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.

This book was released on 2023-01-01 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data envelopment analysis (DEA) is a non-parametric approach for the estimation of production frontier that is used to calculate the performance of a group of similar decision-making units (DMUs) which employ comparable inputs to produce related outputs. However, observed values might occasionally be confusing, imprecise, ambiguous, inadequate, and inconsistent in real-world applications. Thus, disregarding these factors may result in incorrect decision-making. Thus neutrosophic sets have been created as an extension of intuitionistic fuzzy sets to represent ambiguous, erroneous, missing, and inaccurate information in real-world applications. In this study, we have proposed a technique for solving the neutrosophic form of the Charnes–Cooper–Rhodes (CCR) model based on single-value trapezoidal neutrosophic numbers (SVTrNNs). The possibilistic mean for SVTrNNs is redefined and applied the Mehar approach to transforming the neutrosophic DEA (Neu-DEA) model into its corresponding crisp DEA model. As a result, the efficiency scores of the DMUs are calculated using different risk parameter values lying in [0, 1]. A numerical example is given to analyze the performance of the all India institutes of medical sciences and compared it with Abdelfattah’s ranking approach.

This book was released on 1978 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comparative study of 5 signal timing control methods indicated that the most efficient method of signal control is the micrioprocessor which would allow an intersection to operate under actuated control during certain periods of the day and under predetermined timing patterns during other periods. The 5 signal timing methods considered were: Traffic Engineering Method, FHWA Design Manual Method, Fully Actuated Operation Method, Microprocessor with lagging Left-Turn Method, and Microprocessor with Leading Left-Turn Method. The "before" and "after" evaluation of these methods was made by pairing them in a series of six comparisons using time-lapse photography to supply vehicle data. The site selected for application of these comparisons was the Diamond Interchange of Interstate 95 Golfair Boulevard in Jacksonville, Florida. The study procedure is appropriate for signal timing studies made at: a diamond interchange, other interchange configurations with a ramp terminal and nearby signalized intersections, and a 2-way major street intersected by one or more one-way street pairs.

This book was released on 2015 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Different traffic signal control systems are applied nowadays. They vary in complexity and approach but mostly aimed at improving the intersection level of service and the efficiency of the traffic network. Fuzzy Logic Models (FLM) have been widely regarded as quite appealing for real-time applications, in addition to their explicit considerations for stochasticities or uncertainties of traffic measures. The majority of the FLMs for signal control were developed to handle isolated intersections in specific. Very few of these FLM systems explicitly account for neighbor intersections' traffic impact on the decisions to be made at the underlying intersections. The aim of this research is to develop a fuzzy logic control system for real time signal control that accounts for various traffic conditions. The system is envisaged to demonstrate signal control settings close to those developed by optimization methodologies. The literature review highlighted the structure of the existing FLMs for traffic signal control, input and output parameters and testing. The simulation environment (SYNCHRO) was utilized to model and design the traffic signals of an isolated intersection using 289 different traffic configurations and traffic volumes. The cases were carefully selected to cover the domain of different levels of service along the competing approaches. A FLM was developed and calibrated to emulate the Highway Capacity Manual (HCM) method for optimal signal control. The general outcome was that the proposed FLM is effective in replicating "optimization" signal control procedures (SYNCHRO). The devised FLM was thoroughly evaluated against the benchmark solutions of optimal cycle times, green times of the various phases. Further analysis was carried out to validate the devised FLM and to assess its effectiveness if deployed in conditions other than those conditions used model calibration. The validation results indicated that the FLM is mostly effective for cases of medium or high downstream congestion and medium to high traffic flows.

Oversaturated traffic conditions occur when the average traffic demand exceeds the capacity of the signal system. The dynamic optimization model proposed is the principal product of this research. The control objective of the dynamic model is to provide maximum system productivity as well as minimum delay for a selected roadway system. A special feature predetermined upper limits.
