GIS Informs Public of Neighborhood Speed Surveys

The speed at which vehicles travel can have a dramatic effect on a residential neighborhood. If there are particular streets or neighborhoods that vehicles have a tendency of driving too fast through, the public well-being is in jeopardy. The City of Park Ridge, IL Police department conducts a number of speed surveys throughout the year to measure the average speed on a given block over a period of time, generally in the week to ten day range. Using data from these surveys, decisions can be made to add additional signs, barriers, or traffic devices to decrease speeding if the statistics warrants it. However, the Police department wanted a method of having all of this speed survey information available to the public, without having the resident have to sift through a lengthy list to find information on their street. To accomplish this, Geographic Information Systems (GIS) was chosen as the optimal way to display this information to the public.

A custom layer was created for the village’s browser-based mapping application, MapOffice™, a property information search program, showing all the speed survey locations completed in the city dating back to 2008. A direct link to this layer was posted on the Park Ridge Police website where a resident could search for a speed survey location by just typing in an address along the survey route. All relevant speed survey statistics could then be accessed by clicking on the survey line along the particular street. By having this information available to the public, residents can now be more aware of the speed survey program as a whole, along with seeing survey statistics for areas that they may have originally been inquiring about.
