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
electrotechnical standardization.

Introduction
Energy savings is a priority issue for all cities. ISO 37154, and especially ISO 37161, has addressed how,
where and in what situations energy consumed in transportation services can be saved.
Rail services are indispensable as one of the most efficient means to convey people, delivery items and
freight within cities, between cities and in a large city zone. Rail services are comprised of many service
and technical aspects. To save energy in rail services, there are many options to review for improving
energy efficiency. Energy savings by slowing the speed of the train and still achieving minimum service
schedules is a method that is frequently employed. This method of operation is applicable to other
transportation services or modes that are based on scheduling. Energy saving by modifying speed
profiles offers great energy savings when widely applied to all transportation services.
The principle of this method is rather simple. All trains, buses, trucks and ferries typically run on a
service line or sailing route at the maximum speed technically allowed. Reducing the running speed
will reduce the energy consumption. Commonly, all transportation modes, passengers and freight,
are scheduled to include standing-by time to provide passengers and freight shippers with convenient
service schedules, providing good connections and avoiding odd time for pickup and delivery. Service
schedules can be designated so that when passing another service at a station with more tracks or lanes
on a single-track line or traffic road, or at a wider point on a narrow sailing route, a train, bus, truck or
ferry should come to the station or point by the time designated. If the designated arriving time is set
later than the expected arrival time at a maximum speed, the train or other transportation mode can
run slower. Overall, this will lead to a reduction in the amount of energy to be consumed.
Slow running avoids high acceleration and deceleration, compared to when running at a higher speed.
Passenger-friendly driving will additionally be realized when operating in this energy saving method.
From an environmental standpoint, slow running will contribute to a reduction in carbon monoxide
emission, hydrocarbons, nitrogen oxides, sulphur oxides, lead and aromatic compounds, if services by
engine-driven vehicles.
This document describes how to save energy in scheduled transportation services by modifying speed
profiles.
In the development of this document, ISO Guide 82 has been taken into account in addressing
sustainability issues.

4 Principle of energy saving in transportation operation by modifying speed
profiles of running vehicles and applicable city issues
4.1 General
In smart transportation as designated in this document, energy consumption can be reduced by
modifying the operating speed of transportation service vehicles. That is, by operating the vehicles as
slow as the service schedule permits. All transportation dispatch is managed by operating trains, buses,
trucks and ferries by adhering to service schedules that include leeway or buffer time generated for
customer-friendly transportation services and due to operational reasons. This means that it will take a
longer time going from origin to destination, even if vehicles can arrive earlier by running at maximu
