ADVANCED RESEARCH

FHWA Supports NSF’s Cyber-Physical Systems 

Program

The National Science Foundation (NSF) recently 

released a solicitation for a unique opportunity 

for investigators to support its Cyber-Physical 

Systems Program. Cyber-physical systems (CPS) 

are engineered systems built from and 

dependent on the seamless integration of 

computational algorithms and physical 

components. As FHWA has an interest in 

research and development that provides 

improved safety, mobility, and energy 

conservation in the development and operation 

of the highway system, it is working closely with 

NSF and other Federal agencies on CPS. In the 

context of highway transportation, CPS must be 

scalable, reliable, adaptable, and secure while 

also being cost-effective. 

In particular, FHWA is interested in fundamental 

research aimed at solving important public 

needs. It also seeks research that can scale 

across transportation systems, modes, and into 

other domains. Approaches should consider the 

open nature of the transportation system, 

legacy components and processes, and the 

distributed nature of asset ownership and 

operations. FHWA encourages utilization of 

existing test beds, pilot deployments, and real 

world data. The CPS Program solicitation (16-

549) will be soon available on NSF’s Web site.

EAR Program Demos New Assistive 

Technologies for the Visually Impaired 

FHWA’s EAR Program is sponsoring research 

focused on adapting sensor and guidance 

technology found on luxury passenger vehicles

for use by blind and vision impaired pedestrians. 

On March 3, 2016, the EAR Program 

demonstrated the Intelligent Situation 

Awareness and Navigation Aid (ISANA) at USDOT

headquarters in Washington, DC. Researchers 

equipped Barbara Campbell, a visually-impaired 

test subject, with ISANA’s tablet-based, 

wearable technology. 

Using ISANA, and with additional assistance, she 

successfully navigated USDOT headquarters, 

moving from the main security entrance in the 

West Building to the eighth floor of the East 

Building. Since GPS is not available to indoor 

receivers, a fish eye lens and custom software 

on the tablet interpreted the visual environment 

for her in real time and provided Barbara with 

voice guidance to help her navigate potential 

obstacles and provide situational awareness of 

her surroundings.

Funded through the EAR Program, and 

conducted in coordination with the John A. 

Volpe National Transportation Systems Center 

(Volpe), the Federal Transit Administration, and 

the Intelligent Transportation Systems Joint 

Program Office (ITS-JPO), the multiyear project 

is focused on developing technology that 

provides guidance assistance to blind and 

visually-impaired pedestrians navigating in large, 

unstructured environments. The new 

technology is in the earliest stages of research 

and is still many years away from being marketready.

Report Available on Truck Following Behavior

Volpe conducted research that is described in a 

recent report titled, “Naturalistic Study of Truck 

Following Behavior.” The goal of the study was 

to support FHWA’s Office of Research, 

Development, and Technology in developing 

automated applications for truck platooning. 

Grouping vehicles into platoons (a series of 

vehicles traveling together with short following 

distances) is a method of safely increasing road 

capacity by using automation technologies and 

electronic coupling to decrease distances 

between vehicles. Using two naturalistic heavytruck data sets collected from previous research, 

Volpe quantified heavy truck following behavior 

in the following categories: how closely trucks 

follow other trucks and passenger cars on 

freeways; how following behavior varies by road 

weather and visibility; following distances at 

which other vehicles will cut-in between a truck 

and a lead vehicle; and the safety impact of 

different headways.

SAFETY

Data Collection for Motorcycle Crash Causation 

Study Complete

FHWA has completed data collection for a 

Motorcycle Crash Causation Study (MCCS), 

which includes 351 usable cases and 702 control 

rider interviews. Authorized under the Safe, 

Accountable, Flexible, Efficient Transportation 

Equity Act: A Legacy for Users (SAFETEA-LU), the 

study is focused on assembling data that can be 

used to investigate causes of motorcycle crashes 

in the United States. Data for the MCCS, which is 

the largest study of its kind in 30 years, was 

collected from June 2011 to January 2016. 

Through a cooperative agreement with 

Oklahoma State University and in coordination 

with National Highway Traffic Safety 

Administration (NHTSA) and other research 

partners, a team of field investigators conducted 

in-depth investigations into motorcycle crashes 

in Orange County, California. Collected data 

elements include information on the motorcycle 

type, rider demographics, roadway 

characteristics, traffic details, alcohol use, rider 

behaviors, and other factors related to the crash 

event. Crash investigations include onsite 

physical investigations, onsite interviews with 

crash participants, follow up vehicle inspections, 

follow up interviews, and injury data collection. 

Police jurisdictions in Orange County, California 

played a vital role in the success of this effort.

The resulting motorcycle crash causation 

database is expected to serve as a foundation 

for motorcycle safety research for years to 

come. Funding partners for the MCCS include 

FHWA, NHTSA, and the American Motorcyclist 

Association. Participating State departments of 

transportation (DOTs), include the Iowa DOT, 

New Mexico DOT, New York State DOT, Ohio 

DOT, Oklahoma DOT, Texas DOT, and Wisconsin 

DOT. 

The research team is now working to finalize the 

database and supporting documentation. FHWA 

anticipates that highway safety researchers will 

have access to all of data through the Highway 

Safety Information System Web site sometime 

in 2016.
