Assume you are observing traffic in a single lane of a highway at a specific location. You measure the average headway and average spacing of passing vehicles as 3.2 seconds and 165 ft, respectively. Calculate the flow, average speed, and density of the traffic stream in this lane?

Traffic flow = 1125 veh/hr

Average speed = 35.15 mi/hr

Traffic density = 32 veh/mi

Explanation:

Given Data:

average headway= h =3.2 sec

average spacing = s = 165 ft

Required:

Traffic flow, average speed and density of traffic

Solution:

a. Traffic flow

It cn be calculated through relation

b. Average Traffic Speed

It can be calculated by the equation

c. Traffic Density

It can be calculated by

oil flow is a highly convective flow compared to water flow at normal temperature and pressure.
