Vehicle speed is one of main parameters describing
driver behavior and it is of paramount importance as
it affects the travel safety level. Speed is, in
turn, affected by several factors among which
in-vehicle vibration may play a significant role.
Most of speed reducing traffic calming
countermeasures adopted nowadays rely on vertical
vibration level perceived by drivers that is based
on the dynamic interaction between the vehicle and
the road roughness. On the other hand, this latter
has to be carefully monitored and controlled as it
is a key parameter in pavement managements systems
since it influences riding comfort, pavement damage
and Vehicle Operating Costs. There is therefore the
need to analyse the trade-off between safety
requirements and maintenance issues related to road
roughness level. In this connection, experimental
studies aimed at evaluating the potential of using
road roughness in mitigating drivers’ speed in a
controlled environment may provide added value in
dealing with this issue. In this paper a new
research methodology making use of a dynamic driver
simulator operating at the TEST Laboratory in Naples
is presented in order to investigate the
relationship between the driver speed behavior on
one hand, and the road roughness level, road
alignment and environment, vehicle characteristics
on the other. Following an initial calibration
phase, preliminary results seem fairly promising
since they comply with the published data derived
from scientific literature. |
