Summary
This study investigates the impact of smartphone usage, specifically Global Positioning System (GPS) navigation applications, on driver performance and safety within highway work zones. Motivated by rising smartphone ownership and the high risk of distracted driving in temporary traffic control (TTC) settings, the research addresses the gap in understanding how GPS distractions affect driver behavior when workers are present. The authors hypothesize that drivers subjected to GPS navigation tasks will exhibit worse performance and more unsafe behaviors than those driving without such distractions. The methodology employed a two-phase approach: an online survey and a driving simulator experiment. The survey, distributed to 216 licensed drivers in Puerto Rico, assessed perceptions of distraction levels and knowledge of TTC components. The experimental phase utilized a driving simulator at the University of Puerto Rico at Mayagüez with 24 subjects. Twelve scenarios were designed based on a four-lane rural freeway, varying by workspace location (right lane, left lane, or right shoulder), presence of traffic, and GPS distraction status. In GPS scenarios, drivers received visual and auditory instructions to take an exit ramp that was closed due to construction. Key performance metrics included the standard deviation of lateral position (SDLP), mean speed, speed variability, and acceleration noise. A Latin square design was used to randomize scenario order, mitigating fatigue and learning effects. The results revealed significant safety risks associated with GPS usage. At least 16.7% of subjects encroached into the workspace while using an active GPS when the work zone occupied the right lane and the exit ramp was closed. Furthermore, 67% of subjects performed evasive maneuvers to avoid impacting an inattentive worker who invaded the traffic space. Statistical analysis indicated that GPS distraction influenced lateral positioning and speed variability, particularly in complex scenarios involving lane closures and conflicting navigation instructions. The survey data complemented these findings by highlighting drivers’ self-reported engagement in distracting activities despite awareness of the risks. The study concludes that active GPS navigation significantly impairs driver performance in work zones, leading to lane encroachments and erratic maneuvers. These findings underscore the heightened vulnerability of road workers when drivers are distracted by smartphone applications. The authors recommend further research to refine TTC plans and driver education strategies to mitigate these risks. The study contributes to the field of transportation safety by providing empirical evidence on the specific dangers of GPS distractions in construction zones, supporting the need for stricter regulations or technological interventions to enhance worker and road user safety.
