| dc.description.abstract | Unsignalized T-Intersection BALITTRA at Kebun Karet Street in
Banjarbaru City had a long traffic queue. The queue length from
observations was estimated to be around 15 meters. This research aimed
to know about the performance (degree of saturation, queue length, and
level of service) of Kebun Karet T-Intersection in the existing condition
and finding the alternative solution. This research used MKJI 1997
method to analyze the existing condition and VISSIM modelling software
to find the alternative solution. In the existing condition, degree of
saturation of Kebun Karet T-Intersection was 1,06. The queue length
based on observation for the west was 9,03 m, east was 10,77 and south
was 17,3 m. T-Intersection delay time was 22,23 second with level of
service C. Alternative solution offered was widening the major lane and
adding signalized program to Kebun Karet T-Intersection with the cycle
time adjustment to 91 second based on MKJI 1997 recommendation cycle
time for 3 phase signalized intersection. After modelling the alternative
solution, the degree of saturation on the west was 0,82, east 0,81 and
south was 0,82. The queue length based on VISSIM modelling for the west
was 60,27 m, east was 36,12 and south was 30,60 m. T-Intersection delay
time was 26,19 second with level of service D based on delay T-
intersection time. | en_US |
