Crimemapping Use in Transportation – Part 2
July 1, 2009
The British Transport Police have an innovative site that will show you where crime is occurring on the rail network at a local level across Britain. The police department’s objective is to keep the railway network is a safe and secure environment. They work closely with train operating companies using GIS to prevent crime and disorder and create an environment where passengers feel safe. Since 2005, reported crime on the railway network has reduced by more than 20 per cent.
It’s easy to find your local crime statistics. Just select your region on the map and use the local map to find your station, or use the search box and type in the station name. Choose the type of crime that you want to know more about and filter your search by total number of crimes or crimes per 100,000 passenger journeys. Select whether you want to view crimes recorded at the station or onboard a train. Onboard crime happens along the route of the train but is often reported at end of line stations meaning figures could be higher at those station locations.

Crimemapping Use in Transportation – Part 1
June 23, 2009
An article by Chief Mark W. Bowersox of the Polk City police department highlights how GIS can be used in preventing transportation problems in small cities. In 2003, the city of Polk City, Iowa had to prepare for the Allianz Golf Championship, a PGA Champions Tour event which was to be held in 2005. Polk City and its population of 3,000 needed to be ready for the 40 – 50,000 visitors expected during the week-long event. Handling the influx of visitors and traffic became an immediate concern especially to Polk City’s six-person police force. Fortunately, the chief and the city were in the process of installing GIS capabilities for citywide application. Through past contacts and with the use of aerial imagery and mapping capabilities, the city was able to put together a plan to handle the expected traffic demands of the tournament.
The police department believed that for the tournament to be well received by the community it needed to have a minimum effect on the daily routines of citizens. Maps were used to inform citizens and alleviate any anxieties they had during the months prior to the tournament. A Microsoft PowerPoint presentation was developed that featured aerial views of Polk City and included a map that illustrated potential problem areas if no traffic plan was used. A second map showed the same areas and how traffic-related problems would be minimized with the use of the traffic plan. The PowerPoint presentation was used numerous times at city meetings and informational meetings, where citizens were allowed to see the traffic plan and gain an understanding of how it was going to work.
Maps were used during the tournament as well. Several officers were brought in to help Polk City police provide security. Officers from other cities were given an aerial view of the golf course and its 6.5 miles of cart path. The maps helped the visiting officers orient themselves to the venue. The Polk City Fire Department also used the maps to assist medical personnel in responding to any calls for assistance. By using GIS, the Polk City police departments were able to see the golf tournament go off without a hitch.

West St. Paul Crime Prevention
June 18, 2009
The West St. Paul police department has made use of several strategies to help increase crime prevention. Among those strategies are, child car seat inspection, neighborhood watch, child safety tips, crime prevention tips, and a crime mapping database, all of which are made available to the public. TheCrime Map allow residents to view the locations and dates of crimes in the city that had accrued within the last 90 days. This map is updated weekly. Burglaries, robberies, arson, thefts, stolen vehicles and damage to property crimes are depicted by pushpins which are color coded to represent the particular type of crime.
The crime map does have a few drawbacks like police department business procedures dictating the timely display of recent crime data. Recording requirements may delay the availability of certain incidents on this map. Multiple incidents at a single location may not be apparent. Not all crime/call types are shown

Laws that restrict where registered sex offenders may live have become increasingly popular during the past decade. As of 2007, some 27 states and hundreds of municipalities had enacted laws that bar sex offenders from residing near schools, parks, playgrounds and day care centers. The specified distance from a school or other venue is typically 1,000 feet but varies from 500 to 2,500 feet, depending on the jurisdiction. Studies show that restrictions can create exclusion zones that make it difficult, if not impossible, for sex offenders to find housing. Sex offenders then may become homeless, go underground or report false addresses, making them difficult to track.
GIS analysis can help officials gauge the impacts of sex offender residency laws. By analyzing mapping data from GIS, they can isolate the exclusion zones and the areas available for housing in their communities. They can also determine whether registered sex offenders are living in compliant housing. Researchers mapped data from three areas using GIS to locate registered offenders and identify restricted sites and their exclusion zones. Various studies were conducted in Ohio, San Diego, California, and several municipalities in New Jersey. Although the localities differed in geography and population, all evidenced limited access to suitable housing.
GIS mapping can inform legislators about sexual offender residency requirements — especially in jurisdictions that are contemplating enactment of residency laws. Local officials can use the mapping analysis to determine whether affordable housing is available within approved areas and to evaluate the proximity of that housing to treatment facilities. Such prior analysis can demonstrate whether a proposed law is feasible to enforce. Jurisdictions with a residency law already in place can use the data to assess whether the exclusion zones result in a lack of housing options for offenders.

GIS Fights Crime in Chicago
May 26, 2009
Chicago’s homicide rates led the nation in 2003, so the Chicago police department (CPD) knew they had to find new methods to target crime. In an effort to help prevent murders and aggravated battery with firearms, the CPDs Deployment Operations Center deployed GIS (geographic information system) technologies to present crime information in geographic context. The point of using GIS technologies is to allow officers to make better-informed decisions about which areas of the city need additional police power.
Immediately, the department began seeing results. In the second half of 2003—the first six months of GIS deployment—the CPD saw an 18 percent drop in murders compared with the same period the year before. And then in 2004, Chicago had 23 fewer homicides compared with the same period last year.
In addition to helping the CPD target crime more efficiently, GIS is also saving the department time and money. Before deploying GIS technologies, the CPD used a client/server application developed in-house that enabled police officers to associate crimes with property information. While that application provided officers with information as they investigated crimes, keeping the data up-to-date was tedious because the application had to be loaded onto each computer individually, and new data had to be added every few weeks. With roughly 400 PCs, keeping up with that task was pretty cumbersome.

The New York Times posted an interesting though somewhat macabre article on the multitude of homicides that occurred in New York between 2003 and 2005. During that time period, 1,662 murders were committed in New York. Men and boys were responsible for 93 percent of the murders; their victims tended to be other men and boys; and in more than half the cases, the killer and victim knew each other. Interestingly, a small portion of the victim count includes those who had been stabbed, shot, or beaten and died as a result of their injuries a year or more after the incident occurred.
The GIS interactive map on the site allows the user to view the murders by borough and year. In addition, each dot on the map is accompanied by a description of the victim and suspect, their relationship to each other, the date and location of the attack, the motive behind the murder, and the method used to carry it out.

There are approximately 90,000 schools in our nation with a population of 46.5 million students on campus at any one time; this does not include the faculty, administrators, or support staff serving our student population. Geographic Information Systems (GIS) can be used as a technology to assist law enforcement and other public safety providers in the response to critical incidents at our schools. GIS can store vast amounts of spatial information such as the location of any building, office, or space on campus. Every piece of information that our schools store in their databases can be digitized and applied to a GIS system to provide public safety personnel with a visual depiction of what is facing them prior to their arrival at a critical incident.Law enforcement, fire personnel, school personnel,
and other public safety agencies can share this information.
GIS or “smart maps” provide a police department’s dispatchers with a spatial layout of a school, thereby allowing immediate retrieval of information about locations from their consoles. Dispatchers can display where a caller may be hiding from an active shooter on campus which would speed up the tactical response. Columbine is an example of having insufficient information to conduct a tactical response to an active shooter on campus. From the time the shootings began, it took 46 minutes before a tactical unit entered the school and once there, they had difficulty obtaining floor plans which hampered their life saving activities. Columbine has taught us that we must be prepared for the worst. We must train and plan for something that “could never happen in our community.” Using the powerful mapping capabilities of GIS, officials can better prepare for on campus crisis such as school shootings.

The University of Miami, like most universities, has a police department on campus. However, they take on a somewhat unusual approach to fighting crime at a college level by instituting a crime mapping and analysis program. The maps are used to proactively detect crime patterns, trends and series. Data developed through this program guides the uniform police patrol strategy, area checks, undercover and sting operations, covert initiatives and general resource deployment. By applying GIS, officers are seeing increasing criminal apprehensions and the clearances of cases.
The green dots represent burglaries at the University in 2007.
