Abstract

This paper reviews the effect of Advanced Driver Assistance System (ADAS) on driver’s

behaviour who drive commercial vehicles for both the long haul group and short haul group.

It is known that for the drivers that drives long distance, the exposure to negligent driving

behaviour such as sudden braking and tendency of speeding are higher compared to the

short distanced drivers due to reduced focus and fatigue

ADAS was used as an instrument to measure various data points that makes up the driving

behaviour. ADAS helps in improving the driving style by alerting the drivers whenever a

dangerous driving behaviour is detected thus helping the driver to correct the behaviour

The driver’s behaviour is measured using the Malaysia Driver Score (MDS) which was

published by MIROS

Introduction

It is commercially known that Advanced Driver Assistance System(ADAS) is proven to significantly

reduce the number of road accidents in general. A recent study done by MIROS also establishes

that driver behaviour of passenger vehicles fitted with ADAS shows greater improvement than

those without the device, in terms of lower number of logged incidents.

Road accidents may result from human factors, environment and/or design of roads and

vehicles factors. However, human factor often plays the greatest role in causing road accidents

Human factor can be measured using the driver score model which will help to determine risk

profile of drivers -whether the driver falls in the good score or a bad score band according to

their driving behaviour

Research objective of this paper is to prove differences in driver score between long haul driver

and short haul driver group. Scope of study for this analysis are three logistics companies based in

Klang Valley which trips covers both long haul and short haul travels across Peninsular Malaysia.

Malaysia Driver Score – to address risk associated with

driver’s behaviour on the road

A score between 1-100 that accesses a driver’s likelihood of getting into a collision

Caters to two different segments: Private Passenger Vehicles Commercial Vehicles

Speeding Forward Collision Warning (FCW)

Hard Braking Lane Departure Warning (LDW)

Hard Cornering Speeding (SPD)

Encompasses 3 predictive driving behaviour parameters (based on MIROS’s study) normalized against mileage travelled (km) that will help determine the different sets of risk profile of drivers

What is Malaysia Driver Score, MDS?

For the purpose of this study, independent t-test was used to ascertain the differences in driver score means for the two groups of driversThis research study uses secondary data as a method of analysis. Data set was obtained for one month period for trips and events for each vehicleIn total there were 33 drivers who did trips for the whole month of February 2019 from three logistics companies. These drivers were categorized into two groups; long haul and short haul drivers

Methodology

Independent Sample t-test

The independent sample t-test compares the means of two independent groupswhich in this study is long-haul and short-haul driver group in order to determinewhether there is statistical evidence that the associated population mean aresignificantly different. Below are the hypotheses for independent sample t-testused in this study:

Descriptive statistics for Driver Score

The event triggered by the two categories of drivers. Lane Departure Warning (LDW) was the

highest event triggered with 89% of the all event triggered, followed by Forward Collision Warning

(FCW) with 7% and the lowest event triggered was Speed (SPD) which accounted for 5%.

Results

The average distance travelled for those two groups of driver was 6240.44 km. There was a noticeable gap in between the minimum distance travelled accounting for only 17.93km while the maximum distance travelled was a whopping 16347.56 km

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 analysed 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

Results

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 chance of negligent driving

This finding shows that the long-haul driving group, especially, has significant benefit in using

ADAS as it lowers their risk factors to the same level as short haul drivers.

ADAS is known to help reduce the risk of the two haul group in dangerous driving, thus reducing

the chance of negligent driving. The ADAS alarm & notification system has helped to notify the

driver when dangerous or negligent driving behaviour is observed, and the drivers can use it to

retroactively correct their driving style within the trip.
