Traffic Density Calculator
Free Traffic Density Calculator is helpful to estimate the traffic on roads. It will find the traffic density, average travel speed, and traffic flow of vehicles in a short span of time. You just have to enter the number of vehicles at a particular time flow, and a number of vehicles on a road of specific length info to know the output.
What is the Traffic Density? | Traffic Density Formula
In simple terms, traffic density is defined as the number of vehicles occupying a unit length of the roadway at a given time. It is an important microscopic parameter of traffic flow used by system operators and users to evaluate traffic performance. Traffic density tells you how significant the congestion of cars on the road is. If the traffic density is high, then the traffic flow reaches zero, which forms a traffic jam.
The traffic density can be calculated with the number of vehicles m that occupy the segment of a road of length L. Traffic Density Formula is here:
Traffic Density = m/L
The inverse of traffic density is the headway which is the distance between the front tip of 2 vehicles driving one after another. The unit to represent traffic density is vehicles/km.
Traffic Flow Definition | Traffic Flow Formula
Traffic flow is the study of the movement of individual vehicles and drivers between two points and the interactions they make with each other. It is defined as the number of vehicles that pass through a point at a given period. We usually measure it by making a note of the vehicle's entry. To convert the number into an hourly rate, we need this equation.
Traffic Flow = n/t
Where n is the number of vehicles that passed by a point during the time period t.
The traffic flow becomes zero in 2 cases when there is no traffic or all the vehicles are stuck in a traffic jam. The unit to represent flow is vehicles/hr.
How to Calculate Average Travel Speed?
Traffic flow and density are interlinked to the average travel speed of a vehicle. These flow, density and travel speed are called the fundamental characteristics of a traffic flow, and the formula is here:
Traffic Flow = Speed * Density
The simple steps to find the travel speed are along the lines:
- Measure how many vehicles through one point in a given time frame.
- Also, count the number of vehicles occupying a segment of a road at once.
- Find the headway between the cars a reciprocal of the density.
- Divide the flow by density to get the travel speed.
FAQs on Traffic Density Calculator
1. How is traffic density defined?
Traffic density is the number of vehicles that occupy the segment of a road length.
2. How is traffic flow calculated?
The traffic flow is calculated by multiplying the travel speed with the density.
3. What is the unit of traffic density?
The traffic density unit is the number of vehicles per kilometre.
4. What is the average travel speed formula?
The average travel speed formula is flow = speed * density.
