ANALISIS KINERJA SIMPANG TAK BERSINYAL BERDASARKAN PKJI 2014

(STUDI KASUS SIMPANG TIGA PABRIK GULA JATIBARANG)

Abstrak

Abstrak: Jatibarang merupakan salah satu pusat perekonomian, pendidikan dan pemerintahan di kabupaten Brebes. Kehadiran pusat perekonomian, pendidikan dan pemerintahan dapat meningkatkan volume lalu lintas yang menyebabkan gangguan pada kinerja simpang. Salah satu simpang yang terdampak yaitu Simpang Tiga Tak Bersinyal Pabrik Gula Jatibarang. Berdasarkan keadaan tersebut maka perlu dilakukan analisis kinerja simpang tak bersinyal berdasarkan PKJI 2014 yang bertujuan untuk mengetahui karakteristik dan kinerja simpang.

Abstract: Jatibarang is one of the economic, educational and government centers in Brebes district.
