A decade of car-cyclist collisions in Louisville: a spatio-temporal analysis.

by Elizabeth Ferguson Greenwell

This thesis has considered factors of the built environment to discover if cay-cyclist collisions display any patterns that could be used to improve cycling safety. This thesis contains an introduction, a literature review, an overview of the study area and data, a description of the methods, results, and discussion and conclusion section. This thesis is significant because it has been the first study to consider cyclist volume as an explanatory variable of the spatiality of car-cyclist dependence for Louisville, Kentucky. Through descriptive and spatial statistics, trends in car-cyclists were identified. Collisions occur more frequently in the summer, during commute hours, at signalized intersections, and near bus stops. It also evaluated the use of third-party sources as exposure measure and explanatory variables. This thesis also put forward recommendations to better the information available to study cyclist collisions, and ways to improve the safety of cyclists in Louisville.
