ANGIE – Agent-based Network Growth model with Incremental Evolution
The Agent-based Network Growth model with Incremental Evolution (ANGIE) models the growth of road networks in several scenarios such as road networks in an artificial grid-like city and the Minneapolis Downtown Skyway network.
More >
BRAESS– Braess Paradox Explorer
BRAESS demonstrates fixed-demand and elastic-demand user equilibrium on a small editable network.

General Attachment Lab – General Attachment Lab is a browser-based research and teaching module for access-based network growth.
It lets users simulate preferential attachment under capacity constraints, spatial cost deterrence, mesh framing, planarity handling, and accessibility-weighted growth, while preserving the true simulated coordinates of the evolving network.

CLUSTER – Clustered Locations of Urban Services, Transport, and Economic Resources
This model is an agent-based model of retail location choice on supply chains consisting of consumers, retailers, and suppliers.
More >
HSRDA -This model lets you build a corridor, test constraints, and compare defensible route options.
OASIS – Online Application for Signalized Intersection Simulation
The actuated signal control module was developed to help users better understand the control logic of an actuated signal controller.
More >
ROAD – Roadway Online Application for Design
This online roadway geometry design tool was developed to assist students conducting the geometric design of roadways on computer screen using a contour map in the background as reference.
