Multi-resolution Analysis of the Impacts of Complete Streets on Efficiency, Safety and Environment of Urban Corridors May 2018 – April 2020 A. Stevanovic (PI) Florida Department of Transportation Complete streets is a transportation policy and design approach that requires streets to be planned, designed, operated, and maintained to enable safe, convenient and comfortable travel and access for users of all ages and abilities regardless of their mode of transportation. Although there has been a dozen of relevant studies to address qualitative benefits of Complete Streets there are no studies which address quantitative assessment of these streets from both operational and planning perspectives. This project will fill a gap in the existing body of knowledge by: 1. Developing a multi-resolution modeling methodology which will take in consideration both long-term planning aspects of the Complete Streets as well as operational strategies which may be implemented to address specific needs of its multi-modal users; and 2. Investigating multi-criteria costs and benefits of deploying complete Streets in a number of scenarios with various Complete Street ‘use-cases’ and network topology.
Benefits of Adaptive Traffic Control Deployments – A Review of Evaluation Studies May 2018 – June 2019 A. Stevanovic (PI) National Academy of Sciences/ TRB – NCHRP (National Cooperative Highway Research Program) Adaptive Traffic Control Systems (ATCSs), have been in use since the late ‘70s but have received significant attention in the US only in the last 10 years. Although there are more than 150 deployments across the country, there are still many questions that remained unanswered about operational and safety benefits of these systems. Literature review clearly shows a shortage of comprehensive studies on variety of the field evaluations and categorization of those evaluations (e.g. based on a number of criteria). The goal of this project is to develop guidance for practitioners on evaluating, selecting, implementing, and maintaining ATCSs. The guidance should identify successful practices in ATCS application, systems integration, maintenance, and monitoring. It should also provide an intuitive tool to help practitioners assess performance and make objective-based decisions for appropriate implementation.
Impact of Accurate Assessment of Freeway Traffic Conditions on the Operations of I-95 Express Lanes in Broward County November 2017 – October 2018 A. Stevanovic (PI) Florida Department of Transportation Express-lanes operations depend on the accuracy of vehicle detectors for (Statewide Express Lanes Software) SELS to calculate a toll. Available literature review does not provide answers to the question – how much are toll impacted by imprecise and/or sparse detection? FDOT is interested in studying the effects of vehicle detector accuracy (manufacturer’s and actual), sampling size (time), sampling rates (frequency), number of detectors used, limitations inherent with point data extrapolated into 2D space, spacing of the detectors, and database averaging effects have on the SELS’s calculated toll. This research will investigate the impact of vehicle detection on the toll calculation and overall express lanes operations.
REU Site: Sensing and Smart Systems January 2017 – December 2019 A. Stevanovic (Co-PI) National Science Foundation This project will host cohorts of undergraduate students for summer research in the area of sensing and smart systems. Smart systems represent an emerging class of distributed systems that provide real-time awareness of conditions, trends, and patterns to support improved decision-making and automated control. More specifically at LATOM the REU students will work on two particular topics: 1. on establishing communication between virtual vehicle and traffic signal controller in a Connected Vehicle framework, and 2. on enabling integration of a physical driving simulator with a mathematical simulation model representing urban network operations. A driving simulator will be assembled from a gaming-like platform and peripherals, computer and three flat-screen monitors.
Development of a Traffic Map Evaluation Tool for TMC Applications February 2017 – December 2018 A. Stevanovic (PI) Florida Department of Transportation Develop a Mapping Evaluation Tool which will assist TMC operators to better monitor, analyze, and spot trends of arterial traffic operations. The tool will be built on common FDOT-approved framework and platforms which will ensure consistency (and lack of overlapping) with the other ongoing efforts. The tool is intended to cover a range of data and traffic monitoring procedures which are either emerging (e.g. high-resolution controller data) or being slightly neglected in the other applications and tools (drawbridge and RR preemption data).
Analysis of Traffic Demand Patterns and Signal Re-timing Strategies for ITS-data-rich Arterials January 2017 – May 2018 A. Stevanovic (PI) Florida Department of Transportation This research will bring a new perspective to the evaluation of robustness of signal timing plans for varying traffic conditions. FAU research team will incorporate long-term field data into the process of developing new signal timing plans which will be able to cope with variability of traffic conditions. This will be achieved by incorporating a comprehensive set of field traffic flows, after necessary validation and balancing, into a microsimulation model, thus creating realistic traffic-volume scenarios which will represent unique signatures of traffic flows. Signal timing plans will then be optimized for each of the representative traffic flows resembling the process that usually occurs in the state of practice. Then, each of the signal timing plans will be evaluated for multiple traffic-flow scenarios to determine the best signal timing plans.
