Effect Of Short-Storage Hrgcs On Driver Decision Behavior And Safety Concerns: Real-World Analysis And Experimental Evidence, Anne Linja
Dissertations, Master's Theses and Master's Reports
Vehicle-train collisions at highway-rail grade crossings (HRGCs) continue to be a safety concern, and despite improvements in warnings, many of these incidents are attributed to human error. In some cases, distractions other than railroad traffic, such as HRGCs with limited space between the railroad tracks and the highway intersection, may create additional cognitive burdens for drivers. We investigated the effect of HRGC type (short-storage vs. non-short storage) on driver attention and decision-making in two studies. In Study 1, we systematically analyzed 996 incidents from 2017-2019 from the Federal Railroad Administration’s Safety database. Driver decision making and outcomes were different depending …
Getting Active With Passive Crossings: Investigating The Efficacy Of In-Vehicle Auditory Alerts For Rail Road Crossings, Steven Landry
Getting Active With Passive Crossings: Investigating The Efficacy Of In-Vehicle Auditory Alerts For Rail Road Crossings, Steven Landry
Dissertations, Master's Theses and Master's Reports
Train-vehicle collisions at highway-rail grade crossings continue to be a major issue in the US and across the world. Installing additional hardware at individual crossings is expensive, time consuming, and potentially ineffective. To prevent recent trends in safety improvement from plateauing, experts are turning towards novel warning devices that can be applied to all crossings with minimal cost. In-vehicle auditory alerts (IVAAs) could potentially remedy many of the human factor issues related to crossing safety in a cost effective manner.
This thesis presents a series of experiments designing and testing an IVAA system for grade level railroad (RR) crossings. Study …
