Past Projects

Project Title Research Period PIs Sponsor Research Objective
Evaluation of Technologies to Support Multimodal Operations in Southeastern Florida September 2015 – May 2017 A. Stevanovic Florida Department of Transportation Investigate the use of crowd monitoring system/software to develop non-drivers’ (peds, bikes, etc.) set of performance metrics, which can be used to monitor and manage arterial operations in urban networks. Development/refine relevant performance dashboard, which would inform decision makers of the most relevant metrics retrieved from potential systems (e.g. Placemeter, STRAVA). Investigate the use of travelers’ incentive methods and applications available in the other parts of the country and the world. Focus should be given on literature review of the available systems which are already in practical use and not only in theoretical frameworks. This objective should encompass investigation of legislative barriers and supports for similar traveler’s incentive policies. It should also take in consideration local conditions in SE Florida where there may exist commuting modes not available elsewhere.

Stevanovic Florida Department of Transportation Document practices of using performance measures to monitor the quality of operations and maintenance of traffic signal systems, for various signal-operating agencies in Florida. The manual will be accompanied with a simple practical spreadsheet tool which will allow users to track performance of their systems and base their resource-investment decision on a set of measurable and quantitative assessments.
Development of Minimum Standards for Event-Based Data Collection Loggers and Performance Measure Definitions for Signalized Intersections March 2015 – December 2016 A. Stevanovic Florida Department of Transportation Develop a set of specifications that will define enumerations (e.g. type, size, frequency) required for traffic controller data logging and reporting as well as methods to convert this data into real-time performance measures. The specifications will apply to all current and future controllers with high-resolution event-based data logging capabilities, to ensure transferability of controllers’ outputs into traffic signal performance measures adopted by the Department.
400 South Corridor Assessment Study – Phase 2 September 2015 – September 2016 M. Zlatkovic (PI), A. Stevanovic (Co-PI) University of Utah (UTA & UDOT) Develop multimodal network of SLC downtown area to assess and determine impacts from current and proposed transit routes on the existing system, as well as to analyze traffic circulation along the main corridors and major intersections in the vicinity. Two major networks will be added to the existing network modeled in Stage 1 of this research. The first network will span through SLC downtown between West Temple and 600 W, and 100 S and 400 S. The second network will consist of State Street, 700 E, 1300 E and Foothill Blvd, between 400 S and 2100 S (I-80), which are the three major N-S corridors that carry traffic to and from Downtown SLC and the University of Utah. The research team will use VISSIM microsimulation software to determine measures of effectiveness along these corridors and major intersections. The study will include private cars, TRAX train analysis (with and without the Black Line), major bus routes (especially along 200 S), and non-motorized traffic (pedestrians and bicyclists).
Accessing Information about Transportation Systems Management and Operations Performance Measurement February 2015 – February 2016 A. StevanovicA. Stevanovic (PI), Co-PIs: M. Pack (UMD), M. Hallenbeck (UW), L. Elefteriadou National Cooperative Highway Research Program Establish a framework for organizing information about research and practices for TSMO performance measurement and monitoring to assess the impacts of TSMO strategies, concentrating on those aspects of TSMO that are less well developed or most difficult to measure.Facilitate practitioner access to such information by developing a guide to the most relevant recent literature. Describe the problems, opportunities, and consequences for practitioner adoption of specific measures and setting targets for TSMO performance management, with particular attention to federal rule-making under MAP-21 legislation.
Evaluation of Advanced Traffic Management Systems on SR 112/41st Street January 2015 – January 2016 A. Stevanovic City of Miami Beach Comparatively evaluate multiple adaptive traffic control logics in simulation environment.

Stevanovic Florida Department of Transportation Implement and refine the signal retiming and traffic demand prediction methods and procedures (developed in Phase 1 of the project) in the Traffic Management Center (TMC) environment for Broward County. Extend the methodology developed under Phase 1 to areas like West Palm Beach downtown where there is a common level of traffic sensors deployed in the field.

Stevanovic National Science Foundation Develop a vehicular networking unit (both OBU & RSU) containing all the hardware and software to research and develop sophisticated wireless systems for the next generation of transportation technology. Develop a platform that will combine the ad-hoc networking capabilities of IEEE 802.11p with WAVE with centralized cellular communications. The equipment will contain navigation sensors, human-machine interface (HMI) components, and traditional communication ports such as RS-232, USB, and WiFi to communicate with tethered equipment.

Leidos/Federal Highway Administration Develop preliminary methodology for identification of causal factors for congestion on arterial streets. The methodology will be executed through a couple of case studies where signalized arterials with various ITS equipment and significantly different operational backgrounds are analyzed to determine contributions of major causes of congestion.
