Smartphones provide serious threat to driving safety

Research into the risks posed by the use of smartphones by drivers has revealed extremely worrying results. An international study into this field has shown that using cellphones to send texts while at the wheel can deliver significant risks for vehicle occupants as well as others. The study has shown that sending texts while at the wheel presents a similar safety risk to being 25% over the legal limit for alcohol in the bloodstream. In addition the study has shown that using hands-free telephone technology

Research into the risks posed by the use of smartphones by drivers has revealed extremely worrying results. An international study into this field has shown that using cellphones to send texts while at the wheel can deliver significant risks for vehicle occupants as well as others. The study has shown that sending texts while at the wheel presents a similar safety risk to being 25% over the legal limit for alcohol in the bloodstream. In addition the study has shown that using hands-free telephone technology may not reduce risks, with the intensity and complexity of the conversation being a critical factor. The study has been carried out jointly by a number of universities and institutes. These include the University of Barcelona and from Australia; Wollongong University, Victoria University and Swinburne University of Technology.

The research compared how mobile phone impacted on driving ability against known data on alcohol use by those behind the wheel. The researcher assessed a group of drivers under laboratory conditions using simulation technology. Factors such as excess speed, reaction times for braking, changes in speed and lane changes were monitored under the tests, with drivers being assessed when not using a phone, using a hand-held device to send texts and using a hands-free system for conversation. The research also compared the effects of a simple conversation with that of a more complex discussion. A further step was to provide the test subjects with controlled quantities of alcohol to meet three set blood alcohol levels, and then carry out a series of tasks using a driving simulator. The data revealed that driving ability dropped significantly when the test subjects were using cellphones to send texts or to carry on complex conversations.

What the study shows is that the human brain does have limitations with regard to multi-tasking and this applies to both males and females alike. With regard to the hands-free technology, more research will be required to determine the difference between discussions that are involving and require greater concentration than simpler conversations. Attempting construct a legal framework around what type of discussion would be permissible for drivers using hands-free technology may be complex however and it would seem likely that simple bans may be easier to implement.

The issue of distracted driving is a growing problem around the world and this research highlights that a broader understanding of the risks as well as greater enforcement and much tougher penalties are required.

    The modern automobile offers massive gains in safety over earlier generation vehicles. Occupant protection levels have been improved due to crash testing regimes that have ensured vehicles will not collapse catastrophically in the event of an impact. Braking systems are more effective and reliable, with ABS preventing skidding in wet weather conditions. The prospect of autonomous vehicles in the near future offer further safety gains to come. But right now, there is a problem. Too much technology is bein

    How best is it possible to assess the state of concrete in a road pavement, bridge deck or tunnel wall? One of the most reliable ways is to take a core of concrete from the structure to analyse and test in the laboratory. One downside to this method is that doing the test creates weak points in the structure that must then be repaired. Another is that the frequency of such cores cannot be too great – so it is possible that some problem areas will be missed. New technologies from the world of geospatial eng

    Worrying data has been revealed by a study of bus drivers in Nigeria’s mega-city and commercial centre, Lagos. The research revealed that 39% or 781 of the 2,002 bus drivers tested drive while under the influence of alcohol. Also revealed was the fact that 940 of the drivers have visual impairments, with 13% having been given special glasses. And 22% of the drivers, 441, tested positive for either marijuana or cocaine use (and in some instances both). In addition, 30% of the drivers (601) were revealed to b

    Official UK Government figures reveal that convictions for traffic offences in England and Wales have been steadily increasing since 2013. Of concern is that there has been a 52% increase in convictions for dangerous driving in that period. There were guilty verdicts for 1.2 million traffic offences in 2006, according to an analysis of the data by IAM RoadSmart. The number of guilty verdicts for traffic offences then declined for seven years until 2014 when the total number of offences started rising again
