Vehicle Miles Traveled

Overview

Engineering reference data for Vehicle Miles Traveled in electrical engineering.

Key Formulas

Ohm's Law

$V = IR$

Voltage = Current × Resistance.

Power

$P = VI = I^2R = V^2/R$

Electrical power.

Energy

$E = Pt$

Energy = Power × Time.

Variables

Fundamental Relationships

The core relationships between speed, distance, and time are essential for calculating vehicle miles traveled (VMT) and are governed by the following equations:

Core Kinematic Equations

1. Distance Traveled (given constant speed): $D = V \times t$ Where D is distance, V is velocity (speed), and t is time.

2. Time of Travel (given constant speed): $t = \frac{D}{V}$

3. Speed or Velocity (given distance and time): $V = \frac{D}{t}$

These formulas assume constant velocity over the time period. In real-world traffic or trip analysis, average speed is often used.

Key Unit Conversions

When working with mixed systems (e.g., miles and kilometers, hours and minutes), conversions are critical:

• Speed (Miles per Hour to Kilometers per Hour): $V_{\text{km/h}} = V_{\text{mph}} \times 1.60934$
• Time (Minutes to Decimal Hours): $t_{\text{hours}} = \frac{t_{\text{minutes}}}{60}$
