The Wisconsin 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., through deployment of a Wisconsin 511 automated traveler information system.
The WisTransPortal Project was launched through a partnership of WisDOT and the University of Wisconsin-Madison to develop capabilities for a statewide highway operations data center. The core mission of the project is to prototype technologies for Intelligent Transportation Systems (ITS) data integration. The applications that are being developed through the project include an archived data management system (ADMS) for transportation data mining as well as real-time data acquisition and dissemination systems to support highway operations and advanced traveler information interfaces. The WisTransPortal is being developed as a multi-year, multi-phase deployment by the Traffic Operations and Safety (TOPS) Laboratory at the UW-Madison College of Engineering campus.
The WisTransPortal offers a state-of-the-art deployment to support enterprise level application development. The current Phase I deployment started in late 2004 and is expected to continue through mid-2005. The system architecture consists of a distributed Dell PowerEdge / Windows Server 2003 local network inside the UW College of Engineering. A direct connection to the WisDOT fiber network is also being deployed. In addition to the UW firewall, the WisTransPortal manages its own local firewall for data security. The data management system is based on Oracle Database 10g Enterprise Edition with one terabyte of hardware RAID mirrored disk storage. Off-site data backup services are handled through the UW Division of Information Technology. Additional technologies include Apache / Tomcat for Java Enterprise web application development and ESRI ArcIMS for publishing GIS based-tools to the web.
In addition to supporting the basic research mission of the UW Civil and Environmental Engineering department, the WisTransPortal is developing several applications to provide operations support for WisDOT central office and the Transportation Operations Centers (TOCs) in Milwaukee and Madison. Those applications include:
- Enhancements to the Data Extractor / Ramp Meter Timing Facility: The Milwaukee TOC currently maintains a desktop application to analyze roadway traffic conditions for applications in traffic engineering and traveler information. The WisTransPortal enhancements include development of a new web-based interface, expansion of the current facility to handle Madison TOC and eventually statewide traffic data, and a goal to make the new system available to other states. This project also includes long-term archiving of TOC data, including roadway detector data, traffic incident data, lane closures and other planned events data, and ITS network configuration data.
- On-line Lane Closure System: The WisTransPortal team is planning
for the development of a web-based lane closure system to automate
the lane closure submission and approval process in Wisconsin. That
process is currently handled by District and TOC operators that
manually update the lane closure databases. The new system would
also automate the dissemination of lane closure data for
applications inside WisDOT, such as the Oversize / Overweight Truck
Permitting system.
- Inconvenience Map: WisDOT currently publishes a statewide
construction map for use by the trucking industry and others.
Production of this map is moving to the WisTransPortal, which will
include on-line access and automated re-routing tools.
- Wisconsin 511 Traveler Information: The WisTransPortal team was
a collaborator of the WisDOT 511 working group which has studied the
capabilities for deploying 511 in Wisconsin. Indeed, the core goal
of the WisTransPortal project, which unifies the above mentioned
projects, is to integrate ITS and other operations data in
Wisconsin. The WisTransPortal has been identified as a potential
candidate to provide the 511 condition reporting system backend.
- Crash Data Mapping: Crash location mapping is essential for
developing effective strategies and countermeasures to mitigate
crash hazards. Moreover, almost all the top ten safety issues and
safety emphasis areas identified in the Wisconsin Strategic Highways
Safety Plan (SHSP) have direct or indirect connections with crash
locations. The TOPS Lab is investigating the ability to develop
crash analysis tools through the WisTransPortal.
- The WisTransPortal has also been targeted to develop linkages with the Gary-Chicago-Milwaukee (GCM) Gateway and Wisconsin public safety networks.
