Download and read online ebook Mobility Data-Driven Urban Traffic Monitoring write by Zhidan Liu. This book was released on 2021-05-18. Mobility Data-Driven Urban Traffic Monitoring available in PDF, EPUB and Kindle. 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.

Advances in Data-driven Models for Transportation available in PDF, EPUB and Kindle. With the rising popularity of ride-sharing and alternative modes of transportation, there has been a renewed interest in transit planning to improve service quality and stem declining ridership. However, it often takes months of manual planning for operators to redesign and reschedule services in response to changing needs. To this end, we provide four models of transportation planning that are based on data and driven by optimization. A key aspect is the ability to provide certificates of optimality, while being practical in generating high-quality solutions in a short amount of time. We provide approaches to combinatorial problems in transit planning that scales up to city-sized networks. In transit network design, current tractable approaches only consider edges that exist, resulting in proposals that are closely tethered to the original network. We allow new transit links to be proposed and account for commuters transferring between different services. In integrated transit scheduling, we provide a way for transit providers to synchronize the timing of services in multimodal networks while ensuring regularity in the timetables of the individual services. This is made possible by taking the characteristics of transit demand patterns into account when designing tractable formulations. We also advance the state of the art in demand models for transportation optimization. In emergency medical services, we provide data-driven formulations that outperforms their probabilistic counterparts in ensuring coverage. This is achieved by replacing independence assumptions in probabilistic models and capturing the interactions of services in overlapping regions. In transit planning, we provide a unified framework that allows us to optimize frequencies and prices jointly in transit networks for minimizing total waiting time.

Download and read online ebook Data-driven Condition Evaluation of Transportation Systems write by Agnimitra Sengupta. This book was released on 2023. Data-driven Condition Evaluation of Transportation Systems available in PDF, EPUB and Kindle. Transportation systems involve complex interactions with traffic demand, loading, and environmental factors, which result in non-linearities in system performance. The structural and functional conditions of a system determine its efficiency in meeting mobility demands. However, budget constraints impose serious limitations on actively monitoring these system responses to maintain reliability. Due to the intrinsic complexity of system responses and limited data availability, it is necessary to develop robust machine-learning models that can accurately characterize system performance and predict future states, based on which actions can be undertaken to maximize their performance under optimal settings. This dissertation focuses on the development and application of machine-learning strategies in evaluating and predicting the conditions of transportation systems like infrastructures using non-destructive evaluation (NDE) techniques, and road networks using real-time traffic data. Multi-dimensional NDE data that capture damage-specific signatures are interpreted to quantify the degree of damage and structural integrity in terms of condition ratings. Several spectral-based autonomous signal classification mechanisms and probabilistic sequential models like hidden Markov models, which perform well with limited data availability, have also been explored. Additionally, this dissertation contributes to the functional performance estimation of networks in terms of macroscopic traffic variables by analyzing real-time traffic datasets. In particular, it focuses on solving problems like traffic prediction and uncertainty quantification using advanced deep learning models, which are essential for efficient traffic operations and optimal control. Data-driven modeling-specific issues like data scarcity, synthetic data generation and transferability, and generalizability of the models on out-of-distribution datasets have been discussed in the context of both NDE and traffic data.
