New Jersey's Teen Driver Decals Linked with Fewer Crashes

24.10.2012
Findings from a study conducted by CHOP researchers released today provide initial evidence that New Jersey’s Graduated Driver Licensing (GDL) decal requirement lowers crash rates among teen drivers with an intermediate license (i.e., probationary license).

The decal requirement, also known as Kyleigh’s Law, also supports the ability of police to enforce GDL provisions. In NJ, all novice drivers 16 to 20 years of age must display a reflectorized decal on the front and back of the vehicles they are operating.

Although decal provisions as part of GDL have been used in several countries for decades, their effectiveness had not yet been studied.

The study, which was funded by the Robert Wood Johnson Foundation, found in the first year after implementation of the law, the rate of police-reported crashes among intermediate drivers decreased 9 percent and the rate of GDL-related citations issued to intermediate drivers increased 14 percent.

"The rate of intermediate driver crashes significantly declined during the period after the decal requirement went into effect," says lead author Allison Curry, PhD, MPH, director of Epidemiology and Biostatistics at the Center for Injury Research and Prevention at CHOP.

"The number of crashes prevented is equivalent to the number of students attending a large high school. New Jersey youth and other road users are safer as a result of the decals."

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...

Im Focus: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
