Purdue University researchers have de- veloped a visual analytics tool that can give police and emergency responders a real-time view of a location, layered with crime, traf c, geospatial, weather and other data. The goal, researchers say, is to give law enforcement agen- cies predictive, and well as responsive, capabilities. Called the Visual Analytics Law Enforcement Toolkit, or VALET, it al- lows of cers to analyze high-volume criminal data with the surrounding context, such as traf c conditions, civil incident data and any related emer- gency management events, according to the project leaders. It also can layer in weather information, zoning tracks, census and demographic data -- and even the moon phase. The tool has a variety of potential uses. It could be used at headquar- ters to plan regular routes based on crime rates and the times of the day or week crimes are most likely to occur, even factoring in weather forecasts or scheduled major events that could gum up roads. The researchers say VALET's statistical analysis of his- torical data and temporal prediction algorithms can forecast future criminal, traf c and civil incident levels with 95 percent con dence. It also would be effective in managing the response to a major incident, where outside factors could affect the response. Aside from HQ, it's also available to of cers in patrol cars, who can access it via their on-board laptops. And a mobile version, iVALET, works with iPhones and iPads for of cers who are on foot. "Providing this type of situational awareness gives us the higher level of assessment so we can better cover high-crime areas or give of cers context of what is happening so they know what they are walking into when on patrol or responding to a call," said John K. Cox, Purdue University chief of police. VALET was developed at Purdue's Homeland Security Center of Excel- lence in cooperation with university police, the West Lafayette PD, the Tippecanoe County Sheriff's Of ce and the Ohio State Highway Patrol. A sample screen might include a map of a selected location surrounded by a line graf, calendar view, clock view and crime history, with a time slider that ties the data together so, for example, crime reports can be viewed over a selected time. The screen also includes a Twitter widget that could help detect unusual activity, such as a protest or riot. • Police take visual analytics on patrol BY KEVIN McCANEY IT managers' biggest worry isn't cyber Cybersecurity is always a concern, but the biggest The biggest source of trepidation about government IT infrastructure are budget constraints, according to the recent Cisco Connected Government Study, which polled 400 federal, state and local IT managers about threats, funding and their familiarity with emerging technologies. Budget concerns were especially felt among state and local respondents, the survey report said. But security is never far from managers' minds---in fact, 71 percent said they'd rather be stuck in a elevator for 24 hours than have their networks hacked. Respondents said technology is the most effective way to strengthen the nation's cybersecurity posture and that cybersecuri- ty is still the top area they want to invest in.
