Signal Spotlight: Norwalk’s New Adaptive Traffic Signals
The City of Norwalk has begun to implement new “Adaptive Traffic Signals” that will automatically adjust the cycle length and distribute green light time. The system will accommodate changing traffic patterns and helps ease congestion.
What are adaptive traffic signals?
Adaptive Traffic Signals adjust the timing of their green light cycles to match current traffic conditions on the roadway. The system constantly collects data of approaching vehicles and creates new timing sequences and adjusts accordingly. The signals will change based on traffic patterns in the area rather than a standardized shift from red to green.
The main benefits of adaptive signal control technology over conventional signal systems are that it can:
Automatically adapt to unexpected changes in traffic conditions.
Continuously distribute green light time equitably for all traffic movements.
Improve travel time reliability by progressively moving vehicles through green lights.
Reduce congestion by creating smoother flow.
The City of Norwalk began to imagine a citywide Traffic Adaptive System program in 2018.
The 1st phase of the Adaptive Signal System was completed in 2019 with implementation of 8 adaptive traffic signals on West Avenue as part of the SoNo Collection project.
The 2nd phase of the Adaptive Signal System will add 8 more signalized intersections on West Avenue and Belden Avenue to the Adaptive Signal System Network under LRARP funding. This project will be completed by the end of 2022.
The 3rd phase of the Adaptive Signal System will add another 14 signalized intersections in South Norwalk on MLK, South Main Street and North Main Street to the Adaptive Signal System Network as part of the Walk Bridge project. This project will be completed late this year or early next year.
The 4th phase of the Adaptive Signal System will add 3 more signalized intersections on East Avenue to the Adaptive Signal System Network as part of phase 4 traffic signal upgrade under CMAQ founding. This project will be completed by the end of 2023.
The 5th phase of the Adaptive Signal System will add 21 more signalized intersections to the Adaptive Signal System Network. These signalized intersections are located on Route 1, East Avenue, Martin Luther King Boulevard, and South Main Street. This project will be built under the recently awarded CMAQ founding. The estimate time of completion is the end of 2024.
The City’s goal is to complete the Traffic Signal Adaptive System project by the end of 2025.
Along with implementing the Adaptive Signal System, the exclusive pedestrian crossing phase will be replaced with concurrent phasing and the LPI (Lead Pedestrian Interval) where appropriate. As part of these changes, all regular pedestrian push buttons will be replaced with an (APS) audible push button system.

Happy Spring! As the weather improves and we all start to get back outside walking and biking, roadway safety becomes even more important. Many of you are familiar with RSAs or Road Safety Assessments/Audits, but for those who may not be, an RSA is a formal safety evaluation of a location, performed by a multidisciplinary team. It is different than a traditional safety review in that it considers all potential road users, includes team members with varied expertise, accounts for human factor issues and results in a formal written report. These assessments, which are a Federal Highway Administration Proven Safety Countermeasure, are a valuable tool for municipalities of all shapes and sizes to evaluate roadway safety for all users.
So why should you perform an RSA? There are several reasons actually! Maybe you have an area where residents are concerned about children walking and biking to school. Perhaps you are planning changes to a roadway and want to ensure that all users are accommodated in the final improvements. Or maybe your community has an area that experiences seasonal increases in vulnerable users and you’re interested in potential safety improvements. All of these, and more, are reasons to conduct a Road Safety Assessment.
For example, the City of Stamford requested assistance from the Safety Circuit Rider with an RSA for Strawberry Hill Avenue, one of their busiest north/south corridors. The area has a mix of schools, businesses and residences and has some pedestrian amenities, but some are outdated and in need of improvement. According to Frank Petise, P.E., Bureau Chief of Transportation, Traffic and Parking for the City of Stamford, “For those of you who haven’t taken advantage of the program, I highly recommend it. Melissa did a great job.” The City plans to use the RSA report to support future improvement projects and potential grant funding.
Whether you have been thinking about conducting an RSA and just haven’t scheduled it, or you have never considered one before, now is the time! Many of the recommendations that come from these assessments are short-term and could be implemented within the next several months, before cold weather sets in again.
If you would like to schedule a Road Safety Assessment or are looking for assistance with local road safety in your community, contact Melissa Evans, Safety Circuit Rider, at firstname.lastname@example.org.
At the end of February, I had the opportunity to give a presentation to a UCONN graduate class, Seminar in Transportation and Urban Engineering. I was provided a similar opportunity last year as well, and I truly appreciate the chance to speak to these students. The relationship between the University’s School of Engineering and the T2 Center is an important and valuable one, and these presentations reinforce that connection.
Prior to my presentation, I recently had an experience working with a group of senior design students from another university and realized they weren’t familiar with some of the Proven Safety Countermeasures from the Federal Highway Administration (FHWA). It seemed like these tools would be valuable information for students to have as they prepared to enter the world of engineering and roadway safety. My UCONN presentation highlighted FHWA’s newly revamped Proven Safety Countermeasures website and the recent addition of nine new countermeasures, for a total of 28. I also had the chance to explain what we do at the T2 Center and what services I provide as the Safety Circuit Rider.
The students were engaged and asked several questions about the information I provided. I also shared my presentation with them so they could reference the material afterwards. I shared several examples of installed Proven Safety Countermeasures around the state, and we discussed their safety benefits. The T2 Center’s website, which I also shared with them, maintains a repository of Connecticut Safety Examples and identifies those that are Proven Safety Countermeasures.
The opportunity to connect with the future transportation professionals of Connecticut is one that I welcome and embrace. The more information we all have on roadway safety and the more tools at our disposal, the safer all of Connecticut will be.

Installing public art on traffic signal cabinets can enhance the beauty and sense of place in a community. Artwork depicted on the cabinets often reflects the unique characteristics of the neighborhood, especially when local artists and students get involved in the project. According to Forbes Magazine, painting colorful murals on surfaces also reduces vandalism by up to 95%. In areas hard-hit by graffiti, keeping surfaces clean requires significant resources and staff time. Some vandals do still target surfaces painted with murals, but the time and effort required for graffiti removal is reduced.
There are several options for applying images to a traffic signal cabinet. The first is painting, which typically consists of a layer of primer, paint, several coats of a UV-filtering clear coat to protect the art from sun fading and a layer of wax or other treatment to allow for successful graffiti removal without damaging the clear coat. Painted artworks typically last five to six years.
Another option is to use a layer of thin, adhesive vinyl to wrap the cabinet. The artwork is submitted as a high-resolution digital image which is then printed onto the specialty vinyl wrap material. The material is applied to the exterior of the traffic signal cabinet and typically has a useful life of five to ten years.
Many cities have an ongoing traffic signal cabinet art program, often sponsored by a local or regional art commission. The art is typically funded through grants, private contributions and business sponsorships. The cost to apply artwork to a cabinet typically ranges from $800 to $2,000, including materials and an optional honorarium payment made to the artist for their time.
Before soliciting artists to decorate signal cabinets, there are a few items that should be considered. The first is that only town-owned equipment may be painted or wrapped. The Connecticut Department of Transportation (CTDOT) does not allow artwork on state-owned traffic signal cabinets. Agencies should establish a clear process for accepting, processing and voting on applications. Guidelines should be provided for imagery that is acceptable and unacceptable in a public space. For example, text can be distracting to drivers, so a best practice is to keep it to a minimum or place it on the side of the cabinet facing away from traffic.
Maintenance responsibilities should be determined ahead of time, and guidelines should be provided for ensuring long-lasting art installations. Low-quality paints, interior paints and paints of different brands mixed together tend to produce inferior results. Commercial or industrial grade materials should be specified. It is also important to communicate to the artist that hinges, door handles and vents should not be painted over and need to remain fully operational. Finally, it is helpful to determine what will happen when the art installation reaches the end of its useful life, whether that means returning the cabinet to its original state or commissioning a new mural for the cabinet. For an example of a cabinet art program in Connecticut, check out the Norwalk Traffic Graphic Program.

You may have heard the term Road Safety Assessment, or Road Safety Audit, or RSA and wondered what it meant. Perhaps you know what an RSA is but aren’t sure why you should consider them for your community. Road Safety Assessments are formal safety evaluations of a location, performed by a multidisciplinary team. RSAs differ from traditional safety reviews in that they consider all potential road users, include team members with varied expertise, account for human factor issues and result in a formal written report. They can be performed at all stages of a new project and can also be done on existing roadways as a means to identify safety issues and identify opportunities to mitigate those issues.
The Federal Highway Administration (FHWA) has identified RSAs as a Proven Safety Countermeasure that can result in a 10%-60% reduction in total crashes. Many communities are successfully using these assessments as an opportunity to address safety concerns on existing roadways or at intersections. An RSA is also a useful tool in the planning process of a safety improvement project to ensure that all road user needs will be met. An assessment can even focus on a particular type of user such as pedestrians or bicyclists, especially if the location being evaluated experiences high volumes of those users.
Conducting a successful RSA starts with putting together a diverse team. Members should consist of representatives from Public Works, Planning, Emergency Services, Engineering and the Chief Elected Official’s office. Representatives from a neighborhood action group or association can participate to provide the resident perspective. Additionally, the Safety Circuit Rider program assists municipalities with road safety assessments on local roads.
Several municipalities in Connecticut have performed RSAs, with the assistance of the Safety Circuit Rider, to identify safety improvements to busy summer destinations, downtowns, school areas and more. These communities have used the resulting reports to further traffic calming and complete streets initiatives as well as to pursue grant funding for safety improvement projects.

Mini-roundabouts, while smaller than standard roundabouts, function similarly. Roundabouts are circular, unsignalized intersections where all traffic moves in a counterclockwise direction around a central island. Unlike regular roundabouts, mini-roundabouts have an Inscribed Circle Diameter (ICD) of 90 feet or less. With this smaller ICD, the central island and all splitter islands are of a mountable design that is typically two and a half to three inches in vertical height, making them traversable, or they are painted.
Mike Vaughn of the Kentucky Transportation Cabinet (KYTC) references an old adage when explaining mini-roundabouts. “As the saying goes, ‘There is a time and place for everything.’ Mini-roundabouts are small and the small footprint means a mini-roundabout cannot process as many vehicles per hour as a regular sized roundabout…Mini-roundabouts work best in locations with low overall traffic volumes, low truck traffic, and low speed.”
When designing a standard roundabout, large truck traffic is a priority; conversely, if you’re planning a mini-roundabout, the focus is on the rest of the traffic: smaller, more common vehicles. Both types of roundabouts provide traffic calming benefits, employ pedestrian safety measures, and can be used in various scenarios and circumstances.
FHWA highlights many benefits of mini-roundabouts in their technical study. As Vaugh alluded, mini-roundabouts may not always be the best solution, but there are many circumstances in which mini-roundabouts fit the bill. Overall the popularity of mini-roundabouts is growing due to these compelling factors:
Compact Size – A mini-roundabout is often compact enough to fit into an existing intersection.
Traffic Safety – Studies show that crash rates are lower in mini-roundabout intersections.
Traffic Calming – As speeds are reduced on roundabouts, they can often produce traffic calming effects.
Access Management – Mini-roundabouts can provide access to up-and-coming residential or commercial developments.
Environmental Benefits – Fuel consumption and vehicle emissions are reduced with utilization of mini-roundabouts.
Mini-Roundabouts in Connecticut
Although Connecticut has been constructing more roundabouts in recent years, mini-roundabouts are still a new tool. Below are two examples of mini-roundabouts found in the state: one with traversable stamped center and splitter islands and one painted.

“Ordinary Superpowers” by Mark Henson – Book Reviewed by TLP Cohort #7 Member
Author, Author Mark Henson, in chapter one of his book Ordinary Superpowers, says, “I believe with all my heart that you don’t have to change THE world. You just have to change YOUR world.”
The idea that we should strive for self enhancement and personal improvement over accomplishing large-scale feats and grandeur is one that, I believe, is lost on most people today. I believe that society has led us to a place where being oneself, inherently, doesn’t carry much weight on the side of being that extraordinary person that can break through and change the course of the world as we know it. Mark Henson makes numerous references, in this book, to “extraordinary” superheroes, such as Batman and Superman, with their extraordinary superpowers and ability to save the day for the world to see. These are stories that, for me, were etched into my mind and set the bar high for personal accomplishment.
Sure, we are all familiar with things that are our strengths, things that come easy to us, things that we know we can exploit and use to our advantage to earn some level of success and accomplishment, but, perhaps, we haven’t really explored which of those strengths or attributes, if any, are ones that, when isolated and strengthened, could propel us to a level higher than we’ve ever imagined, or if they could help to elevate someone else, perhaps many others, to an unimaginable height or level of success.
Though the idea of nurturing and growing one’s self sounds easy, perhaps, it’s not. Perhaps we get too caught up in the mundane, day to day, drudgery that we have come to know and rely on for its monotony and predictability, to realize that we are capable of so much more. Perhaps we need a little nudge, here and there, to remind us of how great and accomplished we can be, and how much we can do to contribute to the greatness of others. Mark Henson has learned that, through self-evaluation, reflection, and perspective, we all possess “superpowers” that may not be worthy of a skin tight suit, cape, or mask resembling that of a winged creature of the night, but ones that are capable of really changing OUR worlds, if we choose to understand and nourish them.
For me, the concept of “Ordinary Superpowers” is one that I have pondered in the past, but, have never assigned a label to. I believe that every person is a unique being that is perfectly designed to do exactly what it is that they were designed to do. The hard part is figuring out exactly what that is. I have often tried to evaluate myself, from many perspectives, but professionally and societally, more often than not.
Perhaps it is with hard times that we look for our place in the world. Perhaps it is then when we look ourselves in the mirror and wonder why we are here and how we can do better for ourselves and for others, and, perhaps we lose focus, when hard times transition back to good, and never zero in on what those things are. Mark Henson, in this book, encourages his readers to try to identify the things about us that are particular to us and though not unique, from the standpoint that there is, likely, someone somewhere with a similar skill, is an ability that we possess, and is one that stands out amongst a familiar crowd. He labels these particular skills “Ordinary Superpowers” and offers insight and direction for building on them.
I think that this is a concept that can be quite difficult for people to grasp, not from the level of understanding the idea, but from actual self-reflection and analyzation of what is good about them, what is great about them, what is not so great about them, and what qualifies as a “superpower”. Let’s face it, It is always easier to identify what is great about someone else, and even easier to identify their flaws, but a tough pill to swallow when tasked with identifying those things about ourselves. I think that, conceptually, if you can be open minded enough and have the propensity to WANT to do better for yourself, and moreover, others, the author leads you on a detailed path towards focus and understanding to get you to the level of elevation that he has found for himself. Again, I believe that it is one of the most difficult things in life, to be critical of yourself enough that you can view yourself from a third person perspective, identify your strengths and weaknesses, and determine which ones stand out amongst the rest. However, I do believe that, with some effort, we can all get to a place where we have identified, at least one, of our “Ordinary Superpowers”, however big or small, and nurture it until it becomes a tool, in our belt, along our journey towards success.
Mark Henson encourages his readers to reach out to those that know them best to help identify their “superpowers”. I found that people that “know you best”, may or may not share the same perspective, looking in, as you do, and moreover, may provide you with an assessment that is notably biased and almost expected. However, in my journey towards identifying even one of my “Ordinary Superpowers”, I was able to gain some perspective, from someone close to me, that helped me to realize that one of my superpowers comes in two parts, passion and compassion. I would be the first one to tell you that I am a very passionate person, sometimes to a fault, but often aimed at success. When I asked about the “compassion” part, it was noted that I will not let anyone fail, and will exercise the same level of passion, I would normally reserve for myself, to lead others toward success. I think that passion is a superpower, because it allows me to, not only, maintain a path for myself, but to mentor, educate, and motivate others for success. Someone that is passionate about something exudes that energy for others to grab on to and can help to motivate others for success, even when there is no real benefit to them in the long run.
Though I juggled a couple of other “powers” around, while on my voyage, it came to me that my level of curiosity is somewhat special. As an adolescent in school, my curiosity lacked focus and would tend to lead me down a path toward nowhere rather than the upward route it does as an adult. I find myself wanting to know more about everything. Its not just enough for me to know that something works, I want to know how and why. This level of curiosity can, sometimes, be viewed as a nuisance, by some, but pushes me to reach beyond the line of routine, or common, understanding so that I can gain a level of knowledge that extends deeper than that on the surface. To some, perhaps, my curiosity could be viewed as needing to know more than necessary, or metaphorically speaking, overfilling my cup. For me, the curiosity is a hunger. It is a yearning for information and understanding. It is guiding me on my path towards enlightenment and success. It is “property” that I acquire and I own for my personal use, and to offer to others who may need it along their journey.
When I think about joining my curiosity and hunger for knowledge with my passionate commitment for success, I realize that I have so much more to offer myself and my future, and that of those around me, both personally and professionally.
Lastly, I have identified my ability to articulate my thoughts, and the thoughts of others, through words on paper as an “Ordinary Superpower”. Again, as an adolescent, I was more focused on my superpowers on the gridiron, and in the hallway, than I was for knowledge or education. I never appreciated what it was to be able to take a thought or a feeling or an emotion from myself, or from someone else, put it on paper, and have someone read it and actually feel it through the words in print. It wasn’t until I was threatened with graduation, for a less than good average in English class, that I realized that this was not only something that I could do, but something that, perhaps, a lot of people cannot. Now, as an adult, and not threatened with a less than good average, it brings me a feeling of fulfillment when I can assist someone with organizing their thoughts and feelings and emotions, put it on paper, make it make sense, and allow them to share it with the world. Whether it be for wedding vows, a best man’s speech, a letter of intent, a proposal for services or materials, or a routine e-mail, I view the opportunity to write and to be heard as a great one. I am humble enough to know that I am no great author, but I do possess a couple other superpowers, as noted above, that give me plenty to write about. Often I find myself looking for an outlet, a place where I can write about the things I’m passionate about and the things I’ve learned through incessant questioning and curiosity. Perhaps, by refining and combining my superpowers, I will find myself in a place to better myself and the world around me. Words spoke, however knowledgeable and passionate, are only words in the wind if not in print. Mark Henson suggested, in his book, to try and identify three superpowers. Three, at the beginning of this journey seemed impossible. I’m convinced, however, that three could be just the tip of the iceberg IF someone hungers for success and is willing to dig deep below the surface, seek clarity, and practice refinement.
I am a person that whole heartedly believes that a chain is only as strong as its weakest link. I believe that a team is only as effective and successful as its weakest member. From a leadership perspective, I believe that we need to work just as hard, if not harder, for those that work for us in order for any one of us, or all of us, to be successful. I am a person that longs to pass knowledge and experience on to those that long for it. I am motivated to succeed, not just for myself, but for those that accompany me, above or below, on our journey towards achievement. I am passionate about that journey. I will go above and beyond to support those that need to be supported and to share my passion, my superpower, with those that need a lift along the way so that we may rise together. I will focus on and nurture my passion and enthusiasm so that it becomes stronger. I will continue to ask questions and learn as much as I can about as much as I can and, in turn, will pass that knowledge on to the curious and the questioning. And I will continue to write whenever I can, even if it is just for myself. I will put my thoughts on paper, I will continue to use that superpower to help others and I will continue to refine that power so that, someday, my words may educate or empower someone to do something great.
I will make a conscious effort to grow these powers and to expand my mind in hopes that, in time, they will help me to make a difference.
Mark Henson noted that everyone’s “Ordinary Superpowers” are different. They are uniquely theirs, perhaps not one singularly, but in combination with each other, and as such, we need to rely on those around us, that truly support us on our journey and supplement our superpowers with theirs, and we can achieve success unparalleled. He reminded us that we should not discard relationships because someone’s superpowers, or lack thereof, either don’t mesh well with ours or actually steal energy from ours, but to shift the energy and the dynamic of that relationship such that it can no longer hinder us on our way or rob us of the calories needed to take the next step.
The author said, “To multiply your powers, you must have people in your corner who complement your abilities”. I believe that we are strong and capable, stand alone, beyond what we can comprehend. I am certain, however, that we cannot fathom our capabilities when we unite and cooperate.
In closing, Mark Henson reminded his readers that “Instead of trying to “be legendary,” why not just try to be you? “. I think this was the perfect ending to the journey he shared and the insight he offered. There is nothing more profound than learning to “just be you”, even if you have certain “superpowers” that make you great. We have all seen instances where success has led people to lose sight of who they are and where they came from, and I think that encouraging people to be super, yet humble, is the perfect recipe for a future filled with success, fulfillment, and happiness.
Traffic signal cabinets are typically locked to prevent equipment damage or theft and, more importantly, to protect road users from the safety and liability risk of a malfunctioning or non-functioning signal due to tampering. Traditionally, traffic signal cabinet locks use a standard #2 key. This provides a level of convenience as signal technicians, engineers, and contractors can all access the cabinet. However, these keys can easily be purchased on the internet. This means anyone can obtain a #2 key and access any number of traffic signal cabinets with the agency operating the traffic signal left unaware. If an employee drops their key, an individual could pick it up and use it to tamper with or steal cabinet equipment.
With the introduction of electronic controllers with networking capabilities, the role of traffic signal cabinets has changed. In the past cabinets simply housed electromechanical equipment, but now they are used to provide a vital level of network security. Increasingly, municipalities are connecting traffic signal controllers to their computer networks to allow for central control of the signals and monitoring of camera feeds. The need to protect the computers and sensitive information on these networks has prompted manufacturers to produce new security solutions that can be installed in new cabinets or retrofitted in existing cabinets.
One option for increasing security is a high-security mechanical lock. To provide convenience, these locks can be keyed so that all of the traffic signal cabinets in a system use the same key. These locks are usually designed to be resistant to the elements and to lock picking. One consideration with this type of lock is the management of keys. If a vendor requires access to the cabinet, the agency must provide them with a copy of the key or travel to the intersection to provide access.
Another option is an electromechanical lock. These locks use an electronic key to provide access control using programmable keys. Some of these keys require recharging, while others are designed with built-in batteries. Some batteries are replaceable, while other keys are designed with non-replaceable batteries and must be disposed of and replaced when the batteries die. Some manufacturer software provides an audit log for monitoring access to the cabinets, and there are systems that allow for timed access to the cabinet during pre-set time periods. If keys are lost, they can be reprogrammed using the software to prevent access to the cabinet. These systems have the benefit of increased accountability and security but can be inconvenient if a key loses its charge or the battery dies.
A third type of access control relies on passcodes or RFID proximity cards to disengage a solenoid and provide access to the cabinet lock. Once access is provided, a standard #2 key can be used to open the lock. A benefit of this type of system is that it does not require a special key that needs to be charged. One thing to note about these systems is that they are powered through the cabinet and can default to either the cabinet being unlocked or the cabinet being locked until power is restored.
However an agency decides to limit access to its traffic signal cabinets, it is important to involve any stakeholders who may need access to the cabinets. This will ensure that the system will meet all of the agency’s needs, securing the cabinets while allowing necessary access.
