New Book from Our CEO

Shades of Green Book

In 2012, Dr. Chandra released his first book, Shades of Green: Why Traffic Signals Frustrate You and What You Can Do to Fix Them. This book, written for motorists, elected officials and others new to the traffic world, explains in easy-to-understand terms the sometimes complex workings of traffic control equipment. Readers will learn:

• Why traffic signals don’t seem to work correctly
• The safest speed to drive
• How to fix those traffic signals that often cause frustration
• The benefits of synchronizing traffic signals.

The Traffic Crisis

Bad traffic is more than a nuisance; it’s a costly and deadly problem that steals time and money from families, poisons the air we breathe and needlessly claims thousands of lives. Traffic’s cost to society in terms of lives, dollars and health has reached the crisis stage. It’s time to deliver a higher standard in traffic management and safety.

30,000 Traffic Fatalities Each Year

30,000 Traffic Fatalities Each YearIn the U.S., more than 30,000 people die in traffic accidents each year. Intersections are the site of 40% of crashes and 20% of fatalities.

$101 Billion: The Cost of Congestion

$101 Billion: The Cost of CongestionThe cost of congestion in the U.S. is $101 billion per year or more than $700 for every auto commuter. This figure takes into account 4.8 billion hours of wasted time and nearly 2 billion extra gallons of fuel.

$4/Gallon and Rising

$4/Gallon and RisingThe days of less than $2/gallon gas in the U.S. are long gone, and upwards of $4 is the new normal. As fuel costs continue to rise, families and businesses feel the pressure.

80 Billion Tons of Toxic Emissions

80 Billion Tons of Toxic EmissionsBurning nearly 2 billion gallons of nonrenewable fossil fuels due to traffic congestion means we’re filling the air with unnecessary harmful emissions – 80,593,762,135 tons of pollutants.

6 out of 10 Americans Breathe Unsafe Air

6 out of 10 Americans Breathe Unsafe AirToxic emissions poison our respiratory systems. Now, 6 out of 10 Americans live in areas with unhealthy levels of air pollution. An estimated 50,000 to 100,000 Americans die every year from outdoor air pollution, largely due to lung and cardiovascular diseases.


The Inadequacy of Current Approaches

When the culprit for wasted time and fuel is poor signal timing, more can be done to keep traffic moving. Yet both the methodology and the technology currently employed for signal coordination are inadequate.

Traffic Signal Coordination Gets a “D+”

Traffic Signal Coordination Gets a “D+”The 2012 National Traffic Signal Report Card gives a grade of 69 or D+ to the overall management of traffic signals in the U.S. This result indicates that improvement and investment in traffic signal operations remains critical.

Timing Plans Are Inherently Inflexible

Timing Plans Are Inherently InflexibleThe labor-intensive process of collecting sample data to create coordinated timing plans is imprecise and limited in its effectiveness. In many cases, upwards of 5-7 years (or more) of signal coordination is based on one 6-10 hour sample of traffic. Even the best, most up-to-date plans cannot respond to random fluctuations in traffic such as before and after special events.

New Shiny Exterior, Old Thinking Inside

New Shiny Exterior, Old Thinking InsideThe latest traffic controllers use digital hardware, but at their core they are constrained by analog concepts such as fixed offsets, common cycle lengths and standardized allotment of green time, or splits. By emulating old-fashioned thinking, these controllers are unable to quickly serve the phases or movements that best accommodate actual demand. The technology is simply not sophisticated enough to move traffic as efficiently as possible.

Cutting-Edge Research Not Accessible

Cutting-Edge Research Not AccessibleMany universities are pursuing an academic approach to improved signal timing and coordination. While these projects may have potential, current research coming out is either years away from deployment or unaffordable for the average community. These research projects are often geared toward major metropolitan areas that can spend $10 million on a traffic project. Here at Rhythm Engineering, we believe traffic matters everywhere—not just in big cities—so solutions must be accessible to all.

These twin problems of traffic congestion and the lack of robust, intelligent tools to deal with traffic are overwhelming when considered together. To dramatically improve traffic and reduce its many negative side-effects, we took a radically new approach to traffic signal coordination. It’s no surprise then, that we’re achieving radically new results.

Our Story

Dr. Reggie Chandra, P.E., P.T.O.E. is the traffic engineer-entrepreneur who invented InSync. His rare combination of education and experience put him in a unique position: he was rooted enough to be a traffic industry insider familiar with the tools and challenges of the trade, yet visionary enough to move beyond accepted methodologies. Dr. Chandra imagined a better, more intelligent way of managing traffic. More importantly, he brought that idea to life. Having spent a large portion of his career Dr. Reggie Chandra, P.E., P.T.O.E.as a public traffic engineer focused on optimizing and synchronizing signals, Dr. Chandra grew frustrated with the tools available for him to perform his job. He knew the technology had fallen decades behind, yielding crowded roadways, smog, and wasted time and fuel. He also knew traffic engineers alone didn’t have the answers. In 2005, he set out to find a solution entrepreneurially by assembling a team of computer scientists and mathematicians uninhibited by traffic engineers’ preconceived limitations. They developed a vehicle-counting camera that laid the groundwork for what Chandra had envisioned since the 1990s. In February of 2008, the team flipped the switch on an artificially-intelligent, digital system that optimizes signals to automatically adapt to traffic conditions in real time. As a result, he revolutionized the traffic industry.

InSync’s Nationwide Growth

Since its launch, InSync has become one of the top selling adaptive traffic control systems in the United States. More U.S. traffic agencies select InSync than any other adaptive traffic control system, making it the fastest growing such system in U.S. history. As of January 2014, InSync is the solution of choice for more than 1,000 intersections in 25 states.

What Makes Rhythm Engineering Different

Rhythm Engineering is unique among adaptive traffic control providers in that it works directly with municipal, county and state transportation agency clients through every step of the adaptive traffic control deployment process, from product conception and design to project installation and support. Rhythm Engineering:

  • designs and develops its own hardware and software components,
  • procures and tests its InSync Processors and other equipment according to a rigorous quality management system,
  • engineers and custom-configures the InSync system for each unique corridor and community,
  • trains clients and contractors in-person on the complete installation, integration and adaptive implementation process and
  • provides nationally-acclaimed 24/7 technical support on every InSync-outfitted intersection and corridor in operation.
