[Are speed cameras able to reduce traffic noise disturbances? An intervention study in Luebeck].
Disturbance by traffic noise can result in health problems in the long run. However, the subjective perception of noise plays an important role in their development.

Drivers' behavioral responses to combined speed and red light cameras.
Numerous signalized intersections worldwide have been equipped with enforcement cameras in order to tackle red light running and often also to enforce speed limits. However, various impact evaluation studies of red light cameras (RLCs) showed an incr

Behavioural effects of fixed speed cameras on motorways: overall improved speed compliance or kangaroo jumps?
The present study evaluates the speed effects of fixed speed cameras on motorways. Two locations with speed cameras were extensively examined in a quasi-experiment: (1) a two-lane motorway and (2) a three-lane motorway, each with a posted speed limit

Overt vs. covert speed cameras in combination with delayed vs. immediate feedback to the offender.
Speeding is a major problem in road safety because it increases both the probability of accidents and the severity of injuries if an accident occurs. Speed cameras are one of the most common speed enforcement tools. Most of the speed cameras around t

To brake or to accelerate? Safety effects of combined speed and red light cameras.
The present study evaluates the traffic safety effect of combined speed and red light cameras at 253 signalized intersections in Flanders, Belgium that were installed between 2002 and 2007.

Effects of vehicle speed on flight initiation by Turkey vultures: implications for bird-vehicle collisions.
The avoidance of motorized vehicles is a common challenge for birds in the modern world. Birds appear to rely on antipredator behaviors to avoid vehicles, but modern vehicles (automobiles and aircraft) are faster than natural predators. Thus, birds m

Stretching is often part of the warm-up routine prior to athletic participation; however, controversial evidence exists on the effects of stretching on countermovement jump (CMJ) and sprint performance. Additionally, analysis of variability between r

Impact characteristics of a vehicle population in low speed front to rear collisions.
Rear impact collisions are mostly low severity, but carry a very high societal cost due to reported symptoms of whiplash and related soft tissue injuries. Given the difficulty in physiological measurement of damage in whiplash patients, there is a si

Adjustments of speed and path when avoiding collisions with another pedestrian.
When walking in open space, collision avoidance with other pedestrians is a process that successfully takes place many times. To pass another pedestrian (an interferer) walking direction, walking speed or both can be adjusted. Currently, the literatu

Do Juvenile Curfew Laws Reduce Underage Drinking?
Although not originally enacted to deter the problem of underage drinking in the United States, one set of laws that may influence this behavior is juvenile curfew laws. This research asked the following: (a) What is the effect of enacting a juvenile
