Compound annual growth rate (CAGR) is the rate of return that would be required for an investment to grow from its beginning balance to its ending balance, assuming the profits were reinvested at the end of each year of the investment’s lifespan.

What Is Compound Annual Growth Rate – CAGR?
Compound annual growth rate (CAGR) is the rate of return that would be required for an investment to grow from its beginning balance to its ending balance, assuming the profits were reinvested at the end of each year of the investment’s lifespan.
Formula and Calculation of CAGR
To calculate the CAGR of an investment:
Example to Use CAGR
Imagine total increment in traffic is 10,000 with the following manner:
We can see that on an annual basis, the year-to-year growth rates are quite different as shown in the parenthesis.
On the other hand, the compound annual growth rate smooths the investment’s performance and ignores the fact that 2014 and 2016 were so different from 2015. The CAGR over that period was 23.86% and can be calculated as follows:
CAGR=(19,000/10,000)^{frac{1/3}}-1=23.86%
The compound annual growth rate of 23.86% over the three-year period can help to compare alternatives for traffic or make forecasts of future values.
Determine the cumulative compound growth rate (CGR) for the design traffic.
Transportation Engineering I. A highway transportation agency is conducting a traffic count on an existing highway for the purpose of determine the directional design volume. An automatic traffic counter using a weigh-in-motion (WIM) equipment gave a total continuous one-year count of 4,372,096 axles. Manual classification studies at the count station indicated the following: Passenger cars = 3-axle trucks 4-axle trucks 5-axle trucks = 69% 21% 6% 4% (a) Calculate the existing average annual daily traffic (AADT) in vehicles per day....
Design an embedded system using MSP430 to control a traffic light system. It is included a complete design description of a traffic light system to help you in your design. Show the hardware schematics and the software needed to complete your design.
Design an optimization experiment to determine the optimum pH for growth of E. coli that produce GFP.
Q1: The predicted traffic mix of a proposed four-lane urban freeway: Passenger cars = 69% • Single-unit trucks o 2-axle, 5000 lb/axle = 20% o 2-axle, 9000 lb/axle = 5% o 3-axle or more 23,000 lb/axle = 4% Tractor semitrailers and combinations: 3-axle 20,000 lb/axle = 2% The projected AADT during the first year of operation is 3500 (both directions). If the traffic growth rate is estimated at 4% and the design life = 20 years, determine the total equivalent...
4. Explain how the rate of crystal growth can affect the purity of a recrystallized compound.
Design a finite state machine for a traffic light at the intersection of north-south traffic and east-west traffic. The light can be red, green or yellow. Assume a 30 second clock. Assume that the light will change only if a car is coming in the other direction. If cars are in both north-south and east-west, the light will change from one direction to the other. What are the machine states? What are the inputs? What are the outputs? Draw state...
5. In a traffic investigation, the total number of trucks weighed is 117. The detailed axle load information for these 235 trucks is listed in the table below. Please (you can use Excel for calculation): a) What is the average number of axles per truck? (5 point) b) Calculate the truck factor for an asphalt pavement (assume Pt 2.5 and SN-5).(10 point) c) If the initial design year ADT is 4,000, truck percentage is 20%, traffic annual growth rate is...

Could you please answer this question manually without using any software? The traffic on the design lane of a proposed four-lane rural Interstate highway consists of 40% trucks. Studies have shown that the truck factor can be taken as 0.45. Design a suitable flexible pavement using the 1993 AASHTO method if the ADTT during the first year of operation is 1200. PSIni-4.2 and PSIterminal-2.0. The growth rate is 5%, the design life is 20 years, the reliability level is 95%...
