    Activation of the I-394 Laboratory for ITS Operational Testing: Phase 2
    (Center for Transportation Studies, University of Minnesota, 1998-04) Reynhout, Kenneth; Michalopoulos, Panos; Siagian, Alexander
    The key element in improving traffic operations and performing real-time management is the ability to assess the effectiveness of various alternatives prior to implementation. Likewise, the crucial feature for providing this capability is a Traffic Data Management System (TDMS), which gathers data and makes it available for various traffic analysis applications. The purpose of this research is to develop TDMS as part of a Laboratory Environment for TRaffic ANalysis (LETRAN). Such a laboratory environment would provide easy and efficient access to various kinds of traffic data for use in simulation, control, incident detection, and other types of traffic analysis applications to be deployed in a next-generation traffic management center. In addition, a Machine-Vision Laboratory (MVL) will be designed and implemented as part of the Center for Transportation Studies(CTS) Intelligent Transportation Systems Laboratory (ITS Lab). This MVL will use live video feeds from both freeways and arterial streets and provide machine-vision technology for conducting traffic detection, data collection, and group training exercises. Such capabilities will allow for the collection of detailed, accurate, and continuous data for successful model development, calibration, testing and evaluation.

    Activation of the I-394 Laboratory for ITS Operational Testing: Phase I
    (Center for Transportation Studies, University of Minnesota, 1997-12) Reynhout, Kenneth; Michalopoulos, Panos; Sullivan, Mike; Siagian, Alexander
    This and other related research have two primary objectives: 1. To develop practical operational tools which can be deployed for use in traffic-management and transportation planning activities. 2. To develop a laboratory infrastructure which will facilitate future advances in traffic modeling and other ITS initiatives. The objectives of this particular research project are as follows: * A thorough examination and documentation of the 1-394 system's specifications. * Diagnosis of the working condition of the 1-394 system. * Negotiation and implementation of a repair plan * Establishing a communications connection between the ITS Lab and the Traffic Management Center (TMC). * Activation of the 1-394 Lab, which will include a user's guide that describes the steps a user should take to access video, make a connection to the TMC and the 1-394 system, and configure the system for traffic detection and data collection. A completed 1-394 Lab would be a unique and valuable tool for obtaining information that loop-detectors have been unable to supply. This information includes flow dynamics, incident behavior, capacity, and other traffic-flow characteristics. This information is vital for fine tuning operational tools and schemes to be deployed in a future TMC, and will also provide an information foundation for future research and development.
