Analyzing Benefits Of Connected Vehicle Technologies During Incidents On Freeways And Diversion Strategies Implementation: A Microsimulation-Based Case Study Of Florida's Turnpike, Francisca P. Kasubi

UNF Graduate Theses and Dissertations

The full utilization of connected vehicles (CVs) is highly anticipated to become a reality soon. As CVs become increasingly prevalent in our roadway network, connected technologies have enormous potential to improve safety. This study conducted a microscopic simulation to quantify the benefits of CVs in improving freeway safety along a 7.8-mile section on Florida’s Turnpike (SR-91) system. The simulation incorporated driver compliance behavior in a CV environment. The simulation was implemented via an existing VISSIM network model partially developed by the Florida Department of Transportation (FDOT). In addition, the study analyzed how CVs would assist in detour operations as a …

Exploring The Use Of Drones For Conducting Traffic Mobility And Safety Studies, Abdallah N. Kinero

UNF Graduate Theses and Dissertations

ABSTRACT

Advanced traffic data collection methods, including the application of aerial sensors (drones) as traffic data collectors, can provide real-time traffic information more efficiently, effectively, and safely than traditional methods. Traffic trajectory data like vehicles’ coordinates and point timestamps are challenging to obtain at intersections using traditional field survey methods. The coordinates and timestamps crucial in calculating trajectories can be obtained using drones and their particular integrated software. Thus, this study explores the use of unmanned aerial systems (UAS), particularly tethered drones, to obtain traffic parameters for traffic mobility and safety studies at an unsignalized intersection in Tallahassee, Florida. Tethered …

A Microscopic Simulation Approach For Developing Ramp Metering Activation Guidelines For Weekends, Sarah T. Kasomi

UNF Graduate Theses and Dissertations

Traffic congestion is one of the major concerns in urban motorways. Agencies are implementing various Transportation Systems Management and Operations (TSM&O) strategies to reduce traffic congestion on roadway networks. Ramp metering is a TSM&O strategy that utilizes signals installed at freeways’ on-ramps to dynamically manage traffic entering the freeway. RMSs have been effective at alleviating recurring congestion. Recurring congestion, however, constitutes less than half of all congestion. More than half of all congestion is due to non-recurring events such as incidents, work zones, adverse weather conditions, special events, etc., that adversely affect the performance of a highway. Non-recurring congestion on …
