Demand Responsive Signal Control Strategy (Drsc) Incorporating Queue Length Information In Real-Time Signal Control, Rahul Rajbhara Jul 2012

Demand Responsive Signal Control Strategy (Drsc) Incorporating Queue Length Information In Real-Time Signal Control, Rahul Rajbhara

Civil & Environmental Engineering Theses & Dissertations

Most of the existing vehicle detection systems, namely inductive loops, video cameras etc. are incapable of measuring the queue lengths at signalized intersections. However, with the advent of modern technology, newer detection methods such as probe vehicles equipped with wireless communications (Connected Vehicles), particularly under the Vehicle Infrastructure Integration [52), and radar detection currently provide this capability [53). This thesis presents a Demand Responsive Signal Control Strategy (termed as DRSC) for an isolated signalized intersection. The control strategy incorporates real-time queue length information (obtained from probe vehicles) into the signal control logic. Demand based maximum green time for each upcoming/new …


Integrating Probe Vehicles And Stationary Detector Data To Construct Accurate Cumulative Curves To Study Bottlenecks, Khairul Azfi Anuar Apr 2012

Integrating Probe Vehicles And Stationary Detector Data To Construct Accurate Cumulative Curves To Study Bottlenecks, Khairul Azfi Anuar

Civil & Environmental Engineering Theses & Dissertations

Advancements in sensors technologies have given researchers and practitioners access to an immense amount of traffic data from multiple types of sensors. However, because of the diversity of the data types, developing a relationship between the different data sources can be challenging. To further complicate the issue, the presence of error or noise makes it difficult to infer any reliable conclusions from the data. To develop a relationship between different data sources, a new methodology is proposed in this thesis for fusing stationary detector data and probe vehicle data to construct an accurate cumulative curve. To remove or to reduce …


Cross-Year Comparison Of Life In Hampton Roads Survey Results, Social Science Research Center, Old Dominion University Jan 2012

Cross-Year Comparison Of Life In Hampton Roads Survey Results, Social Science Research Center, Old Dominion University

Life in Hampton Roads Survey Report

The Social Science Research Center (SSRC) at Old Dominion University recently completed data collection for the third annual Life in Hampton Roads telephone survey. The purpose of the survey was to gain insight into residents’ perceptions of the quality of life in Hampton Roads. The survey also attempted to determine the attitudes and perceptions of citizens regarding topics of local interest such as transportation and traffic, local and state government, crime, and other issues. Funding for the 2012 survey was provided by the ODU Office of Research and the Dean of the College of Arts and Letters. Questions were generated …
