Horse and Buggy Crash Study III: Low Illumination and the Sun’s Glare in Crashes between Motor Vehicles and Amish / Old Order Mennonite Horse and Buggies

Journal of Amish and Plain Anabaptist Studies

Anderson, Cory. 2014.


Research Points
  • Analyzes time-of-day risk patterns by comparing 733 Amish/Mennonite buggy crashes from 1998-2006 in Pennsylvania (denominator) to new buggy traffic count data (n=144) collected over two cross-seasonal 12-hour observation periods (numerator)

  •  Times of day with transitional illumination (dawn/dusk) pose the greatest crash risk for Amish horse-drawn buggies, likely due to glare and low visibility.

  • Low early evening dip in risk unexplained, though possibly due to low buggy traffic during traditional supper times

  • Informs potential interventions that accommodate mixed-speed traffic such as variable speed limits and wide road shoulders
