May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.Chapter 1 The Profession of Transportation 1-1 To illustr ate the importance of transportation in our national life, identify a transportation-related article that appears in a local or national newspaper. Discuss the issue involved and explain why the article is newsworthy.In 2012, many areas in New York City were devastated by Hurricane Sandy. An article was published on December 2, 2012 in The New York Times to illustrate the importance of transportation on society, especially facing an emergency. Transit officials said that normal train services to the Rockaways were not going to resume for several months. People still needed to go to places, especially in a city like New York, where car ownership is relatively low and many people depend on transit. The article describes the solution found for the transit agency to reduce the impacts of Hurricane Sandy in daily activities of the population of the Rockaways; a special line, the shuttle line H, started running through a stretch of the devastated area, making stops at a limited number of stations.This is an example of an article in a major newspaper that mainly keeps the population informed of their options for transportation after an emergency. In this case, this article also was important to show population in general a sign of progress after a tragedy; the article shows the effort of the transit agency to keep society’s daily activities as normal as possible after the hurricane.1-2 Arrange an interview with a transportation professional in your city or state (that is, someone working for a consulting firm, city, county or state transportation department, transit or rail agency). Inquire about the job he or she performs, why he or she entered the profession and what he or she sees as the future challenges in the field.

Note: This is a brief transcript of an interview with a transportation
professional.
1-3 Keep a diary of all trips you make for a period of three to five days. Record the purpose of the trip, how you traveled, the approximate distance traveled and the trip time. What conclusions can you draw from the data?
The table shown on the next page provides a list of all trips made by a student during a five-day period. The following conclusions can be reached about the student’s travel behavior.
24 trips were made (an average of 4.8 trips per day) 8 trips by bus 9 trips by car 7 trips by walking
248 minutes were spent traveling (an average of 49.6 minutes per day) 77 minutes of travel by bus (31% of total travel time) 90 minutes of travel by car (36% of total travel time) 81 minutes of travel by walking (33% of total travel time)
About an equal amount of time was spent riding buses, walking, and driving a car.
