Available in PDF, EPUB and Kindle. Book excerpt: The late night low volume arterial roadway presents a specific signal aontrol problem. The control decision involves a trade off between the motorists on the artery and those on the cross streets. The motorists on the artery are irritated by frequent stops if signals are not coordinated, while those on the cross street are annoyed by a long waiting time if signals are coordinated. The choice between coordination and free operation is often subjective, especially when semi-actuated signals are involved. The paper presents a method to facilitate the choice between coordination and free operation on arterial roadways controlled by semi-actuated signals when traffic is light during off-peak hours. The decision is made based upon a disutility function which is a combination of the number of stops on the artery and the average cross street waiting time. A case study was performed to demonstrate the application of this methodology under the closed loop signal system in the City of Gainesville, Florida. The results indicate that this method provides a promising tool for arterial control with semi-actuated signals during late night hours.

Available in PDF, EPUB and Kindle. Book excerpt: This report documents research conducted to develop better strategies to use with traffic actuated control in coordinated signal systems. Recommendations are presented on more efficient strategies for coordination using actuated control. Representative arterial traffic control problems were modeled into a statistical testbed using TRAF-NETSIM. A set of scenarios covering a range of arterial geometry, traffic volumes and traffic actuated control settings were tested and evaluated. PASSER II-90 was used to develop base signal timing plans. Chapter One describes the various objectives that were intended to be achieved by this research. It also discusses signal coordination strategies for actuated control. Chapter Two presents the background information and various traffic engineering simulation models available for use in this study. Chapters Three and Four explain the study methodology adopted for this research and the results obtained for the various study scenarios, respectively. Chapter Five presents the conclusions and recommendations of the research.

Book Synopsis Traffic Signal Control Strategies for Pedestrians and Bicyclists by :
Download or read book Traffic Signal Control Strategies for Pedestrians and Bicyclists written by and published by . This book was released on 2022 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the United States, traffic signal timing is traditionally developed to minimize motor vehicle delay at signalized intersections, with minimal attention paid to the needs of pedestrians and bicyclists. The unintended consequence is often diminished safety and mobility for pedestrians and bicyclists. The TRB National Cooperative Highway Research Program's NCHRP Research Report 969: Traffic Signal Control Strategies for Pedestrians and Bicyclists is a guidebook that provides tools, performance measures, and policy information to help agencies design and operate signalized intersections in a way that improves safety and service for pedestrians and bicyclists while still meeting the needs of motorized road users. Supplemental to the report are presentations of preliminary findings, strategies, and summary overview.
Book Synopsis Development and Evaluation of an Arterial Adaptive Traffic Signal Control System Using Reinforcement Learning by : Yuanchang Xie
Download or read book Development and Evaluation of an Arterial Adaptive Traffic Signal Control System Using Reinforcement Learning written by Yuanchang Xie and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation develops and evaluates a new adaptive traffic signal control system for arterials. This control system is based on reinforcement learning, which is an important research area in distributed artificial intelligence and has been extensively used in many applications including real-time control. In this dissertation, a systematic comparison between the reinforcement learning control methods and existing adaptive traffic control methods is first presented from the theoretical perspective. This comparison shows both the connections between them and the benefits of using reinforcement learning. A Neural-Fuzzy Actor-Critic Reinforcement Learning (NFACRL) method is then introduced for traffic signal control. NFACRL integrates fuzzy logic and neural networks into reinforcement learning and can better handle the curse of dimensionality and generalization problems associated with ordinary reinforcement learning methods. This NFACRL method is first applied to isolated intersection control. Two different implementation schemes are considered. The first scheme uses a fixed phase sequence and variable cycle length, while the second one optimizes phase sequence in real time and is not constrained to the concept of cycle. Both schemes are further extended for arterial control, with each intersection being controlled by one NFACRL controller. Different strategies used for coordinating reinforcement learning controllers are reviewed, and a simple but robust method is adopted for coordinating traffic signals along the arterial. The proposed NFACRL control system is tested at both isolated intersection and arterial levels based on VISSIM simulation. The testing is conducted under different traffic volume scenarios using real-world traffic data collected during morning, noon, and afternoon peak periods. The performance of the NFACRL control system is compared with that of the optimized pre-timed and actuated control. Testing results based on VISSIM simulation show that the proposed NFACRL control has very promising performance. It outperforms optimized pre-timed and actuated control in most cases for both isolated intersection and arterial control. At the end of this dissertation, issues on how to further improve the NFACRL method and implement it in real world are discussed.

Download or read book Development and Evaluation of a Multi-agent Based Neuro-fuzzy Arterial Traffic Signal Control System written by Yunlong Zhang and published by . This book was released on 2007 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arterial traffic signal control is a very important aspect of traffic management system. Efficient arterial traffic signal control strategy can reduce delay, stops, congestion, and pollution and save travel time. Commonly used pre-timed or traffic actuated signal control do not have the capability to fully respond to real-time traffic demand and pattern changes. Although some of the well-known adaptive control systems have shown advantageous over the traditional per-timed and actuated control strategies, their centralized architecture makes the maintenance, expansion, and upgrade difficult and costly.
