Bicycle vs. Car Crash Analysis

Lexington, Kentucky. October 15, 2008 – October 14, 2013.

Lab_3_previewAn analysis of bicycle accidents reported by Kentucky law enforcement agencies over 5 years in Fayette County.

Within Fayette County, 396 bicycle and motor vehicle collisions were reported with 293 injuries and 3 fatalities. The average age of the cyclist was 29 years, 76% were male, and only 25% were wearing a helmet. 21% of the collisions were hit-and-run. The greatest rate, or density, of crashes centers on UK’s campus. The next highest density was downtown, followed by small increases in crashes near Harrodsburg and Waller Ave, Winchester Rd, and on Loudon Ave. Critical street segments in order of greatest number of crashes are: Limestone north of Virginia Ave, Euclid Ave east of Woodland Ave, Rose St between Euclid and Huguelet Dr, and Winchester Road near intersection with East Third St.


Of all workers (16 years and older) living in the Urban Service Area, only 0.94% say the actively bike commute to work. Within 0.5 miles of a bike lane or sharrow, the share of workers saying they bike commute rises to 1.7%. Also, 89% of bike commuters live within a half mile of a bike lane or sharrow. It is estimated that 25% of all reported accidents have happened on streets with a sharrow or bike lane.

Distressed Kentucky Areas

Ky Distressed Areas

A GIS analysis

Socioeconomic and Environmental Distress by Block Group in Kentucky

A preliminary fact: Landsat Annual Timelapse 1984-2012 (from Google’s Earth Engine project) shows a glimpse of the vast impact of surface mining in the eastern Kentucky coal fields.

Kentucky’s population is nearly balanced between urban and rural. 52% of Kentucky’s population lives in rural census block groups¹. Economic and social distress² is more likely to occur in rural areas. 61% of Kentucky’s distressed population lives in rural areas.

Surface coal mining³ mostly occurs in rural areas and the highest rate of mine permits to population occurs in distressed rural areas. 99.3% of mine permits exist in rural areas.

The rate of mine permits to persons is 12.8 permits per thousand residents in all distressed areas, 4.24 permits per thousand residents in transitional areas, and .221 permits per thousand residents in non-distressed areas. In the most severely distressed rural areas, the rate is the highest at 32.0 permits per thousand residents.

61.2% of all distressed rural areas have mine permits.

2013 Veterans Park Mountain Biking Trail Map

4.8-mile loop trail & out and back all on singletrack.

In tribute to Bike Lexington month, we’ve made a new map for beginning mountain bikers. If you’re new to trail riding and want tight, banking turns on fast, easy trail, then visit’s Lexington’s Veteran’s Park.

We created this map as a demonstration of small-area map making. We first walked the trail with a Trimble GPS unit this past winter to accurately locate the trail. We then used Kentucky’s new aerial photography and LiDAR elevation data to make 5-foot contours and heads-up digitized canopy coverage. We also pulled in the impervious and waterbody layers from the new Open Data Portal from LFUCG. This is all GIS data that has been created and/or made available in the past six months.

More nerd alert. The recent availability of small-scale mapping data is awesome. We thought we’d try to see how good this data is and make trail elevation profiles, which is included with this map. While the elevation profile is not perfect at this scale (with perhaps a +/- 8 ft height error for any given point on the profile), it gives a good distance measurement and represents well the relative slope of the trail. Since the vertical scale is not the same as the horizontal scale, the profile exaggerates the pumps & humps a rider faces…which means, the slopes are exaggerated.

Enjoy and tell us what you think.

Rephotographing Lexington’s Streetscapes

Rephotographing Lexington’s Streetscapes. Click to view Google Map.

A collaborative final project for GEO 172, Introduction to Human Geography, Fall 2012, BCTCS

The class was tasked with rephotographing the streetscapes of downtown Lexington captured by Asa Coleman Chin in 1920-1921. Sanborn maps of the areas Chin photographed are provided as a reference.

Students then researched Lexington newspapers for information about city life during the period 1907-1921. Historic themes of urban improvement, segregation, and riots emerge. Students’ photographs & research show monumental change in areas of civic life, but often little change in many areas of the city’s built environment.
