Explanatory Notes on Main Statistical Indicators
Freight (Passenger) Traffic
refers to the volume of freight (passenger) transported with
various means within a specific period of time. This indicator reflects the
service of the transport industry towards the national economy and people's
living conditions, as well as an important indicator used in formulating and
monitoring transport production plans and research into the scale and pace of
transport development. Freight transport is calculated in tons and passenger
traffic is calculated in terms of number of persons. Freight transport is
calculated in terms of the actual weight of the goods and takes no account of
the type of freight and distance of travel. Passenger traffic is calculated by
the principle that one person can be counted only once in one trip and takes no
account of the travelling distance and ticket price.
The passengers who travel with a half price ticket or a child's ticket is also
calculated as one person.
Turnover Volume of Freight (Passenger)
Traffic
refers to the sum of the product of the volume of
transported cargo (passengers) multiplied by the transport distance. It is an
important indicator to reflect the achievement of the transportation industry.
This is an important indicator to show the total results of the transport
industry; to prepare and examine the transport plan; and to serve as the main
basic data for calculating the efficiency, labour
productivity and unit cost of transport. Normally, the shortest distance
between the departure station and the destination station (i.e., the payable
distance) is the basis in calculating the freight ton-kilometers. The formula
is as followed:
Turnover Volume of Freight
(Passenger) Traffic =��(Freight (Passenger) Traffic ��
Distance of Transportation)
Freight Handled in Ports
refers to the volume of cargo passing in and out the harbor
area and having been loaded and unloaded. The volume of freight handled may be
classified as in-port & out-port. It can also be classified as national
trade and international trade by the attribute of trade or be classified by the
classification of cargo according to the standard of traffic in use The
Classification and Code of Transported Cargo.
Container Handled in Ports
refers to number and weight of containers which are loaded
or unloaded within port area via water carriage. It is often calculated by
entering and leaving port, respectively. TEU was the abbreviation of twenty
foot equivalent unit, which refers to converted number of all kinds of
containers. The conversion method is based on respective conversion ratio and
the number of all kinds of container is converted to the standard number of
20-foot equivalent unit. The conversion ratio is 40-foot container 1:2, 35-foot
container 1:1.75, 20-foot container 1:1, 10-foot
container 1:0.5.
Business Value of Post and
Telecommunication Services
refers to the total amount of post and telecommunication
services, expressed in value terms, provided by the post and telecommunications
departments for the society. Post and telecommunication services can be
classified as letters, parcels, remittance, issue of newspapers and magazines,
fast mail service, express mail service, savings deposits, stamps for
collection, public and individual telegraph service, facsimiles, long-distance
telephone service, leasing of telephone lines, urban paging service, mobile
telephone service, data transfer and transmission, etc. The accounting approach
is to multiply the service products of all types with their average unit price
(constant price) to get sum of business value, plus income from other services
such as leasing of telephone lines and equipment, maintenance of telephone
switchboards and lines on behalf of customers. This indicator reflects the
overall results of post and telecommunications service during a given period,
and is important to study the composition of business service and the
development of post and telecommunications service. The formula is as followed:
Business Value of Post and
Telecommunication Services =
��
(Transaction of Post and Telecommunication Services ��Constant
Price) + Income from leasing, Maintenance and Other Services = Business Volume
of Post + Business Volume of Telecommunication
Civil Motor Vehicles Owned
refers to the total number of vehicles that are registered
and received vehicles license tags according to the Work Standard for Motor
Vehicles Registration formulated by transport management office under
department of public security at the end of reference period. They are divided
into following categories according to the structure of motor vehicles:
passenger vehicles, trucks and others; and private vehicles and vehicles for
units use according to ownerships; working vehicles, non-working vehicles and
special motor vehicles according to kind of usage; large passenger vehicles,
medium passenger vehicles, small passenger vehicles and mini passenger vehicle,
heavy trucks, light-heavy trucks, light trucks and mini trucks according to
sizes of vehicles.
Capacity of Office Telephone
Exchanges
refers to the capacity of telephone exchanges installed in
the local offices of telecommunication service providers for communication
between fixed telephones. It is includes the capacity of both manual and
automatic exchanges in use and for stand-by purpose and calculated according to
the multiplied capacity if equipped with multiplier equipment.
Capacity of
refers to the capacity of the maximum services provided to
subscribers at one time basing on a certain model and transacting capacity of
the mobile telephone exchanges.
