Rhythm Engineering Gets the Green Light for the Kansas City Streetcar Traffic Signal Project

Kansas City, MO: Rhythm Engineering, LLC is proud to announce that it has won the contract for the upgrade of the traffic signal control system to be installed along the Kansas City Streetcar corridor in mid-2015. The Kansas City Streetcar project, known as KC Streetcar, is a two-mile line that runs through downtown Kansas City, largely on Main Street, and connects River Market on the north to Crown Center and Union Station on the south.

Since the new streetcar system will run on existing street lanes in the middle of the Central Business District, Crossroads Art District and the Power and Light District, traffic signal synchronization is crucial for alleviating any potential traffic congestion that may arise. Rhythm Engineering offers the perfect solution, using its newly developed adaptive technology, In|Sync®, which integrates signal timing, traffic volumes, and computerized real-time tracking. Their system, once installed, will control 21 signals along this streetcar corridor.

According to Reggie Chandra, PE, CEO of Rhythm Engineering, “We are honored to have this opportunity to make a difference in our own home community. Kansas City has proven that it is very serious in its intention to become a truly “smart” city and we are glad to be part of the initiative. Rhythm Engineering always has been proud to be called a Kansas City company as we make a difference to motorists in 31 states and 128 cities.”

These modifications will be installed by Rhythm’s traffic technicians and optimized by traffic engineers to ensure that the streetcar can move safely and efficiently alongside car and bus traffic. Rhythm Engineering joins other subcontractors, including Cisco, Comanche Construction, Reynolds Electric, Trekk Design, and others, under the direction of the project team led by KC Streetcar Constructors, a joint venture partnership of Herzog Contracting Corp. of St. Joseph, Missouri, and Stacy and Witbeck, Inc. of Alameda, California.

7 Traffic Signal Myths Debunked


Have you ever wondered how we process traffic signal information? It all starts with our early driving experiences and actually, over time, we learn to automatically block out traffic signals during our daily commute. That is, we block out the signals until we get caught at lengthy, numerous red lights over a relatively short distance. At that time, our focus then turns to the nuisance they cause – long delays to our final destination, road rage, and misconceived notions about the benefits of traffic signals (or lack thereof).

Click here to read about Oscar’s story.

In reality, the purpose of traffic signals is to solve traffic conflicts. We all want to be in the same place at the same time, but this would only lead to accidents, severe traffic jams, and ultimately, chaos.

To help you and those motorists out there, there are a number of preconceived ideas about traffic control that are absolutely incorrect and lead to frustration and unnecessary stress. I’d like to share the 7 myths that motorists actually believe about stoplights and other traffic signals.


Myth #1: The Flasher. If you flash your car’s high beams at a stoplight, it will turn from red to green more quickly.

Reality: Traffic light sensors do not detect headlights; they use other means to detect traffic at a light. Emergency light sensors read encoded and proprietary infrared signals from special emitters installed in emergency vehicles.

Myth #2: The Pusher. If you push the pedestrian crossing button multiple times or in a set pattern, you can trigger a green light faster.

Reality: While many of us are guilty of pushing the cross button over and over, it has no impact on how quickly the signal changes. When you push the button, the event gets recorded in the memory of the traffic signal controller (just as if you push an elevator button). This signal is then used to time the light change, nothing more.

Myth #3: The Weight-Builder. The amount of weight present at an intersection triggers a green light.

Reality: The weight of a vehicle has nothing to do with triggering a green light indication. Vehicle presence is detected by inductive loop technology, which works on the principle of electromagnetic induction, and all that is necessary is a vehicle having sufficient iron in the metal for detection and stopping over the inductive loop which signals the traffic controller that there is traffic waiting at the intersection.

The only vehicles potentially affected may be motorcycles or mopeds, but this can be overcome by drivers pulling near the corner of the lane near the stop bar painted at the intersection.


Myth #4: The Unseen. Traffic lights are changed by tripping an invisible curtain that covers only a section of the lane.

Reality: Vehicles trigger the inductive loop (see Myth #3), and as long as they have sufficient metal and stop in the right spot – just before the stop bar, the thick white line painted on the pavement that signals to motorists where they should stop in order to be effectively detected by the traffic controller.

Stop too far past or before the bar and the pavement sensors can’t detect your presence. As a result, motorists who do not stop at the stop bar generally end up waiting longer at intersections!

In order to be detected, motorcycles and bicycles also must stop before the stop bar. The in-pavement detectors are most sensitive at the corners. So, motorcycles have a better chance of being detected if they stop at the corner of the lane just behind the stop bar too.

Myth #5: Remote Controlling. You can turn the stoplight green through the use of a universal television remote.

Reality: You cannot program a remote with a special code in order to change traffic signals. This myth stems from an Internet spoof and holds no truth. Sensors associated with preemption systems are programmed to only detect certain infra-red signals from emergency vehicles and cannot be fooled or tricked into activating a green light for passenger vehicles; and for good reason.

Imagine the chaos if every impatient driver with access to a Radio Shack, took it upon himself to direct traffic according to his whims!

Myth #6: Big Brother Is Stopping You: Governments or cities purposely implement policies that do not allow traffic to efficiently flow through intersections.

Reality: Most traffic lights are poorly timed and inefficient because transportation agencies don’t have the personnel or financial resources to update their timing plans or implement newer traffic technologies that could reduce delay at intersections. Without experienced personnel or money for updates and improvements, cities are unable to improve the efficiency of their traffic control systems and motorists, by default, are stuck wasting time and fuel at red lights.

Myth #7: The Safety Patrol. Traffic signals always reduce collisions.

Reality: The key word here is “always”. Traffic signals do help prevent collisions, but since only 40% of collisions occur at intersections, and drivers often get into accidents by trying to beat a red light or disobeying traffic rules, the truth is that poorly timed signals will not eliminate human actions, and therefore, will not eliminate all accidents.

Nevertheless, optimizing traffic signals to mitigate traffic conflicts is in the best interest of everyone. Coordinating traffic signals can reduce driver frustration, cut down on the number of cars running red lights, and decrease the number of traffic accidents occurring at our intersections.

Bottom line:
Motorists form their own opinions based on urban myths about traffic signals and controls. Our job, as traffic experts, is to minimize the number of traffic aggravations experienced by motorists.

The ultimate goal is signal optimization for each and every thoroughfare – this can be accomplished through synchronized traffic signals, vehicle detection systems, and communication between intersections. Learn more about the latest technology used for traffic control at

Upper Dublin, PA board plans smart traffic lights

No comments

In other news, new traffic signal cameras are coming to the area that may make the wait at the light a lot shorter.

The board awarded a contract for the installation of a traffic signal adaptive system known as InSync to Republic ITS for $214,204.50.

The contract calls for the installation of four cameras at intersections in Dresher.

Township Manager Paul Leonard said the following intersections will see the cameras installed: Virginia and Susquehanna Road, Dreshertown Road and South Limekiln Pike, Dreshertown and North Limekiln Pike and Limekiln Pike and Susquehanna.

The camera installations will be paid for by an Automated Red Light Enforcement (ARLE) grant from PennDOT.

The board also approved the installation of a fifth camera at the corner of Virginia and Office Center drives. The original bid price for the installation was $38,700, but wiyj BET Investments and Wawa, scheduled to open at the corner, eaching donating $10,000 to implement the system, the total cost to the township will be $18,700.

Leonard said the project will install five smart traffic signals throughout the area to help move traffic more efficiently. The InSync system uses video cameras not to enforce traffic but to adapt to traffic conditions and adjust the lights accordingly. The cameras don’t take pictures of motorists trying to catch a light; they only work to reduce the wait time for cars at a red light.

Leonard said the installation will be a “dramatic improvement” because “motorists that use these traffic signals will pretty quickly figure out that the traffic signals are a little more on their side” because the signal will know how many cars are waiting and will adjust.

He said if the signals were to break, they would default to their original settings and people would notice the difference.

The software used in the InSync software is not just a time system. Instead, the camera actually counts each car waiting at the light and forwards the information to the next light ahead, allowing it to adjust before the cars even get there, to make sure all the cars keep moving.

“When a mechanical device is on your side, you know it. When it’s not, you really know it,” he said, noting studies have shown a 60 percent decrease in wait time when these devices are installed.

InSync adaptive signals help keep traffic moving in Greeley, CO

Greeley drivers may have noticed recently that traveling on U.S. 34 Business (10th Street) between 23rd Avenue and 59th Avenue has been a bit easier of late. Yet no highways were uprooted, no lanes were added, and nothing really seemed to change. Curious how this is possible? Let us introduce you to adaptive traffic signals.

This past April, the Colorado Department of Transportation and the city of Greeley installed a new adaptive traffic system after years of trying to efficiently time this complicated corridor. We tried a new technology since we didn’t have the means to reconstruct the roadway, and we wanted to improve the traffic flow and ease traffic for commuters who spent roughly 10 minutes going through this stretch of highway, usually stopping several times along the way. As part of the joint effort, state and federal dollars were used, as well as hundreds of man hours provided by city staff in lieu of city of Greeley funding.

Here’s how the technology works: The adaptive traffic signals [InSync from Rhythm Engineering -RE] use real-time data collected by sensors to create a “green tunnel” for drivers moving through the corridor. Unlike traditional signal timing systems which set a predetermined pace for the flow of traffic, this new technology allows signals to communicate with each other by notifying each other of approaching traffic so lights turn green before motorists arrive at the intersection. As you have driven down US 34 Business, you have probably noticed that you get stopped at fewer red lights and you are able to travel at a more constant rate of speed.

The adaptive traffic signal control system has already proven to have many benefits for the city of Greeley as a whole, as well as for individual motorists. Individual drivers have experienced a decrease in the amount of time it takes them to drive through the corridor, having gone from a 10 minute drive to between an eight and five minute drive, have been stopped half as often during optimal conditions, have experienced faster speeds through the area, and have saved 4 percent on fuel consumption. The city has benefited from the smoother traffic flows, fewer emissions put into the air, potentially fewer accidents, and with the annual savings expected to be $1.3 million a year, the system pays for itself in a matter of months.

As Greeley continues to grow and develop into an important economic hub in northern Colorado, this cutting-edge traffic signal technology will hopefully make life a little easier for citizens who commute via 10th Street every day, the students who study nearby, and visitors who want to explore what Greeley has to offer.

Upper Merion, PA Recognized for DeKalb Pike Traffic Improvements

No comments

August 3, 2012 – King of Prussia Courier

UPPER MERION, PA – The township received the first-place award in the 30th annual Road and Bridge Safety Improvement Contest, presented at the 90th annual Educational Conference of the Pennsylvania State Association of Township Supervisors in Hershey May 6-9. The conference attracted attendees from every county in Pennsylvania except Philadelphia, which has no townships. Upper Merion Township won the award for an adaptive traffic signal system along DeKalb Pike.

The township association sponsors the statewide Road and Bridge Safety Improvement Contest each year in partnership with the Pennsylvania Highway Information Association and the state Department of Transportation to recognize townships for their extensive contributions of time and effort in making roads and bridges safer.

The Upper Merion Township project involved the implementation of the first functioning adaptive traffic signal system in Pennsylvania, which uses video detection to measure the volume and delay of traffic at intersection approaches and then determines the appropriate signal phase and green light time for each phase to minimize delays at the intersection. [The township installed InSync from Rhythm Engineering. -RE]

The township first installed the adaptive traffic control system in 2010 at the intersections of DeKalb Pike with Gulph Road and Mall Boulevard. These locations were selected because of the fluctuating traffic volumes in this highly developed area, which includes the King of Prussia Mall; hundreds of homes; numerous hotels, office buildings, retail centers, and restaurants; and a convention center. The average daily traffic volume for DeKalb Pike is 40,000 to 50,000 vehicles per day.

Based on the success of the initial project, the township secured a grant in 2011 from PennDOT through the Automated Red Light Enforcement Program to expand the system along the remainder of the DeKalb Pike corridor. This phase included the installation of the adaptive traffic signal system at eight intersections and the addition of striping and signage at two intersections to improve safety.

Upper Merion Township’s traffic signal division, which includes three employees with International Municipal Signals Association certification, has one of the most proactive signal maintenance programs in the area. Consequently, the township was able to maximize the grant funds by using its own staff to complete the installation of the video detection cameras and wiring and make the modifications to the existing traffic signal control cabinets to install the adaptive components.

As a result of the system’s installation, DeKalb Pike has seen reduced travel times during peak hours ranging from 10 to 44 percent, averaging about 25 percent. Delays have been reduced 13 to 53 percent, averaging 32 percent. The system has also reduced vehicular stacking in left-turn lanes and on side streets along the corridor.

Upper Merion Township manager Ron Wagenmann says that at the intersection of DeKalb Pike with Gulph Road, the busiest in the township, the new system has resulted in a 40 percent improvement in peak-hour throughput, or the number of vehicles that pass through the intersection in the specified time.

“The adaptive system is truly automated,” he says. “It measures not only the volume of traffic but also the density and then alters the phasing of lights to get the best improvement in traffic flow.”

Public comments on the traffic signal system revealed frustration at first because drivers could no longer anticipate the timing of the lights and, perhaps, “cheat” a little, Wagenmann says. “Once people got used to it and saw how it reduced congestion, we got a lot of positive feedback,” he says.

Receiving the Road and Bridge Safety Improvement Award was just icing on the cake.

“We are very pleased to receive the award because it recognizes our effort to do what we can to improve safety for our residents and nonresidents,” Wagenmann says.
