|5/1/2022||UAS||When 9,500 linear feet of historic rock guard wall at Crater Lake National Park in Oregon had to be inventoried in 2020, the FHWA Western Federal Lands Highway Division (WFLHD) relied on UAS to document the boundaries of the stonework along East Rim Drive, a scenic highway on the lake's rim. The report would help with rehabilitation and rockfall mitigation at one of the park's most unique and beautiful historic features.
Choosing UAS over traditional methods, the agency avoided the human risk and costs involved with hanging a camera from a crane near the edge of the scenic overlook or hiring a helicopter to collect the images at a dangerously close proximity to the wall.
"UAS was really the clear winner in terms of efficiency, cost, and data quality," said Zekial Rios, land services manager at WFLHD.
Rios referenced the inventory previously done on the park's historic stone wall on West Rim Drive. It took about seven people to do the crane work and the entire summer.*
"With UAS, we did it with three people in about 3 weeks," Rios said.
Also, using UAS significantly reduced the noise disturbance for visitors and wildlife compared with using a helicopter to capture the data.
"If you're in one of the most scenic national parks in the country, and you're feeling the wind and looking at this deep blue water but you're hearing helicopters rolling overhead—that's really going to ruin somebody's experience," Rios said.
All-in-all, UAS helped WFLHD get "the best look at the walls since they were constructed in the 1940s," Rios said.

TSD-based structural condition data can be incorporated into pavement management systems at the network level. Compared to traditional methods that require lane closures, TSD provides faster, safer data collection and processing.

|4/8/21||STIC||Are you interested in homegrown innovations being used by your peers in other parts of the country? Check out the National STIC Network Showcase, a component of the EDC-6 Virtual Summit. Over 200 innovations, submitted by State DOTs, Local Agencies, and other STIC members, are grouped into eight topic area categories for easy navigation. This site features a convenient one-time registration that will allow you to continue accessing information throughout 2021.
The showcase prominently features several innovations focused on bridge preservation and repair. Learn about the El Paso County, CO, Adaptable Bridge Safety Platform, a unique alternative fall protection solution for bridge deck replacements in areas with unstable soils and limited scaffolding space, but that aren’t high enough to require worker catch systems; Indiana DOT's Bridge Deck Preservation using Epoxy Injections, which prevents fluid intrusion and slows down freeze/thaw deterioration; Minnesota DOT's Affordable Bridge Beam End Repair, which used concrete to reinforce beams in need of repair; and Federal Lands Highway's Fiber-Reinforced Polymer Deck Panels, which were used to rehabilitate the 532-foot Fishing Bridge in Yellowstone National Park.
Celebrate the ingenuity of your peers and read about these innovations–developed and deployed in-house at transportation agencies nationwide. Additionally, we invite you to watch the one-hour presentations on-demand that feature many of these and other innovations.

In 2019 a steady increase of visitors to national parks and other Federal Lands resulted in an increased risk of pedestrian-vehicle crashes.|
To address this issue, the FHWA FLH Safety Team and Federal Land Management Agency (FLMA) safety specialists collaborated to develop an action plan to guide decisions for enhancing visitor and pedestrian safety. Representatives from the National Park Service, US Forest Service, Bureau of Land Management, and US Fish and Wildlife Service, worked with the Safe Transportation for Every Pedestrian (STEP) program to review existing policies and identify preliminary strategies to improve pedestrian safety.
The approved plan calls for FLMAs to collect and map pedestrian crashes to identify high crash locations and conduct systemic crash analyses to prioritize locations for safety countermeasures based on factors other than historic crash data. These and other strategies such as pedestrian safety training will be incorporated into long-range transportation plans and projects designed and constructed by FLH, FLMA, and other partner agencies to reduce pedestrian injuries and fatalities on Federal Lands.

To determine the best approach to reconstructing the damaged road, Federal Lands Highway (FLH) used two-dimensional (2D) hydraulic modeling, a strategy promoted in the EDC-4 initiative on collaborative hydraulics: advancing to the next generation of engineering (CHANGE). Applying 2D modeling enabled the FLH team to develop a cost-effective design to increase the sustainability of the road by realigning it away from the flood channel and redirecting the channel where necessary to provide water to a wetlands area.|

The project involved applying a microseal—a thin, durable coating that helps prevent future cracking—to the surface of the main road and parking areas. The treatment is expected to extend the life of the road, which provides access to numerous recreational areas throughout the park. For information, contact James Kerrigan of CFL.|
A transportation improvement project in the Bureau of Land Management’s (BLM) Red Rock Canyon National Conservation Area in Clark County, NV, includes road rehabilitation, two bridges, and parking area expansions. Using the concept of improving collaboration and quality environmental documentation, BLM, CFL, and environmental consultants collaborated on a streamlined review process in the design, National Environmental Protection Act, and permitting portions of the project. The conservation area’s core values, including protecting natural resources while providing an excellent visitor experience, were preserved while maintaining an accelerated project delivery schedule. The Safety Edge paving technique was used on 13 miles of roads to bevel the pavement edge to reduce roadway departure crashes.
