example

Proceed as follows if, for example, you want to define an environmental zone with driving bans for the Car transport system in a part of your network:

1.  In the desired part of the network, add a restricted traffic area of the type ‘No traffic’ ( Creating a restricted traffic area).

2.  In the Create/Edit restricted traffic area window, close the Car transport system for the defined area.

Note: Split the demand matrices as needed if the driving ban is not to apply to all vehicles in a transport system (e.g., only for a new transport system diesel cars).

All links that are completely within the restricted traffic area are automatically allocated to it. In assignments, all links belonging to the traffic area are closed for all traffic for the transport systems from the specified set.

Notes: If you do not want to include restricted traffic areas in procedures (Impact in procedures), impedances, shortest path searches, or graphical procedures, you can set them passive and select the Consider only active restricted traffic areas in impedance setting in the Calculate > General procedure settings > Impedance menu. On the same page, you can insert a detailed impedance definition for restricted traffic areas (Defining impedance functions for transport systems).
