Length of Railways in Operation refers to the total length of the trunk line for passenger and
freight transportation (including both full operation and temporary operation).
The calculation is based on the actual length of the first line if this line
has a full or partial double (or more). Not included are double tracks, station
sidings, tracks under the charge of stations, branch lines, special-purpose
lines and non-payable connecting lines. The length of railways in operation is
an important indicator to show the
development of the infrastructure of railway transport. It is also
essential data to calculate volume of passenger freight transport, traffic
density and utilization efficiency of locomotives and carriages.
Length of Automatic-blocking and
Semi-automatic-blocking Railways Blocking is a spacing technique by which
a section of the railway only allows one train to pass at a time with the aim
of ensuring traffic safety. Length of automatic-blocking and
semi-automatic-blocking railways refers to length of railways installed with
equipment to perform automatic or manual blocking of trains.
Length of Highways refers to the length of highways which
are built in conformity with the grades specified by the highway engineering
standard [Highways WTBZ-Technical Standard JTJ01-88] formulated by the Ministry
of Transport, and have been formally checked and accepted by the departments of highways and put into use. The length
of highways includes that of the suburb highways at large and
medium-sized cities, highways passing through streets at small cities and
towns, and also the length of bridges and ferry piers. It does not include the
length of streets in big and medium-sized cities and highways built for the
production purpose at factories, mines, forest areas and agricultural areas. If
two or more highways go the same section of the way, the length of the section
is only calculated for once and no duplication is allowed. The length of
highways is an indicator to show the development of the scale of highway
construction and to provide essential information to calculate the transport
network density.
Length of Civil Aviation Routes refers to the length of all routes for civil aviation flights, which
is used to account the freight, during the period of statistics.. There are
usually two ways to calculate the route length: duplicated calculation and
non-duplicated calculateion, the former is the sum of
length of all civil aviation routes, and the latter should deduct the
duplication length of same route among all routes.
Length of Oil (Gas) Pipelines is used as an indicator to show the development, scale and level
of the pipeline transportation. It refers to the actual transport distance of
oil (or gas) products, and is in general calculated according to the length of
single pipeline. If the length of the double pipelines and alternate pipeline
are included, it is called the extension length of the oil (gas) pipelines,
which indicates the actual length of the pipelines built. The commonly used
indicator, the “length of “oil (gas)” pipelines, does
not include the double pipelines. It can reflect the extent and level of
development of pipeline transport.
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.
Freight Ton-kilometres (Passenger-kilometres) 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-kilometres. The formula
is as follows:
Average Static Load of Freight Cars refers to the average cargo weight as loaded by each freight car
under the static condition at the departure station. It is used to show the
utilization extent of the loading capacity of the freight cars. The formula is:
The static load of freight
cars is determined by the nature and type of goods loaded the type of vehicles,
and the technique of loading. Comparison of the average marked load with the
static load of freight cars provides indication on the degree of utilization of
loading capacity of freight cars. For its calculation the following formula is
applied:
Average Daily Haul of Freight Locomotives refers to the average total ton-kilometres
accomplished by each freight transport locomotive over one day and night during
a given period of time. It includes both the weight of the goods carried and
the dead weight of the train itself. It is a comprehensive indicator reflecting
the locomotive efficiency in terms of both time and the pulling force.
Possession of Civil Motor Vehicles
refer to the total numbers of vehicles that are registered and received
vehicles license tags according to the Work Standard for Motor Vehicles
Registration formulated by the Transport Management Office under the department
of public security at the end of the reference period. They are divided into
categories. According to the structure of motor vehicles, they are divided into
passenger vehicles, trucks and others; according to ownership into private
vehicles and vehicles for the unit’s use; according to kind of usage into
working vehicles and non-working vehicles; and according to size of vehicles
into large passenger vehicles, medium-sized passenger vehicles, small passenger
vehicles and mini passenger vehicles, heavy trucks, light-heavy trucks, light trucks
and mini-trucks.
Business Volume of Post and Telecommunications refers to the total amount of postal and telecommunication services,
expressed in value terms, provided by the post and telecommunications departments
for society. This indicator reflects the overall results of development of
postal and telecommunication services. It can be classificated
as postal services and and telecommunication
services. Business volume of post and telecommunications is the sum of all
services in kind multiplying with the unit price (constant price) to get the
total business value.
Mobile Telephone Subscribers refer to persons who have gone through registration procedures in
the operation points of enterprises engaged in telecommunications and are hence
connected with the mobile telephone communication network through the mobile
telephone switchboards and occupy mobile phone numbers. Included are GSM
digital mobile phone subscribers, CDMA digital mobile phone subscribers and
subscribers to intelligent phone cards with roaming facility issued by
telecommunications enterprises and which have been subscribed to and activated
at the end of the reference period.
Internet Users refer to the number of Chinese citizens aged 6 and over who use the
Internet at least for one hour each week.
Local Telephone Subscribers refer to all subscribers who have gone through registration
procedures in the operation points of enterprises engaged in telecommunications
and are hence connected to the local telecommunications service provider
through fixed line network. Included are general subscribers, public telephones
subscribers, N-ISDN subscribers and intelligent network terminal subscribers.
They are also classified in terms of administrative districts as urban
telephone subscribers and rural telephone subscribers according to location.
Household Telephone Subscribers refer to telephone sets installed in the dwelling units of urban or
rural residents, and registered as residence subscribers for payment, including
three types of payment for the service: private payment, public payment and
free service in accordance with relevant regulations.
Capacity of Long Distance Telephone Exchanges refers to the rated capacity of telephone exchanges to connect long
distance telephone network, including capacity of international telephone
exchanges.
Capacity of Office Telephone Exchanges refers to the capacity (measured in gate) of telephone exchanges
installed in the offices of telecommunication service providers for
communication between fixed telephones. It includes the capacity of both manual
and automatic exchanges in use and for stand-by purpose. The capacity of
subscriber exchanges is not included.
