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.

4.1 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
