STATE OF FATALITIES IN SOUTH AFRICA
Low Value of Human Life
• NMT users account for 40% of
road fatalities in South Africa
• Scholars mode of transport
19% PT; 12% PVT; 69%
Walking
• Majority of all NMT-related
accidents occur at
intersections
• NMT casualties costing the
public health system; police
and traffic departments; third
party claims etc

ASK OURSELVES……….
• Ask ourselves : Do we want to live like this?
• Do we want cities for cars or cities for people?

SUSTAINABLE TRANSPORT IS NOT….
• Diminishing non-renewable (petroleum) energy reserves
• Global atmospheric impacts – air pollution
• Local air quality impacts
• Fatalities and injuries
• Congestion
• Noise
• Low Mobility
• Biological Impacts
• Lack of equity WR Black

• City of Joburg is implementing a new
approach to ward based safety
• Focus on safer streets – not just
random speed humps
• Supporting a paradigm shift from
roads to streets : COMPLETE STREET
CONCEPT
• Definition of a street : sense of place
(social activity); movement; access to
buildings and public spaces; parking ;
utilities and street lighting
COMPLETE STREETS CONCEPT
![Page 9: Complete Streets : Reshaping the Way We Think about Urban ... Africa... · •Complete streets accommodate diverse modes, users and activities •Promotion of pedestrian and other](https://reader033.vdocument.in/reader033/viewer/2022060213/5f05384e7e708231d411e03e/html5/thumbnails/9.jpg)
• Complete streets
accommodate diverse modes,
users and activities
• Promotion of pedestrian and
other non-motorised modes of
transport
• Street design which helps
create multi-modal transport
systems and liveable
communities

COMPLETE STREETS CONCEPT (3)
• Contribute to liveable, vibrant, sustainable communities :
by providing public open space that is integrated amenities, as well as having well-
connected neighbourhoods which reduce dependence on motor vehicles, will
ensure increased personal security, will lead to a sense of ownership
and high quality
environments

• Pedestrian first policy
– The walking public are given priority
• Modal Hierarchy
– Modal hierarchy will remain as NMT first; Public transport; motor vehicles.Modal hierarchies influence cross-sections, intersection design, signaltimings, maintenance programmes
• Typology
– Based on the function of the street and
the roadway width
– encourage pedestrian activity.
• Design Values
– Design guidelines are provided for each
element, which support complete streets
HOW DOES THIS LOOK LIKE PRACTICALLY?

• Speed reduction through street design
• Care at intersections : road diets / narrower lanes; kerb extensions; traffic
signal timing; median islands
• Creating rhythms with trees, poles, landscaping

WHERE CAN WE START (3)
Opportunities to:
• Restripe or slightly widen shoulder for bike lanes through intersections;
• Install sidewalks for pedestrians (both at intersections and to connect different approaches);
• Provide crosswalks;
• Add pedestrian refuges or islands;
• Install curb ramp upgrades/additions to comply with universal design standards
• Incorporate other complete street amenities E.G. street furniture
• Traffic signal installation/upgrades:
– Install pedestrian signal heads and countdown equipment;
– Retime signals to allow for pedestrian phases and/or improve pedestrian safety;
– Incorporate accessible pedestrian crossing signals;

WHERE CAN WE START (4)
• Pavement restriping (similar to maintenance projects):
– Convert streets or use road diets to provide a full bike lane or pedestrianised streets;
– Reduce lane widths to provide a full bike lane;
– Stripe pavement for a shoulder/edge lines on streets with curb and gutter (may be in conjunction with a street conversion or as a standalone maintenance project);
• Thoroughfare widening:
– Widen street for striped bike lanes with protective separators;
– Widen/pave shoulders to provide wider outside lane, paved shoulder;
– Construct sidewalks to adequate widths and standards; and/or
– Incorporate other complete street amenities or technologies
– Provide bicycle parking / bus shelters / seating at public transport stops / adequate provision for public transport users along streets
