1 Grade Separation & Interchange

2 Menurut Banks (2002) pada prinsipnya ada tiga cara untuk memecahkan konflik pergerakan lalulintas pada suatu persimpangan. 1.melalui solusi Time-sharing yang melibatkan pengaturan penggunaan badan jalan untuk masing-masing arah pergerakan lalulintas pada setiap periode waktu tertentu, contoh dari solusi tersebut adalah persimpangan berlampu lalulintas (signalized intersection).

3 2.melalui solusi Space-sharing yang merubah konflik pergerakan bersilangan (crossing) menjadi jalinan (weaving), contoh dari solusi tersebut adalah bundaran lalulintas (roundabout).

4 3.melalui solusi Grade separation yang meniadakan konflik pergerakan bersilangan dengan menempatkan arus lalulintas pada elevasi yang berbeda pada titik konflik, contoh dari solusi tersebut adalah persimpangan tidak sebidang (interchange).

5 Definition A grade-separated intersection is formed when the roadways that meet at the intersection are separated in the vertical plane to eliminate crossing conflicts. Grade Separation If one road is carried over or under another by means of bridge, but without connections between them, the facility is called a Grade Separation

7 Fly Over

8 Interchange Interchange If connecting roadways to permit turning movements in one or more quadrants are provided, it is called an Interchange

9 An interchange is a grade separation with connectors (ramps) to facilitate turning movements. An interchange eliminates collisions at crossing points in the main through lanes.
