| 總結: | Road accident has become an alarming phenomenon across the country. Its
negative impact does not only include loss of lives but also affects the economy. Hence,
road safety assessment has become a crucial preventive measure. Several assessment
studies have been developed and implemented. However, they are mostly conducted in
the post-accident level, in which the accident has already taken place. A study using a
vehicle dynamic simulation is then proposed to assess the accident at the post-accident
level. In order to check its effectiveness, two accident-prone locations were chosen, its
road segments are then generated into a simulated environment. Several combinations
of the simulation parameters are then introduced to the simulation, such as road
geometries, road profile, road condition, vehicle type, and driving characteristic. The
outcome is then analyzed through visual observation and data analysis. Based on the
study conducted, the crash report data obtained from the accident-prone location has
almost similar output when the simulation parameter input matched with the crash data.
An apparent visual indication, such as a vehicle crashing event, can also be seen from
the simulation result. The vehicle dynamic data gives promising results by showing
prediction in the form of an erratic response before failing. The vehicle dynamic
response parameters are, namely, roll and lateral acceleration. It is concluded that this
road safety assessment method can successfully replicate the actual type of accident that
happens in the accident-prone location. Translating the actual road profile into a
simulation form can be considered successful since it can imitate the particular road
profile. The vehicle responses of roll and lateral acceleration can be used as a safety
assessment key indicator in identifying the point of failure of a road stretch.
Implementing similar methods to other road segments will result in the ability to find
the dangerous combination of parameters used as a countermeasure for the particular
road segment. |
