Transportation System Today

TERMINAL

Function:
Place the beginning and end of transport operations
Venue change modes or routes
Facilities maintenance services and transportation means (vehicles & equipment)
Storage, distribution, and loading and unloading goods

Terminal Type:
Port
Airfield
Train Station
Bus Terminal
Container terminal
Pump station
etc.


CHARACTERISTICS:
1. Service Time
The smaller the better.
Example:
- Ships = 15% of the time (for winter maintenance)
- The plane flew = 30 - 60 minutes every 2 hours of flying (25-50%)
2. Facilities Provided
Depending on the type of traffic, for example:
- Transportation of goods: vegetables and foods need to place the cooling; liquid ingredients necessary pipes and pumps; bulk mining commodities need to belt motion; containers need cranes.
- Transport of passengers need lifts, toilets, canteen, break rooms, etc..
3. Inspection and Distribution Process
So smoothly, the current arrangements need to be efficient and be broken.
Example: the arrival and departure flow separation, separation place for an introduction and the examination of documents, classification purposes.
 PROBLEMS
1. Need for Integrated Plan
Cases often occur: first character of the local terminal planning & new expanded when needed.
2. Cost
Cost depends on mileage segment, the further the unit costs of increasingly expensive.
Cost depends on volume and number of terminal transportation.
Covers: the cost of unloading, warehouse rental costs, etc..
3. Land Use and Local Conditions
Terminal ideally as close as possible to the source of power trip.
Terminal face parallel to the road, performing at the crossings and congestion.

4. Environmental Impact
Terminal lead pollution: air, water, noise, and visual (waste gas, dust, noise and engine vibration)
Steps to reduce pollution: install anti-noise devices, etc..
 SAMPLE TERMINAL
1. Land Transportation Terminal
Includes: bus, train, or multi-modal.
2. Water Transport Terminals
Port: a sheltered waters, where ships could dock and load or unload goods safely.
Type of port:
Type of water (natural, semi-natural, artificial)
Purpose (military, fisheries, commerce, recreation)
Location (sea, lake, river)
Auxiliary port facilities:
breaking waves (breakwater), fastening the ship (jetti), anchoring the collision (fenders), cranes, railways, oil pipelines, etc..
3. Air Transport Terminal
The layout depends on:
- Configuration runway
single, parallel, intersecting, and non-intersecting, affect the capacity of aircraft operation.
- Flight operations control system
based on the vision / use instruments
Terminal region includes: the terminal building, aircraft parking area (apron), and aircraft hangars.
Facilities: visitor and passenger waiting rooms, passenger processing space, control tower, etc..

Size apron hanging:
- Size and number of gate position (loading area)
- Aircraft parking configurations (nose in, angled nose in, nose out, angled nose out, parallel)
- Parking system (frontal, open apron, finger system, satellite).
Aircraft parking configuration:
- Nose in & angled nose in.
advantage: the front door of the aircraft near the terminal building and the blast of heat from jet engines do not get into the building
losses: the back door with a remote terminal
- Nose out & angled nose out
reverse
Parking system:
- Frontal: simple and economical, limited to a small terminal.
- Satellite: suitable for a lot of aircraft, the cost of expensive.
4. Other Terminal
Examples: pump stations, terminals belt motion.

TRANSPORTATION SYSTEM OPERATIONS
Definition: Everything that relates to how to use or utilize the transportation system in fulfilling its functions and to serve existing demand.
Scope
Network utilization
Determination of the route, schedule, and frequency
Provision of capacity
How to make payment
Criteria to measure performance (level and quality of service)
Characteristics of Transport Services: Services of transport services can not be stored for use at another time.
 ROUTE DETERMINATION
Determining Basis
1. Service System
2 things that underlie the classification:
types of routes and travel (short distance, intermediate, or distant)
kind of operation / type stops (stop, skip-stop, express)
2. Concept Hierarchy Service
The need to develop transport systems in accordance with regional developments and the needs of the population movement.
Hierarchy of service (on the transport system already complete), aims to further optimize the function of each subsystem or modes.
The principle of hierarchy of service: a smaller transport into the feeder (feeder) to the larger transportation system.
Example:
In the urban public transport system:
Public transportation (low capacity) to serve short-range transport and serve the area whose needs are not too large (the edge of town)
Buses serve the transportation is quite far, but the need is not so great
Train (highest capacity) to serve transportation needs in the region is very high.
Route Type
The route is commonly used: radial, circumferensial / loop, tangential.
The length and location of the route:

Request
The location of the origin destination (O-D)
Availability of land
The cost of providing

 SCHEDULE & FREQUENCY DETERMINATION
Determining Basis
Depends on:

Existing demand
The nature of services performed
Type of operation time (day, only during rush hour, or on special events)
Control system of transportation systems

Schedule Type
Schedule and frequency:
Same all the time-
-Distinguished (with no busy rush hour, weekdays and holidays, etc.)
 PAYMENT DETERMINATION
Determining Basis
The principle of payment:

-Uniform (much closer together)
-Based on the distance
Based on the time-
Based on passenger-type

On systems that differentiate the tariff, the tariff is determined by:
Furthermore, the distance traveled, more expensive
-The more often people use the transport at any given time, more and more cheap
Payment Method
- Immediately before boarding the vehicle (manual or automatic)
- Subscriptions
The tariff should consider:
- The purpose of the provision of transport (the social aspect or profit-making)
- Large income users
- The existence of competition from other systems
 PERFORMANCE CRITERIA
Parameters / indicators to measure the level of success or performance of the operating system:
1. The level of service, involving quantitative measures.
2. Quality of service, involves a qualitative measure.
 Service Level Factor
1. Capacity
: Number of passengers / goods that can be moved in units of time (person / hour or tons / hour).
For example:
- Passenger capacity in public transport: 4-8 orang/m2
- Ideal capacity road: 1000 - 1200 pcu / lane / hour
- Runway capacity: 25-50 operations per hour
Some ways to increase capacity:
enlarge the size, speed up the movement, tamp passenger / goods.
Restrictions should be noted:
space limitations, safety, comfort, etc..
2. Accessibility
Stating the ease of using a particular transport.
Transportation system should be easily accessible from various places and at all times.
 Service Quality Factors
1. Safety
Associated with control systems used.
2. Reliability
Related to factors such as time schedules and guarantee accuracy reached their destination.
3. Flexibility
Ease of change is in all things as a result of events that changed not in accordance with the planned scenario.
4. Comfort
Associated with the layout of seats, air conditioning system in a vehicle, the existence of special facilities (toilets, dining, operating times, etc)
5. Speed
A very important factor and is associated with problems of transportation system efficiency.
6. Impact
Environmental impacts (pollution, noise, vibration) to the socio-political impact.

a process that not only improve transportation planning and traffic engineering of traditional, but also focuses on the establishment of a mobility, security, energy conservation, and protection of environmental quality through the application of scientific methods based on the principles of engineering and planning system.
Or:
Transportation System Management is a process that involves planning and operation of a unitary system of urban transportation.
 GOAL
Coordinate all travel through the operation of equipment, regulatory, and policy services, so as to achieve an efficiency and productivity of the transport system.
 GOAL
Conservation funding sources, energy, environmental quality and quality of urban life.

 IMPLEMENTATION MODES

Traffic restrictions (traffic restriction)
Traffic Control (traffic restraints)
Fiscal system / financial (fiscal measures)
Incentives (incentives system)
Improved transit service
Provision of facilities for cyclists and pedestrians
Provision / development of paratransit service
Traffic Management (traffic management

 Traffic Restrictions
Prevent vehicle traffic, to not enter, stop or cross the route / area.
Only targeted at certain categories of vehicles.
Example:
Closing the road is permanently or temporarily to all vehicle traffic
The implementation of the road pembuntuan
Prohibition of use of roads based on area or time
Restricted parking on the street or the elimination of parking on the street
 Traffic Control
Controlling vehicle traffic by applying a consequence for the use of transportation systems.
Giving users the option of transport to use the system with certain consequences or completely avoid its use.
Example:
 Distribution center area into several zones, with the application of one-way street system, and regulation of certain turns, that does not allow travel between the zones or traffic basis.
 Implementation of road pricing, by charging fees to users of the route / area of the solid.
Implementation:
toll road
application of screen-line pricing (charging fees on vehicles passing through the imaginary line that crosses all the existing corridor)
implementation of cordon pricing (charging fees on vehicles passing through the imaginary line around an area to be solid)
application of area licensing (a fee on vehicles entering into certain areas of solid)
 Implementation of parking control (parking control), to limit the total number of vehicles parking in the central area of activity, and to limit the volume of traffic in the city as a whole.
Implementation:
limit the number of parking lots and parking locations
restrictions on duration of use of parking
withdrawal cost of parking by varying levels based on time usage
parking restrictions only to certain road users
 System Fiscal / Financial
Associated with the application of tax to things that are directly related to transportation.
Example:
Application of vehicle purchase tax
Vehicle registration tax
Import tax kendaraan
Purchases of fuel tax
 Incentive System
Transport users will get the added benefit directly as a result of the implementation of the system.
Example:
 setting working hours in turns and the implementation of flexible work schedules, which will reduce the volume of traffic at rush hour.
 Implementation of policy on the operation of public transport.
Implementation:
 travel expenses that the amount varies according to financial ability of users
 implementation of a flat fare (cost is much closer together)
 the use of subscription cards with unlimited term
 free of charge for use of public transport
 Improved Transit Service
Because of the high cost of design and procurement of new types of transportation modes, the wisdom that is taken is still using conventional public transportation modes but with:
 Special Treatment
ie: giving priority to buses at intersections, the application of a special lane for buses, the implementation of opposing lane exclusively for buses.
 Provision of facilities for the convenience of users
eg: provision of facilities within the public transportation (air conditioning, telephone, newspapers & magazines, toilet), the provision of bus stops with completeness, the procurement of transit terminals, provision of facilities 'park & ride'
 Improved transport kapasaitas, using high capacity buses
 Provision of facilities for bicycle riders and Pedestrian
Provision of facilities for pedestrians (such as a special lane for pedestrians and pedestrian malls) will increase the flow and safety of pedestrians.
Special lane for bicycles will make no disruption to traffic wear bicycle, so that will improve safety for riders.

 Provision / Development Paratransit Service
Paratransit is like transit because the service is offered to the public, while the equation with a private vehicle because its operation is based on demand (do not have fixed routes and schedules)
Implementation:
 Implementation: car-pooling, van-pooling
 provision: taxi, dial-a-ride buses, bajaj, bemo, rickshaws, shared-ride taxis.
 Traffic Management
To improve traffic conditions and improve the efficiency of road section, so as to avoid the need for road expansion.
Implementation:
 traffic control, by the application of signal coordination, pavement marking, traffic control lights and perlampuan roads, will increase the security and the smooth movement of traffic on road networks.
 Setup traffic flow, to increase road capacity, especially during busy periods, without widening the road. Example: setting one-way street, the application path to change direction, the rules in turn, and specialism route to certain types of modes.
 Development of a minor on the road system, by canalization, widening the road and intersection design.
