Driver behaviour and driver experience of partial and fully automated truck platooning: a...

This paper builds our knowledge of truck driver behaviour in and experience of automated truck platooning, focusing on the effect of partially and fully automated truck platoons on driver workload, trust, acceptance, performance, and...

Attitudes among older drivers towards medical assessment at renewal of driving license in...

Purpose: The aim was to examine attitudes among older adults in Sweden as regards a possible legislation for medical assessment at license renewal depending on their health status (vision and hearing) and gender.Methods: A questionnaire study...

Vision measurability and its impact on safe driving: a literature review

Knowledge of measurability of vision and its impact on safe driving have been proven to be important to secure a safe traffic system. Several different approaches to measuring visual function in order to improve road safety have been identified...

Vision measurability and its impact on safe driving: a literature review

Knowledge of measurability of vision and its impact on safe driving have proven to be important to secure a safe traffic system. Several different approaches to measure vision in order to improve road safety have been identified around the world. A...

Läsbarhet av vägskyltar i form av LED-skylt: färgkombination och fontstorlekens betydelse...

The readability of road signs was studied and in particular the LED format. The purpose of this study was to study the effect of color combination, font size and light conditions on readability. 101 students participated in the study, where 32 were...

Elvägar i körsimulator: design, test, utvärdering och demonstration av elvägstekniker och...

Electric road systems, ERS, where vehicles receive electricity continuously while driving, could be a way to reach the target of a fossil-free transport sector. A demonstration environment in a driving simulator was developed in order to test and...

Synförmågans mätbarhet och inverkan på säker bilkörning: en litteraturstudie

The purpose of this study was to provide an overview of vision abilities that are important for safe driving. Knowledge of measurability of vision and its impact on driving have proven to be important to secure a safe traffic system. Several...

Effect of hearing loss on traffic safety and mobility

Research into the effect of hearing loss (HL) on traffic safety and mobility is limited and the empirical findings are somewhat inconsistent. HL is one of the most frequent sensory deficits in humans, leading to loss of auditory information, which...

Bicyclists’ visual strategies when conducting self-paced vs. system-paced smartphone...

Visual distraction among cyclists interacting with their mobile phones is a growing concern. Yet, very little research has actually investigated how cyclists apply visual strategies and adapt task execution depending on the traffic situation. The...

Principle Other Vehicle Warning

The only possibility for a driver to avoid a collision may sometimes be to issue a warning to another driver. Connecting the horn and the headlight to an already existing sensor system could be a cost effective solution. This report covers the...

Cognitive workload and visual behavior in elderly drivers with hearing loss

The purpose was to examine eye tracking data and compare visual behavior in individuals with normal hearing (NH) and with moderate hearing loss (HL) during two types of driving conditions: normal driving and driving while performing a secondary...

Effects of hearing loss on traffic safety and mobility

The aim of this PhD thesis was to investigate traffic safety and mobility for individuals with hearing loss (HL). Three studies were conducted: 1. a questionnaire survey aimed to evaluate differences in choice of transportation that might be related...

The influence of hearing loss on transport safety and mobility

Purpose: To examine how road users with different degree of hearing loss experience safety and mobility in transport situations, compared to road users with normal hearing.Methods: A questionnaire study was conducted with participants recruited from...

Cognitive workload and driving behavior in persons with hearing loss

Purpose: To compare the effect of cognitive workload in individuals with and without hearing loss, respectively, in driving situations with varying degree of complexity.Methods: 24 participants with moderate hearing loss (HL) and 24 with normal...

Hearing loss and a supportive tactile signal in a navigation system: Effects on driving...

An on-road study was conducted to evaluate a complementary tactile navigation signal on driving behaviour and eye movements for drivers with hearing loss (HL) compared to drivers with normal hearing (NH). 32 participants (16 HL and 16 NH) performed...

The effect of hearing loss on eye movements when driving and an evaluation of tactile...

A field study was conducted to evaluate the use of an additional tactile signal in a navigation system and to examine the effect of hearing loss on eye movements. 32 participants took part in the study, whereof 16 with normal hearing and 16 with...

The effect of hearing loss on driving performance and experience of navigation system

A field study was conducted to evaluate the use of an additional tactile signal in a navigation system and to examine the effect of hearing loss on driving behavior. 32 participants took part in the study, whereof 16 with normal hearing and 16 with...

Driver reactions to horn and headlight warnings in critical situations: A simulator study

This paper presents a driving simulator study on driving behavior in a critical head-on collision scenario. The study aims at providing basic understanding of driver responses to headlight and horn warning coming from another vehicle a time critical...

Hearing loss and transport

The objective of this study was to examine through a questionnaire how road users with different degree of hearing loss experience safety and mobility in transport situations compared to road users without hearing loss.Participants were recruited...

Effects of road surface appearance and low friction warning systems on driver behaviour...

Warning systems for slippery road conditions are a potential newcomer among driver support systems. A total of 75 participants drove in a high-fidelity driving simulator on roads with both visible and invisible ice, to investigate to which extent...

Fatigue at sea: a field study in Swedish shipping

The purpose of this study was to collect data about the fatigue level of bridge watch keepers to use for revising earlier sleep models, and devise innovative solutions for the shipping industry. Data collection included interviews with shipping...
