The report summarizes the processes and products from a study of the real-time traffic data generated from the Transportation Operations Centers (TOCs) in 10 cities in 2000. Automatically collected data was analyzed for data quality and completeness and a database prepared for the sections of instrumented freeway. The database format consists of traffic volume, lane occupancy and speed records for every freeway section for each 5-minute period of the year. Other inventory information such as section length, number of lanes, detector type and other characteristics were also collected. Several mobility and reliability measures were produced - all are based on travel time concepts. They examine the level of travel delay and mobility, as well as the variation in travel conditions from day-to-day through the year and between roadways in urban areas. A variety of illustration techniques and statistical analysis methods are included in the main report. An appendix was created for each city to show ways to provide detailed summaries of average and unusual conditions for corridors and the system. Current practice emphasizes the real-time uses of the data for operations purposes but, in many cities, does not include extensive use of the data for other purposes. If the products from real-time databases assist operators and planners, there will be more interest in making the effort to create and improve the data collection process and the databases.

Travel time is a crucial variable both in traffic demand modeling and for measuring network performance. The objectives of this study focused on developing a methodology to characterize arterial travel time patterns by travel time distributions, proposing methods for estimating such distributions from static information and refining them with the use of historical GPS probe information, and given such time and location-based distribution, using realtime GPS probe information to produce accurate path travel times as well as monitor arterial traffic conditions. This project set the foundations for a realistic use of GPS probe travel time information and presented the proposed methodologies through two comprehensive case studies. The first study used the Next Generation SIMulation (NGSIM) Peachtree Street dataset, and the second utilized both real GPS and simulation data of Washington Avenue, in Minneapolis, MN.

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.

During the past decade, the understanding that traffic noise is an increasingly serious risk has gained ever wider recognition. Noise is a very complex phenomenon in its physical aspect, as well as in its psychological and medical dimensions. In consequence, it is practically indispensable to measure, predict, or describe noise in a simplified way. For assessment of road traffic noise, the sampling, computation, modelling, analysis and interpretation tools were selected to give most realistic results. The study identified the areas of heavy noise environment due to road traffic movement and the risk zones. The large-scale assessment of the noise and eventually the noise maps under a spatial-temporal aspect in sufficient detail will be useful in serving as a strategic planning and noise reduction tool and as an aid for decision making on environmental noise matters. The study, its technique, database and outputs and outcomes will be helpful for the town administrator and planners for the effective noise control actions.
