"Reliability of transport, especially the ability to reach a destination within a certain amount of time, is a regular concern of travelers and shippers. The definition of reliability used in this research is how travel time varies over time. The variability can apply to the travel times observed over a road segment during a specific time slice (e.g., 3 to 6 p.m.) over a fairly long period of time, say a year. The variability can also pertain to the travel times of repeated trips made by a person or a truck between a given origin and destination. Agencies are increasingly aware of the issue of reliability, although the transportation industry as a whole as yet lacks a firm understanding of the causes and solutions to failures of reliability. As the agenda for the SHRP 2 research on travel time reliability took shape, it became clear a fundamental study was required to be able to talk about travel time reliability in a meaningful way"--Foreword.

TRB's second Strategic Highway Research Program (SHRP 2) Report S2-L06-RR-2 Guide to Improving Capability for Systems Operations and Management examines the way transportation agencies should be organized to successfully execute operations programs that improve travel time reliability. After the guide was submitted for publication, the American Association of State Highway and Transportation Officials (AASHTO) converted the SHRP 2 Reliability Project L06 research into a web-based tool that is designed to be user-friendly, easy to access, and updatable. The web tool, Systems Operations and Management Guidance, is available on the AASHTO website at http://www.aashtosomguidance.org.

"The purpose of SHRP 2 project C08, Community Visioning Approach to Support the SHRP 2 Collaborative Decision-Making Framework for Additions to Highway Capacity, was to help transportation agency practitioners assess the possibilities of community visioning efforts, identify practical steps and activities when engaging in visioning, and establish links between vision outcomes and transportation planning and project development processes. To these ends, this research presents a model - the Vision Guide - or the preparation, creation, and implementation of a visioning process. A companion web tool was also developed. SHRP 2 Report S2-C08-RR-1: Linking Community Visioning and Highway Capacity Planning is available as a PDF and through the TRB bookstore. The appendices, which include case studies and a collection of resources, were published as a separate document, S2-C08-RW-2, and are available only as a PDF. The Vision Guide is connected to the transportation planning and project development processes identified in related SHRP 2 Capacity research and presented in the Decision Guide structure on the website Transportation for Communities - Advancing Projects through Partnership (TCAPP), found at transportationforcommunities.com"--Publisher's description

This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, documents the evaluation and demonstration of real-time smoothness measuring technologies on Portland Cement Concrete (PCC) pavements during construction. The research in this report will improve process control and allow for two technologies, the GOMACO Smoothness Indicator and the Ames Engineering Real Time Profiler, which were both tested in the field on actual paving projects in Arkansas, Texas, Michigan, Georgia, and New York.
