Introduction
Intelligent transport systems (ITS) are transport systems in which advanced information, communication,
sensor and control technologies, including the Internet, are applied to increase safety, sustainability,
efficiency, and comfort.
A distinguishing feature of ‘ITS’ is its communication with outside entities.
Some ITS systems operate autonomously, for example, ‘adaptive cruise control’ uses radar/lidar/ and/or
video to characterize the behaviour of the vehicle in front and adjust its vehicle speed accordingly. Some
ITS systems are informative, for example, ‘Variable Message Signs’ at the roadside, or transmitted into
the vehicle, provide information and advice to the driver. Some ITS systems are semi-autonomous in
that they are largely autonomous but rely on ‘static’ or ‘broadcast’ data, for example, GNSS (2.5) based
‘SatNav’ systems operate autonomously within a vehicle but are dependent on receiving data broadcast
from satellites in order to calculate the location of the vehicle.
Cooperative Intelligent Transport Systems (C-ITS) are a group of ITS technologies where service provision
is enabled by, or enhanced by, the use of ‘live’, present situation related, dynamic data/information from
other entities of similar functionality [for example, from one vehicle to other vehicle(s)], and/or between
different elements of the transport network, including vehicles and infrastructure [for example,
from the vehicle to an infrastructure managed system or from an infrastructure managed system to
vehicle(s)]. Effectively, these systems allow vehicles to ‘talk’ to each other and to the infrastructure.
These systems have significant potential to improve the transport network.
A distinguishing feature of ‘C-ITS’ is that data are used across application/service boundaries.
It will be immediately clear to the reader that such systems present the possibility of driver distraction
(2.4), both through visual overload (display presentation and visual or oral provision of information
and/or via instructions or advice). The purpose of this Technical Report is to identify potential critical
driver distraction and information display issues that C-ITS service provision may introduce, to consider
how to control, limit or mitigate such issues.
Existing rules (2.12) govern the use of technology inside vehicles to reduce driver distraction (2.4). This
Technical Report identifies and discusses how C-ITS applications may fit within these existing rules and
discusses whether they may raise additional risks.
This Technical Report is a ‘living document’ and as our experience with C-ITS develops, it is intended that
it will be updated from time to time, as and when we see opportunities to improve this Technical Report.

TECHNICAL REPORT ISO/TR 17427-10:2015(E)
Intelligent transport systems — Cooperative ITS —
Part 10:
Driver distraction and information display
1 Scope
The scope of this Technical Report is, as an informative document, to identify potential critical driver
distraction (2.4) and information display issues that C-ITS service provision may introduce, to consider
strategies for how to identify, control, limit or mitigate such issues. The objective of this Technical
Report is to raise awareness of and consideration of such issues and to give pointers, where appropriate,
to existing standards deliverables that provide specifications for all or some of these aspects. This
Technical Report does not provide specifications for solutions of these issues.
Existing rules (2.12) govern the use of technology inside vehicles to reduce driver distraction.
NOTE The issues of driver distraction (2.4) and information display affect the design of all aspects of C-ITS
service provision and are a critical factor in C-ITS system design and instantiation. However, while the general
issues that affect C-ITS system design and implementation and related issues of what and how data in a C-ITS
assisted application service provides and is realized and is therefore developed within ISO TC 204/CEN TC 278,
most of the detailed aspects of physical presentation and human factors within the vehicle are standardized
within ISO TC 22.

4.2 Guidance
This Technical Report is designed to provide guidance and a direction for those considering the issues
concerning driver distraction and information display associated with the deployment of C-ITS service
provision. It does not purport to be a list of all potential driver distraction (2.4) and information display
factors which will vary according to the application (2.1) service being provided, the regime of the
jurisdiction (2.10), the location of the instantiation, and to the form of the instantiation, nor does it
provide definitive specification. Rather, this Technical Report discusses and raises awareness of the
major driver distraction and information display issues to be considered and provides guidance and
direction for considering and managing driver distraction and information display in the context of
future and instantiation specific deployments of C-ITS.
4.3 ITS and ‘driver distraction and information display’
Driver distraction (2.4) has become an increasing concern amongst road safety experts, with the
increasing range of technologies within vehicles creating the potential for drivers to have their
attention taken away from the driving task. C-ITS has the potential to create further distractions if not
implemented appropriately.
Distraction (2.4) is when drivers divert their attention away from the driving task to focus on another
[14][1]
activity instead. Distraction can come in several ways:
— visual – eyes off the road (or focusing on the wrong part);
— manual – hands off the wheel;
— cognitive – mind off the road;
— biomechanical – requiring action on the part of the driver.
C-ITS have the potential to increase safety and, for example, collision warning systems will be designed
to only notify a driver by exception (i.e. an alarm would be generated only when a crash was likely and
the driver needed to take evasive action). These alarms should therefore not affect the general driving
task the majority of time. However, designers will need to be careful to ensure that such warning
alarms are sufficiently intuitive that drivers immediately know what to do; poorly designed alarms
could decrease safety if they divert attention from the immediate risk or create confusion.

‘Infotainment’ applications may create more of an on-going distraction (2.4) risk; this is however already
an existing risk with infotainment systems today. C-ITS channels may create new ways for this content
to be shared with a vehicle but it is not expected that this will substantially change the risks involved
associated with ‘infotainment’.
Driver distraction (2.4) and information display is the subject of International Regulation and National
Regulations and recommendations.

d) System behaviour
e) Information about the system
4.3.1.3 ESOP design objectives
— The system supports the driver and does not give rise to potentially hazardous behaviour by the
driver or other road users.
— The allocation of driver attention while interacting with system displays and controls remains
compatible with the attentional demand of the driving situation.
— The system does not distract or visually entertain the driver.
— The system does not present information to the driver which results in potentially hazardous
behaviour by the driver or other road users.
— Interfaces and interface with systems intended to be used in combination by the driver while the
vehicle is in motion are consistent and compatible.
4.3.2 US NHTSA distraction guidelines
Minimize driver distraction (2.4) from electronic devices by encouraging better driver-device interfaces.
Conformance is voluntary.
Guidelines (2.6) implementation in three phases:
— Phase 1 – Visual-manual interfaces for devices installed by vehicle manufacturers (2013);
— Phase 2 – Portable and aftermarket devices (future work);
— Phase 3 – Voice-based auditory interfaces (future work).
4.4 C-ITS driver distraction and overload issues in context
It is important that potential driver distraction (2.4) and display issues created by C-ITS service
provision are not viewed in isolation. C-ITS service provision is simply yet another potential source of
driver distraction of visual or audible overload. Indeed, designed wisely, C-ITS service provision may
often be used to reduce such overloads.
The prime driver distraction (2.4) and visual display issues remain those described and addressed in
4.3. The principle context for C-IS is to ensure that
a) C-ITS service provision does not add to driver distraction/overload, and
b) C-ITS service provision, where possible, uses opportunity to reduce driver distraction/overload

5 What are the key driver distraction and information display issues
5.1 General
Existing rules (2.12) and guidelines (see 4.3) govern the use of technology inside vehicles to reduce
driver distraction (2.4). An assessment is required of how C-ITS applications fit within these existing
rules and whether they raise additional risks. Key findings indicate the following:
— Initial C-ITS applications are likely to require human recognition of the signals and timely and
proportionate responses. This reliance on human factors (see 4.3) could increase risks in certain
circumstances;
— C-ITS, including driver distraction and information display considerations, are not yet explicitly
regulated in most countries;
— Relevant terms such as ‘visual display unit’ and ‘driver’s aid’ are not precisely defined in the ‘Highway
Code/Driving Rules’ of most countries. However, devices providing C-ITS applications would likely
fall under the definition of a ‘driver’s aid’ or similar and be allowable under the road rules;
— In addition to ensuring that C-ITS meets safety objectives, legislation may be required to ensure that
legitimate C-ITS functions are legalized and that drivers using the technology are not caught by laws
prohibiting the use of mobile phones while driving. Any required changes to the law will need to be
addressed by jurisdictions on a national or state basis;
— Guidelines relating to the safety and ergonomic functionality of in-vehicle electronic devices have
been developed to address this issue (see 4.3 and Bibliography).
C-ITS will provide more information to drivers to empower them to make better driving decisions, at
least in its early development when C-ITS is expected to be, at least initially, largely based on advisory
systems that require human recognition of the signals. The challenge for designers is to achieve this
without overloading the driver’s cognitive load. Messages shall be prioritized in order to ensure that the
driver receives critical information at the critical time. Drivers should be able to distinguish a critical
message from a host of other in-vehicle systems (2.7) competing for his or her attention.
Safety is a primary objective of C-ITS but there is a risk that its introduction will inadvertently
compromise safety in certain scenarios. The challenge for manufacturers and C-ITS service providers is
to provide more in-vehicle information or enable more selective prioritized presentation of information
through new systems without unnecessarily distracting, overwhelming or confusing drivers.
The American Automobile Association Foundation for Traffic Safety defines driver distraction (2.4)
as occurring:
“when a driver is delayed in the recognition of information needed to safely accomplish the driving
task because some event, activity, object or person within or outside the vehicle compelled or tended to
induce the driver’s shifting attention away from the driving task.”
It has alternatively been defined as “the diversion of attention away from activities critical for safe
[4]
driving toward a competing activity.”
As stated above, distraction (2.4) can be visual, auditory, biomechanical, physical or cognitive.
Driver distraction (2.4) can be caused by the actio
