PERENCANAAN ALAT PEMBERI ISYARAT LAMPU LALU LINTAS (APILL) PADA PERSIMPANGAN JALAN PULAU GALANG, JALAN TAMAN PANCING DAN JALAN TUKAD BARU
No full textABSTRACT
The junction of Pulau Galang streets, Jalan Pancing streets and Tukad Baru streets
is one of the intersections that traffic flow is quite solid. If seen from the congestion that
often occurs at this intersection, it can be seen that it needs an application of Traffic
Management, the installation of traffic lights (APILL). Therefore, the purpose of writing
this final task, among others, is to analyze the performance of intersection intersection
(current state) and plan traffic management using traffic light.
To analyze the performance of the intersection and to plan the setting of the
intersection, first, there are surveys to get incoming data. The data can be primary data
obtained directly from the source, or secondary data obtained not from the source directly,
for example data obtained from relevant agencies. Analysis data were used the method of
Manual Capacity Jalan Indonesia (MKJI, 1997).
From the analysis result, it can be found that the performance of intersection at peak
hour of day and afternoon, has the capacity (C) peak at 2566 smp/hour and the peak of
afternoon 2460 smp/hour, the saturation degree (DS) at peak hour of 0.96 and peak
afternoon hours 1, the average delay of the intersection (D) at the peak hour of 18.35
sec/pc, and the peak hour of afternoon 20 second/smp, the queue probability (QP%) at the
peak hour of 73 - 36% afternoon, and the peak hour of the afternoon 79 - 40%, service
level C for peak hour day and afternoon. To fix and overcome the problem at the
intersection then the next thing is done planning the traffic signs (traffic light). The
selected intersection setting type is an intersection setting with a two-phase signal, since
the delay is relatively small, entering level B at the service level service. Compared with
the three-phase signal regulator with the initial green determination on the major or main
road approach and the four-phase signal arrangement with the current departing one by
one on each approach, the service level is greater than the two-phase signal setting.
