The dawn of smart cities is upon us, using the internet of things to solve both big and little problems. In Georgia, Texas, and Hawaii, a new technology is being used that will ease traffic woes for public safety vehicles.

The technology uses dual mode chipsets by Israel-based Autotalks that are installed in roadside units, such as traffic control boxes. Autotalks has teamed up with Applied Information Inc., an Alpharetta, Georgia-based provider of intelligent transportation infrastructure solutions, to provide traffic signal preemption technology that helps emergency vehicles reach their destination safely and quickly.

Traditionally, emergency vehicles travel through traffic with their lights or siren, or a combination of both, activated when on the way to a call. When they near an intersection, drivers must navigate the traffic signals, pedestrians, vehicles, and any road hazards, often times while at speed, all while receiving evolving information about the situation they are approaching.

In 1914, American Traffic Signal Company installed the first traffic light that could be used by police and fire personnel to control the signals in the event of an emergency. Over the last century, the traffic signal preemption technology has evolved, offering acoustic, line of sight, localized radio signal, and GPS technology.

Generations of drivers grew up seeing Rad-O-Lites by the now-defunct Relco Emergency Light Company out of Erie, Pennsylvania, flashing white signals on the same line next to traffic lights alerting them to the presence of a nearby emergency vehicle that was responding to a call.

The new technology being implemented was developed and allows emergency vehicles equipped with the units to initiate traffic signal control measures. While the technology's main use case is in emergency vehicle traffic signal preemption, it can also be used by transit buses for traffic signal priority and vehicles involved in roadside work zones.

The City of Alpharetta, Georgia, was the first in the U.S. to deploy the company's technology. According to a spokesperson for the Alpharetta Department of Public Safety, the RSUs are featured on all traffic signals controlled by the city — approximately 150 units.

In Harris County, Texas, the chips are used in over 500 School Beacon Flasher Timers.

"The AI/Autotalks solution enables roadway operators to confidently deploy V2X technology today so the infrastructure is ready for the auto industry deployment, while providing 'Day One' benefits such as safer, faster emergency vehicle response times now," says Bryan Mulligan, president of Applied Information.

Houston researcher builds radar to make self-driving cars safer

eyes on the road

A Rice University researcher is giving autonomous vehicles an “extra set of eyes.”

Current autonomous vehicles (AVs) can have an incomplete view of their surroundings, and challenges like pedestrian movement, low-light conditions and adverse weather only compound these visibility limitations.

Kun Woo Cho, a postdoctoral researcher in the lab of Rice professor of electrical and computer engineering Ashutosh Sabharwal, has developed EyeDAR to help address such issues and enhance the vehicles’ sensing accuracy. Her research was supported in part by the National Science Foundation.

The EyeDAR is an orange-sized, low-power, millimeter-wave radar that could be placed at streetlights and intersections. Its design was inspired by that of the human eye. Researchers envision that the low-cost sensors could help ensure that AVs always pick up on emergent obstacles, even when the vehicles are not within proper range for their onboard sensors and when visibility is limited.

“Current automotive sensor systems like cameras and lidar struggle with poor visibility such as you would encounter due to rain or fog or in low-lighting conditions,” Cho said in a news release. “Radar, on the other hand, operates reliably in all weather and lighting conditions and can even see through obstacles.”

Signals from a typical radar system scatter when they encounter an obstacle. Some of the signal is reflected back to the source, but most of it is often lost. In the case of AVs, this means that "pedestrians emerging from behind large vehicles, cars creeping forward at intersections or cyclists approaching at odd angles can easily go unnoticed," according to Rice.

EyeDAR, however, works to capture lost radar reflections, determine their direction and report them back to the AV in a sequence of 0s and 1s.

“Like blinking Morse code,” Cho added. “EyeDAR is a talking sensor⎯it is a first instance of integrating radar sensing and communication functionality in a single design.”

After testing, EyeDAR was able to resolve target directions 200 times faster than conventional radar designs.

While EyeDAR currently targets risks associated with AVs, particularly in high-traffic urban areas, researchers also believe the technology behind it could complement artificial intelligence efforts and be integrated into robots, drones and wearable platforms.

“EyeDAR is an example of what I like to call ‘analog computing,’” Cho added in the release. “Over the past two decades, people have been focusing on the digital and software side of computation, and the analog, hardware side has been lagging behind. I want to explore this overlooked analog design space.”

12 winners named at CERAWeek clean tech pitch competition in Houston

top teams

Twelve teams from around the country, including several from Houston, took home top honors at this year's Energy Venture Day and Pitch Competition at CERAWeek.

The fast-paced event, held March 25, put on by Rice Alliance, Houston Energy Transition Initiative and TEX-E, invited 36 industry startups and five Texas-based student teams focused on driving efficiency and advancements in the energy transition to present 3.5-minute pitches before investors and industry partners during CERAWeek's Agora program.

The competition is a qualifying event for the Startup World Cup, where teams compete for a $1 million investment prize.

PolyJoule won in the Track C competition and was named the overall winner of the pitch event. The Boston-based company will go on to compete in the Startup World Cup held this fall in San Francisco.

PolyJoule was spun out of MIT and is developing conductive polymer battery technology for energy storage.

Rice University's Resonant Thermal Systems won the second-place prize and $15,000 in the student track, known as TEX-E. The team's STREED solution converts high-salinity water into fresh water while recovering valuable minerals.

Teams from the University of Texas won first and second place in the TEX-E competition, bringing home $25,000 and $10,000, respectively. The student winners were:

Companies that pitched in the three industry tracts competed for non-monetary awards. Here are the companies named "most-promising" by the judges:

Track A | Industrial Efficiency & Decarbonization

Track B | Advanced Manufacturing, Materials, & Other Advanced Technologies

  • First: Licube, based in Houston
  • Second: ZettaJoule, based in Houston and Maryland
  • Third: Oleo

Track C | Innovations for Traditional Energy, Electricity, & the Grid

The teams at this year's Energy Venture Day have collectively raised $707 million in funding, according to Rice. They represent six countries and 12 states. See the full list of companies and investor groups that participated here.
