Pattern Analysis of Driver’s “Pressure-State-Response” in Traffic Congestion

Abstract

Traffic congestion, which has a direct impact on the driver’s mood and action, has become a serious problem in rush hours in most cities of China. Currently, the study about driver’s mood and action in traffic congestion is scarce, so it is necessary to work on the relationship among driver’s mood and action and traffic congestion. And the PSR (pressure-state-response) framework is established to describe that relationship. Here, PSR framework is composed of a three-level logical structure, which is composed of traffic congestion environment, drivers’ physiology change, and drivers’ behavior change. Based on the PSR framework, various styles of drivers have been chosen to drive on the congested roads, and then traffic stream state, drivers’ physiology, and behavior characters have been measured via the appropriative equipment. Further, driver’s visual characteristics and lane changing characteristics are analyzed to determine the parameters of PSR framework. According to the PSR framework, the changing law of drivers’ characteristics in traffic congestion has been obtained to offer necessary logical space and systematic framework for traffic congestion management.

Dimensions of driving anger and their relationships with aberrant driving

“…The mean score of 2.04 (on a 5-point scale) of the DBQ in this study was higher than that reported by Shi et al (2010) (mean = 1.26) and Xie and Parker (2002) (mean = 1.07). An item-by-item comparison showed that the scores of items from "emotional violation" and "maintaining progress violation" factors were higher in this study than the corresponding values in the previous two studies, which was probably due to the serious traffic congestion problem and the increasing driver conflicts on roads in China in recent years (Qi et al, 2013).…”

Development of models for assessing a driver's failure­free operation in a transportation system under conditions of traffic congestion

“…We should note that, in contrast to existing approaches, the probability of an accident for a particular vehicle on a section of a transport network depends not only on parameters of a network and traffic flows as in models (3) and (4). The probability also depends on the variable driver's response time, which increases, in turn, with the level of his fatiguemodels (5) to (7).…”

“…Traffic jams restrict driver's freedom of action significantly and lead to an increase in his emotional state and an increase in fatigue. Authors of paper [4] showed that traffic jams, which affect the mood and actions of a driver directly, became a serious problem at peak hours in most cities in China. The study of a mood and actions of a driver in traffic jams is insufficient currently, so it is necessary to study the relationship between the mood and actions of a driver and traffic jams.…”

Effect model of urban traffic congestion on driver’s lane-changing behavior

“…17 As a basis, pattern of driver's ''pressure-stateresponse'' (PSR) in traffic congestion has been established to reveal the characteristics of driver's eye movement in the congested condition, and PSR model is the theoretical foundation to study the effect of traffic congestion on driver's characteristics. 18 So, PSR model will extend to the aspect about driver's mental workload and behavior, then the accuracy and practicability of the PSR model is also proved. Testing design and implementation scheme are the key parts to establish the effect model of urban traffic congestion.…”
