The Ponchatrain Bridge is a 16-mile toll bridge that crosses Lake Ponchatrain in New Orleans. Currently, there are 7 toll booths, each staffed by an employee. Since Hurricane Katrina, the Port Authority has been considering replacing the employees with machines. Many factors must be considered because the employees are unionized. However, one of the Port Authority's concerns is the effect that replacing the employees with machines will have on the times that drivers spend in the system. Customers arrive to any one toll booth at a rate of 12 per minute. In the exact change lanes with employees, the service time is essentially constant at 4 seconds for each driver. With machines, the average service time would still be 4 seconds, but it would be negative exponential rather than constant, because it takes time for the coins to rattle around in the machine.

For the "Exact Change Lane" with employee

The average time driver spends waiting to pay the toll = __ seconds (round your response to two decimal places).

The average time spent by a driver in the toll system (waiting and paying) = __ seconds (round your response to two decimal places)

The average number of drivers waiting in the line to pay the toll at a toll

booth=__ drivers (round your response to two decimal places).

The average number of drivers at any toll booth, namely, in the system = __ drivers (round your response to two decimal places).

For the lane with the proposed machine

The average time driver spends waiting to pay the toll = __ seconds (round your response to two decimal places).

The average time spent by a driver in the toll system (waiting and paying) = __ seconds (round your response to two decimal places).

The average number of drivers waiting in the line to pay the toll at a toll booth= __ drivers (round your response to two decimal places).

The average number of drivers at any toll booth, namely, in the system drivers __ (round your response to two decimal places).

As a result of proposed change, the average time spent per driver waiting in the line to pay the toll increases by __ (round your response to the nearest whole number).

As a result of proposed change, the average time spent per driver in the toll system increases by __ (round your response to the nearest whole number).

As a result of proposed change, the average number of drivers waiting in the line to pay the toll increases by (round your response to the nearest whole number).

As a result of proposed change, the average number of drivers at any toll booth increases by (round your response to the nearest whole number).

A city has built a bridge over a river and it decides to charge
a toll to everyone who crosses. For one year, the city charges a
variety of different tolls and records information on how many
drivers cross the bridge. The city thus gathers information about
elasticity of demand. If the city wishes to raise as much revenue
as possible from the tolls, where will the city decide to charge a
toll: in the inelastic portion of the demand...

New Orleans Shipping. If the share price of Emaline, a New
Orleans-based shipping firm, rises from $12.13 to $15.96 over a
one-year period, calculate the rate of return to the shareholder
given each of the following:
a. The company paid no dividends.
b. The company paid a dividend of $1.01 per share.
c. The company paid the dividend and the total return to the
shareholder is separated into the dividend yield and the capital
gain.

The Delaware River Joint Toll Bridge Commission increased the
tool on the bridges on Route 22 and Interstate 78 from New Jersey
to Pennsylvania from $0.50 to $0.75 in December. In November, the
Route 22 bridge had 519,337 crossings and the Interstate 78 bridge
had 728,002. Suppose that the price elasticity of demand for the
Route 22 bridge was .2696 and that for the Interstate 78 bridge was
1.556. (Assume nothing other than the toll change occurred during
the months...

When crossing the Golden Gate Bridge, traveling into San
Francisco, all drivers must pay a toll. Suppose the amount of time
(in minutes) drivers wait in line to pay the toll follows an
exponential distribution with a probability density function of
f(x) = 0.49e−0.49x.
a. What is the mean waiting time that drivers face when entering
San Francisco via the Golden Gate Bridge? (Round your answer to 2
decimal places.)
b. What is the probability that a driver spends more...

Iron Bridge offers the "Ten-Mile" rummage sale along route 322
to Runnymede on Saturday March 11th. Consumers who go to the sale
will spend $60 each with 200 shoppers per mile in total over the
length of the sale. They will incur an expense of $2 per mile
one-way to travel to get yard goods. Shoppers are evenly
distributed along the route and travel to the nearest booth.
Vendors pay a $300 fee to participate in the sale and forego...

A survey of a sample of 26 hotels in New Orleans found that the
average hotel room rate s $88.42 with a standard deviation of $5.62
and another survey of 25 hotels in the Phoenix area found that the
average room rate is $80.61. Assume with a standard deviation of
$4.83. At α = 0.05, can it be concluded that there is a
significant difference in the rates?

. A prestressed road bridge of span 16 + 0.01 (35× 2) m
consists of a concrete slab of 420 mm thick with parallel
post-tensioned cables, in each of which the force at transfer is
440 kN. If the bridge is required to support a uniformly
distributed applied load of 38 + 0.01 (135) kN/m , with tensile

In 2011, New Orleans, Louisiana experienced an aggressive
recession as compared to the rest of country. With unemployment
rates topping 15%, the city was faced with many challenges
financially, economically, and socially.
In addition to the financial challenges, the city was also
experiencing political instability and corruption. Various major
city officials were being investigated for fraud, bribery, and
other criminal charges.
