On a typical day in the neighboring communities of Nederland, Port Neches, and Groves, Texas, three dispatch operators are responsible for answering and routing all 911 calls in the area – around 60 to 70 calls each day.
That all changed in the fall of 2017.
By August 30, 2017, Hurricane Harvey had shifted course in the Gulf of Mexico and unexpectedly poured 64.51 inches of rain on the communities, most of which came down in one day.
Fighting heavy rains and historic flooding, two additional operators were brought in to manage the call volume. Working night and day for five days, the dispatchers managed the more than 3,200 calls from residents in their communities and around the region.
This storm was Chief Paul Lemoine's fourth hurricane with the Port Neches Police Department, and, in his experience, communication has always been key to a successful operation.
His department faced the challenges of technology that couldn't keep up during previous storms. With no way to take outside calls because of failed communication systems, officers had previously been forced to rely on word-of-mouth communication, he said. In the past, flooding neighborhoods with volunteers and officers going door-to-door was necessary to ensure everyone got the help they needed.
But, not this time.
Throughout the weather event, dispatchers continually relayed pertinent information about people in need and physical road blocks to officers in the field using walkie talkies and cell phones.
"We all had houses that had flooded, and we were all actively doing water rescues for several hours at a time, and we were being inundated with rescue requests," Lemoine said. "We really relied on our dispatchers to relay that information to keep us from wasting time and continually moving forward. It was the middle of the night. We were up to our necks in water, getting in and out of boats, so it was really a lifesaver for us."
When the rain stopped, the sun finally reappeared, and the flooding started to recede, dispatchers helped direct officers to find and rescue more than 180 people. Empowered with timely, accurate information and a connection that lasted through the storm, no lives were lost and no officer was injured in the field.
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.
There are a few ways to dispatch emergency services when a call for service comes in to a call center.
Without computer aided dispatch (CAD) software, dispatchers send transmissions via radio to first responders. These first responders use pen and paper to record the information or commit the details to memory. To get to the scene, they might use their own mobile phone’s routing features, or rely on their own knowledge of the area.
Then there are dispatchers who utilize CAD software and send a response, but are unaware of the unit’s estimated time of arrival (ETA). Once the unit is dispatched to a call for service, dispatchers calculate the ETA based on the unit’s location, speed and route.
What dispatchers and law enforcement officers have learned is that a much more efficient way to get to the scene is through proximity dispatching. With this method, dispatchers see where police, fire and EMS units are on a digital map in CAD software in real-time along with their continuously adjusting ETAs.
The continuously updated ETAs that proximity dispatching relies on are provided through the use of automatic vehicle location (AVL) functionality. This provides the most accurate information possible, so that dispatchers and first responders can see where all units are by looking at their digital maps either in the CAD mapping system or mobile data terminals in patrol cars, fire engines, or other emergency vehicles. Using this information, dispatchers determine which unit should be dispatched to ensure the quickest response.
AVL works by having each emergency vehicle equipped with global positioning system (GPS) functionality. By pre-programming GPS data into an agency’s mobile server, the mobile software located in police, fire and EMS vehicles communicates seamlessly back and forth to dispatch.
This same signal is sent to other units within the agency, all of which are able to view this information using the maps on their mobile devices.
AVL technology continuously sends latitude and longitude coordinates back to the CAD system so that dispatchers always know the location of a unit.
