Much of land use and transportation planning aims to reduce traffic congestion. Comprehensive and policy relevant measures useful to land-use and transportation planning need to capture both land use and travel dimensions. This book focuses on the science and policy around the multi-modal concept of accessibility.
Computation of Travel Time Data for Access to Destinations Study : Report #8 in the Series

Category: Traffic estimation
Freeway travel time data is used as an important input for measuring travel reliability and accessibility. The goal of this project was to generate reliable travel time data using loop detector data from the Twin Cities' freeway network collected over the past 14 years for the Access to Destinations projects. Several difficulties exist: one year of loop data can be missing up to 31.7%, loop data does not include vehicle lengths or classification to use in speed calculations, and link travel time must be computed without knowing speed variability within the link. The three basic approaches used in this project for imputing speed data are linear regression, spatial imputation, and week-toweek temporal imputation. A new method was developed to estimate average vehicle length using volume, occupancy, free-flow speed, and speed limit data. Link travel times were calculated by dividing the distance between stations into thirds and using speed data from both stations. Overall (for the last fourteen years), the imputation increased the average amount of valid data from 81.7% to 98.6%. Travel time for a selected route was verified by comparing the resulting calculated travel times to manual travel times measurement information.
Around the world, researchers, policy makers, and practitioners are working to ensure cities and communities are prepared for the challenges and opportunities of aged and highly urbanised populations. Bringing together stakeholders from Asia, Australia, Europe, and North America, this book presents new evidence and critical reviews of current knowledge to promote ongoing discussions on: affordable and accessible housing to support ageing in place; built environment supports for health-enhancing physical activity and mobility; and planning and design strategies and approaches to promote healthy and active ageing in cities and communities. The book content is framed by socio-ecological models of ageing and well-being that emphasise the dynamic interconnections between people and environment. Contributions in this edited volume stem from the International Ageing Urbanism Colloquium, 2017, Singapore University of Technology and Design.

Blocking, Scalability, and Reliability
Author: Mohsen Jahanshahi,Fathollah Bistouni
This unique text/reference provides an overview of crossbar-based interconnection networks, offering novel perspectives on these important components of high-performance, parallel-processor systems. A particular focus is placed on solutions to the blocking and scalability problems. Topics and features: introduces the fundamental concepts in interconnection networks in multi-processor systems, including issues of blocking, scalability, and crossbar networks; presents a classification of interconnection networks, and provides information on recognizing each of the networks; examines the challenges of blocking and scalability, and analyzes the different solutions that have been proposed; reviews a variety of different approaches to improve fault tolerance in multistage interconnection networks; discusses the scalable crossbar network, which is a non-blocking interconnection network that uses small-sized crossbar switches as switching elements. This invaluable work will be of great benefit to students, researchers and practitioners interested in computer networks, parallel processing and reliability engineering. The text is also essential reading for course modules on interconnection network design and reliability.

With fifteen essays by scholars and professionals, from fields such as policy and law, Health and Well-being for Interior Architecture asks readers to consider climate, geography, and culture alongside human biology, psychology, and sociology. Since designers play such a pivotal role in human interaction with interior and architectural design, this book sheds light on the importance of a designer's attention to health and well-being while also acknowledging the ever changing built environment. Through various viewpoints, and over 30 images, this book guides designers through ways to create and develop interior designs in order to improve occupants' health and well-being.
