PREFACE: This map represents a compilation of work and analysis from a multi-map format called “Story Map”. Story Maps guide viewers through an organized sequence of interactive maps, facts, statistics, and analyses about a single subject, the intent being a better understanding of a subject and its many facets. This is NKYmapLAB’s second use of the Story Map format to provide viewers with more information than can be provided in a single map product.
This map shows an analysis of walk-time and drive-time distances to parks throughout Kenton County. For the purposes of this study, a park was included in the analysis only if it is a publicly-accessible location with active recreation opportunities. Athletic facilities at schools, privately-owned recreation facilities, and ‘greenspace parks’ without active recreation facilities were not considered for this analysis.
The walk- time analysis assumed an average walking speed of 3.1 miles per hour, a commonly-accepted preferred walking speed. More information on that value can be found here at Wikipedia. The analysis looked at walk times of five, ten, 15, and 20 minutes, where a 5-minute walk covers about ¼ mile, and a 20-minute walk would cover about 1 mile (at 3.1 mph).
The drive-time analysis map uses posted speed limit values to determine how much distance could be covered in a set amount of time. Using speed limits, the drive time (in seconds) of each street was calculated. The analysis then looked at drive times of one, two, three, four, and five minutes to see how far a driver could get within each of those time limits.
Both analyses then calculated the number of households that were located inside each walk-time and drive-time interval and presented that as a percent of the total households in Kenton County.
All walk-time and drive-time analyses were conducted using a specialized GIS tool called Network Analyst—a detailed analytic tool that allows users to study service areas, drive times, routing, and barriers in a designated area using their own local data.
