Question

reduce traffic congestion in downtown Wynberg, Indiana, the mayor convinces the city to set up a public

transportation system. Bus-only lanes are to be established, and commuters will be encouraged to “park and

ride”; that is, to park their cars in suburban parking lots and then take buses from there to work and back at

a cost of one dollar per ride. Each bus is to have a fare machine that accepts only dollar bills. Passengers

insert a bill into the slot as they enter the bus. Sensors inside the fare machine scan the bill, and the software

in the machine uses an image recognition algorithm to decide whether the passenger has indeed inserted a

valid dollar bill into the slot. It is important that the fare machine be accurate because, once the news gets

out that any piece of paper will do the trick, fare income will plummet to effectively zero. Conversely, if

the machine regularly rejects valid dollar bills, passengers will be reluctant to use the buses. In addition,

the fare machine must be rapid. Passengers will be equally reluctant to use the buses if the machine spends

15 seconds coming to a decision regarding the validity of a dollar bill—it would take even a relatively small

number of passengers many minutes to board a bus. Therefore, the requirements for the fare machine

software include an average response time of less than 1 second and an average accuracy of at least 98 percent​
