Gap acceptance at stop-controlled T-intersections in a simulated rural environment

A high proportion of road crashes occur at intersections: in Victoria, Australia, 15% of fatal crashes and 25% of serious injury crashes occur at T-intersections, with similar proportions occurring at cross intersections. Many of these crashes can be attributed to drivers’ inappropriate gap selection. The current study used a driving simulator to examine the influence of both the driver’s intended manoeuvre and the gap duration on gap acceptance behaviour at stop-controlled T-intersections. Drivers completed 18 gap acceptance trials, with manoeuvre (turning across traffic, merging with traffic) and gap duration (3–11 s) manipulated within-subjects. There was a trend whereby drivers accepted shorter gaps when turning across traffic compared to merging with traffic, which was significant at longer gaps (⩾9 s) but not at shorter, safety–critical gaps (⩽8 s). In addition, accepted lag times varied with manoeuvre. When merging with traffic drivers demonstrated longer accepted lag times, suggesting that turn strategies differ depending on traffic direction and intended manoeuvre. Overall the results suggest that the drivers’ intended manoeuvre influences gap acceptance, although gap duration remains the most influential factor. Implications of these findings for the development and design of intersection decision support systems are discussed.     

Recognizing the Fundamental Right to be Fat: A Weight-Inclusive Approach to Size Acceptance and Healing From Sizeism

Abstract

Sizeism permeates and shapes how scientific and professional communities—including therapists—perceive, understand, and behave toward anyone considered fat. In this article, we use scientific evidence to argue for the recognition and establishment of fat acceptance to subvert sizeism. We first critically review the Weight Normative Approach, which dominates scientific discourse on weight, despite being based on sizeist assumptions that are discredited by data. We then articulate the tenets of the Weight Inclusive Approach, which honors size diversity and the promotion of wellness within a social justice framework. We end with strategies for therapists to align their practice with the Weight Inclusive Approach.
