Monitoring of Traffic Signal System’s Performance and Reliability Based on the Data from ATMS.now Signal System Central SoftwareUnknown Date (has links)
The monitoring of traffic signal systems can be of great importance for identifying problems, self-assessment, budgeting, creating the strategy for future steps, etc. Monitoring procedure was developed through a set of dashboards with relevant signal performance and reliability measures. The dashboards were created to reflect performance and reliability of a specific signal system on a weekly or monthly level. The author used data from ATMS.now signal system central software to illustrate how similar dashboards could be developed from any central software to enable operators to promptly and efficiently monitor various parameters of traffic signals. The main outcome of the study is a pair of Excel dashboards accompanied with appropriate user manual. The dashboards represent the tool for monitoring which can be helpful in the process of evaluation for traffic signal systems. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

Framework for Integration of the Driving Simulator in Connected Vehicle EnvironmentUnknown Date (has links)
Research on connected vehicles (CV) has attracted attention in the last decade due
to numerous potential applications and challenges related to exchange of information
between the vehicles (and infrastructure). Most of the relevant studies focus on these
applications and challenges with the help of novel or existing simulation frameworks. The
simulation framework often contains the mobility and communication components, and
these components are frequently simplified. In this study, the authors aim to provide the
detailed information for developing a fully V2X capable infrastructure within the lab
environment. The physical components of the proposed infrastructure include: (i) userdriven
Driving Simulator (DS) with the embedded micro-simulation tool (MS); (ii) external
traffic signal controller (TSC); (iii) Road Side Unit (RSU) and omnidirectional antenna
attached to RSU; (iv) On-Board Unit (OBU) that is integrated within DS‘s cockpit. The
proposed framework can be used for advanced applications in the context of connected
vehicles. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

The Relationship Between Traffic Signals and Pedestrian, Bicyclist and Transit User Exposure in Urban AreasSlavin, Courtney Natasha 01 January 2013 (has links)
Improving the efficiency of traffic operations along arterials is currently a priority for many agencies as their roadway infrastructure is built out to the largest possible capacity within the urban environment. Many advanced systems are being implemented to optimize traffic signal timing. Air quality is typically not a consideration when these decisions are made. The relationship between exposure to air pollution and traffic signal timing has not been fully explored by other researchers. This study is the first research effort to combine detailed traffic signal timing data (at 5 second intervals) and air pollutant exposure data. Results show that longer green time along the busy arterial reduces pollutant levels, while increased volume per cycle increases pollutant levels. This research quantifies the factors that contribute to pedestrian, bicyclist, and transit user exposure at a busy intersection along an urban arterial. The factors include traffic signal timing, weather related variables, traffic volumes, and heavy vehicle and bus presence. Additionally, the impact of an adaptive traffic signal system on air quality is assessed to understand the implications of signal timing on air pollutant exposure.
