ArcGIS has seen a widespread application in transportation planning and research. I have considerable experience of using ArcGIS not only in data extracting and mapping, but also in creating animations to display the evolution of networks. The following movies are created by me (some with my colleagues) for various networks. The Indiana Interurban movie can be downloaded from this site. Other movies are available on the NEXUS website. Some are large files, so may take a while to download. To play these movies requires that quicktime be installed on your machine.
This page contains simulations and movies that I have developed in my research using Java and ArcGIS.

Java is the primary computer tool I have been employing to construct models and display simulation results. I have developed a series of java applets and applications not only for research purpose, some of them also developed into curriculum tools.
System of Ultraconnected Network Degeneration (SOUND) (with codes to analyze network geometric) (code) is a java applet that simulates network growth in a process of network degeneration (Xie and Levinson, 2006). Xie and Levinson (2007) analyzed the geometry of emergent network structures in this model.
System of Integrated Growth of Network and Land-use (SIGNAL) is a java applet that simulates the co-evolution of transportation and land use (Levinson, Xie and Zhu 2007).

System of Network Incremental Connections (SONIC) is a java applet I developed to simulate network deployment in a sequential process.  With alternative pricing and investment policies incorporated, SONIC was used by Xie and Levinson (2007) to compare network deployment under centralized versus decentralized jurisdictional control. The movies below display how a given set of places (represented by dots) was connected incrementally by roads (different capacities in different colors) under alternative control.

System of Network Growth (SONG 1.0) (web access; instructions) is a java applet I developed based on Levinson and Yerra (2006) to demonstrate how a transportation network evolves into a hierarchical system in a spontaneous process. The applet was used as an education tool for CE 5214 “Transportation System Analysis” in 2004 Spring.
System of Network Growth (SONG 2.0) (code; readme file) is a java application I wrote with the help of Norah Montes de Oca and Shanjiang Zhu. Enclosing a series of regional planning models for the Twin Cities Metropolitan Area, it was primarily used for Beyond Business as Usual project to forecast the Twin Cities road network twenty years from now.

SAND 1.0
Simulator and Analyst of Network Design (SAND) (web access; instructions) is a java applet that visualizes changes to a network and resultant traffic patterns, and allows users to evaluate the impact of these changes. In response to the tragic collapse of the I-35W bridge in Minneapolis, students of CE 5212/PA 5232 in Fall 2007 were asked to accommodate the congestion incurred on a road network across a river while missing a bridge link using SAND.
