How To Benefit From Braess’s Paradox?

Published on February 17, 2022 by Hemanth

How To Benefit From Braess's Paradox? A road network that connects START to END. There are two paths available: one through junction A, and another through junction B. Time taken for traversing START-A = 110 minutes. Time taken to traverse A-END = T/10, where T is the number of cars on the route. Time taken for START-B = T/10, where T is the number of cars on the route. Time taken for B-END = 110 minutes.
Braess’s paradox originates from the observation that overall traffic efficiency in a road network decreases after one or more roads are added to the network.

Why earning more leads to lesser satisfaction: An illustration of the Weber–Fechner laws - On each side, the lower square contains 10 more dots than the upper square. Yet, the perception is different between the left and the right square sets. On the left, 10 dots are in the top square and 20 in the bottom one. The difference is clearly visible. On the right, the top square has 110 dots and the bottom one has 120 dots. The difference is not clearly visible.
