CONTENTS

• Transport that requires human energy. These are in the form of walking, bicycles, tricycle etc.

• Animal power for example, horse drawn carts, donkey carts, bullock cart, horse riding etc.

• long/short trips in rural/urban areas.

• Access to mechanized modes of transports.

• The recognition of NMT as a major mode of transport is embodied in a number of national, provincial and municipal legislation, policies, master plans and frameworks and need to be taken into consideration by NMT Planning and for universal access.

Non-Motorised Transport (NMT)

One of the strategic objectives for Land Passenger Transport that is presented within the White Paper on National Transport Policy, 1996:

“ensure that passenger transport services address user needs, including those of commuters, pensioners, the aged, scholars, the disabled, tourists and long distance

passengers”

This is affirmed in all the following constitutions, conventions, acts etc;

• The Constitution (Act No 108 of 1996)

• The SA adopted UN Convention on the Rights of Persons with Disabilities and Optional Protocol

• The Promotion of Equality and Prevention of Unfair Discrimination Act, 2000 (Act No 4 of 2000)

• The National Land Transport Act, 2009 (Act No 5 of 2009)

• The Integrated National Disability Strategy White Paper, Nov 1997.

• The National Development Plan targets

Strategic objectives for public transport and supporting legislation

The Public Transport Strategy outlines the process towards achieving universally accessible transport.

• This process is to be incremental, with new systems achieving universal access from the outset, and with existing services upgrading to the same standard within a similar timeframe.

CURRENTLY Billions spent on • NMT Projects (Footways & Cycle ways) and

• 13xBRT Projects that includes NMT, UA

ACHIEVING UNIVERSAL ACCESS (UA)

Universal access or design improves facilities for all people in all ages, stages of their lives and health.

(Not FOR Disabled)

Ideas and concepts that is applied to the built environment to achieve better aesthetics, more usable and accessible environment to the greatest extent possible to all people, regardless of age, ability, status in life, pushing a trolley or a pram, temporary illness or injury, any kind of impairment, be it visually, mobility or hearing impaired.

Totally remove obstacles that can hinder the progress of any person trying to get from point A to point B, be it rural or urban, throughout the entire travel chain.

UNIVERSAL ACCESS (UA)

• Address only the aspect of universally useable design. The practice of design involves more than a consideration of usability, and should also take into account other considerations such as economics, engineering, culture, gender and environmental concerns.

• Equitable Use; useful and marketable to people with diverse abilities

• Flexibility in Use; accommodates a wide range of individual preferences and abilities.

• Simple and Intuitive Use; easy to understand, regardless of the user’s experience, knowledge, language skills, current concentration levels.

• Perceptible Information; communicates necessary information effectively to the user, regardless of ambient conditions or the user’s sensory abilities.

• Tolerance of Error; minimises hazards and the adverse consequences of accidental or unintended actions

• Low Physical Effort; can be used efficiently, comfortably and with minimum fatigue

• Size and Space for Approach and Use; Appropriate size and space is provided for approach, reach, manipulation, and use regardless of user’s body size, posture or mobility.

• One of these facilities included into the infrastructure is the kerb ramp to assist people with special needs to access the footway and cross roads etc.

HOW? – BY PROVIDING WELL DESIGNED FACILITIESFOR NMT USERS

OK, THAT’s EASY, JUST ADD A RAMP….

UNFORTUNATELY NOT

NoWarning !Warning

TACTILE GROUND SURFACE INDICATORS (TGSI’S)

Way-finding system included in external or Internal pedestrian surfaces.

• Warn pedestrians of imminent hazards, such as warning the pedestrian of a dropped kerb at a pedestrian crossing and direct person on direction to cross the road.

• Guide pedestrians along defined routes.

• Guidelines from the following countries were all included in the investigation to date: South Africa, Mozambique, Malawi, India, Asia, North & South America, China, Ecuador and Europe

None of the above mentioned documents indicates the currently suggested design of tactile pedestrian crossing according to the SANS 784 Standard.

WHAT IS OUT THERE ?

Where did the Blisters come from ?

INCORRECT PROFILE

• SANS 784: 2008 Design for access and mobility -Tactile indicators;

is an Australian and New Zealand Standard which was adopted by SA in 2008 (Pre Soccer World Cup),

but is actually a 2002 Standard on Disability Discrimination.

(14 Year Old Standard)

Is currently going through a review and consultation process to rewrite in SA. Has already been updated in AU/NZ.

In order to design them correctly, you need to know;

• What the components are;

• Blocks, (Warning, Guidance)

• Buffer

• Gradient & Levels

• Transitions

• Landing

• How they function or assist a person that is blind or partially sighted.

• Controlled and Un‐Controlled

• Detect

• Guide

• Warn

• Direct

• REMEMBER; • Desktop study• Workshop

• Some site work

• Practical work experience

• Taking all the principles and international examples researched

• Using what was already happening in South Africa

• Merging layouts in a sensible way

TACTILE PEDESTRIAN CROSSING FOR SOUTH AFRICA

BUT Where does THIS layout come from?

Complies to and incorporates international best practice, consultation with (NDoT), (SABS), UA Consultants and some disability alliance groups including (SANCB + some Subsidiaries).

This is crucial to ensure consistency and uniformity in design and layout throughout South Africa.
