PEMINDAHAN U-TURN (PUTARAN BALIK) MENJADI SIMPANG BERSINYAL DI RUAS JALAN VETERAN UTARA KOTA MAKASSAR

North Veteran Street in Makassar, as an arterial road, experiences high traffic volume and a saturated U-turn with a saturation degree of 0.99. This leads to congestion with a V/C ratio of 0.99 and a Level of Service E. This research employs a quantitative method to identify solutions and implement traffic engineering management. The results indicate that the U-turn saturation degree after traffic engineering management decreases to 0.64. A performance comparison before and after traffic engineering management reveals significant improvements across all approaches. On South Veteran Street, the delay reduces from 289.7 seconds to 30.94 seconds, representing a performance improvement of 89.32%. The queue length decreases from 262.23 meters to 118.9 meters, demonstrating a 54.66% performance improvement. On North Veteran Street, the delay decreases from 72.323 seconds to 10.38 seconds, indicating an 85.65% performance improvement. The queue length decreases from 10.89 meters to 7.79 meters, representing a 28.47% performance improvement. On West Monginsidi Street, the delay decreases from 2,272.7 seconds to 160.82 seconds, indicating a 92.92% performance improvement. The queue length decreases from 344.28 meters to 158.73 meters, representing a 53.9% performance improvement. These findings demonstrate the effectiveness of traffic engineering management in improving traffic flow and Level of Service on North Veteran Street.
