GENERAL/ADMINISTRATIVE

NTSB Chair Visits Turner-Fairbank 

On June 4, 2015, Chris Hart, Chairman of the National Transportation Safety Board (NTSB), and 

several managers and technical staff from NTSB visited FHWA’s Turner-Fairbank Highway Research 

Center (TFHRC). Chairman Hart was primarily interested in visiting laboratories at TFHRC that have 

assisted NTSB in its investigations or are associated with the Board’s priority agenda.

These laboratories include: 

• The Structures Lab, which supported NTSB after the I-35W Bridge collapse and the Big Dig Tunnel 

roof panel collapse.

• The Human Factors Lab—specifically, the Highway Driving Simulator to investigate driver 

reactions to highway design and operations features.

• The Saxton Transportation Operations Lab—primarily research related to the Connected Vehicle 

Program, especially vehicle-to-infrastructure and vehicle-to-pedestrian connectivity.

• The Federal Outdoor Impact Lab—specifically, to see how computer models to simulate vehicle 

to roadside hardware crashes are created and validated through live crash tests. This laboratory 

has also worked with the Department of State on design and testing of anti-ram barriers for U.S. 

embassies.

ADVANCED RESEARCH

EAR Publishes RAP Catalog

FHWA’s Exploratory Advanced Research (EAR) 

Program, which addresses the need for longerterm, higher-risk research with potential for 

long-term improvements to transportation 

systems, has just published the first edition of 

its Research Associate Program catalog. FHWA 

has participated in the National Research 

Council Research Associateship Program (RAP) 

since 1992. To supplement the expertise of 

permanent staff, TFHRC, through the EAR 

Program, invites researchers with appropriate 

backgrounds to investigate specific problems on 

a short-term basis across a wide range of topics 

and disciplines. 

RAP provides opportunities for the EAR Program 

to advance research methods used at TFHRC in 

such areas as nano-additives for concrete and 

asphalt, alternative intersection and interchange 

design, and modeling to predict collisions based 

on driver behavior and environmental 

conditions. The catalog, “Exploratory Advanced 

Research Program Research Associates Program 

2014,” provides a summary of some of the 

research projects that resident fellows have 

been involved in during their tenures at FHWA.

The document is available at 

www.fhwa.dot.gov/advancedresearch/pubs/15

031/index.cfm. For more information about the 

EAR Program, contact David Kuehn, 202-493-

3414, david.kuehn@dot.gov. 

Video Analytics Opens the Way to Managing 

Large Data Files 

The EAR Program has just published a catalog

consolidating 3 years of its video analytics 

research to make data processing and analysis 

more practical by focusing on increasing the 

automation of video data decoding. The 

Transportation Research Board’s Second 

Strategic Highway Research Program (SHRP2) 

study demonstrates the immense scale of data 

being gathered. The flagship dataset to emerge 

from the SHRP2 Program is the naturalistic 

driving study, which includes over a million 

hours of video data from inside and outside 

regular passenger vehicles in normal day-to-day 

use. The study is designed to improve 

understanding of the interaction of various 

factors involved in highway crashes—driver, 

vehicle, and infrastructure—so that better 

safety countermeasures can be developed and 

applied to save lives.

Students at TFHRC’s Transportation Summer MiniCamp 
 FHWA R&T Now

The goal of these EAR Program projects is to 

assist researchers through the use of an 

algorithm designed to narrow down the 

amount of data researchers need to manually 

review. This will enable researchers to quickly 

and accurately extract the required details 

from large data files. There are six ongoing 

video analytics projects funded by the EAR 

Program, all tasked with developing 

technology to make it feasible for researchers 

to quickly and flexibly get what they need 

from an extremely large dataset. 

The catalog covers the initial research on 

machine learning that was awarded to Carnegie 

Mellon University (CMU) in 2012; three 

additional research projects awarded to SRI 

International, CMU, and the University of 

Wisconsin-Madison in 2014 on lessons learned 

from the initial research; two additional 

research awards to CMU and SRI International 

to investigate automated identity masking; and 

a benchmarking research progress project 

awarded to the Department of Energy’s Oak 

Ridge National Laboratory to develop tools for 

benchmarking research progress. 

Transportation researchers are starting to use 

extremely large datasets to identify and 

understand complex transportation issues that 

can impact transportation efficiency, cost, and 

safety. New automated tools for data extraction 

and analysis will help make these massive 

datasets accessible to the widest possible range 

of researchers, dramatically reducing the cost 

and time it takes to process raw data.

The catalog is available at 

www.fhwa.dot.gov/advancedresearch/pubs/15

025/index.cfm. For more information about the 

EAR Program, contact David Kuehn, 202-493-

3414, david.kuehn@dot.gov. 

Reference Scan on Behavioral Economics and 

Transportation Available on EAR Web site

An initial stage reference focused on behavioral 

economics and transportation safety is available 

on the EAR Program’s Web site: 

www.fhwa.dot.gov/advancedresearch/pubs/15

035/index.cfm. The scan identifies published 

literature between 2012 and 2013. This

investigation is a first step in the EAR Program 

process for exploring ideas across traditional 

and nontraditional fields of research and 

stimulating new approaches to problem solving. 

The literature review and reference scan allows 

for a better understanding of active research in 

a particular topic area. The scan also contributes 

to the process of identifying priorities and 

opportunities for strategic investment in further 

research. The EAR Program reference librarian 

uses various selection criteria, such as authority, 

relevance, and timelines, and scans information 

that has not been published, such as 

presentations, papers, and grant awards. Each 

year the EAR Program explores 20 or more 

topics.

INFRASTRUCTURE

Pavement Materials Team Hosts Meeting for 

TPF Project

On June 2, 2015, FHWA’s Pavement Materials 

Team in the Office of Infrastructure Research 

and Development (R&D) hosted a meeting at 

TFHRC to discuss the transportation pooled fund 

(TPF) project, “Standardizing Lightweight 

Deflectometer Measurements for Quality 

Assurance and Modulus Determination in 

Unbound Bases and Subgrades.” The meeting 

Hands on steering wheel segmentation
 FHWA R&T Now

brought together TPF representatives from 

departments of transportation in Indiana, 

Maryland, Michigan, Minnesota, New York, 

South Carolina, and Virginia, as well as 

professionals from FHWA’s DelMar Division and 

Baltimore Resource Center, Kessler Soils 

Engineering Products, Inc., and the University of 

Maryland. The main purpose of the meeting was 

to coordinate research that will be conducted at 

the large-scale outdoor laboratory at TFHRC’s 

Pavement Test Facility. Attendees toured the 

pavement and geotechnical laboratories.

The goal of the research is to develop stiffnessbased technologies for quality control and 

acceptance of highway materials during 

construction of embankments, asphalt, and 

pavement base or subgrade layers 

specifications. Current practice for compaction 

control involves using the nuclear density gage. 

However, these devices have a significant time 

and cost overhead for upkeep, security, and 

training for both agencies and contractors. The 

profession has been moving away from 

conventional density-based construction and 

placing more focus on implementing modulus or 

stiffness-based construction because these 

more fundamental engineering properties have 

a more direct influence on pavement design and 

performance. 

The TPF project seeks to replace nuclear density 

gauges with portable lightweight deflectometer 

instruments that measure stiffness and modulus 

directly. There is currently no widely recognized 

standard for interpreting the load and deflection 

data obtained during construction quality 

assurance testing and relating these 

measurements to the elastic modulus values 

used in pavement design. This research is 

expected to provide a straightforward 

procedure that can be employed by inspection 

personnel. 

For more information, contact Charles Schwartz, 

the principal investigator for the project, at 301-

405-1962 or schwartz@umd.edu. 

FHWA Brings New Safety Technology to the 

United States

Higher friction can help a vehicle stop or 

maneuver its way out of a crash. In a project 

funded by FHWA, the first Sideway-force 

Coefficient Routine Investigation Machine 

(SCRIM) in the United States will assist States in 

using the American Association of State 

Highway and Transportation Officials (AASHTO) 

Pavement Friction Management Guide. The 

instrumentation is housed in an orange Volvo 

truck owned by FHWA.

The truck will be driven thousands of miles 

through Florida, Indiana, Texas, and Washington 

collecting data. FHWA awarded the Virginia 

Tech Transportation Institute (VTTI) a contract 

to use the SCRIM to continuously measure 

friction, cross-slope, macro-texture, grade, 

temperature, and curvature while being driven 

up to 50 miles per hour in these four States. The 

FHWA’s Pavement Materials Team hosted a meeting to 

discuss a transportation pooled fund project.

FHWA’s orange Sideway-force Coefficient Routine 

Investigation Machine
 FHWA R&T Now

vehicle, which arrived in the United States at the 

end of May 2015, is being testing on VTTI’s 

Smart Road. 

Various measurements will be cross-referenced 

with crash data for developing pavement 

friction management programs. This data is 

expected to advance development of friction 

demand categories and set thresholds to 

identify road segments to investigate for 

remedial measures before crashes occur. The 

current practice of most States is to use a locked 

wheel skid trailer that spot checks about every 

500 feet.

OGA Research to Advance Higher Friction 

Angles for Structural Backfills

FHWA recently published the report, “Strength 

Characterization of Open-Graded Aggregates for 

Structural Backfills” (FHWA-HRT-15-034), which 

discusses a study focused on establishing a 

knowledge base of the most commonly used 

American Association of State Highway and 

Transportation Officials (AASHTO) open-graded 

aggregates (OGA).

State and local transportation agencies 

frequently use crushed, manufactured opengraded aggregates as structural backfill material 

for retaining walls, bridge foundations, and 

other ground improvement applications, yet 

their strength characteristics are not fully 

understood or applied. To address this gap, 

researchers began a study at TFHRC that 

included a systematic approach to fully 

characterize the strength parameters utilizing 

the large scale direct shear and triaxial devices 

in the Geotechnical Laboratory. Researchers 

also investigated relationships between other 

important soil parameters on the friction angle, 

as well as the impact of different automated 

testing devices and data interpretation 

methods. 

This report presents the results of this research 

and is expected to assist State and local 

transportation agencies, researchers, and design 

consultants in gaining confidence on the use of 

higher friction angles for structural backfills to 

optimize the design of geotechnical features.

GRS-IBS Guidance Helps Ohkay Owingeh 

Pueblo Construct Bridge 

Thanks to FHWA’s guidance, the Ohkay Owingeh 

Pueblo in New Mexico can now construct 

bridges using the Geosynthetic Reinforced Soil 

Integrated Bridge System (GRS-IBS), an 

innovation supported by FHWA under Every Day 

Counts (EDC), the agency’s partnership with 

States and localities to encourage the use of 

technologies, approaches, and project delivery 

methods that save time, save money, and save 

lives. Assisted by Tribal Transportation Program 

funds and a $200,000 Accelerated Innovation 

Deployment Demonstration grant, the pueblo is 

putting its own people to work to replace a 60-

foot bridge. To prepare for the Every Day Counts 

deployment, they worked with the Office of 

Federal Lands, studied FHWA GRS-IBS guidance, 

and attended the Kaw Nation/Kay County GRSIBS Showcase in Blackwell, OK last year. 

Equipped with newly learned construction skills, 

the pueblo is now at the cutting edge of 

technology for replacing small structures across 

its land.

SAFETY

ELCSI Pooled Fund Study Holds Eleventh 

Annual Meeting

On June 2 and 3, 2015, representatives of 38 

State departments of transportation 

participated in the Eleventh Annual Technical 

Advisory Committee (TAC) meeting for the 

Evaluation of Low Cost Safety Improvements 

Pooled Fund Study (ELCSI-PFS) at TFHRC. The 

objective of the meeting was for State 

representative members to receive progress 

updates for ongoing phases of the study, learn

about other current and upcoming safety efforts 

at State and Federal levels, exchange 

information and ideas with peers, conduct 

technology transfer, and cast ballots identifying 

high priority safety strategies for future studies.

Since its inception in 2005, this pooled fund 

study has evaluated the safety effectiveness of 

more than 45 of the low-cost safety 

improvements listed as priority strategies in the 

National Cooperative Highway Research 

Program Report 500 Guides. Crash Modification 

Factors (CMFs) for each evaluation are 

developed and will be posted at the CMF 

Clearinghouse, administered by FHWA’s Office 

of Safety and Highway Safety Manual. Research 

is currently underway to evaluate an additional 

18 low-cost safety improvements, including 

pedestrian countdown signals and a 

combination of median barrier and rumble 

strips. Membership in this pooled fund study 

has steadily grown and funding has increased 

from $2.8 million to $3.6 million in State 

commitments and from $1.5 million to $2.5 

million in FHWA contributions.

Report Documents Factors Affecting Speed and 

Safety, Describes Treatments

FHWA recently published the report, “Factors 

Influencing Operating Speeds and Safety on 

Rural and Suburban Roads” (FHWA-HRT-15-

030), which documents component factors 

affecting speed and safety on rural and 

suburban roadways that are not limited access 

and describes treatments that have the 

potential to reduce speed-related crashes. 

Drivers who exceed the speed limit or drive too 

fast for the conditions are involved in nearly 

one-third of all fatal crashes. Over 13,000 

people are killed in speeding-related crashes 

each year. The first phase of the study included 

a review of literature on design features and 

current practices associated with safer 

operating speeds and identification of 

treatments for field evaluations. The second 

phase involved evaluating treatments to 

determine their effectiveness in reducing speeds 

on two-lane horizontal curves in rural and 

suburban areas.

OPERATIONS

Saxton Lab Demonstrates Nation’s First 

Automated Eco-Friendly Cruise Control

Together with its partners, FHWA’s Saxton 

Transportation Operations Laboratory has 

TAC meeting for the Evaluation of Low Cost Safety 

Improvements Pooled Fund Study
 FHWA R&T Now

implemented and successfully demonstrated 

the Nation’s first application of a cooperative 

adaptive cruise control that automatically 

communicates wirelessly with a traffic signal 

and controls a vehicle’s approaching and 

departing speed in an eco-friendly manner. The 

technology can potentially save approximately 

20 percent in fuel. The Saxton Transportation 

Operations Laboratory successfully outfitted a 

Ford Escape hybrid vehicle with a robotic speed 

controller, an onboard computer, high-precision 

location equipment (an augmented global 

position system), and a dedicated short range 

communication (DSRC) unit. FHWA Office of 

Operations R&D staff, in cooperation with 

partners, built onboard application and control 

software that provides a tablet-based driver 

interface and computes an optimum speed 

trajectory through TFHRC’s intelligent 

intersection. Upon computing this trajectory 

and activation by the driver, the software takes 

control of the vehicle’s accelerator and brakes 

to safely and smoothly drive it through the 

intersection while respecting the traffic signal 

and local speed limit. Just as with any cruise 

control, the human driver is always in control of 

the vehicle and can disengage the automation 

by stepping on the brake or turning the cruise 

control feature off. 

FHWA’s pioneering work has established a solid 

foundation for continued research and 

invention involving variable signal timing, 

accommodating other vehicles in the 

intersection, and investigating multisignal 

applications. This work is part of FHWA’s Office 

of Operations R&D’s mission and is jointly 

funded by FHWA’s EAR Program, Office of 

Operations, and the Intelligent Transportation 

Systems (ITS) Joint Program Office’s Program: 

Applications for the Environment: Real-time 

Information Systems. This project will also 

continue through the Crash Avoidance Metrics 

Partnership, a consortium of 12 vehicle 

manufacturers who will first further investigate 

the feasibility of this application and then 

conduct a small scale prototype/test for possible 

commercial deployment in the future.

Web Portals Demonstrated at USDOT Data 

Palooza

On June 16 and 17, 2015, the Intelligent 

Transportation Systems (ITS) Joint Program 

Office, FHWA’s Office of Operations, and 

FHWA’s Office of Operations R&D demonstrated 

ITS related applications and data available to 

use on the Open Source Application 

Development Portal (OSADP) and Research Data 

Exchange (RDE). The demonstrations highlighted 

the software, computer code, and data available 

to use when conducting research, developing, 

testing, evaluating, and planning for applications 

that may include connected vehicle, mobile 

devices, travelers, and weather conditions. 

The OSADP and RDE are Web portals that 

enable usage of open source software, 

computer code, and data for deployment-ready 

ITS related applications. Users can also 

collaborate on the development of the 

software, computer code, and data. A high-level 

overview of the ITS Data Capture Management 

Program and its six program tracks was provided 

during the Data Palooza. Team members 

displayed and discussed the evaluation 

approach, current status (including RDE 

analytics graphs and charts), and elements from 

the executive dashboard.

University Researchers Spending Summer On 

Lane Change/Merge Weave Project

Saxton lab is hosting a team of researchers this 

summer from Auburn University, Ohio State 

University, and the University of California, 

Riverside. The researchers are participating in 

foundational research on lane change/merge 

maneuvering in vehicles with automated 

longitudinal control. The objective of this 

project is to obtain a basic, experimental 

understanding of the needs and methodologies 
 FHWA R&T Now

for performing automated lane change/merge 

maneuvers. The research team, with FHWA 

guidance, is developing a “Vehicle Maneuvering 

Ideas/Concepts Matrix,” in which they define 

concepts for lane change/merge (i.e., scenarios, 

use cases, etc.); develop hypotheses for each 

concept; determine the hardware, software, 

and data needs for each concept; and evaluate 

the concept by quantifying its impacts on traffic 

throughput, safety, and fuel consumption. As a 

demonstration of collaboration and knowledge 

of the field, the faculty and students from the 

three universities have jointly coauthored and 

submitted a survey article on these topics for 

peer review and publication in the Institute of 

Electrical and Electronics Engineers’ 

Transactions on Intelligent Transportation 

Systems. In addition, the team is developing and 

simulating algorithms for lane change/merge. 

These algorithms will be implemented and 

tested on two of FHWA’s research vehicles at 

TFHRC.
