Abstract:The primary goal of this research project is to lay the foundation for establishing a state-of-the-art Intelligent Transportation Systems (ITS)
lab at the Louisiana Transportation Research Center (LTRC), where data will be collected, analyzed, and reported as part of the ITS effort in
Louisiana. The ITS lab is envisioned to serve as a central repository for traffic data collected in the state of Louisiana. The data will be
transformed into useful information that is instrumental to procedures and applications that benefit the Department of Transportation and
Development (DOTD), the local government, and the general public. The lab is also anticipated to be a tool to retain, recruit, and inspire
interest in the field of advanced traffic management systems for students in Louisiana as well as potential graduate students from outside
Louisiana.
In this project, the research team highlighted the importance of ITS data and the significant efforts made by several state agencies and
universities in the past few years to establish similar robust data archival systems and make them available to stakeholders. Several
universities followed suit and established their own ITS labs to collect data to support their research needs. Examples were found in state
universities such as Portland State University, University of California at Irvine, Florida International University, Washington State
University, etc. Based on a thorough review and assessment of the existing hardware and communication infrastructure at the designated
location of the lab, several recommendations for hardware upgrades and software acquisition were identified. The project also identified the
necessary equipment and cost to build the lab. Moreover, to properly and securely maintain the continuous operation of the ITS lab, a set of
policies were recommended for the ITS lab users/operators.
As a proof of concept, the research team was successful in setting up an automated procedure to stream traffic data in real time from Baton
Rouge Advanced Traffic Management Center (ATMC) to LTRC every 30 seconds from a total of 62 detectors along the corridors of I-10, I-
12, and I-110 in the Baton Rouge area. Other data sources were also identified and include the southern region of Louisiana, which is
currently monitored by the ECONOLITE Data Collection and Management System (DCMS). Another viable data source that was identified
are weigh-in-motion (WIM) stations used throughout Louisiana for truck weight enforcement.
During the course of this project, the research team identified several applications that can be supported by the ITS data to be collected at the
lab. Such applications include, but are not limited to, highway incident detection and management, travel time estimation and prediction,
work zone management, ramp metering, crash analysis, new concepts such as managed lanes and congestion pricing, highway breakdown
and recovery analysis, traffic signal optimization, calibration of microscopic simulation models, implementation of new pavement design
procedures, and others.
