2. Why Tom Bradley ?
It's an international terminal. Therefore, it is very busy most of the time, and there are enough passengers to sample for our project.

3. What was measured ….. Loading/Unloading time
Number of cars passing by vs. stopping at departure
Means of transportation (taxi, bus, shuttle, private car)
Reason of trip (vacation vs. business)
Local vs. visiting passengers

4. What we found out…
Taxis do not create traffic. In fact, private cars create the traffic because:
They are lost
Loading/unloading takes longer
Saying good bye to their relatives (hugging, emotions, etc.) which is time consuming
Also, taxis have specific spots to load/unload passengers and luggages

6. Layout of LAX

7. Methodology Surveys with taxi drivers & traffic enforcement officers.
Compared cars passing by and cars stopping.
Measured loading and unloading time.
Survey with passengers to establish what determines decision in their choice of transportation.
Quantitative Measures- Anova, Binomial, F-test, Inference about Pairs of treatment Means.

8. Probabilities of Vehicles to take <1minute to load/unload

9. Probabilities of Vehicles to take 1.1-2 minutes to Load/Unload

10. Probabilities of Vehicles to take >2 minutes to load/unload

11. Probabilities of Vehicles Stopping By

12. Probabilities of Vehicles Passing By

21. Comparison of 50 observations based on three different categories
Passengers (groups) who took a taxi vs. passengers who chose other vehicles
Local passenger (groups) vs. visitors
Business travelers vs. leisure travelers (count of parties)

22. Box plot comparison of 50 observations based on three different categories
Passengers (groups) who took a taxi vs. passengers who other vehicles
Local passenger (groups) vs. visitors
Business travelers vs. leisure travelers (count of parties)

23. Conclusion No conclusion on why travelers chose to take taxi
Failed to find a relationship between
Locals vs. Visitors
Business vs. Leisure
Taxi Cab vs. Other Transportations
Thus, these factors do not matter
Private cars are the most counted to load/unload passengers
Private vehicles take a significantly longer time to load and unload
Traffic congestion in LAX is mainly caused by private cars not taxi cabs

24. Recommendations Increase uniformed personnel/traffic coordinators
Limit the loading and unloading time at curbside to 2 minutes
Strictly enforce traffic regulations
Set up electronic signs
Send out traffic alerts within LAX
Provide alternate location for passengers in tour groups
Provide 15 minutes free parking
