Simulations

Many simulations can be found at the Simulating Transportation for Realistic Engineering Education and Training (STREET) project. These simulations are interactive models that require java be installed on your machine.

The following simulations are available for download, but are too large to run interactively. They were used in the research associated with Xie and Levinson (2011) Evolving Transportation Networks.

• SONG 2 – System of Network Growth. [doi]
• SOUND – System for Ultraconnected Network Degeneration (with code to analyze network geometrics).[doi]
• SIGNAL – System of Integrated Growth of Networks and Land Use. [doi]
• SONIC – System of Network Incremental Connections.[doi]

Software repository

• Many open source programs can be downloaded from the Nexus / Accessibility Observatory archive at GitHub.
• Code for Primal and Dual Accessibility from Mengying Cui’s GitHub.

Data

• Model Accuracy Data for Post-Construction Evaluation of Forecast Accuracy in Minnesota
• Minneapolis Safety In Numbers Investigation Data

Networks

The following test networks have been developed by the Nexus Group.

• Indiana Interurban Network and land data in spreadsheet [doi]

• The networks used in Table 5 of Xie and Levinson (2007) Measuring the Structure of Road Networks. [doi]
