ALINYEMEN VERTIKAL

Jenis lengkung vertikal dilihat dari letak titik perpotongan kedua bagian lurus (tangen) adalah:
1.      Lengkung vertikal cekung, adalah lengkung di mana titik perpotongan antara    kedua tangen berada di bawah permukaan jalan.
2.      Lengkung vertikal cembung, adalah lengkung di mana titik perpotongan antara kedua tangen berada di atas permukaan jalan yang bersangkutan.
