ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International

Standards adopted by the technical committees are circulated to the member bodies for voting.

Publication as an International Standard requires approval by at least 75 % of the member bodies

In exceptional circumstances, when a technical committee has collected data of a different kind from

that which is normally published as an International Standard (“state of the art”, for example), it may

decide by a simple majority vote of its participating members to publish a Technical Report. A Technical

Report is entirely informative in nature and does not have to be reviewed until the data it provides are

utilizing personalized data with respect to trip distance, trip schedule, personal eco mileages,

vehicles information to be utilized to users as a mobility service, which includes electric passenger

vehicles, public transport with bus and/or metro, shared mobility with car sharing, ride sharing,

transportation management services to be provided to users as a variety of service apps on mobile

devices by national authorities, local municipalities and/or private companies for eco-mobility

Conceptual aspects of the general process for four step transportation planning and modelling are

Trip generation as the first stage of the classical transportation demand planning and modelling is the

analysis and model building phase in the conventional transportation planning process. It is a general

term used in the transportation planning process to cover the number of trip ends in given areas. Trip

generation is classified in production and attraction. Production from a origin means number of trips

end originated in a zone, i.e. zone-i. Attraction to a destination means number of trips end attracted to

The decision to travel for a given purpose is called trip generation. The decision to choose a destination

from a origin is directional distribution of trips forms the second stage of travel demand modelling

in the transportation planning process. Trip distribution is determined by the number of trips end

originated in zone-i to number of trips end attracted to zone-j, which can be understood by the matrix

The third stage in travel demand modelling is modal split, which is determined by number of trips

of people process by the different mode of travel. Modal split of travel demand modelling is used to

distribute the total travel demand in two or more mode categories including public transport riders and

personal and/or private vehicle riders. The demand can be split into different modes with respect to

the socio-economic demand variables used to explain mode choice behaviour including income, vehicle

ownership, household size, residence location etc. The supply variables are in vehicle time, waiting

Trip assignment is the fourth and the final phase of the four-step transportation planning process.

Travelers will choose the route which will take minimum travel time, minimum travel distance

The urban mobility applications provide individual users with mobility information services according

to user preference on demand recognized by nomadic via personal O-D trip data, which come up with

network O-D matrix databases. The use cases for urban mobility applications are categorized as trip

generation, network assignment, mode assignment, and information & analysis based on a similar

pattern of conventional four step transportation planning and modelling process, including trip

This standard defines urban mobility use cases and data interface with specifications so that central

and/or local mobility service providers are able to plan and operate mobility integration managements

based on their conventional transportation planning process. Examples include the delivery and

management of ITS services using big data collected by personal nomadic devices in the transportation

networks, as well as the use of smartphone apps for public transit modes and routes planning by traffic

— Urban mobility information integrated with a variety of mobile apps on nomadic devices by multiple

— Mode choice data based on time-effective, cost-effective, and eco-effective manners in the trip

The main purposes for adopting this standard are modelling the urban mobility service platform with

the defined use cases utilizing limited resources of transport means or modes more effectively within

a city transport network. The transport modes defined directly in this standard include bus, shuttle of

1 to 4 seater or of 6 to 12 seater, and service vehicles under ride hailing, car sharing, ride sharing, etc.

The urban mobility application services will include the following group of use cases:

— Trip generation: to collect trip demand or parcel delivery request generated by nomadic devices,

— Network assignment: to monitor the origin and destination (O-D) of user or parcel, and assign the

— Mode assignment: to monitor modes (e.g. bus, shuttle) availability and assign route to the available

— Information and analysis: to guide trip information of the users or parcels and analyse and evaluate
