About the WisTransPortal Project
V-SPOC Project Information |
LCS Project Information
Department of Transportation (WisDOT) has a long history of collecting
transportation operations related data to support long-range planning and improvement
project justifications. WisDOT has also collected a significant amount of traffic data
that supports metropolitan Milwaukee and Madison freeway management systems.
To better support infrastructure-based and operations-oriented investment decisions,
there is a need to provide tools that effectively manage, aggregate, archive and analyze
multiple data sources and allow transportation professionals to practice methods for
accessing and manipulating the information. Another emerging need relates to the use of
aggregated data to provide real-time information to motorists, e.g., 511 traveler
To help meet those needs, the
Wisconsin Traffic Operations and
Safety (TOPS) Laboratory has started development of a data management system (WisTransPortal)
to facilitate continuous collection and archiving of Intelligent
Transportation Systems (ITS) data in Wisconsin. The basic mission of the WisTransPortal
project is to develop capabilities for a statewide ITS data hub to support multiple
applications in traffic operations and safety. Those capabilities include integration,
management, analysis, and dissemination of real-time and historical ITS / traffic operations
data through a centralized database and communications infrastructure.
The WisTransPortal is being developed through a phased deployment process by TOPS Lab
at the UW-Madison Department
of Civil and Environmental Engineering.
Phase I, which began in mid-2003, is focused primarily on hardware and system software
deployment and preliminary data archiving capabilities. Phase II is scheduled to begin
in late 2005 and will focus on expanded data archiving capabilities and applications
The WisTransPortal system architecture is based on a distributed model that separates
logical software components such as the high-level Web presentation, the mid-level
application logic, and the low-level data management. The benefit of this design is to
support the development of a wide range of user applications and to allow, at the same
time, for gradual improvements to the underlying database model. Highlights of the
WisTransPortal hardware and software configuration include:
- Direct link from WisTransPortal to the WisDOT fiber network.
- Oracle 10g Enterprise Database with one terabyte of hardware RAID disk storage.
- Off-site data backup services through the UW Division of Information Technology.
- J2EE web application development based on Apache/Tomcat and Open Source Java.
- ESRI ArcIMS for publishing GIS based-tools to the web.
Data Collection and Archiving
The data archiving component of WisTransPortal consists of automated services
that connect to various WisDOT and other ITS data sources and prepare the data for
archiving in a common Oracle database. Phase I development is focused
primarily on replicating existing data sources in the WisTransPortal. Five main
data elements are covered in the Phase I scope:
- Traffic detector data from the WisDOT Traffic Operations Centers (TOC) in
Madison and Milwaukee.
- Lane and ramp closure data from Milwaukee TOC.
- CAD/911 traffic incident data from Milwaukee TOC.
- Historical crash data from the WisDOT MV4000 crash database.
- Road weather information from WisDOT R/WIS system.
Phase II will focus on improvements to the underlying database model to support
data integration and national ITS standards. Additional development goals include
migrating existing data acquisition services to the WisDOT fiber link and improving
the data archiving component design through the use of J2EE data persistence frameworks.
A core business function of the WisTransPortal is to support ITS data clearinghouse
activities through the use of high-level interfaces to the data. This includes
the development of web-based query tools, GIS mapping tools, and web services.
In addition, there are several WisDOT applications that are currently being developed
or investigated for development through the WisTransPortal:
- Enhancements to the Milwaukee TOC Data Extractor software.
- Development of a statewide web-based Lane Closure System.
- Support for Wisconsin 511 traveler information.
- Local roads crash data mapping tools.
- WisDOT inconvenience map automation.
