ANALISIS DAN OPTIMASI SIMPANG BERSINYAL SEMI KOORDINASI DENGAN MENGGUNAKAN SYNCHRO 7.0
ABSTRACT: The change of used
areas in Siliwangi road, from settlement to be the centre of business –
service, industrials and office, will appear traffic movement in Krapyak and
Tol Krapyak – Jatingaleh intersection. Moreover there will be some problem on
traffic phenomena as traffic jam, time of delay, air pollution that increase,
accident and other traffic problem that will cause lose time, fuel use, and
cost. This study aims to analyzed the performance of Krapyak intersection and
Tol Krapyak – Jatingaleh intersection, it should be changed the traffic
management and geometric research to minimized the traffic jam and air
pollution on both intersection. The pattern of the movement of the road beside
both intersection can be obtained by using origin – destination matrix (ODM).
The advantage of this method in which the vehicle volume and the value of
obstacle in each intersection, the pattern traffic movement can be gained. Of
course it will minimized the cost, time, human resources. The performance of
the intersection will be measure and analyzed using Synchro 7.0 from America.
The advantage of this program is able to stimulate planning yield and easy to
operate as well. The alternated solution from this study is to broaden road
lines of 3,5 meter on each intersection and the alternated road for vehicle to
public transportation in the value of 40%. The result of this analyzed in
existing condition is measured by DS value on Krapyak intersection 1,29;
emission of CO 2089 gram and in Tol Krapyak – Jatingaleh is of 1,41; emission
CO 1903 gram. The broaden of road line (3,5 meter) the value DS Krapyak
intersection 0,73 (decrease 43,3%); emission CO 2293 gram (increase 8,89%) in
Tol Krapyak – Jatingaleh intersection the value DS 0,74 (decrease 47,5%);
emission CO 1899 gram (decrease 0,21%). The assumption of the change of private
to public transportation of 40% the value DS in Krapyak intersection 0,71%
(decrease 44,9%); emission CO 1353 gram (decrease 35,2%) in Tol Krapyak –
Jatingaleh intersection the value DS 0,62% (decrease 56%); emission CO 1120
gram (decrease 41,1%). The result of analysis can be concluded, assumption
transfer of private car to public transportation equal to 40% is solution able
to be optimal of performance service of intersection. Where result of DS equal
to 0,71 and 0,62 which have fulfilled conditions of intersection performance ≤
0,75, and also emission of CO 1,353 ppm and 1,120 ppm have fulfilled conditions
of value float pollution boundary that is, ranging from 0 - 50 ppm where,
entering in good category (there no effect to environment and health). Hence
can be recommended, for related government utilize to repair the pre
requirement and suitable requirement public transportations, and improve
security, service of consumer of public transportation. In research
hereinafter, enabled to use ODM method and program of Synchro 7.0.
