| Traffic Engineering | Is a branch of transportation engineering which deals with planning, geometric design, construction and traffic operations of streets and highways , their networks, terminals, abutting lands in relation with other modes of transportation. |
| Highway Engineering | is a subset of transportation engineering which is a component of civil engineering which is a component operation and maintenance of roads, bridges, and tunnels to ensure safe, effective transportation of people and good. |
| Competition | Is an intervening opportunity to competition among several locations to satisfy demand and supply |
| Physical Engineering | Is a civil engineering activity related to the provision of physical facilities, includes the design, construction and maintenance of fixed transportation facilities. |
| Travel | is a process |
| Policy | Is a guiding principle or course of action adopted to forward progress toward an objective. |
| Superelevation | Or banking of curves to counteract the centripedal/centrifugal acceleration produced as a vehicle rounds a curve. |
| Overhaul Distance | Is transpoting of earthwork far or more than the designated distance. |
| Intersection | Is a place where 2 or more vehicles intersect at the same grade or level. |
| Fill | It is considered negative; embankment, earthwork, below the constructed soil. |
| Transportation Engineering | Is the application of technological, scientific principles to the planning, functional design, operation, construction and management facilities for any mode of transportation in order to provide the safe, rapid, comfortable, convenient, economical, and environmentally compatible movement of people and goods. |
| Transferability | Is the desire to overcome distance; measured in terms of time and money needed to overcome this distance and the best technology available to achieve it. |
| Trip | Is an event |
| Pipelines | It provide very low speed, high capacity, continuous flow transportation and involve a large amount of working storage. |
| Standard | Is a fixed objective, the lowest and highest level of performance acceptable. |
| Prehaul Distance | Is a transporting of earthwork within the designated distance free of charge. |
| Interchange | Is a junction of two or more highways by a system of separate levels that permit traffic to pass from one to another w/o crossing traffic streams. |
| Cut | Is considered positive; excavation; earthwork above the constructed section. |
| Mass Diagram | It is a graph of cumulative volume of earthwork versus distance in stations from beginning of the job. |
| System Engineering | Civil engineering activity related to planning and operation of transportation demand; analysis of system capacity; design traffic control and operating strategies. |
| Highway | dominant transportation mode used by private vehicles, trucklines and bus lines. |
| Urban Transit | Buses, streetcars, mass transit, light rail, rapid rail transit. |
| Air | commercial airlines, airfreight carriers and general aviation. |
| Rail | Private and public railroads |
| Water | Coastwise Ocean shipping and barge lines. |
| System analysis | Is the application of the scientific method to the solution of complex problems. |
| Goals | are desired end state. |
| Objectives | are operational statement of goals, these should be measurable and attainable; it suggests appropriate measures of effectiveness. |
| Measure of Effectiveness | Is a measurement of the degree to which each alternative of action satisfies the objectives. |
| Standard | Is a fixed objective, the lowest or highest level of performance acceptable. |
| Measure of Cost | measure of benefits forgone or the opportunities lost for each of the alternatives. |
| Complementary | The relative attractiveness between two or more destinations. |
| Land Use | is one of the prime determinants of movement and activity. |
| Trip Generation | is an activity that will dictate what transportation facilities such as streets and bus systems will be needed to move traffic. |
| Categories of Human behavior that are affected by the transportation: | - Locomotion - Activities - Feelings - Manipulation - Health and Safety |
| Transportation system can be evaluated in three basic attributes | - Mobility - Ubiquity - Efficiency |
| Types of people that are generally underserved | - Poor - Elderly - Physically handicap |
| Types of Interchanges | - Partial Cloverleaf, - Directional - Trumpet |
| Mode of transportation of continuous flow system | - Pipelines - Cable - Belt systems |
| Basic Elements of a physical plant in a transportation system | - Links - Vehicles - Terminal |
| Physical Environment that has direct impact on human behavior: | - Ambience - Communication - Protection - Visual Properties - Resources |
| Mode of transportation on water: | - Ships - Hovercraft |
