Speed Reduction Effects of Urban Roundabouts

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2009
Road safety is one of the most serious problems in road traffic in many countries, including the Baltic countries. One of the alarming issues in road safety is the safety on urban crossings.

Algorithm for Monitoring Emissions Based on Actual Speed of Ships Participating in the Korean Vessel Speed Reduction Program

open access: yesEnergies, 2022
The vessel speed reduction program (VSRP) was first introduced in the Port of Los Angeles in 2001 to improve air quality. In this study, an algorithm was developed to calculate ship emissions with a bottom-up approach based on ship activity using ...

Speed Optimization vs Speed Reduction: the Choice between Speed Limits and a Bunker Levy [PDF]

open access: yesSustainability, 2019
“Speed optimization and speed reduction” are included in the set of candidate short-term measures under discussion at the International Maritime Organization (IMO), in the quest to reduce greenhouse gas (GHG) emissions from ships. However, there is much confusion on what either speed optimization or speed reduction may mean, and some stakeholders have ...

Speed optimization versus speed reduction: Are speed limits better than a bunker levy? [PDF]

open access: yesMaritime Economics and Logistics, 2019
The purpose of this paper is to shed some light on the speed limit debate, and specifically to look into whether reducing speed by imposing a speed limit is better than achieving the same by imposing a bunker levy. This debate, along with the various issues of speed optimization versus speed reduction, is currently ongoing at the International Maritime

Speed reduction in aviation: A double dividend for decarbonization

open access: yesTransportation Research Interdisciplinary Perspectives
Aviation faces a structural paradox: five decades of efficiency gains have been absorbed by traffic growth, and absolute emissions continue to rise. Existing sector-wide decarbonization scenarios from ICAO and IATA rest almost entirely on Sustainable ...

Influence mechanism of visual perception of edge rate lines cycle length on driver’s speed

open access: yesTransport, 2021
It is known that the installation of edge rate lines can help reduce driving speed. Theoretically, higher edge rate density leads to higher perception speed, so as the effect of speed reduction.

Synergy Effect of Factors Characterising Village Transition Zones on Speed Reduction

open access: yesEnergies, 2021
There are various traffic calming measures that can be installed in village transition zones. So far, focus was placed on diversified use of pavement markings, amounts of horizontal deflection, shape of the installed chicanes or central islands, presence

Identification of the Determinants of the Effectiveness of On-Road Chicanes in the Village Transition Zones Subject to a 50 km/h Speed Limit

open access: yesEnergies, 2021
In recent years, in which a considerable increase in the road traffic volumes has been witnessed, traffic calming has become one the key issues in the area of road engineering. This concerns, in particular, trunk roads passing through small villages with

Effect of Lane Narrowing Implemented on an Urban Dual Carriageway on Speed Reduction and Acoustic Environment

open access: yesBuildings, 2021
The on-going growth in the use of motor vehicles leads to a number of traffic safety problems. Therefore, various traffic calming measures are applied to increase traffic safety in built-up areas. Lane narrowing is one of the techniques used to influence
