Transpo Flashcards
Transportation Engineering
Application of technology and scientific principles to the planning, functional design, operation and management on facilities for any mode of transportation in order to provide for the safe, rapid, comfortable, convenient, economical and environmentally compatible movement of people and goods.
Traffic Engineering
Branch of transportation engineering which deals with planning, geometric design and traffic operations of roads, street and highways, their networks, terminals, abutting lands and relationship with other modes of transportation.
– Physical Facilities\n– Fleets\n– operating bases and facilities\n– organizations\n– operating strategies\n
Components of Transportation System
Physical Civil Engineering
Civil engineering activity related to the provision of physical facilities, includes the design, construction and maintenance of fixed transportation facilities
Systems Engineering
Civil engineering activity related to planning and operation of transportation system, involves transportation planning, including the analysis of system capacity; design of traffic control and operation strategies
Objective: Knit together the inhabitants of a territory\nConstraints: human environment
Transportation System Objective and Constraints
Multi–modal
Two or more modes are combined to provide utility and service to the public
Exotic
Modes that are not yet being used commercially but which have been tested in a pilot project
Quasi–Transport
Facsimile transmission of documents by wire and radio
Highways\nUrban transit\nAir\nRail\nWater\nPipelines\nOther modes
Modes of transportation
System
Set of interrelated parts which perform a number of function in order to achieve common goal
Components
Parts of a system
System Analysis
The application of the scientific method to the solution of complex problems.
Goals
Desired end states
Objectives
Operational statements of goals
MOE
Measures of Effectiveness
MOE
Measurement of the degree to which each alternative action satisfies the objective
Measures of Costs
Measures of benefits forgone or the opportunities lost for each of the alternatives
Standard
Fixed objective
Policy
Guiding principle or course of action adopted to forward progress toward an objective
Transportation Planner and Engineer
Recognize the fact that transportation system constitute a potent force in shaping the course of regional development
Complementary\nTransferability\nCompetition
Three conditions for movement and transportation
Trip
An event
Travel
Process
Land use
One of the prime determinant of movement and activity
Trip generation
Activity that will dictate what transportation facilities such as streets and bus systems will be needed to move traffic
Mobility\nUse of resources\nRisk\nOther socio–economic outputs
Outputs of the operating system
Links\nVehicle\nTerminals\nManagement and labor
Four basic elements of transportation system
Locomotion\nActivities\nFeelings\nManipulation\nHealth and safety\nSocial interaction\nMotivation\nLearning\nPerception
Categories of human behavior affected by transportation
Spatial organization\nCirculation and movement\nCommunication\nAmbience\nVisual properties\nResources\nSymbolic properties\nArchitectonic properties\nConsequation\nProtection\nTiming
Properties of physical environment that have direct impact on human behavior
Ubiquity\nMobility\nEfficiency
Three basic attributes of transportation system
Ubiquity
Amount of accessibility to the system, directness of routing between access points, and the system’s flexibility to handle variety of traffic conditions
Mobility
The quantity of travel that can be handled. The capacity of the system to handle traffic and speed are two variables connected with mobility
Efficiency
Relationship between the cost of transportation and productivity of system. Direct costs of a system are composed of a capital and operating cost, while indirect costs comprise adverse impacts and unquantifiable costs, such as safety.
