Purdue Software Rolls Out Toolkit for Law Enforcement, First-Responders

Sep 27, 2013 (Close-Up Media via COMTEX) -- Purdue University researchers have developed a new tool for law enforcement officers and disaster assistance first-responders to reduce crime and assist people.

According to a release, the tool is called the Visual Analytics Law Enforcement Toolkit, or VALET.

The university reported that the toolkit software, developed at Purdue's Homeland Security Center of Excellence, provides real-time data so officers can analyze high-volume criminal, traffic and civil incident data as well as related emergency management and disaster preparedness events so they can be more strategic in how they allocate resources in their communities.

"One of my sayings is, 'We need to work smarter, not harder,' and the VALET toolkit allows us to pull data so we are in a better position to put officers in the right place at the right time when a situation arises," said John K. Cox, Purdue University chief of police. "Providing this type of situational awareness gives us the higher level of assessment so we can better cover high-crime areas or give officers context of what is happening so they know what they are walking into when on patrol or responding to a call." Additionally, according to a statistical analysis based on historical data, the software program includes temporal prediction algorithms to forecast future criminal, traffic and civil incident levels within a 95 percent confidence interval, meaning the estimates of the collected data could be reliably repeated and used to predict future behaviors or actions.

The VALET software can be used on most computers, and its companion software, called iVALET, has been designed specifically for the iPhone and iPad.


Law enforcement agencies can receive trial versions of the software packages through Purdue's Visual Analytics for Command, Control and Interoperability Environments, or VACCINE.

"Predictive and proactive analytics that creates a picture of what is happening at any given time and what could happen in an hour or a day or a week is a tremendous help for law enforcement and disaster relief officials," said David Ebert, director of Purdue's Visual Analytics for Command, Control and Interoperability Environments, which is a U.S. Homeland Security Center of Excellence.

The technology enables law enforcement agencies to interactively visualize and analyze their datasets in linked geospatial or mapping and temporal views of time graphs, calendars and clock views.

Collaborators in the development of VALET include the Purdue University and West Lafayette police departments, Tippecanoe County Sheriff's Office and the Ohio State Highway Patrol. The U.S. Department of Homeland Security, Command, Control and Interoperability Center of Excellence at Purdue University provided funding for the project.

Purdue University's other patented technologies include new cancer treatments, alternative fuels, biomedical devices, agriculture innovations and others that are available for licensing through the Office of Technology Commercialization.
