This ideal path still has validity today provided the speed is very low and the trailer is unloaded. During a common phenomenon of snaking or fishtailing, the trailer sways back and forth in relation to the prime mover centreline axis. Often regarded as the nightmare of caravanning, the action does not follow the tractrix curve but follows a shorter path to the common centreline of prime mover and trailer. This paper explores the shorter path in response to a tyre reaction to centripetal force causing slip steer. An example derived by drafting progression steps to \u0000how quantitatively that speed causes early cross-over carrying more energy into the next fishtailing phase is presented. It is believed the inclusion of slip steering to modify a tractrix curve is a novel development.","PeriodicalId":43503,"journal":{"name":"Journal of the Australasian College of Road Safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44586658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Promoting of safe cycling practices regardless of location has utility and warrants discussion within the disciplines of travel medicine and road safety. It is recommended before cycling overseas that individuals familiarise themselves with road rules, right of way, cycling infrastructure and the general conduct of other cyclists. Route planning will also likely be faciliated by this familiarisation and enable strategic sightseeing opportunities.","PeriodicalId":43503,"journal":{"name":"Journal of the Australasian College of Road Safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46551794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Little is known about the processes that these practitioners use to make these decisions, and how current guidelines assist in making determinations about driving capacity. A short survey was completed by 42 practitioners. The results of the survey supported previous findings that practitioners do not feel comfortable with making the decision regarding fitness to drive for people with dementia. Practitioners relied largely on self-report or informant information regarding current driving practices. Although practitioners reported that the level of cognitive functioning was the most important factor in determining safe driving, only 25% of practitioners employed cognitive assessments. Whilst the vast majority of practitioners were aware of the fitness to drive guidelines, over half did not find them to be sufficient in enabling determinations of driving capacity. Due to this, almost all practitioners reported that they believe they have missed cases of unsafe driving in this population with over 85% endorsing the need for a more objective tool. Significantly, over three quarters of practitioners reported that they have never received training on how to make fitness to drive decisions. Given that the current driver licensing system for people with dementia depends on medical fitness to drive reviews, the lack of confidence by practitioners regarding making fitness to drive decisions can have a detrimental impact on both the safety of the individual drivers, but also the community as a whole.","PeriodicalId":43503,"journal":{"name":"Journal of the Australasian College of Road Safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43516027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A survey was conducted with a relatively large (n = 1206) random sample of children aged 7 to 9 years old, drawn from 24 selected schools in six states in Malaysia based on the highest numbers of crash cases. Analysis of one-way ANOVA revealed a statistically significant difference in safe pedestrian behaviours between different ages. Post hoc comparisons using the Tukey HSD test indicated that the mean score of safe pedestrian behaviours for 7-year-old children was significantly higher than that of 8-year-old children (p = .004) and 9-year-old children (p = .021). No statistically significant difference was revealed between the 8-year-olds and 9-year-olds (p = .859) at the 0.05 level. Although many children reported safe pedestrian behaviours, low levels of certain safe pedestrian behaviours were also reported – less than 30% of the children aged 7 to 9 reported to ‘always’ wear bright clothes, walk against the traffic, and wave at the drivers to cross the road. In addition, a small percentage (9.9-13.6%) of children aged 7 to 9 also reported to ‘always’ wear dark clothes at night, cross the street between parked cars, and run to cross the road. These findings may inform programs to improve children’s safe pedestrian behaviours.","PeriodicalId":43503,"journal":{"name":"Journal of the Australasian College of Road Safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45240578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Safety-related incidents associated with secondary task engagement were also examined. Results revealed that driver engagement in secondary tasks was frequent, with drivers engaging in one or more secondary tasks every 96 seconds, on average. However, drivers were more likely to initiate engagement in secondary tasks when the vehicle was stationary, suggesting that drivers do self-regulate the timing of task engagement to a certain degree. There was also evidence that drivers modified their engagement in a way suggestive of limiting their exposure to risk by engaging in some secondary tasks for shorter periods when the vehicle was moving compared to when it was stationary. Despite this, almost six percent of secondary tasks events were associated with a safety-related incident. The findings will be useful in targeting distraction countermeasures and policies and determining the effectiveness of these in managing driver distraction.","PeriodicalId":43503,"journal":{"name":"Journal of the Australasian College of Road Safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89361601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I quantified the extent of phone use by pedestrians over seven hours at each of the 10 signalised crossings in central Hobart. Of the 16,032 people counted, 12.4% of pedestrians were using phones: 4.6% were reading or typing on their phone, 2.3% were talking and another 5.5% were listening to headphones. The latter figure will be an underestimate because of the difficulty of seeing headphones obscured by hats and long hair. At the busiest sites at two ends of a pedestrian mall, there were as many as 155 and 158 people in a one hour period looking down at their phones to read or type. Fortunately these two roads had slow moving vehicle traffic, meaning consequences of crashes would likely be minor. However, four of the sites crossed wide, 50kph, arterial roads, so a combination of responses will be needed to lower crash risk, including education, enforcement and consideration of safe road speeds.","PeriodicalId":43503,"journal":{"name":"Journal of the Australasian College of Road Safety","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77654820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
