This paper presents an analysis of rearward gap acceptance characteristics of drivers of large trucks in highway lane change scenarios. The range between the vehicles was inferred from camera images using the estimated lane width obtained from the lane tracking camera as the reference. Six-hundred lane change events were acquired from a large-scale naturalistic driving data set. The kinematic v...

This study is to fill up a research gap on examining the differences in normative beliefs (namely acceptance of weaknesses, acceptance of provoked aggression, and acceptance of unprovoked aggression) among different subtypes of aggressors and non-aggressors (reactive aggressors, proactive aggressors, reactive-proactive aggressors, and non-aggressors). 2,236 students (1,372 males and 864 females...

Far too often, there is a gap between research and policy and practice. Too much research is undertaken with little relevance to real life problems or its reported in ways that are obscure and impenetrable. At the same time, many policies are developed and implemented but are untouched by, or even contrary to evidence. An accompanying paper describes an innovative progr...

Methodologies for modeling ramp driver acceleration-deceleration and gap acceptance behavior during freeway merge maneuvers are presented. This study serves an important purpose by pointing to the limitations of current freeway merge models which treat the ramp driver acceleration-deceleration and gap acceptance behavior as deterministic phenomena. In addition, the interdependence of freeway me...

The driver gap acceptance and rejection behavior during mandatory lane changes on a multilane freeway are analyzed in this paper. Gaps are accepted or rejected based on comparison with a minimum value generally defined as the critical gaps. Critical gaps are estimated based on the accepted and rejected gaps observed in the field. Driver behavior can be classified as consistent or inconsistent o...
