AIMSUN Planner

AIMSUN Planner is a Demand Analysis Component that has two main objectives:

To support all the operations necessary for the calculations with the Origin to Destination matrices as required by the analysis of the demand in transport planning
To provide a computational platform for the manipulation of the Origin to Destination matrices to generate the inputs to the microscopic simulation.

To achieve these objectives it contains the functions to:

Edit O/D matrices
Manipulate O/D matrices: join, split, balance
Matrix balancing based on a Furness model
Matrix adjustment based on link flow counts based on a Bi-level Gradient Heuristic
Automatic Generation of Local Traversal OD matrices for sub-networks
Detailed analysis of the results of transport planning operations

Traversal Matrices

Interactive generation of a traversal matrix (cordoning) is easy. The user selects with the mouse the sub-network of interest, and then selects the global O/D matrix whose traversal has to be estimated. The Traversal Calculation will automatically complete the task.

Planner Approach

This Component consists of an ad hoc version of a Static User Equilibrium model, the corresponding Frank-Wolfe algorithm for transport planning analysis, and all the associated visualisation functions.

The static user equilibrium traffic assignment is based, as is usual in these types of models, on Wardrop's principle.

3D Views

The astonishing 3D views are great for presentations. In the 3D view, all the different elements related to transport are present (cars, lorries, buses, trams, pedestrians) as well as the surrounding elements to a transport network (buildings, trees, etc.).

3D views have the great quality of offering different angles and points of view of the network.
