The impact of vessel speed reduction on port accidents

Accident Analysis and Prevention, 2019
Reduced-speed zones (RSZs) have been designated across the world to control emissions from ships and prevent mammal strikes. While some studies have examined the effectiveness of speed reduction on emissions and mammal preservation, few have analyzed the effects of reduced ship speed on vessel safety.

Effectiveness of Speed-Monitoring Displays in Speed Reduction in School Zones

open access: yesTransportation Research Record: Journal of the Transportation Research Board, 2006
Speeding 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.

Effect of Wind on Operating-Cost-Based Cruise Speed Reduction for Delay Absorption

open access: yesIEEE Transactions on Intelligent Transportation Systems, 2013
En route speed reduction can be used for air traffic flow management (ATFM), e.g., delaying aircraft while airborne or realizing metering at an arrival fix.

Benefit of speed reduction for ships in different weather conditions

open access: yesTransportation Research, Part D: Transport and Environment, 2020
Currently, the shipping industry is facing a great challenge of reducing emissions. Reducing ship speeds will reduce the emissions in the immediate future with no additional infrastructure.

On the Caching Schemes to Speed Up Program Reduction

ACM Transactions on Software Engineering and Methodology, 2023
Program reduction is a highly practical, widely demanded technique to help debug language tools, such as compilers, interpreters and debuggers. Given a program P that exhibits a property ψ, conceptually, program reduction iteratively applies various program transformations to generate a vast number of variants from

Speed heterogeneity and accident reduction in mixed traffic

International Journal of Injury Control and Safety Promotion, 2023
Various studies have investigated the relationship between speed and accidents using different definitions of speed variation. This research considers the speed in mixed traffic as heterogeneous based on the vehicle categories. This research aims to develop a traffic safety model with speed heterogeneity as expressed in accident modification factor ...

The effects of a specific prompting sign on speed reduction

Accident Analysis & Prevention, 1987
The 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

1976
The 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.
