Next Generation 911 (NG 9-1-1) is a hot topic for public safety agencies across the United States.
This initiative, which was set forth by the National Emergency Number Association (NENA), is aimed at updating 9-1-1 services to accommodate a growing wireless society. It consists of numerous stages, all of which should be completed by 2020.
Until that time, public safety answering points (PSAPs) across the country will be preparing to adhere to guidelines set forth by NENA so they will have the ability to handle modern, mixed media messages from the public.
Text-to-911 is one of the first steps many PSAPs are undertaking along the NG 9-1-1 journey. As TTY (text telephone) services are phased out, the deaf and hearing impaired community will need a way to communicate with emergency services. Text-to-911 will replace TTY services, so it is imperative all PSAPs throughout the country are able to receive, handle and respond to these messages.
As of late 2016, less than 15 percent of PSAPs in the U.S. have the ability to accept text messages.
However, many PSAPs throughout the country are readying themselves for NG 9-1-1 and its various phases so they are prepared when all guidelines are established.
Once all guidelines are in place, PSAPs will have the direction to receive voice, text and data sent over IP networks from various communication devices.
In almost every town in the United States, there are areas that the locals know to avoid if they want to get someplace quickly.
These areas could involve one-way bridges, dirt roads that always wash out after a storm, shorter-than-average overpasses and other potential traffic hazards.
But people can’t always know every backroad in each community. This is especially true when it comes to emergency dispatching services.
Since no community is the same, it is important for computer aided dispatching (CAD) software and emergency 9-1-1 dispatchers using that software to also have solid geographic information system (GIS) data to support real-world scenarios that can impact routing.
Imagine leveraging GIS routing data such as one-ways, speed limits, travel time, max height and weight, and anything else specific to a community right within the CAD software. This would ensure a faster, data-driven response and avoid potential traffic hazards that could delay a response.
For instance, CAD software with the ability to take a community’s unique GIS data into consideration would prevent a ladder truck from being routed over a town’s old wooden bridge with a weight restriction or low overhang.
Using this data, dispatchers would be able to route vehicles to a call for service without ever having to worry about the emergency vehicle encountering a scenario that could delay service.
A community’s unique GIS data helps dispatchers to always send the fastest, smartest response.

The manner by which the world communicates via phone has changed.
Recognizing this change, the National Emergency Number Association (NENA) developed Next Generation 911 (NG 9-1-1).
NG 9-1-1 is an initiative aimed at updating 9-1-1 emergency services to accommodate a growing wireless society and provide individuals with additional ways to reach out for emergency services. It allows for the public to communicate with 9-1-1 emergency services the same way most people communicate with each other today using text and multi-media messages on mobile phones.
In 2000, NENA first began to address the shift in how individuals communicate via phone and the need for the public to be able to talk to 9-1-1 emergency services in different ways. By 2003, NENA started to create standards for what NG 9-1-1 really meant.
The goal with NENA's initiative was to provide guidelines for public safety answering points (PSAPs), which would define requirements for PSAPs to follow. However, as of 2016, these requirements have not been fully defined.
Many PSAPs are preparing for NG 9-1-1 requirements by updating technology to enable the acceptance of voice, video, text and data sent over IP networks from various communication devices.
Communicating with 9-1-1 services using NG 9-1-1 technology will work the same way communication via smartphones does now for personal usage. However, instead of sending messages between friends, family, coworkers and the like, messages will be exchanged between the general public and emergency text call takers.
The goal of this technology is to make sure individuals can communicate with 9-1-1 services in a variety of ways. It is the goal of NENA to make sure public safety agencies have guidelines and standards to follow when adaptation of this technology becomes mandatory.

When a 9-1-1 hang up call comes into a dispatch center, call takers immediately call back to determine whether help is needed or not. But when dispatchers call back and don't get an answer, they know there could be a problem.
When dispatch personnel with the Greenbelt Police Department received a 9-1-1 hang up call in early 2016, they immediately called back and were connected to a fax machine.
Dispatch searched the number in their computer aided dispatch (CAD) system and was able to come up with an address associated with the number so that an officer could head out to the location. The first officer routed to the location quickly investigated the situation and individual on the scene.
According to CAD Manager Mike Dewey of the Greenbelt Police Department, that officer on the scene immediately identified that the individual at the apartment was possibly undergoing some kind of mental health issue or under the influence of drugs.
While on the scene, the officer accessed premise history through his mobile data terminal in his patrol car and was able to see that a known Phencyclidine (PCP) user lived on the premises.
"PCP is a hallucinogenic drug that has a tendency to cause violent outbursts," Dewey said. "PCP can be an extremely dangerous addition to any call for service, and in this scenario, the lone officer was able to back out of the environment and call for sufficient additional resources."
According to Dewey, without the data sharing between the records and mobile solutions in the police department's public safety software to provide instant prior history information, this situation could have been dangerous for the officer and the individual who made the 9-1-1 call.
Instead, additional units responded to help the officer, which ensured there was no injury to the officers or the individual under the influence of drugs.
"Without enough officers to effectively handle the scene, you risk injury to everyone involved," Dewey said. "Our software helps us prevent these situations from happening."
A lot can change in less than a minute.
For an officer with the El Cajon Police Department, there was a lot riding on that small unit of time.
The officer had radioed in to dispatch and all he could say was that he had been hit. The call taker had no way of knowing if that meant he had been involved in a collision or shot.
Sue said in less than a minute, the call taker had identified the officer's location using the Automatic Vehicle Location (AVL) functionality of their Computer Aided Dispatch software. With this information, dispatchers were able to send a rescue response to the officer.
What they discovered upon arrival was that the officer had been involved in a collision. While stopped at a traffic light, the officer's vehicle was rear-ended by another vehicle traveling at 35 mph.
The officer suffered a broken neck, but had made a full recovery. The driver of the other vehicle was uninjured.
"This case serves as a prime example of how great the software is," Sue said. "We were able to get to his location even when he was unable to speak. AVL is a life-saving tool."
The Pacific Northwest is no stranger to strong storms, but some can be more destructive than others.
For 9-1-1 dispatchers in Snohomish County, these storms have the potential to intensify call volumes – and that's exactly what happened in November 2015.
The storm generated winds as high as 119 mph, leaving more than 1 million individuals without power throughout the region. These winds caused significant structural damage to buildings and homes and also resulted in several downed trees. Three individuals in the greater Seattle area were killed as a result of falling trees.
Because of the damage to private residences and injuries this storm caused, numerous calls came in to the Snohomish County Police Staff and Auxiliary Server Center (SNOPAC) and the Southwest Snohomish County Communications Agency (SNOCOM), the county's two Public Safety Answering Points (PSAPs).
As if the storm itself wasn't bad enough, both PSAPs lost power and ran solely on their generators throughout the duration of the storm.
According to SNOPAC's executive director Kurt Mills, SNOPAC nearly doubled its 911 call-takers during the storm to keep up with the calls coming into the center. In spite of the intense call volume, the system never faltered, which was a concern Mills had due to the fact that the PSAP had only been using its new computer aided dispatch (CAD) software for a few weeks at that point.
"The storm was massive," Mills said. "We are already a busy center processing around 1,300 calls every day, but during the storm we really pushed our new CAD system hard with a flood of calls and activity and it handled the workload without as much as a hiccup."
These storms helped illustrate just how far a solid CAD software solution and dedicated public safety staff will go to handle everyday emergencies and extreme situations.
"We're shaving seconds and sometimes minutes off of every mutual aid response, which often happen numerous times every single day, by not having to call our sister PSAP and ask for units," Mills said.

Dispatchers at SNOCOM (Southwest Snohomish County Communications Agency) know that when it comes to emergency calls, time is of the essence. A call that came in early 2016 highlights this fact.
According to SNOCOM Operations Manager Andie Hanson, that early 2016 call was in regards to a man who was unresponsive. To provide help for this urgent situation, the dispatcher was able to use latitude and longitude coordinates generated from the cell phone the caller was using to get first responders on the road.
While these coordinates did not give the street address, it helped ensure a speedy response for the unresponsive man. Once the exact address was given, units were able to be there within three minutes of when the call came in.
"In situations that escalate so quickly, it's imperative that we have the ability to reach the citizens of our county as quickly as possible," Hanson said.
While SNOCOM always had the ability to dispatch first responders to emergencies, this process is more efficient now with the use of their new computer aided dispatch (CAD) software. This software helps dispatchers to communicate with agencies throughout the county regardless of jurisdictional lines.
Hanson said this borderless communication helps reduce the impact of call transfers, increases collaboration, and makes information sharing both immediate and easy. In addition, the easy access to data helps officers in the field to stay safer, as dispatch is able to provide them with real-time information regarding any call they respond to.
In regards to the comatose man, Hanson said that if SNOCOM had been using their old CAD system, help would have arrived later, and those minutes could have added up to a different outcome.
"The real-time information that we have now and the dynamic unit recommendation features of our CAD software helps us to not only protect the public, but to protect officers as well," Hanson said.
