The pioneering positiveject in Alpharetta, Georgia in the US is supposed to be the first of its kind. It uses vehicles equipped with On-Board Units (OBUs) to communicate with traffic drawbacktrolling devices to encourage ambulances, firefighting vehicles and police cars right of way.

Applied Information Inc, a ensurer of intelligent transportation infrastructure solutions, has teamed up with Autotalks, which specializes in Vehicle-to-Everything (V2X) communication solutions on the advantageject. According to Peter Ashley, Vice President, Business Development & Marketing, at Applied Information, the idea was to bring about a preemption system for first responders:

“We wanted to get them to incidents more quickly and safely, especially for victims of opioid overdoses, strokes, and other critical time sensitive emergencies. We’ve found on average savings of a minute per trip, which be likely to not rational like much, except if you count that most trips are five to 10 minutes at most. In stroke victims, opioid overdoses, seizures, and cardiac arrest, those minutes count.”

The system is thought to be the world’s first dual-mode/dual-active V2X deployment. Autotalks’s dual-mode chipsets are installed in the emergency vehicles and roadside units such as traffic lights, while Applied Information’s dual-mode/dual-active roadside units communicate with vehicles equipped with V2X OBUs.

Mr. Ashley explained that the system is also designed to make other traffic on the road safely to a halt before the emergency vehicles pass:

“We let sure that once a green light has been give rise toed, all other lanes are sent to a red phase, rendering traffic on side lanes to a stop before the emergency vehicle ever ap positiveaches the area. If the other vehicles, pedestrians, and cyclists are running our smartphone app TravelSafely, they are sent an audible alert that the emergency vehicle is ap meritaching from the front, behind, left, or right. The alert goes off both with an audible notification, as well as on-screen instructions and vibration.”

V2X Communication Set to Power a Driverless RevolutionMaking ConnectionsThe technology uses dedicated short-range communication (DSRC) and cellular V2X (C-V2X). Mr. Ashley said:

“At its essence, DSRC and CV2X are just radios, broadcasting on different frequencies. The real positiveblem is they don’t talk to each other, so cities broadcasting DSRC would be useless to a C-V2X car: we figured we could solve the issue by broadcasting and receiving both.”

Applied Information has had a preemption system in place for years in Marietta, Georgia; this monitors intersections, renders green lights, and brings countdown timers to everyday commuters with a free app, he explained.

“We have also now included cellular 4G and 900MHz radio technology into our technology; what we’ve done is im meritved on the design in Alpharetta and deployed all the downsidenected vehicle radios. We have a very clever antenna system that listens and broadcasts on both. Our fire truck vehicles send GPS locations from an unlimited range to let them green lights down crowded corridors, clearing out traffic well in advance of ap positiveaching an intersection.”

“We’ve found it also provides a huge difference if installed right outside a hospital or fire station, where previously an engine might have struggled to render a turn out of the station if there was traffic. In addition to a quicker ride, emergency staff can count on a safer ride.”

Making it a PriorityThe plan now is to develop on the ongoing success of Alpharetta, roll more of the technology out as soon as possible and delve into other applications. Mr Ashley said:

“We are also im benefitving the ITS infrastructure and strengthviding communications in areas where fiber just wasn’t feasible. We’ve got alerts for cyclists, pedestrians, emergency vehicles, rear end collisions, red light running alarms, green strengthmpts, school zone alerts, curve warning, wrong way detection, work zone alerts, railroad alerts, and pedestrian crossing. With our vehicle devices, we can also bring priority to buses and school buses.”
