ANALISA KINERJA KENDARAAN BERAT PADA TURUNAN RUAS JALAN PERINTIS KEMERDEKAAN SEMARANG
ABSTRACT: Semarang city has a
role as a place of transit point for heavy vehicles which transport logistics
to rest because it is in the middle of the roads Pantura Java. Perintis
Kemerdekaan road located in the south of Semarang is artery road primary so
that all types of many vehicles from the middle roads passing through the road
with high speed. The conditions of Perintis Kemerdekaan road in the form of
uphill and downhill that sharp enough between 4 % until 7.7 % as long as 2
kilometers. At the end of a downhill, truck must stop on Karangrejo signal
intersection. The driver of a heavy vehicles had difficulty in passing downhill
of Perintis Kemerdekaan road so many accident happens because the brake
failure. Study of this research is analyzing the performance of heavy vehicles
passing through on downhill in Perintis Kemerdekaan road. Methods used in
research is to do a survey of travel time to get spot speed in each type of the
truck and the speed of change when passing through the downhill. The result of
the analysis used to calculate the rate of deceleration and braking distance
required in each type of truck. The result shows that decelaration the highest
occurred for three research locations, for truck with machine capacity 100-130
HP is 2,337 m/s2. While for truck with machine capacity 190-225 HP, the highest
average decelaration happened is 2,059 m/s2. The deceleration on both kind of
truck it is still under the deceleration maximum allowed is 3,41 m/s2 as the
maximum limit of the brake. The braking distance is required so that truck
capable of being stopped in Karangrejo intersection, for truck with with
machine capacity 100-130 HP along 94,884 meters. While for truck with machine
capacity 190-225 HP, the braking distance necessary along 87,900 meters. While the
distance existing from the line stopping of signal intersection up to a start
braking point on the final slope as long as 250-300 meters.
