Building Better, Safer Transportation Systems to Reduce Traffic Accidents

By Do Nam, Director of Traffic Modeling and Technology, WSB

The number of U.S. traffic deaths has been steadily increasing. According to the National Highway Traffic Safety Administration, vehicle fatality rates increased by 10.5 percent up to 42,915 last year, making it the highest number killed on U.S. roads in a single year since 2005.

The use of traffic modeling combined with cutting edge technology to mitigating risk, reducing traffic accidents, better protecting motorists and pedestrians, and analyzing ways to reverse the deadly trend of motor vehicle crashes. 

Trends, Statistics & Human Factors

Reports over the past two years have shown a significant increase in traffic fatalities across the nation. Much of this is attributed human factors like increased risk taking, which appears to have become more common in response to the pandemic.  

In 2020, when COVID-19 hit, the average vehicle miles traveled (VMT) decreased because much of the population was working from home and going out less. However, nationwide fatalities still increased from 36,355 in 2019 to 38,824 in 2020, and then up to 42,195 in 2021. With less traffic on the roads, many drivers were driving faster than the posted speed limit leading to more high-speed crashes. Furthermore, pedestrian, bicyclist, and motorcyclist fatalities were the highest they had been since 1989, 1987, and 1975 respectively.

The number of alcohol-related crashes also increased, which could be attributed to people consuming more alcohol to manage the social and economic stress brought on by the pandemic. 

Improved vehicle designs, seat belts, air bags, and new technologies like blind spot warning and automatic emergency braking systems have contributed to reduced vehicle fatalities over time, but cell phones and other distractions have caused those trends to reverse over the past decade. 

How Artificial Intelligence Improves Traffic Safety 

New emerging artificial intelligence (AI) programs assist engineers in collecting data, mapping out problematic traffic patterns, and predicting the likelihood of crashes. By using drones and traffic cameras to capture data from video, engineers use AI technology to track the movement of individual vehicles, bikes, motorcycles, and even pedestrians.

AI also allows us to better analyze traffic flow, determining work zone movements, space gaps between vehicles, and movements of heavy semi-trucks. Such advanced technology makes our analysis more informed and accurate. Through the use of data, we improve the flow of traffic, increase safety measures for drivers and construction workers, and predict where infrastructure changes are needed for more efficient and safer roads.

How Corridor Studies Play a Role in Community Growth

By Steve Lindsey, Director of Transportation, WSB

In 2021, Texas added more people to its population than any other state. For residents, businesses, and communities, it’s critical for planners to meet the immediate needs of citizens, while also planning for the future. For local, city, and county governments, corridor studies play a key role in creating and executing comprehensive transportation design that adapts to and meets the needs of growing communities.

What is a Corridor Study?

Corridor studies examine the relationship between roadways and adjacent land. In more densely populated areas, this can mean figuring out ways to overcome challenges where roadway expansion is limited. For land in development, it means looking at future population growth and where investments are being made to build homes, businesses, and public services.  Corridor studies also help ensure that if opportunities to acquire land becomes available – whether because they are being sold or planned for future development – there is a long-term view on how to best meet transportation needs.

Corridor studies are instrumental to help communities plan for 5, 10, and even 50 years down the road.

Trends in Community Growth

In Central Texas, Austin and the surrounding communities are growing rapidly. It is a technology hub with major companies like Tesla, Apple, Dell, and Samsung employing thousands of people. Densley urbanized areas have seen population growth, and more people are building homes and businesses in communities farther and farther from the city centers as the population grows.

Additionally, with the ongoing pandemic, we’ve seen more people looking to build homes, expand their space, and work remotely. With a hot housing market and population growth, more people are building and expanding into areas that were traditionally more rural or predominantly farmland.

Communities need properly planned transportation infrastructure to help transport people and commerce in those growing areas.

Working with the Experts

For community leaders facing growth challenges and working to plan for what’s next, it can be difficult to know when and where to start. When we partner with clients, we help them explore what opportunities their community can tap into in transportation design, and corridor studies are an important tool to get them and their community where they want to go.

Avoiding Vehicle Pileups

By DJ Sosa, Sr Project Manager, WSB

When winter storms sweep across the nation, dangerous road conditions can cause crashes, pileups, and leave commuters stranded for hours on end. How can road design play a role in making roads safer in the winter?

When roads are designed, many elements, such as drainage and flooding, are considered. Unfortunately, snowdrift prevention is often overlooked until after these disasters occur. What’s more, even long after snowstorms are over, snow can get blown back onto the roadway, requiring agencies to plow or push back the snow to clear the roadway. Significant snow accumulation, particularly on a “heavy” snow winter season, drives up maintenance cost for these agencies. Snow drift problems typically occurs on long, flat, rural stretches of highway. To create a snowdrift prevention plan, designers start by analyzing the terrain on both sides of the road. Determining how and where the snow is being picked up and drifted back onto the roadway is important in choosing which solution best suits the road.

Using that analysis, the following three options should be considered for minimizing snowdrifts and avoiding dangerous pileups:

Option 1: Wider Ditches

If there is adequate space, the best option is to have a wide ditch next to the roadway to create a “bowl” effect. These are ditches that serve as another area to capture the snow. Since roads are typically higher than the ditches, it blocks the wind and prevents snow from blowing back onto the roadway. This option requires a lot of room and typically involves additional right of way. If feasible, it is the top choice due to cost and maintenance. 

Option 2: Living Snow Fence

A living snow fence consists of trees, shrubs, or hay bales along the roadway. Farmers can work with their local department of transportation to line the road with hay bales, providing a cost-effective solution to block the wind from stirring up snow from the fields and on the roadways.

Option 3: Structural Snow Fence

This option looks like a robust version of a vinyl fence used for backyards that acts as a direct wind block. These fences often require coordination with property owners because they typically are on private property and outside of public right of ways.

These above three tactics can work for many roadways, but too often they are built reactively and only after a number of crashes, pileups, and other dangers already occurred. All options require room, more often, outside of public right of way. This requires transparent and consistent coordination with nearby residents. Discussions of the benefits for each tactic is key for the residents to allow any mitigation measures in the property. Because many Midwest states see snow for one-third to one-half of the year, agencies must be more proactive, many are now incorporating these tactics into their original planning and design. The Minnesota Department of Transportation, for example, is currently working on major interstate highways in rural locations and are including analysis of the corridor as part of the project. They have a whole department dedicated to working on snowdrift prevention.

Driver safety in winter is important and proper snowdrift prevention design can go a long way to saving lives, preventing crashes, and making roads safer for all of us. WSB’s transportation team can help advise on ways to make roads safer all year round.

Using Advanced Traffic Simulation Technology for Construction Staging and Maintenance of Traffic

By Do Nam, Sr. Traffic Operations Engineer, WSB

Construction operations on roadways disrupt normal traffic flow and generate undesirable delay. As traffic continues to increase throughout many metro areas, the Federal Highway Administration has been encouraging DOTs to be more proactive in their maintenance of traffic during construction. 

Good construction staging provides safe and efficient traffic operations throughout a project to minimize impacts on the community during construction. WSB has begun development of traffic models that simulate the flow of traffic under different staging scenarios. These traffic simulation models consider all available routes, how construction will impact these routes and how much additional time this will add for commuters. These models are being used to determine if there are improvements that need to be made on any surrounding routes to allow for better operations throughout construction.

This new approach is more proactive than past construction staging methods and is based upon data. By modeling actual construction conditions, we’re able to pinpoint where potential challenges may occur during construction and how to avoid them. Below is a list of potential benefits of construction staging and maintenance of traffic modeling using traffic simulation.

The benefits of advanced traffic simulation for construction staging and maintenance of traffic

1. By understanding what the impacts to the community are, we can be more proactive in mitigating them.
2. If we better understand what routes traffic will use, we can ensure that traffic controls are set up to accommodate additional traffic volumes.
3. Limit changes can be evaluated.
4. Informs decisions on critical maintenance items.
5. Provides a public engagement tool for cities and residents.

Through advanced traffic simulation technology, we’ve been able to enhance construction staging plans resulting in better projects.

US Fish and Wildlife Service decide listing monarch butterfly is “warranted but precluded”

By Roxy Robertson, Environmental Scientist, WSB

The United States Fish and Wildlife Service (USFWS) recently announced their decision to list the monarch butterfly under the Endangered Species act is “warranted but precluded”. The USFWS will not issue a proposed rule to list the monarch officially until 2024 due to insufficient funding and personnel. The listing will be evaluated annually to determine its eligibility and listing decision may be expedited under a new administration.

What does the USFWS decision mean?

• The “warranted but precluded” decision means that the USFWS has determined the monarch butterfly meets the definition of a threatened or endangered species, but the agency lacks the resources to take further action to list the species at this time.
• Since monarch butterflies still face threats and decline, there is a strong likelihood that monarch conservationists will challenge and litigate the decision.
• If litigation occurs, the USFWS could be ordered to prioritize the listing prior to 2024. This could result in a listing of the species within a short timeframe. If this occurs, partners enrolled in the Candidate Conservation Agreement for Monarch Butterfly on Energy and Transportation Lands (CCAA) are protected against regulatory actions that may occur following the listing decision.

Why is the CCAA important?

• By enrolling in the CCAA, partners will be protected against any regulatory actions that may result from future listing. Enrollment avoids risks to planned projects that may impact monarchs and their habitat by giving assurance that no additional regulatory requirements will be imposed by the USFWS beyond the terms of the CCAA agreement.
• The conservation efforts of enrolled partners will help to save the monarch species. This decision means that monarch butterflies are in trouble and unless the species experiences dramatic improvements in the next few years, a future listing of this species is certain.
• Enrollment in the CCAA demonstrates the partner’s commitment to conservation of this species.

Using 4D/5D to Mitigate Risk and Identify Project Opportunity

By Kelsey Peterson, Graduate Engineer, WSB

4D/5D modeling is intended to improve the accuracy and efficiency of projects. It has applications throughout the project life-cycle, from preliminary design to project close-out with the contractor. Learn more about some of the ways incorporating into your project and improve your projects overall success.

4D models help mitigate project risk by visualizing project conflicts that are not easily identified in traditional Gantt style bar charts. A 3D model linked to a project schedule provides the project team the opportunity to identify and mitigate project staging, utility, and discipline conflicts by providing a visual of how construction will play out as a function of time. It also provides a visual of project opportunities, allowing the project team to reschedule activities that may be better sequenced to reduce construction delays and cost, as well as redesign the 3D model to include missing design elements that would otherwise delay construction. Project time and cost savings are the direct result of using the 4D model to identify and mitigate project risks early on in construction.

The 4D/5D models provide a level of transparency that encourages coordination between project team members, creating team accountability through clear vision of project construction. The 4D/5D model is used to bring project conflicts to the surface and create the opportunity for project team members (owner, contractor, engineer, and project stakeholders) to resolve challenges in a collaborative environment.

4D/5D modeling enhances project coordination by allowing new project team members and stakeholders be brought up to speed quickly on the design and staging of the project. This greatly enhances project communication relative to the use of a traditional Gantt style activity chart. It also provides the opportunity for developing staff to become familiar with a project that may, historically, have been easier for a more senior staff member to visualize. The 4D/5D model allows the project team to develop and review a safety plan visually and highlight construction activities where accidents and risks can be reduced prior to the activity occurring on the project.

By incorporating 4D/5D modeling, your projects will run more smoothly and efficiently. It allows you to mitigate risk though the application of a timeline to the overall plan creating greater vision and improve efficiency by encouraging team work and increasing overall project vision.
