Mayjend Sutoyo S. and Zafri Zam-Zam Streets are situated in the central part of the city of
Banjarmasin, with traffic having a high rate of growth. This occurs because the area constitutes one of the
primary routes to the centers of the economy, education, and health; offices; and banks, and provide access to
and from Trisakti Port. On the Mayjend Sutoyo S. streets, there is a signaledt-junction where jams commonly
form, which is the signaled t-junction on the Mayjend Sutoyo S. Streets–Jalan Zafri Zam-Zam Streets. This
results from heavy traffic and heavy vehicles (trucks, trailers, and so on) that slow down the traffic on the
Mayjend Sutoyo S. Streets.This research carried out an analysis based on the Indonesian Highway Capacity
Manual,1997, under the condition that the t-junction was managed using several alternatives.Research findings
suggest that performance of the signaled t-junction under the existing condition is the lowest as it has a delay
value (30.46 s/pcu) or, which means that, the LOS of the t-junction obtains a grade D. The improvement to make
in order to get the best LOS is Alternative 4, which is to improve the cycle time, forbid heavy vehicles, and add
lanes where those who intend to turn left can turn left directly with a delay value of 18.05 s/pcu and the LOS
getting a grade C.
