A road intersection is a point where various movements in different directions meet.
Road intersections have an important role in ensuring the smooth flow of traffic.
There are 2 (two) types of intersections, namely signalized intersections and
unsignalized intersections, signalized intersections are intersections that have
traffic signaling devices in the form of traffic lights, while unsignalized
intersections are intersections that do not have signaling devices. Perintis
Intersection is one of the unsignalized intersections in Purwokerto which is a
meeting between Perintis Kemerdekaan street north (major), Situmpur street
(major), Perintis Kemerdeka street south (minor) and Kalibener street Gg.1
(minor). Initial observations showed that these intersections are often congested,
especially during peak hours. PKJI 2014 is used as a reference in this study, data
collection is done through traffic surveys to obtain intersection performance in the
form of traffic volume (Q), capacity (C), degree of saturation (DJ), delay (T), and
queuing opportunities (Pa). The results of the intersection analysis obtained the
highest traffic volume occurred at 09.00 - 10.00 WIB on Wednesday amounting to
2447 skr/hour. With a capacity (C) of = 4081,76 skr/hour, degree of saturation (DJ)
= 0.61, total delay (T) = 11.27 seconds/skr, and queuing opportunities (Pa) = 16-
33%, with the level of service in category C with moderate information. Meanwhile,
for the performance of the intersection in 2028, the volume of traffic flow obtained
was (V) = 3132.8 skr/hour with a degree of saturation (DJ) = 0.77, total delay (T)
= 13.88 seconds/skr, and queuing opportunities (Pa) = 24-48%, with the level of
service in category D with less information.
