Book Description
Transportation agencies have become very interested in traffic monitoring systems based on wireless location technology (WLT) since they offer the potential of collecting travel time data across a wide portion of the road system. Prior tests of WLT-based systems have been unsuccessful, in part because they have treated the road network as a homogeneous entity. This "area-wide" method has inherent limitations, causing congested roadways to be over sampled and uncongested and low volume roads to be under sampled. This project developed a methodology to estimate sampling parameters based on localized traffic conditions in the network, termed a "zonal approach." In zonal WLT systems, the roadway network is disaggregated into smaller areas, termed "zones," based on cellular coverage areas. In this research, two zonal sampling strategies were examined and tested using three simulated networks. When the road network is complex, the zonal priority sampling strategy was found to distribute probes throughout the network and produced a larger number of speed estimates on uncongested and low volume roads. Moreover, the zonal priority strategy improved speed estimation accuracy by 10 percent over the other two sampling strategies. For networks with simple geometry or uniform congested traffic conditions, there were no significant differences among the sampling strategies. The results of this research indicate that the homogeneous approach used by earlier deployments has limitations, and results could be potentially improved by tailoring sampling parameters to a more localized level.

Book Description
These volumes constitute the Proceedings of the 6th International Workshop on Soft Computing Applications, or SOFA 2014, held on 24-26 July 2014 in Timisoara, Romania. This edition was organized by the University of Belgrade, Serbia in conjunction with Romanian Society of Control Engineering and Technical Informatics (SRAIT) - Arad Section, The General Association of Engineers in Romania - Arad Section, Institute of Computer Science, Iasi Branch of the Romanian Academy and IEEE Romanian Section. The Soft Computing concept was introduced by Lotfi Zadeh in 1991 and serves to highlight the emergence of computing methodologies in which the accent is on exploiting the tolerance for imprecision and uncertainty to achieve tractability, robustness and low solution cost. Soft computing facilitates the use of fuzzy logic, neurocomputing, evolutionary computing and probabilistic computing in combination, leading to the concept of hybrid intelligent systems. The combination of such intelligent systems tools and a large number of applications introduce a need for a synergy of scientific and technological disciplines in order to show the great potential of Soft Computing in all domains. The conference papers included in these proceedings, published post conference, were grouped into the following area of research: · Image, Text and Signal Processing “li>Intelligent Transportation Modeling and Applications Biomedical Applications Neural Network and Applications Knowledge-Based Technologies for Web Applications, Cloud Computing, Security, Algorithms and Computer Networks Knowledge-Based Technologies Soft Computing Techniques for Time Series Analysis Soft Computing and Fuzzy Logic in Biometrics Fuzzy Applications Theory and Fuzzy Control Bussiness Process Management Methods and Applications in Electrical Engineering The volumes provide useful information to professors, researchers and graduated students in area of soft computing techniques and applications, as they report new research work on challenging issues.

Book Description
Today, citizens advocate greater environmental sustainability, better services and the improvement of urban quality by promoting safer mobility, especially for the most vulnerable road users. Addressing these issues, Town and Infrastructure Planning for Safety and Urban Quality contains papers presented at the XXIII International Conference “Living and Walking in Cities” (Brescia, Italy, 15-16 June 2017). The contributions discuss town planning issues, look at best practices and research findings across the broad spectrum of urban and transport planning, with particular attention to the safety of pedestrians in the city. The main topics of the book are: - Urban regeneration. A focus on walkability (vulnerable road users; boosting and planning soft mobility) - Road safety and urban planning - vulnerable road users: planning for safety (integrated land use and transport planning; methodological approaches and case studies; integrated tools for town and transport planning; shaping public spaces and walkability; transport solutions for tourism) - Innovative and traditional solutions for Italian cities - Extra-European approaches to town and infrastructure planning - Different perspectives in road safety: prevention, infrastructure, sharing - Advances in road safety Town and Infrastructure Planning for Safety and Urban Quality is a powerful plea for a multi-disciplinary and comprehensive approach to urban mobility and planning, and will be of interest to academics, consultants and practitioners interested in these areas.
