Utah DOT Deploys LiDAR to Boost Intersection Safety

The Utah Department of Transportation is using Light Detection and Ranging or LiDAR technology as a design tool to improve safety at intersections, specifically for pedestrians and bicyclists.

LiDAR is a remote sensing system that uses light in the form of a pulsed laser to measure variable distances to generate precise three-dimensional or 3D information. In Utah DOT’s case, traffic engineers are using LiDAR to recreate an entire intersection – including vehicle, pedestrian, and cyclist movement – in 3D; providing a complete view of an intersection, including several hundred feet in each direction.

That allows the agency’s traffic engineers to track all movements at intersections and identify areas for safety countermeasures.

Mark Taylor, Utah DOT’s traffic signal operations engineer, pointed out that the LiDAR system also captures data on red light runs, “near miss” situations, jaywalking, typical pedestrian pathway movements, and other key traffic movements. 

“We are always looking at ways to use emerging technology to increase safety on our roads,” he said in a statement. “This technology will help us pinpoint why and where safety issues are occurring.” 

[Editor’s note: The Utah DOT received an award for this intersection safety improvement effort from the U.S. Department of Transportation in January.]

For example, Taylor said LiDAR data will help Utah track “high frequencies” of near-miss crashes that, in the past, has been hard to track with real data, as well as “green light” times that are too short. “These, and countless other safety solutions, will be made possible through the patterns that LiDAR illuminates,” he explained.   

Utah DOT has installed LiDAR technology in several Salt Lake areas and is also testing LiDAR capabilities in conjunction with connected vehicle technology at two Provo locations—another area where pedestrians and cyclists are vulnerable. 

“The more we can get cars talking to our roads, the safer we will all be,” noted Blaine Leonard, Utah DOT’s transport technology engineer. “We’re hoping this LiDAR data will be another key component of this new connected future.” 

Utah DOT added that it is working with Panasonic in further developing this technology package and is using part of a $20 million grant issued by the Federal Highway Administration in June to expand this concept at other locations beyond Provo. 

Other state departments of transportation are also using LiDAR in a variety of high-detail mapping exercises.

For example, in June 2023, the Indiana Department of Natural Resources called upon the Indiana Department of Transportation for help “mapping” a historic water-powered grist mill at Spring Mill state park in Mitchell, IN, prior to the structure’s renovation.

The historic grist mill is located in the state park’s Pioneer Village – founded in 1814 – which contains 20 historic buildings to explore. The centerpiece is the spring-fed, three-story limestone grist mill, built in 1817, that still grinds corn today (though only for demonstration purposes) to produce cornmeal. INDOT noted that the last renovation of this grist mill occurred in 1930.

INDOT’s Land & Aerial Survey Office collected aerial imagery, light detection and ranging or LiDAR data, and other information on the grist mill via drone to create a three dimensional or 3D rendering of the building and water flume, including a fly-through video; a scaled and georeferenced point cloud of the mill building and water flume; and a publicly sharable link to an online geographic information system that features the 3D rendering and panoramic images.

And, in January 2022, the Mississippi Department of Transportation began using LiDAR-equipped aerial drones to help improve the efficiency and safety in the construction and maintenance of road projects statewide. Those drones take measurements and map out road construction projects while minimizing the exposure of ground crews to traffic, the agency said.

WSDOT Issues $26M to Port Electrification Projects

The Washington State Department of Transportation recently awarded $26.5 million to 11 state ports to help them electrify their operations.

These are the first awards through the Port Electrification Grant Program created by the state legislature in 2023 and funded by Washington’s Climate Commitment Act. The WSDOT said all 75 public ports across the state are eligible to seek grants from this program, which is part of a larger statewide initiative to reduce carbon emissions in the transportation sector.

“We are pleased to support cleaner air quality for those who live and work near the ports,” said Jason Biggs, director of WSDOT’s Rail, Freight, and Ports Division, in a statement. “This program helps ports switch from using fossil fuels, creates a better work environment for port staff and ensures nearby neighborhoods are healthier places to live.”

WSDOT is also involved in a related maritime project to replace the ferry vessels it operates with hybrid-electric models.

To that end, Washington State Ferries (WSF) – a division of WSDOT – recently contracted with ABB to help design and build new hybrid-electric-powered 160-automobile-capacity ferry boats.

Per the new partnership, ABB will select and integrate the technology that will power the new vessels, which includes the engine, batteries, and propeller system. The firm is also in charge of designing a “complete propulsion system,” will oversee the timely delivery of equipment, and offer expertise in equipment installation and commissioning as part of its contract with WSF.

ABB will also play a critical role in training WSF’s crews on the operation and maintenance of these new systems, WSDOT noted.

Oregon DOT Boosts Safe-Routes-to-Schools Support

The Oregon Department of Transportation recently distributed $1.4 million in grants to 14 school districts and community groups to get more children to safely walk and bike to school.

The roots of agency’s Safe Routes to School or SRTS program are in the former Federal Highway Administration program of the same name. When FHWA shut down the program in 2012, Oregon DOT decided to convert it to a state program through a combination of discretionary federal funds and dedicated state money.

Part of the program is for infrastructure improvements – designing and building sidewalks, crosswalks, and pedestrian and bicycle paths. The program also funds an educational and outreach component to raise awareness of and promote safe walking and biking to school, which are what the latest grants cover, said Heidi Manlove, Oregon DOT’s SRTS program manager.

Many of the 14 competitive grants will pay for coordinators who work with students, parents, school officials, and other community partners to find active transportation solutions to get students to and from school.

“The coordinators’ jobs are tough,” Manlove said. “There’s a lot of time spent knocking on doors, trying to get people to come together on this stuff. Some of it is fielding transportation issues and doing a walkability trip, or checklist, and seeing what some of the barriers are around the school.”

Coordinators look at entry and exit points and times for car pools and buses, alternative paths around the schools that could be used for walking or biking, and strategies that make the best use of infrastructure.

Sometimes, Oregon DOT must convince school districts or municipalities that there’s more to promoting a safe way to walk or bike to school than building a sidewalk or installing a flashing beacon, Manlove said.

“People want sidewalks, crosswalks, speed bumps, and oftentimes, we have to sell them on the education piece because they’re so focused on the ‘build-it-and-they-will-come’ approach,” Manlove said. “The coordinator is that liaison who bridges the gap to have those conversations.”

One strategy coordinators use is to create a “walking school bus,” a group of students who walk together and “pick up” more students along the way. At least one adult, or “driver,” leads the group.

Several other state departments of transportation, including Florida, Alaska, Indiana, and Massachusetts, also promote walking school buses in their SRTS plans.

While many schools express interest in the SRTS program, it isn’t a given that they are implemented everywhere. But once a school or school district starts the program, they quickly buy into it, she said.

Some of the groups Oregon DOT has funded in the past “now have managed to get funding in the school district budget,” Manlove said. Schools in the 38,000-student Beaverton School District program, for example, have embraced the SRTS program, “and the schools now are “doing (active transportation) education pieces during P.E. [physical education] class,” she said. “Even if those students aren’t walking or biking to school, they’re learning bike safety and pedestrian safety in P.E.”

Maryland DOT Helps Seal Regional Commuter Rail Deal

The Maryland Transit Administration (MTA) – a division of the Maryland Department of Transportation – and Virginia Railway Express (VRE) recently forged a new agreement that allows rail commuters with a weekly, monthly, or 10-trip tickets purchased on either the Maryland Area Rail Commuter (MARC) or VRE system to transfer at Union Station in Washington, D.C., to the other system (MARC-to-VRE or VRE-to-MARC) at no additional cost.

“This agreement represents a significant step forward in regional transit integration,” said MTA Administrator Holly Arnold in a statement. “We are not only fostering a more connected and efficient transportation network across our states but fueling economic growth by facilitating easier movement of people, supporting tourism and attracting business to the National Capital Region.”

This new “cross-honor program” enables travelers to seamlessly transfer between MARC and VRE trains on one ticket; simplifying travel logistics and promoting greater accessibility and affordability for the region’s commuters.

 It also underscores the commitment of Virginia, Washington, D.C., and Maryland to prioritize the needs of commuters and shape the future of regional mobility, noted VRE CEO Rich Dalton.

“This agreement effectively expands the geographic footprint of commuter rail service in the region and provides passengers with an affordable two-seat ride across state lines,” he said.

“It lays the groundwork for future efforts to better align MARC and VRE operations, which is consistent with our long-range plan to grow VRE from a peak-period, commuter-focused rail service to an all-day, bi-directional transit system that can better meet the transportation needs of a growing region,” Dalton added.

With this new program, MTA and VRE said rail commuters will gain easier access to connections between major National Capital Region urban centers, along with greater flexibility offered by the multiple transportation options available at Union Station.

Caltrans Unveils Transportation Project Prioritization Tool

The California Department of Transportation – known as Caltrans – recently unveiled a new tool designed to prioritize transportation projects that further California’s climate, safety, and equity goals in relation to state and federal grant applications.

[Above image by Caltrans]

The agency said the new Caltrans System Investment Strategy or CSIS updates the project evaluation and nomination process to better identify and promote multimodal climate-friendly projects in funding decisions.

The new tool fulfills a key action in the state’s Climate Action Plan for Transportation Infrastructure or CAPTI, said Caltrans, which calls for a data- and performance-driven investment strategy to more effectively align state and federal grant applications for transportation projects with the state’s ambitious climate goals.

“Deploying this forward-thinking and progressive investment strategy will not only significantly reduce our carbon footprint but provide a tool to vastly improve the safety, equity, and accessibility of our highway system,” explained Tony Tavares, director of Caltrans, in a statement.

Caltrans noted that this new analytical tool includes nine quantitative and two qualitative metrics to evaluate projects.

Quantitative metrics include safety, vehicle miles traveled, accessibility, the effect on disadvantaged communities, land usage, improvements to bicycle and pedestrian infrastructure, improvements to zero-emission vehicle infrastructure, and improvements to freight movement, while qualitative metrics include climate resilience and public engagement.

Caltrans added that it plans to use its new Equity Index tool, introduced in March, along with its new CSIS as part of the agency’s climate, safety, and equity goal alignment process for transportation projects.

Illinois DOT Helps Change Rail Line to Multiuse Path

The Illinois Department of Transportation recently outlined in a blog post how it helped transform an old railroad line and bridge in the city of Dixon, IL, into a trail for pedestrians, bicyclists, and other active transportation users.

[Above photo by the Illinois DOT]

The last train using the old Illinois Central Railroad line that once ran through the heart of Dixon rolled through the town in 1985. In 2016, the municipality began planning the conversion of that rail line into a multi-use trail with a combination of state and local funds as well as $3.4 million in federal funds disbursed by the Illinois DOT.

The initial phase of the project converted part of the line from Illinois DOT’s District 2 headquarters on Depot Avenue to Dixon’s downtown at Peoria Avenue and the Rock River. That initial $4.3 million project phase converted the rail line running over three stone arch bridges – listed on the National Register of Historic Places and rehabilitated in 1999 – to a lighted pedestrian and bicycle path that also features emergency call boxes for additional user safety. Approaching downtown, the trail leaves the rail line area via a graded wooden boardwalk designed to withstand the impact of Illinois winters.

The city also received $4 million in additional federal funding for remediation and environmental work at the old Dixon Iron and Metal Co., where the ramp from the old railroad connects with the riverfront trail at an area called Viaduct Point.

This project completes another phase of the Dixon Riverfront Masterplan, which had its conceptual beginnings more than 20 years ago, by helping complete Dixon’s Heritage Crossing Riverfront Plaza in which this path ties into.

The next phase of the project – called “Project Rock” and made possible through a $12 million federal Rebuilding American Infrastructure with Sustainability and Equity or “RAISE” grant – should start this fall and will extend the trail across the Rock River into Page Park. The city’s leadership also hopes the trail could eventually extend to the south end where it can connect with future parkland and Dixon’s gateway shopping area.

Other state departments of transportation are helping with similar locally-driven active transportation projects around the country.

Image by Utah DOT

For example, in May, the Utah Department of Transportation recently issued nearly $95 million to support 19 trail projects – including the construction of new paved trails as well as funding for planning efforts to fill in existing trail gaps – as part of creating a regional “Utah Trail Network” across the state.

The agency said that it collaborated with communities statewide regarding the allocation of that funding – approved by the Utah Transportation Commission – to select the key projects for this statewide trail network.

Of the projects selected for that inaugural round of funding, Utah DOT said 13 are considered construction ready and could get underway as soon as 2025 – depending on contractor schedules, supply availability and other factors like weather.

Additionally, in 2023, the Rhode Island Department of Transportation helped support – in concert with various federal, state, and local agencies – the new “Gotham Greens” off-road multi-use path along the Woonasquatucket River Greenway via stormwater mitigation efforts.

This new path, located behind the Gotham Greens building in Olneyville, offers new access to the Woonasquatucket River and serves as a connector between the Greenway and the Washington Secondary Bike Path – helping “knit together” a “patchwork of pathways” in the City of Providence to promote active transportation use while protecting the local environment from stormwater flooding.

New NCDOT Signal Policy Boosts Pedestrian Safety

The North Carolina Department of Transportation recently adopted a new traffic signal policy that aims to boost pedestrian safety.

[Above photo by NCDOT]

The new NCDOT policy states that, as new traffic signals are installed or existing ones are upgraded, they will be programmed with what is called a “leading pedestrian interval​” or LPI. That technology is designed to give pedestrians a “head start” of three to seven seconds in marked crosswalks before motorists on the parallel direction get a green light. This interval allows pedestrians to better establish themselves in the crosswalk to drivers who must yield to them before making a left or right turn.

“This change makes pedestrians more visible for drivers,” explained Nick Zinser, NCDOT’s Western Region signals engineer, in a statement. “It’s a safety enhancement, and it can be done at a low cost by reprogramming the existing equipment at our traffic signals.”

[Editor’s note: A new study from the Insurance Institute for Highway Safety or IIHS indicates that, in areas with few streetlights, motorists are more than three times as likely to yield to pedestrians at illuminated crosswalks versus non-lighted ones.]

LPI use is already common in the downtowns of the state’s largest cities of Charlotte and Raleigh, but NCDOT is working to add this feature at all signalized pedestrian crossings statewide. The agency added that North Carolina has over 3,500 intersections that have signalized pedestrian crossings.

Since making this policy change earlier this year, the department estimates 20 percent of those intersections now have a leading pedestrian interval for improved safety.

Going forward, the department and its municipal partners will continue to increase the number of locations with leading pedestrian interval capabilities, NCDOT said.

State departments of transportation across the country have been making similar pedestrian- and bicycle-themed safety improvements with enhanced or brand new active transportation policies introduced over the last few years.

For example, the Texas Department of Transportation is developing a Statewide Active Transportation Plan or SATP to gather recommendations for improving bicycling, walking, and rolling conditions across the Lone Star state.

In May, the Utah Department of Transportation issued nearly $95 million to support 19 trail projects – including the construction of new paved trails as well as funding for planning efforts to fill in existing trail gaps – as part of creating a regional “Utah Trail Network” across the state.

The Kansas Department of Transportation unveiled a revised active transportation plan in May 2023 to boost walking, bicycling, safe wheelchair use, skateboarding, and non-motorized vehicle mobility options across the state.

The Oklahoma Department of Transportation also began working on its first-ever active transportation plan in 2023 – a policy toolkit the agency said can be used internally and by Oklahoma counties and towns as engineers and designers look to develop more people-friendly infrastructure.

Meanwhile, the Washington State Department of Transportation unveiled a formal Active Transportation Plan in December 2021 – a plan that subsequently won the 2022 America’s Transportation Awards contest’s “People’s Choice Award.”
