Speed limits may not be saving lives

23.06.2005


A new article publishing in the latest issue of Review of Policy Research examines the evolution and devolution of speed limit laws and their effects on fatality rates. The author did not find a significant increase in fatalities per miles driven after speed limit laws ceased to be national and states could, and some did, increase their highway limit to more than fifty-five miles per hour. "Automobile safety features and enforcement emerge as important factors in increasing highway safety; speed limits are far less important," author Robert O. Yowell explains.



Although speed limits bring to mind the notion of public safety, they were formed in the 1970s to combat a gasoline shortage. In the 1980s the focus shifted to public safety while some speed limit regulation devolved back to states; the maximum speed on rural interstates could be raised to 65 mph. In 1995 and involving some controversy, Congress returned all speed limit authority back to the states. Analysis of the highway deaths per mile driven after the 1974 nationalization of the maximum highway speed indicates an initial greater decline in deaths than had been the trend, but the long-term decreasing trend reemerged following the shock. Dr. Yowell’s research finds others reasons besides speed for the long-term trend of increased highway safety. (From 1968 to 1991, the fatality rate per 100 million declined by 63.2%.) Technical progress in car manufacturing, increased use of seat belts by drivers and passengers, an increase in the minimum legal drinking age, and the general maintenance of roads all affect this rate.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
