Pengaruh Pintu Keluar Mall Bumi Kedaton dan U Turn Sebelum Lintas Jalan Rel di Jalan Sulta Agung (Studi Kasus Simpang Jl. Teuku Umar – Jl. ZA. Pagar Alam – Jl. Sultan Agung)

Abstract

This research used primary data and secondary data. The primary data is obtained from the direct
survey result in the form of geometry data, environmental condition data, traffic flow, signal
timing, and long queues. Secondary data consists of the population in Bandar Lampungat 2012
that is get from BPS Lampung Province. Data analysis is used the Indonesian Manual Highway
Capacity in 1997 for Signalized Intersections. Based on calculations, it can found that the
intersection level of service at aftrenoon peak hour was F with a delay amount 61,50sec/pcu, level
of service at evening peak hour was F with a delay amount 88, 20sec/pcu, and level of service at
night peak hour was F with a delay amount 60, 29sec/pcu. Similarly, with the U Turn result can
obtained the intersection level of service at afternoon peak hour was B, level of service at evening
peak hour was B, and level of service at night peak hour was A.It indicates that the performance of
intersectionis not optimal. To increase the performance of the intersection, need make a changes
in the pattern of setting time control become the pattern of not setting time control based on the
peak condition by changing the cycle time, green time, and inter green time. And the
recommendation needed for the handling of openings U Turn on Jl. Sultan Agung.
