This book was released on 2005 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the purpose of collecting travel times, GISTT (GPS-GIS Integrated System for Travel Time Surveys) is developed in this study. The study focuses on the development of a software package that collects the link travel time data both in static and dynamic modes. GPS (Global Positioning System) technologies have been increasingly used in various applications of transportation planning and operations. One such application is travel time studies. When combined with GIS (Geographic Information Systems), GPS data can be matched with spatial map features such as highways and roads for collecting travel times on those desired links. The static mode refers to the case where a previously dispatched vehicle equipped with a GPS data logger is used to collect travel times along a specified road. The dynamic mode refers to the real time monitoring of probe vehicles on the links using a GPS and Wireless-Internet equipped probe vehicle.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Travel time and delay are among the most important measures for gauging a transportation system's performance. To address the growing problem of congestion in the US, transportation planning legislation mandated the monitoring and analysis of system performance and produced a renewed interest in travel time and delay studies. Current techniques for collecting travel time and delay data range from manual data logging to completely automated, computer-aided record keeping. The techniques employed by the University of Delaware have evolved into a semi-automated system, but human and computer error still have the potential to create inaccuracies. In order to eliminate opportunities for human and computer error, a new GPSbased data collection technique was employed and compared directly with the currently accepted data collection methods. By simultaneously collecting data using three different techniques, the accuracy of the GPS positioning data and the resulting travel time and delay values could be objectively compared for automation and statistically compared for accuracy. It was found that the new technique provided the greatest automation requiring minimal attention of the data collectors and automatically processing the data sets. Using the Analysis of Means, Variances, Wilcoxon Signed Rank Test, and Pearson and Spearman Correlation Analyses, overall results showed that all data collection methods perform equally well for both travel time and delay time measurements.

This book was released on 2013-08-23 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamics of Information Systems: Algorithmic Approaches presents recent developments and results found by participants of the Fourth International Conference on the Dynamics of Information Systems, which took place at the University of Florida, Gainesville FL, USA on February 20-22, 2012. The purpose of this conference was to bring together scientists and engineers from industry, government, and universities to exchange knowledge and results in a broad range of topics relevant to the theory and practice of the dynamics of information systems.Dynamics of Information plays an increasingly critical role in our society. The influence of information on social, biological, genetic, and military systems must be better understood to achieve large advances in the capability and understanding of these systems. Applications are widespread and include: detection of terrorist networks, design of highly efficient businesses, computer networks, quantum entanglement, genome modeling, multi-robotic systems, and industrial and manufacturing safety. The book contains state-of-the-art work on theory and practice relevant to the dynamics of information systems. It covers algorithmic approaches to numerical computations with infinite and infinitesimal numbers; presents important problems arising in service-oriented systems, such as dynamic composition and analysis of modern service-oriented information systems and estimation of customer service times on a rail network from GPS data; addresses the complexity of the problems arising in stochastic and distributed systems; and discusses modulating communication for improving multi-agent learning convergence. Network issues—in particular minimum-risk maximum-clique problems, vulnerability of sensor networks, influence diffusion, community detection, and link prediction in social network analysis, as well as a comparative analysis of algorithms for transmission network expansion planning—are described in later chapters.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Similar to other market segments, transportation technologies continue to emerge, advance and blossom affording researchers and practitioners the ability to challenge established principles and discover new horizons. This thesis aims to investigate the use of Bluetooth and smartphone Global Positioning System (GPS) data to compute travel times (or delays) and analyze the influence of some factors such as weather and the built environment. This work demonstrates the practical applicability of the new sources of data against more traditional technologies and methods.First, Bluetooth data collected along a major arterial during the winter period was used to assess the impact of weather variables on travel speeds. This research is based on data from 2013-2015 collected from permanent sensors installed along one of the main urban arterials in Montreal, Canada. The effects were modeled at an hourly level using a mixed regression model considering the temporal variation of speed throughout a day. The results confirmed the major importance of snow as a hindrance to travel with a speed drop greater than 1.5 kilometers per hour (km/h) for an average snowfall. As predicated in the literature, the effect of rain had the next highest negative impact with a decrease in speed of 0.46-0.67 km/h for an average hourly rainfall. The impacts of temperature and visibility had positive benefits to speed while increasing wind speeds expectedly reduced speeds although; the magnitudes of their effects were small. Overall, the effects of the weather variables were slightly smaller than what has been reported in the literature which has typically been focused on highway environments.Second, an investigation was launched into whether Bluetooth / WiFi duration times at intersections could be used to estimate vehicle delay using GPS and manually processed video data. All data were collected over four days in May and June 2016. Average delay times from the video and sensor data were then computed for 15, 30 and 60 minute intervals. First-order regression models from the GPS data revealed fairly high fit scores of 68 - 96 % indicating that the sensor duration times do match actual driver delay. Similarly, regression models between the video and duration data resulted in fairly high fit scores of 70 % at the 15 minute level indicating that the sensors can competently monitor the temporal variation of delay. These results are promising given the low costs and ease of installation of these technologies, but need further validation to illustrate their practical potential to estimate intersection delay. Lastly, driver GPS data collected from a smartphone application activated from a large sample of drivers in Quebec City was used to compare the driving costs of travelling between different neighborhood typologies. The driving costs were defined as travel time, fuel consumption and greenhouse gas emissions. The four neighborhood typologies defined were developed using four built environment attributes: Population density, employment density, land-use mix, and transit accessibility. An analysis of the monetary travel costs revealed that trips originating from the rural / suburban region had trip costs 24-30% higher than other regions." --
