The effects of a specific prompting sign on speed reduction
Accident Analysis & Prevention, 1987The purpose of this experiment was to determine whether a specifically worded prompting sign ("BEGIN SLOWING HERE") could reduce speeding where a highway entered an urban area with a residential speed limit. Speed measurements were obtained on vehicles at the start of the residential speed limit zone.

Speed Reduction in School Zones
1976The use of flashing beacons together with signing has become somewhat standard throughout the country to alert drivers to the presence of school children and to regulate vehicle speed in school zones. Yellow beacons, usually two flashing alternately, may be used with both warning signs and regulatory signs.

The Impact of Priming on Speed Reduction on a Ski Slope
The Journal of Primary Prevention, 2018We tested a field-adapted priming procedure (a technique used to subtly activate mental representations and guide behavior) on a ski slope, with the goal of reducing risk behavior in winter sports. At cableway stations, skiers were initially exposed eight times to a prevention poster displaying a logo and a "slow down" message.

Harmonic Reduction in Adjustable-Speed Synchronous Motors
IEEE Power Engineering Review, 2001Summary form only given, as follows. Adjustable-speed synchronous motors (ASSM) are very popular in high-power high-speed applications. The Chilean mining industry uses them in milling operations in ranges of several thousands hp. Although a high pulse number for the inverter would be beneficial, it never goes beyond 12, due to complicated connections.

Speed reduction on through roads in nordrhein-westfalen
Accident Analysis & Prevention, 1992The paper describes a program of experiments for speed reduction on 28 through roads in Nordrhein-Westfalen. In the process, different measures of construction, design, and traffic control were examined to determine their usefulness to reduce speed and to improve road safety. The need for systematic evaluation of a catalogue of measures partly resulted

The duration of speed reductions attributable to radar detectors∗
Accident Analysis & Prevention, 1993The duration of speed reductions attributable to radar detector use was observed. When the entire traffic stream was exposed to police radar, the proportion of vehicles traveling more than 10 mph over the speed limit dropped initially from 42% to 28%, but by one mile after exposure, this percentage had already increased to 38%.

Evaluating the Speed Reduction Effectiveness of Speed Bump on Local Streets
ICCTP 2011, 2011The effects of speed bump on reducing vehicle speeds are still unclear though they have been extensively used on local streets in China. The primary objective of this paper is to evaluate the impacts of speed bump on speed reduction on local streets. The research team measured 3,000 vehicle speed observations at 15 locations around speed bumps on local

Feature Reduction to Speed Up Malware Classification
2012In statistical classification work, one method of speeding up the process is to use only a small percentage of the total parameter set available. In this paper, we apply this technique both to the classification of malware and the identification of malware from a set combined with cleanware.

Evaluation of the Speed Reduction Effects of Automated Speed Enforcements on Freeways
ICCTP 2011, 2011Automated speed enforcement (ASE) has been considered an effective approach to reduce speeding on freeways. Until recently, however, impacts of ASE on vehicle speeds on freeways are still not clear in China. The primary objective of this study is to evaluate the effectiveness of ASE in reducing vehicle speeds and speeding on freeways.

Effectiveness of Speed-Monitoring Displays in Speed Reduction in School Zones
Transportation Research Record: Journal of the Transportation Research Board, 2006Speeding is one of the major causes of the frequent and severe traffic accidents that occur in school zones. Two field studies were conducted to assess the short-term and long-term effectiveness of speed-monitoring displays (SMDs) for speed reduction in school zones.
