In 1987 the federal government permitted states to raise the speed limit on their rural interstate roads, but not on their urban interstate roads, from 55 mph to 65 mph for the first time in over a decade. Since the states that adopted the higher speed limit must have valued the travel hours...

In der Diskussion über städtische Luftverschmutzung und Geschwindigkeitsbegrenzungen auf Autobahnen besteht ein Mangel an evidenzbasierten Argumenten, was die Debatte immer wieder blockiert. Bei der Bewertung von Grenzwerten bzw. angedachten Maßnahmen wie Tempolimits sollten kausale...

We study the impact on road safety of one-day massive speed limit monitoring operations (SLMO) accompanied by media campaigns that announce the SLMO and provide information on the dangers of speeding. Using register data on the universe of police reported accidents in a generalized...

Uniquely amongst industrialized countries worldwide, Germany does not impose a general speed limit on highways. This is different in the Netherlands, where a limit of 130km/h is implemented.

Law enforcement officers are allowed to exercise a significant amount of street-level discretion in a variety of ways.
