Download or read book Mobility Data Driven Urban Traffic Monitoring written by Zhidan Liu and published by Springer Nature. This book was released on 2021-05-18 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the concepts of mobility data and data-driven urban traffic monitoring. A typical framework of mobility data-based urban traffic monitoring is also presented, and it describes the processes of mobility data collection, data processing, traffic modelling, and some practical issues of applying the models for urban traffic monitoring. This book presents three novel mobility data-driven urban traffic monitoring approaches. First, to attack the challenge of mobility data sparsity, the authors propose a compressive sensing-based urban traffic monitoring approach. This solution mines the traffic correlation at the road network scale and exploits the compressive sensing theory to recover traffic conditions of the whole road network from sparse traffic samplings. Second, the authors have compared the traffic estimation performances between linear and nonlinear traffic correlation models and proposed a dynamical non-linear traffic correlation modelling-based urban traffic monitoring approach. To address the challenge of involved huge computation overheads, the approach adapts the traffic modelling and estimations tasks to Apache Spark, a popular parallel computing framework. Third, in addition to mobility data collected by the public transit systems, the authors present a crowdsensing-based urban traffic monitoring approach. The proposal exploits the lightweight mobility data collected from participatory bus riders to recover traffic statuses through careful data processing and analysis. Last but not the least, the book points out some future research directions, which can further improve the accuracy and efficiency of mobility data-driven urban traffic monitoring at large scale. This book targets researchers, computer scientists, and engineers, who are interested in the research areas of intelligent transportation systems (ITS), urban computing, big data analytic, and Internet of Things (IoT). Advanced level students studying these topics benefit from this book as well.

Available in PDF, EPUB and Kindle. Book excerpt: The problems of urban traffic in the industrially developed countries have been at the top of the priority list for a long time. While making a critical contribution to the economic well being of those countries, transportation systems in general and highway traffic in particular, also have detrimental effects which are evident in excessive congestion, high rates of accidents and severe pollution problems. Scientists from different disciplines have played an important role in the development and refinement of the tools needed for the planning, analysis, and control of urban traffic networks. In the past several years, there were particularly rapid advances in two areas that affect urban traffic: 1. Modeling of traffic flows in urban networks and the prediction of the resulting equilibrium conditions; 2. Technology for communication with the driver and the ability to guide him, by providing him with useful, relevant and updated information, to his desired destination.

Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides an extended overview of modelling and control approaches for freeway traffic systems, moving from the early methods to the most recent scientific results and field implementations. The concepts of green traffic systems and smart mobility are addressed in the book, since a modern freeway traffic management system should be designed to be sustainable. Future perspectives on freeway traffic control are also analysed and discussed with reference to the most recent technological advancements The most widespread modelling and control techniques for freeway traffic systems are treated with mathematical rigour, but also discussed with reference to their performance assessment and to the expected impact of their practical usage in real traffic systems. In order to make the book accessible to readers of different backgrounds, some fundamental aspects of traffic theory as well as some basic control concepts, useful for better understanding the addressed topics, are provided in the book. This monograph can be used as a textbook for courses on transport engineering, traffic management and control. It is also addressed to experts working in traffic monitoring and control areas and to researchers, technicians and practitioners of both transportation and control engineering. The authors’ systematic vision of traffic modelling and control methods developed over decades makes the book a valuable survey resource for freeway traffic managers, freeway stakeholders and transportation public authorities with professional interests in freeway traffic systems. Advances in Industrial Control reports and encourages the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.

However, transport system is still facing many challenges, such as the traffic congestion issue. With recent advancements in sensor technologies, urban traffic monitoring system is capable of collecting traffic information from new data sources to mitigate these challenges. Traffic information can be used for both real-time traffic management and long term transport planning. Nonetheless, data sparseness is a common issue among these traffic sensor data, which leads to inaccurate or even mistaken results for higher-level traffic data analysis. To solve the data sparseness issue of traffic sensors, real-world floating car data from Wuhan city is collected and examined in this research. By extracting link-based average traffic speed for road links at different time intervals, an incomplete traffic condition matrix is formulated with missing entries due to the data sparseness issue. The research question can be posed as how to interpolate the missing entries from known sample in the traffic condition matrix. The literature shows that the typical traffic interpolation models are vulnerable to high data loss. On the contrary, compressive sensing based interpolation models in the literature can still perform well under high data loss. However, current compressive sensing based traffic interpolation models are too general owing to their data-driven strategies. A spatial and temporal regularized compressive sensing model is proposed to fill in the research gap identified from the literature. The model framework is established primarily based on current compressive sensing interpolation models. Using non-negative matrix factorization, the traffic condition matrix can be decomposed into the spatial factor matrix and temporal factor matrix. The model framework further employs the spatial and temporal constraints on the two factor matrices respectively, such as the spatial correlation, network topology, and short-term stability. The proposed model is equivalent to an optimization problem that minimizes errors with the constraints from low rank and spatio-temporal properties. Stochastic gradient descent algorithm is provided to solve the minimization problem of the proposed model. The proposed model is evaluated using root mean square error with a 5-fold cross validation. The proposed model is competed with temporal KNN model, space-time KNN model, Kriging model, and baseline compressive sensing model under different data loss patterns and data loss ratios (e.g. from 50% to 90%). Results show that the proposed model performs generally better than these models under these scenarios. This research establishes a paradigm for regularized compressive sensing interpolation models. The regularization terms on the spatial factor matrix and temporal factor matrix can be substituted with alternative constraints from domain knowledge. With further extensions, the proposed model has potential to be applied in several future studies such as the traffic data compression and traffic prediction.
