Highest average rate of US road deaths on Independence Day

03.02.2005


[Temporal factors in motor vehicle crash deaths Injury Prevention 2005; 11: 18-23] / [Heat related deaths in young children in parked cars: an analysis of 171 fatalities in the United States, 1995-2002 Injury Prevention 2005; 11: 33-37]

More than 100 people die on US roads every day, but there is definitely a seasonal trend, with the highest average death toll on July 4, Independence Day, reveals research in Injury Prevention. Researchers from the Insurance Institute for Highway Safety analysed data from the national Fatality Analysis Reporting System for the years 1986 to 2002 to see if they could identify any trends in the timing and severity of car crashes.

They compared days with relatively high numbers of car crash deaths with the two days exactly one week before and week afterwards, in a bid to rule out any anomalies in the figures. The analysis showed that on average 117 people die on US roads every day, but the death toll ranged from 45 to 252 deaths on any one day. There were more road deaths during summer and autumn than during winter and spring, largely because of the increased volume of traffic on the roads, suggest the authors. There were more deaths in August than any other month, and more deaths from June to November than from December to May. The fewest deaths occurred in January and February, but far fewer journeys were made during these months.



Specific days stood out. The average toll of road deaths was higher on Independence Day, July 4, than on any other day of the year across the whole study period. Alcohol tended to be involved in a higher proportion of the Independence Day deaths than on other days. New Year’s day racked up the highest number of pedestrian deaths from car crashes and ranked fifth for the highest number of daily deaths, overall. Again, alcohol consumption proved an important factor. Half of all the deaths on this day occurred between midnight and 6 am. More deaths occurred on Saturday than any other day of the week and the peak time for fatalities was between 5 and 6 pm.

A second study in the journal assessed the numbers of children under the age of 5 who died in parked cars as a result of heat. Between 1995 and 2002, 171 deaths were recorded in this age group. Around one in four of the children had managed to climb into an unlocked car by themselves, but almost three quarters of the children had been left in a car by adults. One in four of the adults were aware that they had left a child in a car, but half either did not realise, or simply forgot, that they had done so.

Almost half of the children were being looked after by an adult as part of childcare. Of these 54 children, 32 had been left by family members who planned to take them to childcare, but forgot and went to work instead. The remainder were left in vehicles by childcare providers or drivers.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
