Welcome to the UrbanSim Project

UrbanSim is a software-based simulation system for supporting planning and analysis of urban development, incorporating the interactions between land use, transportation, the economy, and the environment. It is intended for use by Metropolitan Planning Organizations (MPOs), cities, counties, non-governmental organizations, researchers and students interested in exploring the effects of infrastructure and policy choices on community outcomes such as motorized and non-motorized accessibility, housing affordability, greenhouse gas emissions, and the protection of open space and environmentally sensitive habitats. The UrbanSim Overview and a Wikipedia Article summarize its design and features. Detailed descriptions are available in the Documentation and ResearchPapers on this site. If you have questions about this project, contact Paul Waddell.

UrbanSim is professionally supported by Synthicity, which has created a new architecture for UrbanSim that is designed to be smaller, faster, and more robust, while maximizing the ease of use for non-programmers and programmers alike. Installers are coming for this new version, and a web-based user interface that includes interactive mapping. Contact Synthicity for details and support.

Background

UrbanSim was initially designed by Paul Waddell in the mid-1990's, and implemented as a prototype in Oregon in 1998. It has been continuously refined and re-engineered since then with the cooperation of a Core Development Team, and a growing community of Research Collaborators contributes to the project. Its development has been made possible by generous support from the funders listed below. It is freely available on the Download Page as open source software using the GPL license. We do ask that users register on this website before downloading, so we can maintain some minimal information about the user community. Since its initial release in 1998, UrbanSim has increasingly been adopted for operational planning use in the U.S. and in Europe, Asia, and Africa, in planning agencies and in university research and educational settings. The user community and research collaborators directly and indirectly support the application and refinement of UrbanSim. This interactive web site provides a virtual meeting ground for users and developers of the system, with approximately half from the USA, and half from a rapidly growing list of countries:

Argentina, Armenia, Australia, Austria, Belgium, Belize, Bolivia, Brazil, Cambodia, Cameroon, Canada, Chile, China, Czech Republic, Ecuador, Egypt, Ethiopia, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Iran, Ireland, Israel, Italy, Jamaica, Japan, Jordan, Korea, Latvia, Lebanon, Lithuania, Luxembourg, Malaysia, Mexico, Moldovia, Morocco, Namibia, Netherlands, New Zealand, Nigeria, Oman, Pakistan, Philippines, Poland, Portugal, Russia, Saudi Arabia, Singapore, Slovenia, South Africa, Sri Lanka, Sweden, Switzerland, Taiwan, Thailand, Trinidad and Tobago, Turkey, Ukraine, United Arab Emirates, United Kingdom, USA, Venezuela, Vietnam

If you are interested in using UrbanSim or collaborating on its further development, please register on this web site and join the community. If you have questions regarding UrbanSim or this web site, email Paul Waddell at waddell (at) berkeley.edu or the mailing list.

State of the System

We use what is known as a Continuous Integration System to test and build the OPUS and UrbanSim software. As developers check in updates to the Subversion repository, this triggers a suite of tests that provide rapid feedback on whether those changes caused any tests to fail. This keeps the system continually in testing mode, and helps keep the code robust as it continues to evolve. To see what the state of the system is, follow the link below. Green lights mean that all the tests have passed for the package. A red light means one or more tests have failed. Note that there is a new implementation of UrbanSim being hosted on GitHub. Contact Synthicity for requests for assistance in developing an UrbanSim application for your region.
