A single statistic can strengthen public support for traffic safety laws

25.09.2014

Knowing the risk increased support of laws aimed at drunk driving and red-light running, among others

Public support for effective road safety laws, already solid, can be strengthened by a single number: a statistic that quantifies the traffic-related injury risks associated with a given law, according to a new study from the Johns Hopkins Center for Injury Research and Policy at the Johns Hopkins Bloomberg School of Public Health.

The study, published in the September issue of Accident Analysis & Prevention, surveyed 2,397 adults nationwide about their attitudes toward four types of road-safety laws — mandatory ignition interlock installation for people convicted of driving under the influence (DUI), the use of red-light cameras in school zones, a requirement that in-vehicle information entertainment systems be disabled when a car is moving and the mandatory use of bicycle helmets for children under 16.

After indicating their initial support or opposition for each law, respondents were given a statistic about the injury risk addressed by each law or the efficacy of the laws in reducing that risk. Afterward, respondents were asked again about their attitudes toward the laws.

The majority of survey respondents were initially either supportive or strongly supportive of each of the four laws. Nearly three out of four (74.8 percent) participants were in favor of the requirement that children under 16 wear bicycle helmets, and nearly as many (74.4 percent) supported mandatory ignition interlock installation for DUI offenders.

More than three out of five (61.4 percent) were initially in favor of a requirement that in-vehicle infotainment systems lock when a car is moving, and close to as many (58 percent) supported the use of red-light cameras in school zones.

For each of the four laws, support increased significantly after participants were given a statistic about related injury risks or how each law would reduce those risks.

Nearly a third (30.7 percent) of respondents became more supportive of the law pertaining to in-vehicle infotainment systems; close to one in four (22.2 percent) increased their support for the red-light camera law, and one in five (20 percent) became more supportive of both the bicycle helmet and ignition interlock laws.

"We are very encouraged by the results of this study, the benefits of which have potential for broad application," says Katherine Clegg Smith, PhD, lead author of the study and faculty member at the Johns Hopkins Center for Injury Research and Policy.

"In our analysis, research-informed evidence considerably increased public support for safety initiatives that are known to make a difference. Knowing that scientific evidence influences public opinion provides support for continuing to generate and share research on injury prevention policies to better inform the public about key safety issues."

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
