Our Expert structures

• Technical Committees• Constituted for the full four years

• « Task Forces »:• Are allowed more flexibility; 2-year activity cycles; cover new topics

and analyze their future relevance for roads; reasonably small groups

• « Special Projects »:• Outsourced by the SG; development of high-level, short documents

that are not within the near-term capacity of the Technical Committeesor Task Forces to complete

• « Regional Task Forces »:• Address topics of particular interest to certain regions, especially those

with many developing countries

2016-2019 Themes

PIARC is addressing the topic of Human Factors in Road Design and Operation

since 2007

Period 2007 – 2011 Committee on «Safer Road Infrastructures» chaired by Joachim VOLLPRACHT (Germany)

Period 2011 – 2015 Committee on «Design and Operation of Safer Road Infrasdtructures» chaired by Mike GREENHALGH (United Kingdom)

Lorenzo Domenichini

NCHRP Rpt 600A scientific discipline that tries to enhance the relationship between devices and systems and the people who are meant to use them through the application of extensive, well-documented, and fully appropriate behavioral data that describe and analyze the capabilities and limitations of human beings.

HUMAN FACTORSDefinitions (1 of 3)

HSMThe interdisciplinary study of human factors applies knowledge from the human sciences such as psychology, physiology, and kinesiology to the design of systems, tasks, and environments for effective and safe use. The goal of understanding the effects of human factors is to reduce the probability and consequences of human error, especially the injuries and fatalities resulting from those errors, by designing systems with respect to human characteristics and limitations.

Lorenzo Domenichini

PIARC DictionaryAbilities and limitations that refer to physical, cognitive and psychological processes, dealing with people's perception, information processing, motivation, decision-making and action.

PIARC RSMHuman Factors are a well-established scientific endeavor that has influenced developments in many areas of technologies. Its application to road safety issues in a formal sense goes back to at least to 1930s (e.g. Forbes, 1939).Contemporary understanding of issues, such as the time it takes to make decisions, the amount of light needed to resolve details and the rate at which information is absorbed underpins key standards in road design …. Since knowledge in human factors continue to evolve, many of its findings remain to be absorbed in technical standards and guidelines

Lorenzo Domenichini

PIARC HF Guide Lines

The term Human Factor refers to the stable natural psychological and physiological threshold limits that contribute to operational mistakes in vehicle handling. The term HF does not include human behaviors or performances.It has nothing to do with personality traits like aggressiveness, the will to violate traffic rules consciously, mistakes because of drugs assumption or ageing.It is a professional term coined around 1930 by the industrial safety engineers to address the general and stable subconscious reactions of common system users and excludes temporary individual conditions.

Lorenzo Domenichini

Sourrounding

PERSONALITY FACTORSexhaustion, heart disease, drugs,

will to violate laws, aggression enforcement / education

CAR DESIGN FACTORS:operating elements, indicating instruments, user friendly car design

Picture: S. Birth

Lorenzo Domenichini

PIARC TC C2 APPROACH TO HUMAN FACTORS

is somewhat different from the others’ approaches.It refers to a MMI (Man Machine Interface) problem:

Man : the DriverMachine : the Road which moves in front of the standing driver

(like in a driving simulator) according to the driver’s decisions

The driver’s decisions (mainly driving speed and vehicle trajectory) are the results of the driver’s perception of the road environment dynamically changing in front of his eyes

Lorenzo Domenichini

Is driving a conscious or an automated process?

Source: 1500 technically unexplainable accidents, Germany (2000-2012)

• To which percentage road user’s behaviour is controlled• by conscious control of acting and decision making?

by infrastructural features?

• Solution: Conscious control 15%Infrastructure 70%Weather or car conditions 15%

if you look at human factors related road deficiencies

Point of interest of the post-accident, damage-oriented, approach(Judiciary system, Insurances)(analysis of the damages and consequences of the crash)

What has this to deal with road safety?

Lorenzo Domenichini

n. 3 Human Factors related Safety RulesI. Provide enough ANTICIPATION TIME

Give enough time to perceive and adapt to changes. Proper anticipation + decision + reaction needs at minimum4 - 6 sec --> (bikers 20m - 35m, pedestrians 6m – 9m, cars -100m, 50km/h).

II. Control drivers FIELD-OF-VIEW(the field of view enables appropriate speed + lane tracking)Offer sufficient amount of bright/colour contrasts and avoid monotonyEnsure reliable optical guidance and orientation. Avoid optical illusions

III. Pre-programme drivers’ behaviourDesign roads with consistent road characteristics in a logical sequence.Offer short distances and minimal effort for VRU. Respect habits, automated/subconscious behavioural patterns

OPTICAL GUIDANCE

SPATIAL PERCEPTION

DRIVERS’ EXPECTATIONS

Lorenzo Domenichini

Few examples to illustrate the meaning of the three rules:

OPTICAL GUIDANCE

Current Road Standards require to provide a «response time» of 2-3 sec before the maneuver section

Human Factor based design practices require to provide an additional «anticipation time» of 2-3 sec before each critical point (for example: a roundabout requiring to slow down)

Distance covered during the maneuver

Lorenzo Domenichini

A road modification design ……

Design according to «stopping sight distance»

New roundabout substituting the existing intersection

Existing intersection

…. not compliant with the HF rule of Optical Guidance:

the anticipation time is missing

SPATIAL PERCEPTION

The value of parallel planting and guiding structures for the lane tracking task is generally not considered in design standards.

Exemple:A very nice Christmas card

…. but the gantry sign is not complying with HF rules of

spatial perception

Optical illusions are alsopresent along our roads

POSSBLE HF BASED COUTERMEASURES

Improve the driver guidance by the road carriageway

Lorenzo Domenichini

Improve the driver guidance along bends

Example:

DRIVERS’ EXPECTATIONS

If you don’t see it, don’t worry. The pre-programmation of your brain

doesn’t allow you to see it99% of people doesn’t see it

THERE IS SOMETHING STRANGE IN THIS PHOTO

….. what?

This finger should

be a thumb

Our brain is conditioned by the need (real or supposed) to act promptly. This induces us to go directly to the conclusions without having all the necessary information.

Motorway from New Delhy to Jaipur (India)

THIS ROAD has the geometric characteristics of a MOTORWAY.

But the ROAD OPERATION is similar to a LOCAL ROAD.

The ROAD CATEGORY the drivers perceive is «MOTORWAY» and therefore their LOGICAL EXPECTATIONS are those consistent with a MOTORWAY. Their driving behavior is the one considered possible for a MOTORWAY (high speed, no pedestrians, no driveways).

This road is one of the most accident prone road in the world.

Lorenzo Domenichini

A very frequent situation along the existing road network:a sharp bend at the end of a long straight

the drivers do not expect such a sharp bend and do not reduce speed in due time.

How to improve road safety?

DO YOU CONSIDER THESE MEASURES USEFULL?

ONE POSSIBLE SOLUTION:INCREASE THE OPTICAL DENSITY OF
