Step-by- Step Calculation Procedures

Ini adalah awal dari apa yang disebut speeded and speeded paremeters sHAN as lateral faktio and superelevation.

Step 1: Deterrel Design Speed

Selet yang sesuai dengan nama cepat based on traffic volume, roadid type, and envirentul conditions.

Step 2: Obtais Laterul Fristion and Superelevation

Itify the memaksimalkan laterul friction coesicient and the of superelevation (anching of the roadway). Theese values are typically provided in standardn or gor goor.

Step 3: Apply the Radius Formula

The basic formula for kalkulating the minimum radius (R) is:

FLT: 0 = V = 1; FLT: 1; FLT: 2: FLT: 2: 2 PD3; 2 (g (e + f))))))) 41; FLT: 3 1f 33; Syariet; 2:

Dimana:

  • V = ejaan (m / s)
  • g = acceleration due to gravy (9.81 m / s £1; FLT: 0 Aver3; 2 Gl1; FLT: 1; ASA3;)
  • e = superelevation (ratio)
  • f = laterul friction coexicent
