Deicing Performance of Road Salt
Transportation Research Record: Journal of the Transportation Research Board, 2014This paper describes the results of a field study designed to quantify the effects of various factors on the snow-melting performance of salt. Many tests were conducted in a realistic environment over two winter seasons, covering more than 70 snow events, with temperatures ranging from −14°C to 3°C and snowfalls ranging from ∼0.2 to 21.0 cm.

Boosting performance of road infrastructure
Built Environment Project and Asset Management, 2011PurposeSingapore's land transportation is governed by a comprehensive set of rules, regulations, operations and systems to ensure its effectiveness and efficiency. The Land Transport Authority (LTA) is the main agency in charge of road operations. Despite the LTA's best efforts, road related problems still surface every now and then.

Performance of Off-road Vehicles
2016Vehicle performance refers to the science of motioning of the vehicle in terms of transient performance (e.g. acceleration, braking, cornering) and those of steady-state performance criteria such as (power driveline losses, gross and net traction, vehicle aerodynamics).

Road Standards and Traffic Performance
Journal of Forestry, 1986The cost of constructing and maintaining transportation systems concerns foresters, public and private. In 1982, the USDA Forest Service budget for roads was $567 million. In 1985, the figure amounted to $613 million. A 1981 Forest Service directive called attention to problems arising because "roads are often built at too high a standard, which ...

Physiological Correlates of Female Road Racing Performance
Research Quarterly for Exercise and Sport, 1981Abstract The purpose of this study was to determine the relationship between female distance running performance on a 10 km road race and body composition, maximal aerobic power ([Vdot]O2 max ), running economy (steady-state [Vdot]O2 at standardized speeds), and the fractional utilization of [Vdot]O2max at submaximal speeds (% [Vdot]O2max ).

Physiological correlates to off-road cycling performance
Journal of Sports Sciences, 2005The aim of this study was to examine the relationships between maximal and submaximal tests for aerobic fitness and performance in an off-road cross-country circuit race. Thirteen competitive off-road male cyclists participated in the study. Peak oxygen uptake (VO2peak), peak power output, and lactate thresholds corresponding to 1 mmol x l(-1) above ...
