Although many have an idea of what the term “driver distraction” means, there is no common definition within the research community. Additionally, there are many studies that have investigated the topic, but with varying and sometimes conflicting results. What should be made of these discrepancies? This four-hour web seminar will provide an overview of driver distraction (predominantly electronic devices): the problem; how to define it; the current state of research and how to critically evaluate that research to make informed decisions; and the effectiveness of state laws and fleet policies to reduce it.

Designing vehicles with good ergonomics is one of the many factors needed to achieve high customer satisfaction. A basic source for comfort (or discomfort) lies in the vehicle’s seats. To design for seat comfort requires knowledge of the size of the driver, the structure of the seat, the position of the seat in the vehicle and the trip duration. Papers offers in this session could include topics such as seat back angle, vehicle packaging and trip duration.

Abstract Many of the information systems in cars require visual attention, and a way to reduce both visual and cognitive workload could be to use sound. An experiment was designed in order to determine how driving and secondary task performance is affected by the use of information sound signals and their spatial positions. The experiment was performed in a driving simulator utilizing Lane Change Task as a driving scenario in combination with the Surrogate Reference Task as a secondary task. Two different signal sounds with different spatial positions informed the driver when a lane change should be made and when a new secondary task was presented. Driving performance was significantly improved when both signal sounds were presented in front of the driver. No significant effects on secondary task performance were found. It is recommended that signal sounds are placed in front of the driver, when possible, if the goal is to draw attention forward.

Abstract The number of advanced driver assistance systems is constantly increasing. Many of the systems require visual attention, and a way to reduce risks associated with inattention could be to use multisensory signals. A driver's main attention is in front of the car, but inattention to surrounding areas beside and behind the car can be a risk. Therefore, there is a need for driver assistance systems capable of directing attention to the sides. In a simulator study, combined visual, auditory and vibrotactile signals for directional attention capture were designed for use in driver assistance systems, such as blind spot information, parking assistance, collision warnings, navigation, lane departure warning etc. An experiment was conducted in order to measure the effects of the use of different sensory modalities on directional attention (left/right) in driver assistance systems.

This paper reports on the development and validation of an automated seat-dimension extraction system that can efficiently and reliably measure the SAE J2732 (2008) seat-dimensions from 3D seat scan data. The automated seat-dimension extraction process in the system consists of four phases: (1) import 3D seat scan data along with seat reference information such as H-point location, seatback and cushion angles, (2) identify centerline and lateral cross-section lines on the imported 3D seat scan data, (3) identify landmarks on the centerline and cross-section lines based on the SAE J2732 definitions, and (4) measure seat-dimensions using the identified landmarks. To validate the automated seat measurements, manually measured dimensions in a computer-aided-design (CAD) environment and automatically extracted ones in the current system were compared in terms of mean discrepancy and intra- and inter-observer standard deviations (SD).

The evaluation of perceived comfort inside a car, in the early stages of design process, is still an open issue. Modern instruments like CAE (Computer Aided Engineering) and DHM (Digital Human Modeling) already offer several tools for a preventive evaluation of ergonomics parameters for car drivers through the use of detailed CAD (Computer Aided Design) models of car-interiors and by the multi-body approach for evaluating movements and interactions. Nevertheless, it is not enough because the subjectivity of comfort perception is due to parameters that are very difficult to be evaluated in the early stage of design and need “hard-prototypes” that, often, are too expensive to be realized. In the latest 30 years, several researchers tried to develop methods to objectivize the comfort performance but most of them are based on questionnaires, marketing researches, physiological and biomechanical analyses, and need devices or interactions that modify the perceived comfort.

Automation of automobile can be expected to improve safety, comfort and efficiency, and developed in every countries. Automated driving is introducing according to automated levels from 0 to 5 (0:no automation, 1:driver assistance, 2:partial automation, 3:conditional automation, 4:high automation, 5:full automation). Currently, feasible automation level is considered to be Level 2 or 3, and take-over from automated system to human manual driving is needed when the automated system overs at these levels. In this situation, required time for take-over is an important issue. This study focus on describing driving simulator experimental results of required time for take-over. The experimental scenario is that the automated system finds an object ahead when automated driving on the high way and issues take-over request to the driver. The subject driver is under the following driver situations : hands-on or hands-off to the steering, and strong or weak distractions.

The theory of neuroplasticity posits that the brain continues to change as we age. Thus, cognitive or brain training has been offered as a way for seniors to remain cognitively engaged. Recent research has found substantial reductions in crash rates for seniors who underwent particular brain training protocols; however, specific behaviors or performance metrics which may have contributed to these findings were not examined. The current study is the first to document detailed measures of driver behavior that could support an improvement in driving safety following cognitive training. Fifty-five volunteers participated in one of two cognitive training programs (or were part of a control group). One training program was a commercially available computer-based approach. The other was a novel in-vehicle approach developed by Toyota engineers which employed an implicit learning paradigm.

The objective of this research was to measure and understand the preferred seat position of older drivers and younger drivers within their personal vehicles to influence recommended practices and meet the increased safety needs of all drivers. Drivers with improper seat position selection may affect their capacity to see the roadway and reach the vehicle’s controls, such as the steering wheel, accelerator pedal, brake pedal, clutch pedal, and gear selector lever as well as impact one’s safety during a crash event. Because of the stature changes that are associated with ageing and the fact that stature is normally distributed for both males and females, it was hypothesized that the SAE J4004 linear regression would be improved with the inclusion of a gender and age terms. The hypothesized terms would provide a more accurate model to predict the seat track position of older drivers.

The ability to independently transfer into and out of a vehicle is essential for many wheelchair users to achieve driving independence. This paper presents the results of an exploratory study that investigated the transfer strategies of wheelchair users who drive from their driver’s seat and not from their wheelchair. The goal of this study was to identify typical ingress and egress motions as well as “touch points” of wheelchair users transferring into and out of the driver’s seat. While motion databases exist for the ingress and egress of able-bodied drivers, this study provides insight on drivers with physical disabilities. Twenty-five YouTube videos of wheelchair users who transferred into and out of their own sedans were analyzed.

While motorcycle safety frequently focuses on topics like helmet use and engineering aspects such as anti-lock braking systems, little research has investigated aging motorcyclists’ use of technologies (i.e., texting, navigation systems, etc.) or the characteristics of older motorcyclists (defined as above the age of 40) who use them. This study sought to provide an overview of the types of technologies that motorcyclists use while riding, problems or concerns about those technologies, and motorcyclist demographics by surveying a convenience sample of typical motorcyclists in the United States. The sample included 91 riders (78 males and 13 females) between the ages of 20 and 71 years (mean= 50.5, SD= 10.8). Surveyed motorcyclists answered questions about riding experience and training, technologies they use while riding, ease and frequency of use of those technologies, issues with the technologies, as well as riding behaviors and habits.

The paper is focused on both the the subjective and the objective ride comfort of farm tractors. The experimental measurement of the relevant accelerations occurring at the tractor body, at the cabin and at the seat was performed on a number of different farm tractors. A subjective rating of the ride confort was performed. The comfort index was computed according with ISO 2631 and other standards. The acceleration of the seated subject was computed by means of a proper mechanical model of farm tractor and derived at different positions on the subject body. It turned out that the acceleration of the lower torso was particularly relevant for establishing a matching between the subjective perception and the objective measurement and computation. A number of indices have been derived from the measured data which are able to correlate the subjective drivers' feeling with the measured accelerations.

This paper introduces a new method for driving style identification based on vehicle communication signals. The purpose of this method is to classify a trip, driven in a vehicle, into three driving style categories: calm, normal or aggressive. The trip is classified based on the vehicle class, the type of road it was driven on (urban, rural or motorway) and different types of driving events (launch, accelerating and braking). A representative set of parameters, selected to take into consideration every part of the driver-vehicle interaction, is associated to each of these events. Due to the usage of communication signals, influence factors, other than vehicle speed and acceleration (e.g. steering angle or pedals position), can be considered to determine the level of aggressiveness on the trip. The conversion of the parameters from physical values to dimensionless score is based on conversion maps that consider the road and vehicle types.

In china there are many mixed driving roads which cause a lot of safety problems between vehicles and pedalcyclists. Research on driver behavior under risk scenarios with pedalcyclist is relatively few. Driver brake parameters under naturalistic driving are studied in this paper. Brake reaction time and maximum brake jerk are used to evaluate driver brake reaction speed. Average deceleration is used to evaluate the effect of driver brake operation. Maximum deceleration is used to evaluate driver braking ability. Driver behaviors collected in China are classified and risk scenarios with pedalcyclist are obtained. Driver brake parameters are extracted and statistical characteristics of driver brake parameters are obtained. Influence factors are analyzed with univariate ANOVA and regression analysis. The results show that driver brake parameters under risk scenarios with pedalcyclist obey log-normal distribution.

A particular challenge in the development of passenger cars is within prognosis of the vibration comfort. The range of requirements is broad as the excitation varies between cobblestones up to California roads. A further demand is the driver expectation which is different for a pickup or for a sports car. There exist several approaches for assessing the vibrations of occupants while driving. On the one side the comfort is evaluated by integral quantities as the SEAT value taking into account a weighting based on the human body sensitivity. Another approach is the dimension of perception, developed by BMW, which is similar to psychoacoustics as the frequency range is separated with respect to appearing vibration phenomena. In the centre of all activities is the seat transmissibility in the frequency range, describing the relation between the input at the seat slides and the output at the interface of human body and trim.

You plan on buying a new car? You have searched the internet, set a financial limit and are now heading towards your preferred dealer - and take a seat in the car of your choice! This first impression of seating comfort and package design is a decision making criteria when selecting a new car. All OEMs are aware of this and quite a lot of companies use the „passenger comfort“ issue to stand out from their competitors. But how can we objectively evaluate passenger comfort? This complex criterion is dominated by a mixture of several aspects as posture, pressure distribution, internal tissue loads or handling of steering wheel or gear shift. A method to evaluate are hardware tests with human subjects, who are sensitive to all of these aspects. But the reproducibility of subjective tests for comparing design variants is a questionable issue and the costs for each test cycle using new prototypes are very high.

The vehicle crash pulse severity is a measure of how severely the vehicle crash pulse has an effect on the occupant injury. The objective of this research is to evaluate the assessability of vehicle crash pulse severity in frontal New Car Assessment Program (NCAP) tests. In this study, the existing metrics derived from vehicle crash pulse in the frontal impact are reviewed and categorized into 4 groups in the way of how occupant responses are considered. Then the severity of vehicle crash pulses of the frontal NCAP tests was evaluated by existing metrics. A total of 60 frontal NCAP test data collected from the MY 2012 vehicle test program are analyzed. The linear regression analyses and sled test simulations are conducted to identify their correlation to other metrics and dummy injuries. The results show that some of existing metrics are able to assess crash pulse severity in frontal NCAP tests.
