In recent years, there has been a distressing increase in pedestrian-vehicle collisions, highlighting the vulnerability of pedestrians on the road. Several reasons have contributed to this surge including the unforeseen impact of COVID-19, which kept people off the roads for extended periods, leading to increased speeds and reduced vigilance. Moreover, distracted driving due to the prevalence of smartphones and electronic devices, impaired driving, speeding and inadequate pedestrian infrastructure have all played a role in pedestrian-related accidents and fatalities.

Combating this concerning trend necessitates a comprehensive approach encompassing awareness campaigns, responsible driving habits, and improved infrastructure to prioritize pedestrian safety and reduce these tragic accidents.

Here are five things communities can do to increase pedestrian safety.

Implement a Complete Streets policy

Communities should consider a Complete Streets transportation policy that prioritizes the safety and accessibility of all road users. That means finding balance and designing streets that cater to pedestrians, cyclists, public transit users and motorists. Complete streets encourage active transportation and promote pedestrian safety. With dedicated bike lanes, well-marked crosswalks and improved transit facilities, the policy fosters a pedestrian-friendly environment while enhancing overall traffic flow. By combining these elements and striking a balance, communities can advance holistic solutions to improve safety for all users. 

Protect students with Safe Routes To School

Safe Routes to School is a national program dedicated to enhancing pedestrian safety for students traveling to and from school. By funding and implementing infrastructure improvements and traffic calming measures, Safe Routes to School creates safer pathways, crosswalks and bike lanes for children. Moreover, the program emphasizes educational initiatives to promote road safety awareness and responsible pedestrian behavior. Cities should explore grant funding opportunities for safe routes to school projects. 

Adopt a policy on uncontrolled crossings

Uncontrolled crossings, characterized by the absence of stop signs or traffic signals, pose significant safety challenges for pedestrians. To address this issue, it is crucial to develop a comprehensive policy that clearly communicates what a community’s rules and priorities are at these types of crossings. Building local support is essential in gaining traction for the implementation of appropriate measures which could include installing marked crosswalks, warning signs, pedestrian refuge islands, curb extensions (bumpouts) or beacons to enhance pedestrian visibility and safety. By proactively addressing uncontrolled crossings, local authorities can create safer road environments and protect pedestrians and drivers from potential hazards.

Design facilities for pedestrians of all abilities 

Ensuring safe and accessible facilities for pedestrians with physical disabilities at crossings is of the utmost importance, a protected civil right. There must be sufficient signal crosswalk times so people with mobility issues can cross safely. Additionally, implementing detectable warning surfaces at curb ramps can serve as tactile indicators for those with vision impairments, alerting pedestrians that the protection of the sidewalk is ending and a crosswalk is beginning. Sidewalks should also be wide enough and without barriers, cracks, large gaps, etc. to ensure they are usable for people with disabilities including wheelchair users. 

By incorporating these features, municipalities can enhance pedestrian safety and create a more inclusive and accommodating environment for everyone. 

Consider the technology and tools that work best for a crossing 

Different types of beacons can serve different types of crossings, so communities should explore what works best. RRFB (Rectangular Rapid Flashing Beacon) warning lights can be installed, requiring pedestrians to push a button to activate flashing lights, alerting vehicles that people are crossing. Alternatively, a Pedestrian Hybrid Beacon, activated by pedestrians, can operate similarly to a traffic light, flashing yellow and red to control traffic flow. Although the Pedestrian Hybrid Beacon may cost more upfront, it becomes more advantageous for pedestrians in areas with higher traffic volume or faster vehicle speeds. By integrating these technologies, communities can improve the overall pedestrian experience and improve safety. 

How WSB can help

WSB plays a vital role in enhancing pedestrian safety and accessibility. We can help communities identify funding, develop policies, as well as scope, design, and construct pedestrian infrastructure enhancements. By thoroughly analyzing the impact of traffic solutions for vehicles and pedestrians, including those using mobility devices, they ensure comprehensive and inclusive planning, balancing the needs of pedestrians, bicyclists, and motorists. Drawing from their depth of experience, WSB actively listens to clients’ needs, tailoring individualized plans that address specific community needs. With a keen focus on safety, WSB considers existing speeds, crossing widths and traffic volumes to identify the most effective solutions to mitigate potential fatalities. Leveraging the latest technological tools for data collection, WSB can assess data to identify areas of highest need, allowing for practical and data-driven improvements.

In just a quarter century, the number of roundabouts has increased 3,000 percent across the country. Roundabouts are growing in prevalence because of how they can effectively, efficiently, and safely move traffic. Numerous designs and geometric shapes allow roundabouts to seamlessly integrate into our transportation infrastructure.  

Below are five facts about roundabouts – an infrastructure trend that’s here to stay.

1. Roundabouts improve safety.

A major reason that roundabouts have grown in popularity is because of their safety record. The designs help prevent serious crashes and fatalities. Slower speeds and the angle at which cars enter roundabouts significantly reduce the probability of head on and T-bone accidents.  Multi-lane roundabouts may have property damage only crashes when they are first introduced, but the chances for fatal or injury crashes drop significantly.  In most cases, crashes at roundabouts are fender benders.  

Pedestrian safety is also improved at roundabouts, although this can be a difficult concept for some to understand.  Most feel that because there is not the presence of a signal telling the motorist when to stop and the pedestrian when to go, that it cannot be safe.  However, there are several reasons the pedestrian crossing experience is improved:

• Slower speeds
• Shorter crossing distance
• Fewer conflict points
• Navigating traffic from one direction and refuge islands
• The pedestrian crosswalk is pulled back from the yield line allowing drivers to make a decision at the crosswalk before entering the roundabout

What’s more, because of their safety track record, they score well with many federal programs and are often eligible for grant funding.

2. Roundabouts handle high and low volumes efficiently.

Have you ever sat at a light for what feels like forever, even when there is no other traffic around? Roundabouts solve that problem, providing self-optimizing control. Roundabouts keep traffic moving. Roundabouts handle both high and low volume traffic well.  The effect of a rolling queue creates a situation where delay seems more acceptable to the driving public.  In the early 2000’s, many roundabouts were overbuilt based on the modeling results.  Many multi-lane roundabouts have since been retrofit to simpler geometry, and still perform operationally well. 

3. Roundabouts significantly improve access management in busy corridors.

In areas where there are many driveways and businesses along a corridor, it can be difficult for exiting traffic to turn left onto busy streets.   The implementation of a roundabout corridor allows left turns to be eliminated while access is maintained and for drivers to make a U-turn.  This creates a safer and efficient corridor.

4. Roundabouts have growing buy-in from the public.

When communities begin building roundabouts, there can be a fair amount of skepticism and concern from the public. As more communities adopt roundabouts and more drivers have successfully used them, that skepticism is significantly reduced.  

In communities that are new to roundabouts, a robust public engagement strategy is executed to educate the public. Public engagement tactics often include modeling, educational materials, visualizations and myth busting presentations that dispel the myths and provide education about the roundabouts, .

5. There are times when roundabouts are the wrong design choice.

While roundabouts are a growing trend, they aren’t right for every situation. Areas with high traffic volumes in one direction, with limited left turns on or to the side street, may not be ideal for a roundabout, as appropriate gaps may not be created. If roadways are already designed for traffic signals with multiple lanes, it may be more efficient to install traffic lights as opposed to redesigning a street for a roundabout.

Roundabouts are growing in popularity for a reason and are here to stay. Efficient traffic flow, improved safety, and operational efficiency make them a smart infrastructure choice for many communities.

Roundabouts move people and communities forward. 

Andrew is a transportation project manager and lead design engineer with over 20 years of experience who has designed more than 80 roundabouts. He is involved in all aspects of roundabout design, including geometrics, traffic operations, staging, and adhering to ADA standards. He has educated communities on the benefits of roundabouts and their safety for managing traffic. Andrew has also shared his professional knowledge nationally at international roundabout conferences.

Traffic signals are an often-overlooked aspect of everyday life. But when you stop at a traffic signal, did you ever also stop and think about how, where, and why these signals are used? Here are six things you may not know about traffic signals.  

When is a traffic signal needed?

Communities thoughtfully decide where traffic signals are needed vs. roundabouts or stop signs. An Intersection Control Evaluation (ICE) is conducted to determine the appropriate method of traffic control, which includes a detailed signal warrant analysis. These studies measure the existing vehicular and non-motorized (pedestrian/bicycle) traffic volumes and evaluate crash history at the intersection. WSB traffic experts conduct these evaluations in partnership with communities and local governments to collect the necessary data and determine if a signal would help improve the traffic safety and operations of the area. 

Traffic signals are typically designed to last more than 20 years with routine maintenance and designed to handle forecasted traffic volumes 20 years out. The federal government has requirements that must be followed when planning for the installation of new signals. These requirements include signal warrants that are found in the Manual on Uniform Traffic Control Devices (MUTCD). 

What are the benefits of a traffic signal?

Efficiency and safety are the top benefits of traffic signals. Signals are designed to keep up the progression of heavy traffic while ensuring there are no undue delays to side streets. The signals imitate elements of human decision-making, such as when a pedestrian should cross a busy intersection or when it is safe for a vehicle to make a left turn. Removing that decision from the person and incorporating it into an automated system like the traffic signal increases the overall safety for vehicles and pedestrians.

The ability to efficiently manage traffic flow can also be a significant factor in the success of local businesses and the livability of an area for families. For instance, access management developed by signals reduces the chaos of vehicles entering and existing businesses onto the main corridor.

How do traffic signals communicate with emergency vehicles? 

Traffic signals can change to the green phase for emergency vehicles allowing them to respond quickly and safely to incidents. Most emergency vehicles have an emitter on the dashboard that communicates with the traffic signal to safely end an opposing signal phase and bring up a green indication for the emergency vehicle. The technology also will extend the length of a green cycle if it is currently green for the direction an emergency vehicle is travelling.

Why do traffic signals always turn red for me?

Despite what we sometimes think, not all traffic signals turn red as you approach— in fact, it is just the opposite. Traffic signals have “dilemma zone protection,” which extends the length of a green light when a vehicle passes the back detection as it approaches the light. This keeps the light green to eliminate the human dilemma of whether to speed up or stop when the light turns yellow. 

Additionally, sensors in the ground at the intersection detect cars as they approach. For example, in many signalized locations, a minor street with lower vehicle volumes won’t change to green unless a vehicle is waiting at the red light to maximize the efficiency of the major roadway. 

What’s the latest innovation with traffic signals?

Flashing yellow arrows are one of the latest innovations in traffic signals. The flashing yellow arrow allows the driver to decide when it is appropriate to turn left, as opposed to controlling left-turns with green and red arrows. This feature on signals may also change based on the time of day. For example, the flashing yellow left turn arrow may be used on a Sunday night when traffic volumes are significantly lower. Then, during Monday morning rush hour, when traffic volumes increase substantially, the flashing yellow arrow will not be utilized, and the signal can offer a protected only phase because there is too great a risk posed to left turning vehicles trying to find an acceptable gap against the amount of oncoming traffic.  

What’s on the horizon for traffic signals?

One element of future traffic signals being considered more and more in major metropolitan areas is incorporating pedestrians and cyclists into the signal system. Engineers are rethinking classic intersection designs to incorporate new technology such as Audible Pedestrian Signals (APS) & ADA compliant curb ramp improvements, as well as bicycle markings for improving safety and accessibility for all modes.

Building that foundation has helped me learn about our client needs, understand their culture, and it has allowed me to build personal connections and relationships that I have taken with me throughout my career. Having that background has given me what I need to be successful in this role in terms of leadership and transportation knowledge.

What is your favorite part about leading the Texas transportation team?

I really enjoy the people side of leading. I see my role and team much like a sports team. I am the general manager, and I must understand the rules of the game, and the playing field, and I must analyze and put together a strategy for success. I am also in charge of recruiting the best talent and having the right players. I need to figure out their strengths and weaknesses and find what position fits best within the team and the organization.

How has transportation been advancing in Texas?

The transportation program has changed dramatically over the last year. I am really excited about the team we have built and the clients we have added. Moving forward, we have all the pieces we want in place, and I am really optimistic about the future. Fortunately, the market lines up with my optimism. TxDOT has a steady stream of revenue that will support infrastructure across the state. We are experiencing significant population growth that is stretching city and county resources, which means we need to help build the infrastructure to support that growth.

How has WSB grown? What factors do you think made this possible?

There are two factors that pertain to the growth of WSB. One is the market, along with the policies that elected officials enact. The other is the soft side, the people side. We are focused on our staff. We are committed to hiring staff that is well-known in the industry and well-respected by our clients which will help us to maintain relationships and foster new opportunities.

Why is the Texas market important to the growth of WSB?

The opportunities for growth in Texas are significant. The population and growth of the state are driving both the infrastructure and energy markets. As a company, our mission is to build what’s next in infrastructure and this is a great place to do just that. Our company roots in Minnesota and the deep bench of expertise we have throughout the country help position us for success. The infrastructure needs across our country vary and it helps us expand our knowledge and bring new ideas and innovations to our clients regardless of location.

What makes WSB best suited to support industry efforts in Texas?

WSB has a true understanding of the client’s needs. We believe in working with our clients to help them be successful. Many WSB staff in Texas have experience working for owners, contractors, and engineering firms. These experiences help us understand the challenges of our clients, the real purpose of delivering infrastructure projects, and an overall deep understanding of how to support industry needs.

What does WSB look like to you in the future?

There has been significant growth for the company, and I don’t see it slowing down. I see it accelerating more each day. It’s a big reason why I came to WSB. I was excited about the opportunity it would bring not only to myself but the staff as well. Our staff will continue to grow, and I am excited to see how everyone will fit into a larger organization. There will be a lot more opportunities and the company will be led by a lot of the younger leaders we have today.

Any advice for leaders now and for those who come after you?

Leadership is a lot like relationships and marriage. Always make sure to pick your battles wisely. Try hard to have a long-term vision with your decisions and actions. One thing that can be challenging in a large company is short-termism. Focused on the next quarter’s reports, and impacts today, and less focused on the long-term. I am impressed with WSB and our long-term vision and investments in staff and technology.
