USDOT Combats Human Trafficking

In January, U.S. Transportation Secretary Elaine L. Chao called on transportation leaders to help "put the brakes on human trafficking" and announced $5.4 million in grants awarded through the Federal Transit Administration's Human Trafficking Awareness and Public Safety Initiative.

Secretary Chao says that USDOT "is committed to working with our public and private partners to fight human trafficking on America's transportation system." More than 440 organizations have signed on to the Secretary's "Transportation Leaders Against Human Trafficking" pledge.

A number of USDOT initiatives are underway to increase awareness of human trafficking and equip transportation industry employees and the public with strategies to fight it. More than 53,000 USDOT employees receive mandatory counter-trafficking training, including special instruction for bus and truck inspectors. The Department also works with Federal agencies and nongovernmental organizations to develop and distribute a suite of human trafficking awareness training tailored for the aviation, rail, motor coach, trucking, and transit industries.

Secretary Chao Announces New Safety Initiatives

At the Transportation Research Board (TRB) Annual Meeting in January, Secretary Chao announced transportation initiatives aimed at harnessing new and existing technologies to improve safety for the traveling public and first responders.

USDOT is beginning the next phase of the Partnership for Analytics Research in Traffic Safety (PARTS) program. PARTS II expands participation in the PARTS program to include almost 70 percent of the U.S. automobile market and will collect data on additional advanced driver-assistance systems, such as adaptive cruise control and lane keep assist. Results derived from analysis of up-to-date, real-world performance data will assist researchers in assessing the safety effectiveness of these systems. PARTS is a voluntary, data-driven safety partnership between USDOT's National Highway Traffic Safety Administration and the automobile industry.

Secretary Chao also announced a new program designed to help avoid traffic accidents and save the lives of first responders rushing to aid in emergencies. The Department intends to invest up to $38 million for the First Responder Safety Technology Pilot Program that will help equip emergency response vehicles and key infrastructure with vehicle-to-everything (V2X) communication technology. These systems will use the 5.9 GHz Safety Band of spectrum currently allocated by the Federal Communications Commission for use in transportation systems.

Finally, the Department is endorsing a standardized listing of terminology for recommended advanced driver-assistance systems through an initiative entitled Clearing the Confusion, spearheaded by the National Safety Council, American Automobile Association, Consumer Reports, and J.D. Power. Currently, there is variance among manufacturers. Standard language will ensure drivers are aware that these systems are designed to assist, not replace, an engaged driver.

Interactive Map Aims to Encourage Investment in Underserved Communities

USDOT recently released a new interactive map highlighting Federal investment in major projects located in and around Opportunity Zones across the country. Opportunity Zones are economically distressed communities designated by the United States Secretary of the Treasury to incentivize economic investment in these areas. The designation was created by the 2017 Tax Cut and Jobs Act.

The map provides detailed information about vital infrastructure resources located near Opportunity Zones to help determine the range of potential economic investments. It illustrates data sets for major Federal highway projects, interstate exits, National Highway System bridges, intercity bus stations, commuter and light rail stations, Amtrak, intermodal rail and marine facilities, major ports, airports, and more.

PBIC Releases New Micromobility Resources

Two new resources from the Pedestrian and Bicycle Information Center (PBIC) offer contextual and applied insight into micromobility, including e-scooters.

The Basics of Micromobility and Related Motorized Devices for Personal Transport provides an overview of powered forms of micromobility and compares features of micromobility with a spectrum of other traditional and emerging forms of transportation. With a surge of new personal transportation devices coming to the market, some integrated into shared ride systems (such as bikeshare programs), there is a need to establish a common vocabulary for these options and provide basic information about how these devices are classified and regulated. The publication is available at

The second resource, E-Scooter Management in Midsized Cities in the United States, documents practices related to micromobility, specifically e-scooters, in nine midsized U.S. cities. The scan includes feedback from city staff about challenges and opportunities that emerged with e-scooter adoption, including permitting and regulatory issues, potential safety concerns, and infrastructure design observations. It documents anecdotal evidence and noteworthy practices, and also identifies issues for future discussion. The publication is available at

Volpe Center Helps Preserve Natural Sounds in National Parks

Natural sounds are a vital part of a park visitor's experience. Whether it is the sound of an owl hooting, a stream running through a historical site, or wind blowing through vegetation, these sounds are a quintessential part of the visitor experience. USDOT's Volpe Center supports the Natural Sounds and Night Skies Division (NSNSD) of the National Park Service in its work to protect, maintain, and restore acoustical environments throughout the National Park System.

Traffic is one of the most common sources of noise that detracts from the natural soundscape. The National Park Service maintains approximately 5,500 miles (8,850 kilometers) of paved roads and 7,000 miles (11,300 kilometers) of unpaved roads. The traditional noise mitigation technique of building noise walls is not practical in the parks due to the long stretches of roadways that must be protected as well as disruption of views and animal movements. Quieter pavements provide a good alternative to noise barriers since they do not disrupt views or inhibit animal movement on already established roads. The challenges of quieter pavements include performance changes over time coupled with lifespan requirements that can be unique to national parks.

The Volpe Center is supporting NSNSD in conducting a pilot study of common pavement resurfacing treatments in Death Valley National Park to determine which may provide the most benefit in terms of noise reduction over time. The study involves measuring the noise levels before and after applying four different surface treatments. Measurements a month after the treatments have been applied show a difference in noise levels of almost 3 decibels between the treatments, the equivalent of nearly a 50-percent reduction in traffic volume. The study is planned to span 5 years, and researchers currently are preparing to measure the performance of the pavements after the third year.


The Volpe team collected roadside pavement noise data as part of the study for the National Park Service.


The Volpe team used vehicle-mounted equipment as well as roadside equipment to study pavement noise in National Parks.

Rhode Island Launches DUI Initiative

The Rhode Island Department of Transportation (RIDOT), Rhode Island State Police, and the Rhode Island Attorney General Office recently announced the creation of a new task force dedicated to reducing the number of tragedies associated with impaired driving. Despite recent strides in reducing deaths related to alcohol-impaired driving, Rhode Island is in the top third of States with the highest percentage of fatalities involving impaired drivers. In 2017 and 2018 combined, more than 50 people were killed by impaired driving on Rhode Island roads.

This new unit of the Rhode Island State Police, which began its work in mid-November, consists of a significantly increased overnight road presence. All State Police members assigned to the unit have been trained and certified in impaired driving detection techniques, including standard field sobriety tests, breathalyzer operation, and drug recognition. In the first month of operation, the unit completed 97 shifts, arrested 90 people—49 of them for driving under the influence—and issued 684 citations. In addition, responders investigated 56 crashes, with nearly 30 percent of them involving a suspected impaired driver.

Though RIDOT has traditionally provided funds to State and local police for specific enforcement periods, typically around holidays and busy travel periods, this marks the first time Rhode Island will have a year-round unit of troopers dedicated to enhancing public safety by enforcing impaired driving laws.

Unmanned Boats Help with Michigan Bridge Inspections

When the water level in local rivers and streams rises during storm events, it can create concerns about the impact on highway bridges. Inspectors need real-time data on what's happening beneath the turbulent surge, but getting into the water for a visual inspection is risky.

To address this safety concern, the Michigan Department of Transportation (MDOT) has been evaluating small remote-controlled boats for safer and more efficient bridge inspections. Scour, the erosion or degradation of the streambed around a bridge's substructure, is a leading cause of bridge failure. MDOT routinely inspects bridges for scour around abutments and piers. Typically, this involves inspectors launching a boat and probing the channel bottom with metal rods, weighted tape measures, or sonar devices. During high-flow events, this can be a dangerous task.

MDOT is strategically placing four unmanned surface vessels equipped with sonar units throughout the State to inspect bridges for scour during high-flow events. In addition, the agency plans to use the technology for other applications as appropriate, including getting images of bridge substructure below water, viewing the underside of bridges, and documenting performance characteristics.
