The use of partially-automated systems require drivers to supervise the system functioning and resume manual control whenever necessary. Yet literature on vehicle automation show that drivers may spend more time looking away from the road when the partially-automated system is operational. In this study we answer the question of whether this…

Partially autonomous vehicles can help minimize human errors. However, being free from some driving subtasks can result in a low vigilance state, which can affect the driver's attention towards the road. The present study first tested whether drivers of partially autonomous vehicles would benefit from the addition of auditory versions of the…

This study explores the important communicative roles carried out by road signs both directly and indirectly. The qualitative analysis is based on a corpus of 150 road signs collected from signage on state and local highways and roadways in seven U.S. states. Road signs were identified as either full, grammatical sentences or as block language.…

A group of adult individuals with dyslexia and a matched group of normally reading individuals participated in a driving simulation experiment. Participants were asked to read the word presented on every direction traffic sign encountered along a route, as far as possible from the sign, maintaining driving performance. Word frequency and word…

Connecting just four components that compose modern geographic information systems (GIS)--field surveys, dashboards, interactive maps, and story maps--can help foster spatial thinking, critical thinking, and rigorous use of GIS tools and data. The guidelines in this article walk an educator through the creation of a survey in Survey123, mapping…

The aim of this research was to test whether there is an inherent difficulty in understanding prohibition signs rather than obligation signs. In the experiment conducted, participants decided whether simple car movements presented on a computer screen were allowed or not according to either obligation or prohibition traffic signs. The information…

Designed to provide instructors with resource materials for driver education, this book contains mainly materials on established safe driving procedures. An introduction defines a procedure as describing ways in which a driver can comply with the law to do something extra that will increase his/her safety and prevent congestion and collision.…

The Florida Department of Transportation used a series of changeable-message signs that functioned as freeway guide signs to divert traffic to Universal Theme Park via one of two eastbound exits based on traffic congestion at the first of the two exits. An examination of crashes along the entire route indicated a statistically significant increase…

A study was conducted to investigate the traffic engineering factors that influence speed variance and to determine to what extent speed variance affects accident rates. Detailed analyses were carried out to relate speed variance with posted speed limit, design speeds, and other traffic variables. The major factor identified was the difference…

This guide for implementing performance-based curriculum is intended to teach students decision-making driving. Heavy emphasis is put on the tasks and concepts involving traffic flow tasks (interacting with other highway users) and the functions and factors that affect that interaction. It is a "90-hour" guide, that is, the average student needs…

This driver education curriculum for secondary students contains three learning activity packages (LAPs). The first LAP provides an overview and orientation to the course. The second LAP covers the basic control procedures for driving a car. The third LAP covers several tasks involved in normal driving, including observing, communicating,…

Specific information, identification, and direction to and within the campus as factors determining a campus sign system are discussed in terms of--(1) needs requiring an identification sign system, (2) recommendations for initiating a comprehensive sign system for the university, and (3) application procedures as they relate to streets, walkways,…
