With map-based computer aided dispatch (CAD) systems, dispatchers in public safety agencies ensure patrol effectively covers an entire area – not just criminal hotspots. The Greenbelt Police Dept. in Maryland uses this technology to keep their community safe.

Increasing patrol in areas of high crime is nothing new for most jurisdictions.
According to CAD Manager Mike Dewey of the Greenbelt Police Department, patrolling crime hotspots is a priority. Ensuring other areas of the city are also covered efficiently is something they do as well through the use of their mapping software.
Dewey said he monitors patrol patterns in real time, which helps to identify areas of high saturation. High saturation can indicate areas known for higher crime rates, which leads to an increase of patrol. It can also show where several police cars are following a response to a call for service.
Being able to identify these areas empowers everyone from supervisors to dispatchers to officers in the field to see where each police unit is located.
From there, officers have the ability to move from areas of high saturation to areas of lighter coverage. This maximizes the police department's coverage of the entire city and provides effective coverage for a community.
"Using the software to watch where officers have been recently allows the shift to function as more of a coordinated unit," Dewey said. "Without this ability, it is much more likely that areas in the community would inadvertently get less efficient coverage."
The mapping capabilities of Greenbelt's public safety software also aids in faster response times. For instance, when a call comes in to the dispatch center but has not yet been assigned, officers in the field can see that the call has been queued up and can start driving in the direction where there is a need for service.
In taking this proactive measure, officers are en route faster and arrive on the scene quicker once the address is provided or units are assigned.
"The capabilities of our software system definitely result in faster response times," Dewey said.
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."
