Bike/Pedestrian v. Car Collision AnalysisJanuary 2004 to April 2016 in Fayette County, Kentucky
During the 2016 spring semester, GEO 409 undergraduate GIS class analyzed and mapped collisions of cars with pedestrians and bicyclists. We focused on 12 years of data (1/2/2004 - 4/8/2016) for Fayette County, Kentucky, which contains the city of Lexington and a population of over 300,000. The county is home to Kentucky's largest university (us!) and offers a walkable and bikeable campus with connections to a vibrant downtown. Explore these maps to find demographic information of cyclists involved in collisions with automobiles.
3D mapping and scripting in ArcPyAutomating the processing of spatial data
In Geo 409, we developed tools to process spatial data for any area of interest and feed other visualization platforms, like QGIS 3d mapping and CartoDB. This lab had an utility outside of class. A guidebook publishing company, Wolverine Publishing, needed maps for a popular climbing area in Idaho, City of Rocks. Find the Github repo and sample maps here.
Lexington's Urban Tree Canopy Cover
An exploration of measuring canopy cover in Lexington's urban service area
Inspired by the Davey Resource Group's October 2013 study of canopy cover using 2012 NAIP imagery within Lexington's Urban Service Area, a GIS class at the University of Kentucky created a similar, though limited, evaluation. We used 2014 NAIP imagery to create an NDVI image and field tested our canopy threshold at a NDVI value of 0.23. Our measurement was generally higher by 1%, since we did not remove areas with a high vegetative index, such as baseball fields, as was done by the Davey Resource Group. Using zonal statistics on both canopy cover datasets, we counted the number of pixels classified as canopy cover by polygon features in parcels, landuse, and US Census blocks and block groups. We also looked at canopy rates per person via the 2010 census blocks and 2013 median home value.
Student Observations and Analysis of UK Campus Celebrations
During (and after) the 2015 UK men’s NCAA basketball tournament games
Their topics include: locations of campus rental properties, noise pollution from major party locations, population density, and changes in social media engagement during and after games.
A selection of student map projects, Fall semester, 2014
15 student teams from two GIS courses mapped, measured, and photographed 603 trees in the Arboretum Woods. Each team was given (approximately) an acre zone and they used common mobile devices and low-cost apps to GPS and photograph the most significant trees. Each team made a poster and presented them during a 2014 International GIS Day event. Since students photographed each tree, we made an interactive map that shows these photos and can be used for geolocation while in the woods. Look at trees now!
Hiking publication for the north half of the Daniel Boone National Forest
Four 19" x 27" maps show all official hiking trails in the north half of Kentucky's Daniel Boone NF. While focusing on the Sheltowee Trace, the publication shows popular destinations like the Red River Gorge and Cave Run Lake. The map includes 50-foot elevation contours, canopy cover, and GPS mapped trails at a scale of 1" to 1/2 mile. An exciting project has been launched to geocode and present a photograph for each mile of the Sheltowee Trace: http://www.SheltoweeTrace.com/hike

Lexington Walkability Analysis
How close do you live to a pedestrian path?
A Pedshed is used to show how many people are connected by pedestrian paths and sidewalks with either a five-minute or fifteen-minute walk. Only roads with sidewalks are included in the analysis. It is assumed that people can walk faster on pedestrian paths (3.4 mph) than roads with sidewalks (2.8 mph). That's fast! For more casual walking, speeds are about half as fast.
Paved paths and sidewalks were attributed and digitized from 2010 aerial photography by students in University of Kentucky Department of Geography's GEO 409 course, Spring 2014. This analysis has a focus on existing access and potential future access (of various completed designs) of Lexington's two longest shared-use trails, the Legacy and Town Branch Trails.
How more connected would Lexington be if the Legacy Trail and Town Branch Trail were completed?
Five-Minute Walk From All Existing Pedestrian Paths
Approximately 149,000 Fayette County residents (50%) live within a five-minute walk (on a sidewalk) of an existing paved pedestrian path, such as shared-use trail, park walking trail, and school walking path.
Fifteen-Minute Walk From Existing Town Branch & Legacy Trails
Approximately 11,500 Fayette County residents (approximately 3.8%) live within a fifteen-minute walk (on a sidewalk) of existing Town Branch Trail and Legacy Trail facilities. View a dynamic map of this scenario here.
Fifteen-Minute Walk From Completed Town Branch Trail Phase III Without Bridge Across Town Branch
Approximately 12,800 Fayette County residents (4.3%) would live within a fifteen-minute walk (on a sidewalk) of Phase III of Town Branch Trail and Legacy Trail facilities. This option does not include a bridge across Town Branch.
Fifteen-Minute Walk From Potential Future Town Branch & Legacy Trails (with bridge across Town Branch)
Approximately 38,900 Fayette County residents (12.5%) would live within a fifteen-minute walk (on a sidewalk) of finished Town Branch Trail and Legacy Trail facilities. View a dynamic map of this scenario here.
Pedestrian V Car Collision Analysis
Fayette & Jefferson Counties, February, 2014.
Point locations for collisions were downloaded from the Kentucky Collision Analysis for the Public (http://crashinformationky.org/) hosted by the Kentucky State Police. Analysis was performed for Kentucky's Fayette and Jefferson Counties for data period January 5, 2003 - February 23, 2014 as part of GEO 409, Spring 2014. An ArcGIS ModelBuilder and Python script was created to automate geoprocessing of data and map generation.
- AMONG ALL COLLISIONS 4,592 pedestrians v. car collisions occurred with 173 pedestrian fatalities (3.8% of total) and 4223 pedestrian injuries (92% of total).
- AMONG ALL COLLISIONS WITH PEDESTRIANS USING ALCOHOL OR DRUGS 257 pedestrians v. car collisions occurred with 26 pedestrian fatalities (10%) and 227 pedestrian injuries (88% of total).

Bicycle vs. Car Crash Analysis
Kentucky's Distressed Areas
Kentucky’s population is nearly balanced between urban and rural with 52% living in rural census block groups. Economic and social distress is more likely to occur in rural areas. 61% of Kentucky’s distressed population lives in rural areas and the majority of those areas have surface coal mining permits.
