Traffic Accidents Characteristics in 4/2D and 4/2UD Road Type (Case Study: Nguling – Gempol Highway Section)
Abstract
Road safety is one of the efforts in reducing the number of accidents on the
highway. In terms of transportation, especially highways, the potential for traffic
accidents is very high. In 2018 cases of accidents that occurred in Pasuruan
Regency reached 868 cases. That number increased 7% from 2017 which reached
809 accident cases (Detik News, January 1, 2019). Especially on the Nguling -
Gempol Highway section in Pasuruan Regency which is a segment with a high
accident-prone rate. On the Nguling - Gempol Highway section, there are roads
with a median and no median. With the increasing number of accidents in
Pasuruan Regency, comprehensive road safety factors must be considered in all
aspects, namely the facilities and infrastructure aspects.
Based on this problem, it is necessary to compare the characteristics of
accidents on 4 / 2D and 4 / 2UD road types. Direct survey to the location to find
out the existing condition and spotspeed of the vehicle and also accident data 5
years back to find out the accident rate on that section. This study reviewed 19
road segments, namely 11 segments with 4 / 2D road types and 8 road segments
with 4 / 2UD types based on village boundaries on Jalan Raya Nguling - Gempol,
Pasuruan Regency.
Based on the results of the study, accident characteristics of 7 variables
based on the type of road 4 / 2D and 4 / 2UD that have been tested by T were
found that based on the type of road showed Sig (2-tailed) of 0.787 which means
there were no significant differences, based on the severity of the shows Sig (2-
tailed) died in the world at 0.925, seriously injured at 0.108 and minor injuries at
0.407 which means there is no significant difference, based on the value of EAN
(weighting of accident numbers) shows Sig (2-tailed) died at 0.925, seriously
injured of 0.108 and minor injuries of 0.407 which means there is no significant
difference, based on the day of the accident shows Sig (2-tailed) Monday was
0.109, Tuesday was 0.883, Wednesday was 0.366, Thursday was 0.741, Friday
was 0.622, Saturday was 0.015 and Saturday was 0.015 and Sunday was 0.015 of
0.055 which means that there are significant differences, namely on Saturdays,
based on the type of vehicle indicated Sig (2-tailed) motor vehicles by 0.006, light
vehicles by 0.318 and heavy vehicles by 0.052 which means that there are
significant differences in motor vehicles, based on the time of the accident shows
the Sig (2-tailed) in the morning by 0.509, day by 0.255 and night equal to 0.007
which means there is a significant difference that is at night and Based on the
speed of the moment (spotspeed) shows Sig (2-tailed) of 0.178 which means there
is no significant difference.
From the results that have been obtained it can be concluded that the
comparison of accident characteristics on the type of road 4 / 2D and 4 / 2UD on
the Nguling - Gempol road section on the seven factors that cause the accident
that has been tested shows that there are three factors causing the accident that
there are differences significant, based on the type of vehicle, the time of accident
and the day of the accident while the other variables have no significant
difference.
