Macroscopic Traffic Density Solution

STEP 0: Pre-Calculation Summary

Formula Used

Traffic Density in vpm = Hourly Flow Rate in vph/(Avg. Travel Speed/0.277778)
K_c = Q_i/(V_m/0.277778)
This formula uses 3 Variables

Variables Used

Traffic Density in vpm - Traffic Density in vpm (vehicle per mile), is the average number of vehicles that occupy one mile or one kilometer of road space, expressed in vehicles per mile or per kilometer.
Hourly Flow Rate in vph - Hourly Flow Rate in vph is the number of vehicles moving on a line in a period of one hour.
Avg. Travel Speed - (Measured in Meter per Second) - Avg. Travel Speed is the average of the speed of all the vehicles passing through the lane in one hour.

STEP 1: Convert Input(s) to Base Unit

Hourly Flow Rate in vph: 1000 --> No Conversion Required
Avg. Travel Speed: 30 Kilometer per Hour --> 8.33333333333333 Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_c = Q_i/(V_m/0.277778) --> 1000/(8.33333333333333/0.277778)

Evaluating ... ...

K_c = 33.33336

STEP 3: Convert Result to Output's Unit

33.33336 --> No Conversion Required

FINAL ANSWER

33.33336 <-- Traffic Density in vpm

(Calculation completed in 00.004 seconds)
