The use of mobile phones while driving is increasing at an alarming rate despite the associated crash risks. A significant safety concern is that driving while distracted by a mobile phone is more prevalent among young drivers, a less experienced driving cohort with elevated crash risk. The objective of this study was to examine the gap acceptance behavior of distracted young drivers at roundabouts. The Center for Accident Research and Road Safety-Queensland Advanced Driving Simulator was used to test participants on a simulated gap acceptance scenario at roundabouts. Conflicting traffic approaching from the right of a four-legged roundabout was programmed to show a series of vehicles with the gaps between them proportionately increased from 2 s to 6 s. Thirty-Two licensed young drivers drove the simulator under three phone conditions: baseline (no phone conversation), a hands-free phone conversation, and a handheld phone conversation. Results show that distracted drivers started responding to the gap acceptance scenario when they were closer to the roundabout and they approached the roundabout at slower speeds. These drivers also decelerated at faster rates to reduce their speeds before gap acceptance compared with nondistracted drivers. Although accepted gap sizes were not significantly different across phone conditions, differences in the safety margin at various gap sizes-measured by postencroachment time (PET) between the driven vehicle and the conflicting vehicle-were statistically significant across phone conditions. PETs for distracted drivers were smaller across different gap sizes and suggest that a smaller safety margin was accepted by distracted drivers compared with nondistracted drivers.

In the Canadian context, stunt driving refers to street racing and associated risky driving activities. Although no national official statistics are available, other data have found that stunt driving is a common activity among young males. Research from Australia, New Zealand and other jurisdictions has shown that those engaged in stunt driving are at higher crash and violation risk. The purpose of this study was to examine the correlates of self-reported stunt driving and the effects of thrill seeking, competitive driving and attitudes towards risky driving on self-reported stunt driving among a sample of car and racing enthusiasts through a web-based survey of car and racing clubs. The Internet questionnaire included: (1) personality variables (Driver Thrilling Seeking Scale, Competitive Attitude Toward Driving Scale); (2) beliefs about seriousness and perceived crash likelihood of various drivers and driving behaviours; (3) attitudes regarding Ontario, Canada's new stunt driving legislation and street racing/stunt driving; (4) risky driving behaviours, as measured by the Manchester Driver Behaviour Questionnaire subscale, Self-Report Driver Aggression Questionnaire, Risk-Taking Driving Scale, collisions in past five years, traffic offences in last year and stunt driving, as defined by Ontario's Street Racers, Stunt and Aggressive Drivers Legislation. A minority of car and racing enthusiasts reported stunt driving. Clear differences emerged between the self-reported stunt drivers and non-stunt drivers. Stunt drivers were more likely to be young, less concerned about excessive speeding and street racing, to hold more negative attitudes towards Ontario's stunt driving legislation and more positive attitudes towards street racing and stunt driving, to score higher on the driver thrill seeking, competitive attitude toward driving and risky driving scales and more likely to report traffic offences in the past year. The sequential logistic regression showed that personality characteristics and attitudes provided unique contributions to the model in predicting stunt driving. Thus, although a minority of the sampled car and racing enthusiasts engage in stunt driving, further interventions need to be considered to reduce their risky driving beliefs, attitudes and behaviours. © 2013 Elsevier Ltd.

Improving safety at railway level crossings is an important issue for the Australian transport system. Governments, the rail industry and road organisations have tried a variety of countermeasures for many years to improve railway level crossing safety. New types of intelligent transport system (ITS) interventions are now emerging due to the availability and the affordability of technology. These interventions target both actively and passively protected railway level crossings and attempt to address drivers' errors at railway crossings, which are mainly a failure to detect the crossing or the train and misjudgement of the train approach speed and distance. This study aims to assess the effectiveness of three emerging ITS that the rail industry considers implementing in Australia: a visual in-vehicle ITS, an audio in-vehicle ITS, as well as an on-road flashing beacons intervention. The evaluation was conducted on an advanced driving simulator with 20 participants per trialled technology, each participant driving once without any technology and once with one of the ITS interventions. Every participant drove through a range of active and passive crossings with and without trains approaching. Their speed approach of the crossing, head movements and stopping compliance were measured. Results showed that driver behaviour was changed with the three ITS interventions at passive crossings, while limited effects were found at active crossings, even with reduced visibility. The on-road intervention trialled was unsuccessful in improving driver behaviour; the audio and visual ITS improved driver behaviour when a train was approaching. A trend toward worsening driver behaviour with the visual ITS was observed when no trains were approaching. This trend was not observed for the audio ITS intervention, which appears to be the ITS intervention with the highest potential for improving safety at passive crossings. © 2015 Elsevier Ltd.

The experiences of immediate-uptake driver's license holders (intermediate licensure at age 17 or 18 years; n = 928) and delayed-uptake driver's license holders (intermediate licensure at age 19 to 20 years, n = 158) were explored in the Australian state of Queensland, where the graduated driver licensing (GDL) program applies to all novice drivers regardless of age. Drivers who obtained a Provisional 1 (P1; intermediate) license completed surveys exploring their experiences prelicensing and as learners, including the Behavior of Young Novice Drivers Scale (BYNDS) evaluation. Six months later, 351 drivers from this sample (n = 300 immediate-uptake driver's license holders) completed a survey exploring their experiences while driving with a P1 license. Delayed-uptake learners reported significantly more difficulty gaining driving practice, which appeared to be associated with significantly greater engagement in unsupervised driving during the learner period. Although a larger proportion of delayed-uptake novices, particularly males, reported the use of more active punishment avoidance strategies (avoiding police, talking themselves out of a ticket) during the P1 license phase, no significant differences in the BYNDS scores during the learner and P1 license phases were found by license uptake category. Delayed-uptake novices reported more difficulty in meeting GDL requirements and placed themselves at increased risk by driving unsupervised during the learner license phase. Additional efforts, such as mentoring programs, that can support delayed-uptake learners in meeting their GDL obligations merit further consideration to allow this group of novice drivers to gain the full benefits of the GDL program and to reduce their risk of harm in the short term.

Inter-Vehicular Communications (IVC) are considered a promising technological approach for enhancing transportation safety and improving highway efficiency. Previous theoretical work has demonstrated the benefits of IVC in vehicles strings. Simulations of partially IVC-equipped vehicles strings showed that only a small equipment ratio is sufficient to drastically reduce the number of head on collisions. However, these results are based on the assumptions that IVC exhibit lossless and instantaneous messages transmission. This paper presents the research design of an empirical measurement of a vehicles string, with the goal of highlighting the constraints introduced by the actual characteristics of communication devices. A warning message diffusion system based on IEEE 802.11 wireless technology was developed for an emergency breaking scenario. Preliminary results are presented as well, showing the latencies introduced by using 802.11a and discussing early findings and experimental limitations. © 2011 IEEE.
