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
