Innovation of the Month: Intersection Control Evaluation

Highway agencies use various Intersection Control Evaluation (ICE) processes and metrics to evaluate intersection geometry and control alternatives and to identify optimal geometric and control solutions for an intersection. These processes typically look at factors such as safety; operational, multimodal, and environmental considerations; right-of-way; cost impacts; and other considerations. ICE is a data-driven, performance-based framework and approach used to objectively screen intersection alternatives. Using ICE can help minimize risk of unexpected obstacles during construction while helping agencies select the best projects for implementation.

Recently, the National Academies of Sciences, Engineering, and Medicine posted Report 1087, "Guide for Intersection Control Evaluation (ICE)" through the National Cooperative Highway Research Program (NCHRP). This guide incorporates processes, objective performance metrics, and tools to help agencies provide consistent and objective ICE. In addition to the guide, the project produced nine implementation tools to facilitate States' use of the guide, including the ICE Process Tool and the Planning and Preliminary Engineering Applications Guide Tool for ICE.

A growing number of transportation agencies are developing and adopting ICE policies. Virginia, Ohio, and Colorado recently published ICE procedures and tools, bringing the number of States to adopt formalized ICE policies and procedures to 15. While there are differences among the States' policies and procedures, they are consistent in emphasizing transparency, flexibility, and adaptability. The NCHRP Guide makes it possible for agencies currently without an ICE policy or procedure to streamline development and adoption, while also using the ICE tools as starting points.

Agencies with ICE policies are realizing several benefits, including:

  • Implementation of safer, more balanced, and more cost-effective solutions.
  • Consistent documentation that improves the transparency of transportation decisions.
  • Increased awareness of innovative intersection solutions and emphasis on objective performance metrics for consistent comparisons.
  • The opportunity to consolidate and streamline existing intersection-related policies and procedures, including access or encroachment approvals, new traffic signal requests, and impact studies for development.

To learn more about ICE, visit the FHWA ICE website or contact Jeff Shaw, FHWA Office of Safety.

Ultra-Thin Bonded Wearing Course Protects Popular Massachusetts Route

Targeted pavement overlay solutions (TOPS) reduce maintenance, maximize previous investments, and lessen user delays by extending service life of pavement structures.

In 2018, the City of Newton, MA, searched for a solution to restore ride quality to a roadway section while sealing and protecting the underlying pavement. Ultra-thin bonded wearing course (UTBWC), an overlay composed of a heavy-tack application of polymer-modified emulsion, was selected for the roadway treatment. City officials considered UTBWC an environmentally and economically sustainable pavement solution. UTBWC is also known to effectively treat minor rutting and can help slow fatigue cracking.

In 2020, the city completed a trial project to preserve a section of the deteriorating concrete roadway and in 2022, used UTBWC as an overlay over hot in-place recycling. One of the major benefits of UTBWC is how quickly traffic can resume on high-volume roadways. In some instances, the time to reopen was measured in minutes rather than hours.

To learn more about UTBWC or other TOPS applications, please contact TOPS co-team leads Tim Aschenbrener, FHWA Office of Preconstruction, Construction, and Pavements (asphalt) or Robert Conway, FHWA Resource Center (concrete).

National Work Zone Awareness Week (April 15-19, 2024)

NWZAW 2024 Poster. Reads 2024 National Work Zone Awareness Week. Work Zones are temporary. Actions behind the wheel can last forever. Image depicts driver texting on mobile phone while driving through a work zone.

Work zones are critical for upgrading and maintaining our roadways, which not only provide critical access to the traveling public, but also support the Nation's economy through the transport of vital goods and services. Safety in work zones remains a significant issue: there were 891 work zone fatalities1 and 94 highway workers occupational fatalities in roadway construction sites2 in 2022. Additionally, 30 percent of fatal work zone crashes in 2022 involved large trucks or buses and many of these were rear-end collisions3. From 2021 to 2022, work zone fatalities decreased by 7.5 percent while fatal work zone crashes that involved speeding increased by 2 percent4. As a result, the Federal Highway Administration and its partners sponsor National Work Zone Awareness Week every spring to bring attention to motorist and worker safety and mobility issues in and around work zones.

Smart Work Zone technologies are one solution to help improve work zone safety. Most agencies specify the use of static warning signs indicating that trucks may enter the roadway from the work space. Unfortunately, because motorists often pass these signs repeatedly without encountering construction vehicles, they may eventually disregard the sign and fail to remain vigilant for a slow-moving vehicle potentially entering or exiting the work space. However, Smart Work Zone technologies can improve work space access point safety by dynamically warning approaching drivers about the presence of slow-moving construction vehicles entering or exiting work spaces among high-speed traffic, thereby improving work zone safety for all users. For more information, contact Martha.Kapitanov@dot.gov, Transportation Specialist, Work Zone Management Team.

Applications Open for AID Demonstration Grants

Let's Innovate! The Accelerated Innovation Deployment (AID) Demonstration program provides incentive funds to eligible entities to accelerate the implementation and adoption of innovation in highway transportation. The 2024 AID Demonstration solicitation for FY2024 is open and the Federal Highway Administration (FHWA) plans to award up to $12.5 million in grants. Visit the AID Demonstration projects webpage to learn about the 127 grants and more than $95.7 million dollars that FHWA has awarded since the program's launch in 2014.

AID Demonstration funds are distributed through a competitive discretionary grant process. The required Notice of Intent must be submitted to Grants.gov on or before April 16, 2024, with an application deadline of May 28, 2024. Details on this funding opportunity are available on the AID Demonstration webpage and on Grants.gov (funding opportunity number 693JJ324NF-AIDDP).
