Traffic Flow Rate Calculator

Calculate traffic volume, flow rate, density, and speed: q = k·u (Greenshields). Peak hour factor PHF = peak hour volume/4×15-min peak. Design hour volume DHV = AADT×K-factor. Level of service LOS from HCM.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Calculate traffic volume, flow rate, density, and speed: q = k·u (Greenshields). Peak hour factor PHF = peak hour volume/4×15-min peak. Design hour volume DHV = AADT×K-factor. Level of service LOS from HCM

Each component has a specific meaning:

  • HCM — The hcm recorded for the patient or scenario being assessed.

Note: Interpret the traffic flow result against the clinical thresholds and context described above.

How to Use

Enter the HCM for the patient or scenario you are assessing. Calculate traffic volume, flow rate, density, and speed: q = k·u (Greenshields). Peak hour factor PHF = peak hour volume/4×15-min peak. Design hour volume DHV = AADT×K-factor. Level of service LOS from HCM. Use the traffic flow result to inform your clinical assessment.
