Citilabs is pleased to announce the release of Cube 5.1

Cube 5.1 introduces new features in:

• Cube Base
• Cube Voyager
• Cube Avenue
• Cube Land

In addition, Citilabs has updated its demonstration models. Of particular note are three new applications:

• Activity-Based Model
• Land Use-Transport Interaction Model
• Land Use Model

The Activity-Based Model is a complete application covering the typical aspects of this approach. Please feel free to take this application and build your own Activity-Based Model in Cube. Note that the parameters within this setup are generic. You should estimate local model parameters using your own data.

The Land Use-Transport and Land Use Models highlight the integration of Cube Land within the Cube suite of modeling tools.

These applications are contained within a new Cubetown model application catalog available for download at: http://www.citilabs.com/tutorials.html
