Transportation systems
Concepts and definitions
Dr. Lina Shbeeb2
Terms and Definitions
• Transport: is a science that concerns with the efficient
movement of people and goods that is undertaken to
accomplish objectives to complete tasks that require
transfer from one location to another
• Transportation Engineering: is concerned with the
application of scientific principles to the planning, design;
operation & management of transportation systems. It is
a sub-speciality of civil engineering. However, it is
inherently multidisciplinary overlapping diverse fields as
economics; psychology; geography; city planning; public
administration; political science; industrial & electrical
engineering
Dr. Lina Shbeeb3
Transportation Systems
• Physical “fixed” facilities: streets; roads;
highways; railroads; airport; sea & river ports;
pipelines and canals.
• Flow entities: fleets of vehicles; vessels and
aircrafts.
• Control systems refers to the technological ways
in which individual vehicles are guided on fixed
facilities. It can be done manual or automatic.
They include means that permit the efficient safe
and smooth operation of streams of vehicles and
reduce conflicts between vehicles [Signing;
Marking and signalling]
Transportation systems consists of the following components:
Dr. Lina Shbeeb4
• Facility oriented organization are involved in
planning; designing; constructing; maintaining &
operating fixed facilities
• Operation organization “ carriers” concerned
with operating fleets to provide transportation
services [Railroads; airlines; ships; truck lines;
transit operator; private car owner, etc]
• Operating bases and facilities for vehicle
maintenance facilities
Transportation Systems
Dr. Lina Shbeeb5
..Characteristics of transportation
• Highly qualitative and differentiated [By time of
the day; day of the week; journey purpose and
type of cargo)
• It is derived and transport is not an end by itself.
People are travelling in order to satisfy their
needs at their destinations and for the seek of
transport
• It takes place over space [the distribution of
activities over space]. The spatiality of demand
leads to problem of lack of coordination which
affect equilibrium between demand and supply
Transport demand characteristics:
Dr. Lina Shbeeb6
• It is a service and not a good. We cannot stock
it. Transport service must be consumed when
and where it is produced otherwise its benefit is
lost.
• Transport infrastructure is lumpy and take long
time to be carried out.
• Transport investment has an important political
role.
• Transport is very important elements in the
welfare of nations and well being of urban and
rural dweller.

Dr. Lina Shbeeb7
Transportation system classification
• Transportation system is categorized into four major
sub-system according to the medium on which the flow
elements are supported. These subsystem are
commonly referred as modes.
• Modes describe various means of travel.
• The four major subsystem are
The definition of transportation systems makes a distinction between
passengers and freight “goods”. Both are needed to satisfy human needs and
both constitute a significant portion of Gross National Product

Transportation provider type
• Hire system are further classified into
– Contract Carriers: provide service to public
under individual contractual arrangement
– Common Carriers offer scheduled service and
are open to all member of public willing to pay
the posted fare.
• Mass transportation or Mass transit refer
to the common carriage of passengers;
taxi; car rental
Transportation systems are classified as either public or private or classified
as for hire or not for hire
Dr. Lina Shbeeb10
Urban Transportation systems
• The intra-city or urban distribution of freight is
predominantly accomplished by highway subsystem
using vans; trucks.
• The major movement within urban areas are related
to passenger transport.
• Water transport is found within urban areas, it is
related to passenger transport.
• Air transportation is unsuited for urban travel
• Transport means available for urban travel are land
based regardless of being private or public.
• Mode of transport in urban, heavy rail; light rail, bus
Dr. Lina Shbeeb11
Transportation Modes
• Highways are the most dominant mode of
transport in most countries of the world including
Jordan.
• The highway system is used by private vehicles;
truck lines; bus lines.
• Highway systems serves intercity passengers;
freight transportation; urban passenger transport
& distribution of goods.
Dr. Lina Shbeeb12
Major Characteristics of highway systems
• Very high accessibility to almost all potential
destination
• Direct service with very low-to-door travel time
• Moderate line haul speed & capacities
• Capital costs of physical facilities are moderate
• Vehicle used are small & cheep to be owned by
individual compared to all other mode.
• Total investment of physical facilities & vehicle is
high
• Operating cost is high
• Environmental impact of the system as a whole
are high and of major concerns of societies
Dr. Lina Shbeeb13
Urban transit
• It is a specialized mode. It includes traditional
mass transit modes [Buses, street cars, light rail,
rapid rail transit & para-transit]
• Tram “street car”: Vehicles received their power
from overhead power. They are operating on
tracks sharing the roadway with cars and buses
• Light rail: A term embracing a wide range of
electrical powered vehicle running on steel rails
(metro). Passengers board from road surface or
low plat form. It operated along street but maybe
provided with exclusive right of way
Dr. Lina Shbeeb14
….Urban transit
• Rapid rail transit system called metro is the
underground tube operate on exclusive R.O.W
and relatively high speeds & provide highest line
capacity available.
• Para-transit: A term applies to small passenger
vehicles operating informally on fare-paying
basis & serving in some places as an alternative
to regular bus transit services.

Dr. Lina Shbeeb19
Who use urban transit system
• Mainly serves passenger
transportation(10% of passenger trips in
USA is made by transit, the percentage is
much higher in Europe)
• Transit passengers are either persons
making work trips into central business
district, usually referred as
commuters/choice rider or passenger
without access to automobile often
referred to as captive rider
Dr. Lina Shbeeb20
Characteristics of Urban Transit
• Line haul speeds vary a great deal(Bus are slow where
rapid rail transit has quite high speed.
• Door-to-door travel time are greater than those of
automobiles with an exception in CBD.
• Accessibility depend on route & stop station spacing but
in general it is less than of private car.
• Capacities are high.
• Capital costs of rail system are high (both physical
facilities & vehicles)
• Operating costs for both bus and rail system are
moderate but operating costs per trip is almost higher
than dare.
• Environmental impact are regarded as being less than
those of private cars.
Dr. Lina Shbeeb21
Rail Transportation
• The primary market for rail is intercity
freight, considerable amount of general
cargo are shipped by rail; particularly the
bulk cargo.
• Rail share for intercity passenger miles is
relatively low. Most passenger rail trips are
of short to intermediate length are limited
to high density corridor
Dr. Lina Shbeeb22
• Provides Moderate speed & level of
accessibility.
• High & unreliable door-to-door travel times;
however continuous work is under-taken to
reduce the travel time.
• Physical facilities for railway represent heavy
investment.
• Capital cost of locomotives & railcars are
relatively high & productivity is low
• Maintenance costs for track are relatively high
• Operating cost per ton-mile are low
• Environmental impact are comparatively low
Rail Transportation characteristics
Dr. Lina Shbeeb23
Air transportation Characteristics
• High line haul speed
• Accessibility is limited (relatively little importance
because of great length of trips made by air)
• Capacities of individual aircraft are moderate but
productivity is high due to high speed.
• Capital & operating costs are both quite high but
because of high productivity, the cost per passenger
carried is moderate.
• Cost of general aviation airports and aircraft are
moderate.
• Environmental impact are significant especially
• the noise impact of commercial aviation, but are of
much less concern than those of highway system
Include commercial airlines, air freight carriers and general aviation (private
aircraft). Air transportation serves intercity passenger travel (long-distance
travel
Dr. Lina Shbeeb24
Water Transportation
• Transportation by water can be
categorized by
– inland transport
– Ocean transport
• Ocean transport include container ships;
bulk cargo carriers & oil tankers.
• Water transportation serves intercity
freight.
• Inland waterways serve bulk goods
• Ocean shipping carries all types of goods.
Dr. Lina Shbeeb25
• Low speed; low accessibility
• High capacities
• Capital cost of vessel is high but operating
costs per ton-mile are low
• Environmental impact are relatively low,
but if oil spills occur, serious problem rise
Water Transportation characteristics
Dr. Lina Shbeeb26
Pipe lines transportation characteristics
• Low speed to high speed continuous flow
transportation
• Costs are low
• Environment impact is normally quite low
once they are built. However, construction
impact is sometime of concern.
Pipe line transportation is specialized in freight transportation system. It
serves primarily crude oil.
Other modes
Cables & belt system, they do not have significant role.
They are used for specialized passengers “Ski-left and
moving belt in airports
Dr. Lina Shbeeb27
Institutional Structure
• Transportation should be the responsibility of government
body
• The government should be in charge of formulating national
polices & research development for transportation facilities &
services
• Transport service & lines are organized by governmental body
• Transport administration is further organized geographically
into region and district.
• The design, construction, and maintenance of transportation
system is organized by governmental body
• Local government at city level are responsible of setting
standards for design street & roads, maintaining & operating
them & they maybe directly involved in the design &
construction of their facilities.
• Transport planning is responsibility of an agency that exist at
national level or district level or municipality level.
• Private organization involved in transportation sector are the
carriers such as airlines, truck lines, bus operators
Dr. Lina Shbeeb28
System for financing transportation
• User charges include direct charges such as fares, tolls
& indirect sources such as fuel tax.
• General fund revenues collected by different levels of
government are derived from regular taxes “No direct
relationship between source of fund and the activity
which they spent on”
• Private investment occurs in the part of transportation
system that are normally under private control (carrier).
• Cross-subsidization occurs when revenues collected
from users of one type of transportation are used to
finance some other type of system (Gasoline tax
revenue to finance public transport)
Source of funds for transportation are

Lec 01 Introduction of Transportation Engineering (Transportation Engineering Dr.Lina Shbeeb)

  • 1. Dr. Lina Shbeeb1 Transportation Engineering Transportation systems Concepts and definitions
  • 2. Dr. Lina Shbeeb2 Terms and Definitions • Transport: is a science that concerns with the efficient movement of people and goods that is undertaken to accomplish objectives to complete tasks that require transfer from one location to another • Transportation Engineering: is concerned with the application of scientific principles to the planning, design; operation & management of transportation systems. It is a sub-speciality of civil engineering. However, it is inherently multidisciplinary overlapping diverse fields as economics; psychology; geography; city planning; public administration; political science; industrial & electrical engineering
  • 3. Dr. Lina Shbeeb3 Transportation Systems • Physical “fixed” facilities: streets; roads; highways; railroads; airport; sea & river ports; pipelines and canals. • Flow entities: fleets of vehicles; vessels and aircrafts. • Control systems refers to the technological ways in which individual vehicles are guided on fixed facilities. It can be done manual or automatic. They include means that permit the efficient safe and smooth operation of streams of vehicles and reduce conflicts between vehicles [Signing; Marking and signalling] Transportation systems consists of the following components:
  • 4. Dr. Lina Shbeeb4 • Facility oriented organization are involved in planning; designing; constructing; maintaining & operating fixed facilities • Operation organization “ carriers” concerned with operating fleets to provide transportation services [Railroads; airlines; ships; truck lines; transit operator; private car owner, etc] • Operating bases and facilities for vehicle maintenance facilities Transportation Systems
  • 5. Dr. Lina Shbeeb5 ..Characteristics of transportation • Highly qualitative and differentiated [By time of the day; day of the week; journey purpose and type of cargo) • It is derived and transport is not an end by itself. People are travelling in order to satisfy their needs at their destinations and for the seek of transport • It takes place over space [the distribution of activities over space]. The spatiality of demand leads to problem of lack of coordination which affect equilibrium between demand and supply Transport demand characteristics:
  • 6. Dr. Lina Shbeeb6 • It is a service and not a good. We cannot stock it. Transport service must be consumed when and where it is produced otherwise its benefit is lost. • Transport infrastructure is lumpy and take long time to be carried out. • Transport investment has an important political role. • Transport is very important elements in the welfare of nations and well being of urban and rural dweller. ….Characteristics of transportation Transport supply characteristics:
  • 7. Dr. Lina Shbeeb7 Transportation system classification • Transportation system is categorized into four major sub-system according to the medium on which the flow elements are supported. These subsystem are commonly referred as modes. • Modes describe various means of travel. • The four major subsystem are The definition of transportation systems makes a distinction between passengers and freight “goods”. Both are needed to satisfy human needs and both constitute a significant portion of Gross National Product PipelinesWater Transportation Air Transportation Land Transportation OilInlandDomesticHighway Gas; otherOceanInternationalRail
  • 8. Dr. Lina Shbeeb8 Mode classification by geography location PassengersFreightLocation Private Auto-Highway Truck-HighwayUrban Transit-Highway/Railway Private Auto-HighwayTruck-Highway Intercity BusRailway RailOcean shipping AirInland water Pipelines Air Conveyor beltSpecial Purpose Cable system
  • 9. Dr. Lina Shbeeb9 Transportation provider type • Hire system are further classified into – Contract Carriers: provide service to public under individual contractual arrangement – Common Carriers offer scheduled service and are open to all member of public willing to pay the posted fare. • Mass transportation or Mass transit refer to the common carriage of passengers; taxi; car rental Transportation systems are classified as either public or private or classified as for hire or not for hire
  • 10. Dr. Lina Shbeeb10 Urban Transportation systems • The intra-city or urban distribution of freight is predominantly accomplished by highway subsystem using vans; trucks. • The major movement within urban areas are related to passenger transport. • Water transport is found within urban areas, it is related to passenger transport. • Air transportation is unsuited for urban travel • Transport means available for urban travel are land based regardless of being private or public. • Mode of transport in urban, heavy rail; light rail, bus
  • 11. Dr. Lina Shbeeb11 Transportation Modes • Highways are the most dominant mode of transport in most countries of the world including Jordan. • The highway system is used by private vehicles; truck lines; bus lines. • Highway systems serves intercity passengers; freight transportation; urban passenger transport & distribution of goods.
  • 12. Dr. Lina Shbeeb12 Major Characteristics of highway systems • Very high accessibility to almost all potential destination • Direct service with very low-to-door travel time • Moderate line haul speed & capacities • Capital costs of physical facilities are moderate • Vehicle used are small & cheep to be owned by individual compared to all other mode. • Total investment of physical facilities & vehicle is high • Operating cost is high • Environmental impact of the system as a whole are high and of major concerns of societies
  • 13. Dr. Lina Shbeeb13 Urban transit • It is a specialized mode. It includes traditional mass transit modes [Buses, street cars, light rail, rapid rail transit & para-transit] • Tram “street car”: Vehicles received their power from overhead power. They are operating on tracks sharing the roadway with cars and buses • Light rail: A term embracing a wide range of electrical powered vehicle running on steel rails (metro). Passengers board from road surface or low plat form. It operated along street but maybe provided with exclusive right of way
  • 14. Dr. Lina Shbeeb14 ….Urban transit • Rapid rail transit system called metro is the underground tube operate on exclusive R.O.W and relatively high speeds & provide highest line capacity available. • Para-transit: A term applies to small passenger vehicles operating informally on fare-paying basis & serving in some places as an alternative to regular bus transit services.
  • 17. Dr. Lina Shbeeb17 Rapid Rail transit
  • 19. Dr. Lina Shbeeb19 Who use urban transit system • Mainly serves passenger transportation(10% of passenger trips in USA is made by transit, the percentage is much higher in Europe) • Transit passengers are either persons making work trips into central business district, usually referred as commuters/choice rider or passenger without access to automobile often referred to as captive rider
  • 20. Dr. Lina Shbeeb20 Characteristics of Urban Transit • Line haul speeds vary a great deal(Bus are slow where rapid rail transit has quite high speed. • Door-to-door travel time are greater than those of automobiles with an exception in CBD. • Accessibility depend on route & stop station spacing but in general it is less than of private car. • Capacities are high. • Capital costs of rail system are high (both physical facilities & vehicles) • Operating costs for both bus and rail system are moderate but operating costs per trip is almost higher than dare. • Environmental impact are regarded as being less than those of private cars.
  • 21. Dr. Lina Shbeeb21 Rail Transportation • The primary market for rail is intercity freight, considerable amount of general cargo are shipped by rail; particularly the bulk cargo. • Rail share for intercity passenger miles is relatively low. Most passenger rail trips are of short to intermediate length are limited to high density corridor
  • 22. Dr. Lina Shbeeb22 • Provides Moderate speed & level of accessibility. • High & unreliable door-to-door travel times; however continuous work is under-taken to reduce the travel time. • Physical facilities for railway represent heavy investment. • Capital cost of locomotives & railcars are relatively high & productivity is low • Maintenance costs for track are relatively high • Operating cost per ton-mile are low • Environmental impact are comparatively low Rail Transportation characteristics
  • 23. Dr. Lina Shbeeb23 Air transportation Characteristics • High line haul speed • Accessibility is limited (relatively little importance because of great length of trips made by air) • Capacities of individual aircraft are moderate but productivity is high due to high speed. • Capital & operating costs are both quite high but because of high productivity, the cost per passenger carried is moderate. • Cost of general aviation airports and aircraft are moderate. • Environmental impact are significant especially • the noise impact of commercial aviation, but are of much less concern than those of highway system Include commercial airlines, air freight carriers and general aviation (private aircraft). Air transportation serves intercity passenger travel (long-distance travel
  • 24. Dr. Lina Shbeeb24 Water Transportation • Transportation by water can be categorized by – inland transport – Ocean transport • Ocean transport include container ships; bulk cargo carriers & oil tankers. • Water transportation serves intercity freight. • Inland waterways serve bulk goods • Ocean shipping carries all types of goods.
  • 25. Dr. Lina Shbeeb25 • Low speed; low accessibility • High capacities • Capital cost of vessel is high but operating costs per ton-mile are low • Environmental impact are relatively low, but if oil spills occur, serious problem rise Water Transportation characteristics
  • 26. Dr. Lina Shbeeb26 Pipe lines transportation characteristics • Low speed to high speed continuous flow transportation • Costs are low • Environment impact is normally quite low once they are built. However, construction impact is sometime of concern. Pipe line transportation is specialized in freight transportation system. It serves primarily crude oil. Other modes Cables & belt system, they do not have significant role. They are used for specialized passengers “Ski-left and moving belt in airports
  • 27. Dr. Lina Shbeeb27 Institutional Structure • Transportation should be the responsibility of government body • The government should be in charge of formulating national polices & research development for transportation facilities & services • Transport service & lines are organized by governmental body • Transport administration is further organized geographically into region and district. • The design, construction, and maintenance of transportation system is organized by governmental body • Local government at city level are responsible of setting standards for design street & roads, maintaining & operating them & they maybe directly involved in the design & construction of their facilities. • Transport planning is responsibility of an agency that exist at national level or district level or municipality level. • Private organization involved in transportation sector are the carriers such as airlines, truck lines, bus operators
  • 28. Dr. Lina Shbeeb28 System for financing transportation • User charges include direct charges such as fares, tolls & indirect sources such as fuel tax. • General fund revenues collected by different levels of government are derived from regular taxes “No direct relationship between source of fund and the activity which they spent on” • Private investment occurs in the part of transportation system that are normally under private control (carrier). • Cross-subsidization occurs when revenues collected from users of one type of transportation are used to finance some other type of system (Gasoline tax revenue to finance public transport) Source of funds for transportation are
