Allen et al. [2] studied on the shocks and the impacts encountered on small high-speed craft
exceed the limits set for safe working practice according to current standards. They set out to
highlight the vibration dose values that can be expected during typical transits onboard high-
speed craft and attempts to clarify some of the controversy currently surrounding vibration dose
measurement in such circumstances. Dawkins et al. [3] investigated the effectiveness of using
fractals for generating artificial terrains which can be used for vehicle simulations. Shoop et al.
[4] explored a methodology that could quantify the impact of various vehicles, tires, driving
speeds and maneuvers on the snow road conditions. Basic maneuvers were used to isolate the
impact of turning, acceleration, braking and speed using spirals, circles, and straight-line testing
on a flat, smooth snow pavement. Fallah-Fini et al. [5] discussed a dynamic efficiency
measurement model for evaluating the performance of high way maintenance policies where the
inter-temporal dependencies between consumption of inputs and realization of outputs were
explicitly captured. Chan et al. [6] utilized the Tennessee Pavement Management System and
Accident History Database to investigate the relationship between accident frequency and
pavement distress variables. Shah et al. [7] evaluated two methods for priority ranking of road
maintenance; ranking based on subjective rating and ranking based on economic indicator.
Erdogan et al. [8] focused on the development and experimental evaluation of a novel adaptive
feed forward vibration cancellation based friction estimation system. Nila et al. [9] focused on
the hydrodynamic impact of bodies onto the water surface which is a problem of great
importance in the design of off-shore and naval structures (wave energy converters, off-shore
platforms, high speed boats, etc). Wines [10] focused on an issue for high speed craft that they
in general are subject to high levels of vibration. Such vibrations may be harmful to the human
body on-board and may reduce the situational awareness. An 11m hull RIB has been
investigated experimentally for very high Froude numbers. Having recognized the problems that
will most likely occur in calm water and in waves, the actual RIB was instrumented and a series
of tests were conducted regarding vibration and maneuverability. Wertheim et al. [11] tested the
traditional assumption that sea sickness is uniquely provoked by heave motion characteristics,
with pitch and roll movements being ineffective. In an experiment with a ship motion simulator,
subjects were exposed to pitch and roll motions in combination with rather weak heave motions
that have no motion sickness inducing potential.

Turner and Griffin [12] identified personal and environmental factors influencing individual
susceptibility to motion sickness during road transport. A questionnaire survey of 3256 coach
travelers was conducted. Diaz et al. [13] presents the design of a monovariable robust controller
with quantitative feedback theory (QFT) for reducing the vertical movement on a high-speed
ferry. Kim et al. [14] investigated the response of the human body to the amounts, frequencies,
directions, and exposure times of exerted forces. Processes have been developed to standardize
these factors, and the typical examples are ISO 2631-1 and BS 6841, which are related to
whole-body vibration and ISO 5349-1, which is related to hand transmitted vibration. Ahn [15]
focused on discomfort of vertical whole-body shock-type vibration in the frequency range of 0.5
to 16 Hz. In this experimental study, various shock signals were systematically produced using
the response of a one degree-of-freedom vibration model to hanning-windowed half-sine force
input. Zhao and Schindler [16] investigated the evaluation of the WBV (Whole-body-vibration)
exposure using ISO 2631-1 and ISO2631-5 standards and the results were compared in their
study. Turkay and Akcay [17] utilized the response of the vehicle to profile imposed excitation
with randomly varying traverse velocity and variable vehicle forward velocity with using the
quarter car model. Misol et al. [18] investigated the different active structural acoustic control
(ASAC) concepts for the reduction of interior noise in an automobile passenger compartment.
For the control experiments, a medium-class test car was used, which had been equipped with
