Download or read book ITS Sensors and Architectures for Traffic Management and Connected Vehicles written by Lawrence A. Klein and published by CRC Press. This book was released on 2017-08-07 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: An intelligent transportation system (ITS) offers considerable opportunities for increasing the safety, efficiency, and predictability of traffic flow and reducing vehicle emissions. Sensors (or detectors) enable the effective gathering of arterial and controlled-access highway information in support of automatic incident detection, active transportation and demand management, traffic-adaptive signal control, and ramp and freeway metering and dispatching of emergency response providers. As traffic flow sensors are integrated with big data sources such as connected and cooperative vehicles, and cell phones and other Bluetooth-enabled devices, more accurate and timely traffic flow information can be obtained. The book examines the roles of traffic management centers that serve cities, counties, and other regions, and the collocation issues that ensue when multiple agencies share the same space. It describes sensor applications and data requirements for several ITS strategies; sensor technologies; sensor installation, initialization, and field-testing procedures; and alternate sources of traffic flow data. The book addresses concerns related to the introduction of automated and connected vehicles, and the benefits that systems engineering and national ITS architectures in the US, Europe, Japan, and elsewhere bring to ITS. Sensor and data fusion benefits to traffic management are described, while the Bayesian and Dempster–Shafer approaches to data fusion are discussed in more detail. ITS Sensors and Architectures for Traffic Management and Connected Vehicles suits the needs of personnel in transportation institutes and highway agencies, and students in undergraduate or graduate transportation engineering courses.

Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of the study was to determine to what extent different vendors' traffic controllers can be effectively used in closed-loop signal systems in a manner acceptable to TxDOT engineers and maintenance personnel. Specific objectives to meet the goal included: Objective 1: Identify current practices and needs of TxDOT engineers and maintenance personnel. Objective 2: Define alternatives for providing closed-loop type traffc signal systems. Objective 3: Evaluate the feasibility and cost of implementing alternative system architectures for closed-loop traffic controller type systems. The findings of the work included a recommendation for TxDOT to proactively be involved in the National Transportation for ITS Protocol (NTCIP) and begin deployment of NTCIP compatible systems as soon as practical. The communications study also included a recommendation that TxDOT should actively be involved in the development of Advanced Transportation Controller standards, including controllers, cabinets, and software.

This book was released on 1997 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project report summaries research and implementation of signal system communications and improved signal control. An investigation of available signal system communication technologies and media identified spread spectrum radio as an effective, inexpensive, and flexible alternative. As part of the project, a radio communications system was selected and installed at five signalized intersections along US 281 in Falfurrias, Texas. Closed loop system software was then installed to coordinate the previously isolated, actuated intersections. The end result was improved traffic control, improved traffic flow, and remote system monitoring for those responsible for signal maintenance. A second aspect of the project focused on developing real-time control functionality that would make use of the communications system. The Texas Department of Transportation's Dynamic Arterial Responsive Traffic System (DARTS) Specification provided a public domain, real-time signal coordination algorithm that suited this purpose. Simulators were developed by the Texas Transportation Institute to determine the effectiveness of DARTS installed in Falfurrias. Results show an average 18 percent reduction in travel time on US 281 and indicate the potential for DARTS to reduce arterial travel time. As an added project benefit, the simulation software developed for this project can be used to determine DARTS applicability at any given field site, and it can be used to train personnel in DARTS use and calibration.

This book was released on 2020-12-01 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major problems of both developed and developing countries is traffic congestion in urban road transportation systems. Some of the adverse consequences of traffic congestion are loss of productive time, delay in transportation,increase in transportation cost,excess fuel consumption, safety of people,increase in air pollution level and disruption of day-to-day activities. Researches have shown that among others, traditional traffic control system is one of the main reasons for traffic congestion at traffic junctions. Most countries through out the world use pre-timed / fixed cycle time traffic control systems. But these traffic control systems do not give an optimal signal time setting as they do not take into account the time dependent heavy traffic conditions at the junctions. They merely use a predetermined sequence or order for both signal phase change and time setting. Some times this also leads to more congestion at the junctions. As an improvement of fixed time traffic control method, fuzzy logic traffic control model was developed which takes into account the current traffic conditions at the junctions and works based on fuzzy logic principle under imprecise and uncertain conditions. But as a real life situation,in addition to uncertainty and impreciseness there is also indeterminacy in traffic signal control constraints which fuzzy logic can not handle. The aim of this research is to develop a new traffic signal control model that can solve the limitations of fixed time signal control and fuzzy logic signal control using a flexible approach based on interval-valued neutrosophic soft set and its decision making technique, specially developed for this purpose.We have developed an algorithm for controlling both phase change and green time extension / termination as warranted by the traffic conditions prevailing at any time.
