This report develops and verifies material and structural models for asphalt mixture performance-related specifications (AM-PRS). The models the research team developed and verified in this study include the simplified viscoelastic continuum damage (S-VECD) model for fatigue cracking, the shift model as a permanent deformation model, the healing model based on...

This report is part of the Human Factors for Connected Vehicles (HFCV) program, whose goal is to minimize driver workload by eliminating connected vehicle (CV) device-related distractions. The research described in this document is part of an effort to develop initial design considerations for vehicle-to-pedestrian (V2P) safety messages provided to drivers via...

Limited transport options in rural and remote areas hinder access to basic services, jobs and social activities. This report presents international best practices and recommendations for transport provision in communities where conventional public transport is difficult to sustain. It examines how sustainable accessibility for people without access to a car...

During the winter season, snowmobile riders in many jurisdictions use trails that are usually managed and maintained by snowmobile clubs and associations. The problem lies when these trails intersect with vehicular highways or paved park trails owned and maintained by a public agency. A single crossing can see thousands of snowmobiles in a single season, which...

Public agencies benefit from measuring their performance as it helps to focus employee and organizational activities. State departments of transportation have become more performance-oriented over the past two decades and routinely collect data on highway safety, infrastructure condition, system operations, project delivery, winter maintenance, transit, bicycle...

Traffic speed deflection devices (TSDDs) are designed to measure pavement deflections or deflection velocities in response to loads applied by trucks moving at or near prevailing traffic speeds. TRB's Transportation Research Circular E-C276: State Departments of Transportation Experiences and Applications with Traffic Speed Deflection Devices details a...

The ultimate objective of this project was to determine the structural performance of the dynamic message sign (DMS) bonded with chemical adhesive in terms of ultimate strength and fatigue strength. To achieve this objective, this project first investigated the effects of various parameters (i.e., conditioning humidity and conditioning temperature) on tensile,...

This project investigated the influence of intersection corner radius on pedestrian crashes and right-turn vehicle speed. The corner radius can be unique to each corner at an intersection; therefore, this study assigned crashes to an intersection corner rather than to the entire intersection. For corner-level pedestrian crashes, the following variables were...

During the last 20 years, the Federal Aviation Administration made significant efforts to develop one of the most comprehensive specifications to prevent alkali-silica reaction (ASR) in new construction [see the Advisory Circular (AC) 150/5370-10H, Item P-501]. The AC was effective, to a large extent, in preventing ASR in new airport pavements during the last...

The Federal Highway Administration (FHWA) Roadway Safety Data Program is working with State and local agencies to develop case studies around roadway safety data collection, management, and analysis issues. These case studies help illuminate both the challenges that agencies encounter on data issues and the solutions they are implementing to address those...
