Some key innovations in traffic control systems in the United States are Dedicated Short Range Communication units, V2V & V2I Technology, Smart traffic light technology, Smart streetlights, Wi-Fi enabled streetcars and digital kiosks. Kansas city implemented a combination of these technologies to build digitally connected infrastructures around the city. Below you will find a deep dive into our findings.
In the pursuit of finding the information on the recent innovations in traffic control systems in the United States, we explored the manufacturers of traffic light systems like Trafficvision, Flir, Sigfox, and Actility and several media sources like Forbes, NYTimes, Fortune, Mashable, and Globe Newswire. Through this strategy, however, we were able to get only the market size and growth trends, and there was no information related to the latest innovations in the sector. We then looked into the government portals like US data, Wyoming Department of Transportation, US Department of Transportation, etc. which again resulted in no significant new information.
Next, we searched for market research reports and magazine articles from sources like the zebra, State tech magazine, Seattletimes, Smart magazine, and Geotab. From this method, we gathered several trends and latest innovations around the traffic controls systems. Among the findings, we identified the key innovations by the number of citations in the above-mentioned sources. We chose the findings that are sufficiently referenced by fortune 500 companies like StateTech magazine, US government departments, and leading media firms.
Presented below is a brief description of each of the chosen innovations around the traffic controls systems in the United States.
#1 CITY OF COLUMBUS
Vehicle-to-vehicle (V2V) technology is the core of autonomous driving technology, where one vehicle collects information around it and communicates with another. In Vehicle-to-infrastructure (V2I) technology, the vehicle communicates with infrastructures like traffic signals and weather alert systems. In the city of Columbus, Ohio, the traffic signals gather information from government fleet vehicles to get an idea of the current traffic flow and modifies the signal timing with the changes in traffic throughout the day.
The city of Columbus is planning to add dedicated short-range communication units (DSRC) to traffic lights to convey a variety of safety messages like reduced speeds in school zones, increased pedestrian traffic, collision and traffic backup alerts to the connected vehicles. The city is aiming for 175 intersections along with onboard units in 3,000 vehicles. The DSRC network will support both V2V and V2I communications. The Traffic Management Center of Columbus provides the up-to-date information needed to monitor the roadways around and through the city.
Along with New York City and the Tampa-Hillsborough Expressway Authority, the U.S. Department of Transportation (USDOT) funded $45 million for Wyoming's CVP program. As part of the program, the Wyoming Department of Transportation (WYDOT) will install 75 DSRC units to highway infrastructure at critical points and 400 onboard units to state-operated trucks, highway patrol cruisers and snowplows, as well as vehicles owned by private fleets. The DSRC units communicate safety information to their connected vehicles and considerably improves the safety and efficiency of road travel.
The city of Tyler, Texas implemented smart traffic light technology and reduced traffic delays by 22%. Smart lights have sensors installed around the intersections that register the traffic volume throughout the day. Based on this data, the lights change in real time to ensure smooth flow of traffic. Following the example of Tyler, many cities are beginning to use smart traffic light technology.
#4 KANSAS CITY
Smart corridors, Smart street lights, Wi-Fi street cars, IOT sensors, Digital kiosks
Kansas City, with a goal of becoming the country's most digitally connected city, recently created a 2.2-mile smart corridor in its downtown. The project includes a Wi-Fi enabled streetcar that transports 6,600 people for free each day, smart streetlights that automatically dim if there are no people around it, digital kiosks that help people in finding parking spaces, and Internet of Things (IoT)-enabled sensors along the streetcar line that provides real-time traffic data to the public. The real-time information helps people to navigate downtown and reduces congestion.
#5 LAS VEGAS
With the help of Cisco’s cloud-based Smart + Connected Digital Platform Las Vegas is planning to aggregate and integrate information from sensors installed around the city to tackle a variety of urban issues like pedestrian and traffic safety. The platform helps in creating a smart city framework and provides a portfolio of solutions whether it’s streetlights or garbage cans.
To summarize, DSRC, V2V & V2I Technology, Smart traffic light technology, Smart streetlights, Wi-Fi enabled streetcars, and digital kiosks are some key innovations around traffic control systems in the United States. Many cities are planning to implement a combination of these technologies to tackle traffic congestion issues.
