Transportation Systems Definition and Scope –A transportation system may be defined as consisting of the fixed facilities, the flow entities, and the control system that permit people and goods to overcome the friction of geographical space efficiently in order to participate in timely manner in some desired activity.

Transportation Systems Fixed Facilities: –The physical components Links (e.g., roadway segments, railroad track, and pipes) Nodes (e.g., intersections, interchanges, transit terminals and airport) Flow Entities: –The units that traverse the fixed facilities Vehicles, container units, railroad cars and so on Control System: –Vehicular control and flow control Vehicular control: manual (drivers) or automatic (machine) Flow control: various types of signing, marking, and signal system, and the underlying rules of operations

Transportation Systems Transportation Demand: –Fulfill certain needs, such as going to school, to work, to shop, or to visit with friends –Meet the requirement of work schedule, activity schedule or travel plans Quantification versus Valuation: –Quantify the transportation proposals using the best available models, techniques, and/or tools –Evaluate the quantified results based on value systems

Transportation System Classification Classification Schemes: –Land transportation (a. Highway and b. Rail) –Air transportation (a. Domestic and b. International) –Water transportation (a. Inland, b. Coastal and c. Ocean) –Pipelines transportation (a. Oil, b. Gas and c, Other) Private and Public Transportation: –Private transportation –Public transportation Contract carriers – under individual contract (e.g., taxis, car rentals, and certain individually arranged services) Common carriers – generally scheduled services (e.g., transit bus, mass transportation or mass transit)

Governmental Participation: –Consisting of the rules of conduct, the collective decision-making processes, and the means of enforcing the rules that attempt to impact social and economic order and to maintain the cohesiveness of a society –The U.S. governmental structure places a high value on individual freedom and civil rights Instruments of Governmental Involvement: –Promotion, Regulation and Investment Arguments for and Against Government Intervention The role of Government

Background: –Basic tools necessary for work in the filed of engineering –More concerned with application of scientific knowledge Mathematical Models: –A model may be defined as the representation of a part of reality –A mathematical model employs one or more equations to represent a system and its behavior Components of Mathematical Models –Model postulation, model calibration, and model validation Transportation Models: –Models of physical systems, human factor models, and travel behavior models Tools and Applications
