5 Transportation Engineering: Definition..the application of the principles of engineering, planning, analysis, and design to facilitate the movement of people and goods. A transportation engineer must be concerned with: 1. The design and maintenance of physical infrastructure 2. Efficiency, safety, environmental impacts, and energy usage in the movement of people and goods (Fricker and Whitford, 2014) Transportation can be multimodal. A single trip can involve multiple modes 2014 Boise State University 5

6 Transportation Engineer: Responsibilities 1. Not confined to the movement of people only; concerns the movement of goods as well 2. Not concerned with designing of facilities only. Need to work with Public Industry Elected officials Employees of government agencies 2014 Boise State University 6

21 Impressive statistics 47,000 miles of highway 55,000 bridges, 14,800 interchanges 1.8 million acres of right of way 100,000 workers to build it 2014 Boise State University 21

22 Interstate Trivia Which Interstate Highway goes through the most states? I 95 (15 states) Which is the shortest Interstate highway? 2 digit: I-97 (17.62 miles; Entirely within Maryland) 3 digit: I-878 (0.70 miles; New York; Part of NY State Route 878) Which is the longest Interstate? I-90 ( miles; Boston, MA to Seattle, WA) 2014 Boise State University 22

23 Interstate Trivia (2) Interstates highways through Idaho I 15 (196 miles) I 84 (276 miles) I 86 (63 miles; located completely within Idaho) I 90 (74 miles) I 184 (3.62 miles) 2014 Boise State University 23

24 Interstate MythBusters Interstates were constructed as a way of evacuating cities during a nuclear war No. President Eisenhower s support for the Interstate System was primarily based on civilian needs support for economic development, improved highway safety, congestion relief. Of course the military value of such a system was added bonus One in five files of the Interstate System is straight so airplanes can land in case of emergencies No. The designers had no such intention The only built objects astronauts can see from space is the Interstate System No. The astronauts (from an altitude of about 155 miles) can see many objects like roads, cities, dams, airports, etc. if they know where to look 2014 Boise State University 24

26 Highway system classification Federal highways (nation-wide freeway facilities) State primary and secondary systems (state-wide arterial routes) Local and county roads City streets Transportation modes 2014 Boise State University 26

27 Passenger transportation Transportation Modes auto: short trips, selected end points, low cost? air: long trips, intercity travels mass transit (light rail, commuter rail): short trips, cheap rail (AMTRAK): intercity travel. Freight shipments truck: point to point delivery, reliable air: fast, costly, limited-capacity. waterway: cheap, slow rail: bulk movements, cheap, slow, inflexible pipeline: for gas and oil, inflexible 2014 Boise State University 27

28 Transportation Modes Airport system classification Commercial Service (CS) >2,500 enplanements Primary Airports >10,000 enplanements. Defined as hubs, based on the percentage of the total annual U.S. enplanements: Large Hubs (29): >1% Medium Hubs (37): % Small Hubs (72): % Non-Hubs (244): < 0.049% Non-Primary Commercial Service Airports: 2,500-10,000 annual enplanements. Cargo Service Airports cargo with a total landed weight of more than 100 million pounds. Reliever Airports General Aviation (GA) 2014 Boise State University 28
