Table 3.2 shows that the average distance traveled for those two groups
of driver was 6240.44 km. There was a noticeable gap in between the minimum
distance travelled accounting for only 17.93 km while the maximum distance
travelled was a whopping 16347.56 km. Driving score average did not vary
much as the differences between both the groups was only 5.41 %. But in
contrast to a study by (Mishra, B., Sinha Mishra, N. D., Sukhla, S., & Sinha, A.,
2010) which stated long distance travel were found to be associated with high
percentage of Road Traffic Accident (RTA), driving score for short haul group
attributed to the lowest score with only 18.12% which translates into risky
driving.
To explain and support the argument for the differences in driving score
between long and short haul drivers, independent t-test was used.
Independent t-test was analyzed using r software and below is the result:

Two Sample t-test
t = 1.0412, df = 22.861, p-value = 0.3087

From the analysis, we can see that the independent sample t-test analysis
showed that p-value is 0.3087 and we accept H null. Hence, we can conclude
that there is no difference in driver score mean between long haul and short
haul drivers. This shows regardless of short or long trips, drivers risk factors
has been brought to a similar level due to the usage of ADAS. It is assumed
that short-haul group risk factors remain lower than the long-haul group.

4. Discussion and Conclusion
In this study we investigated the usage of ADAS in commercial vehicle that
travels short & long haul. The purpose of the study is to observe, and validate
the assumptions that long distance driver has much higher tendency in
dangerous driving behaviour. In addition, the effect of ADAS in improving the
driving behaviour on those drivers, have been observed.
The Malaysia Driver Score (MDS) is a scoring model to assess and score
a driver’s driving characteristics through the use of In-Vehicle Telematics
Device (IVTD), which is in our case, ADAS was used. MDS can be an effective
tool to cultivate, nurture and promote safe driving behaviour among
Malaysian drivers by providing objective and real-time driving behaviour
assessment. Drivers can obtain their overall driving score and improve their
driving by examining the risky driving behaviours as identified by MDS. By
improving the overall driving behaviour, it is expected that the number of
crashes, especially those due to driver errors can be further reduced.
From the study, it is seen that there are no noticeable difference of MDS
score between long haul and short haul group. ADAS is known to help to
reduce the risk of the two haul group in dangerous driving, thus reducing the
