Abstract

Hasil penelitian simpang tiga bersinyal Straat A Kota Kupang yang dilakukan oleh Frans (2014), menyimpulkan bahwa kondisi kinerja simpang berada pada tingkat pelayanan F. Untuk mengatasi masalah tersebut maka pada penelitian ini dilakukan rekayasa lalu lintas berupa penerapan sistem lalu lintas satu arah pada simpul simpang tiga Straat A tersebut, yang meliputi ruas jalan A.Yani, Jalan Flores, dan Jalan Sumba. Pengolahan dan analisa data menggunakan MKJI 1997. Hasil penelitian menunjukkan kinerja Simpang Tiga Straat A dengan penerapan sistem lalu lintas satu arah dikategorikan dalam tingkat pelayanan B yaitu arus stabil, kepadatan rendah, pengemudi masih punya cukup kebebasan memilih kecepatan. Kinerja lalulintas pada ruas jalan yang dipengaruhi adalah ruas jalan A. Yani dengan volume kendaraan maksimum jam puncak 1.646 smp/jam, hambatan samping tergolong sedang, kecepatan aktual 48 km/jam, derajat kejenuhan 0,48 dan tingkat pelayanan C; Pada ruas jalan Sumba, volume kendaraan maksimum jam puncak 1.509 smp/jam, hambatan samping sedang, kecepatan aktual 50 km/jam, derajat kejenuhan 0,48 dan tingkat pelayanan C; Ruas Jalan Flores, volume kendaraan maksimum jam puncaknya adalah 1.342,9 smp/jam, hambatan samping sedang, kecepatan aktual 44 km/jam, derajat kejenuhan 0,48 serta tingkat pelayanan C. Sehingga dapat disimpulkan bahwa penerapan sistem lalu lintas satu arah pada simpang tiga Straat A layak dilakukan. Based on the previous research on the three-legged signalized intersections on Straat A in Kupang City (Frans, 2014), the result showed that the performance was at F level of service. To overcome this problem, this research was conducted by apply the traffic engineering that is the one-way traffic system on the Straat A intersection that covers A. Yani, Flores and Sumba Roads. Data processing and analysis were done using the Indonesian Highway Capacity Manual (MKJI, 1997). The result showed that the performance of Straat A intersection with the implementation of one-way traffic system is categorized at Level of Service (LoS) B that is has steady traffic flow, low traffic density, and the driver still has enough freedom to choose the speed. The traffic performance of the roads that were affected by one way traffic system are as follow: 1. On A. Yani road, the maximum peak hour volume is 1.646 pcu/hour, the side friction is classified medium, the actual speed is 48 kph, the degree of saturation is 0.48 and LoS is at C level; 2. On Sumba road, the maximum peak hour volume is 1509 pcu/hour, the side friction is classified medium, the actual speed is 50 kph, the degree of saturation is 0.48, and LoS level is at grade C; 3. On Flores Road, the maximum peak hour volume is 1.342,9 pcu/hour, the side friction is also classified medium, the actual speed is 44 kph, the degree of saturation is 0.48 and the LoS level is at grade C too.
