• What we have done
• What we have learned
• What we might do differently
in future
MyCiti Starter
Service
• Buses
• Routes – Trunk & Feeder
• Stations & Stops
Buses
Trunk Route
• Table View to Civic Centre
• Dedicated bus lanes (red
lanes)
• Stations
Feeder Routes
• 3 Table View Routes & 1
Inner City Route
• Buses travel in mixed traffic
• Stops
Stations & Stops
Peninsula type
temporary Feeder
Stop with route and
bespoke timetable
Busways
Pavement Design
• ES 30 and ES 100
pavements
• Continuously
reinforced concrete
(CRC) preferred
– 190 mm to 280 mm
thick
• Modified asphalt
used at
intersections &
where services an
issue
Colourisation
• Assists with enforcement
• Concrete
– 5% Red Oxide
– Zero maintenance
• Asphalt
– Tyregrip with Jasper Chips
– High maintenace & costly
Colourisation
• Ultra thin friction course
Delineators
•
•
•
•
•
At speeds over
65km/hr kerb height
restricted to 150mm or
less
Flattest slope possible
should be used to
prevent tripping
100mm gaps required
for drainage every 2m
Kerb painted
retroflective yellow with
white line adjacent to
kerb line of general
traffic side
Require flashing cats
eyes at leading ends
where there is no
splitter island
Intersections & Signals
• Shared stop line
intersection
• Preferred layout
• Protected right turns
• ST boards
• Supplementary signage
“Right turn on red arrow
only”
Intersections & Signals
• Pre- signal
intersection
• Alternative layout
• Higher bus delay
• Supplementary
signage
“Pre-Signal – Stop
here when signal
red”
Intersections & Signals

•
Adherence to SARTSM –
not drafted with BRT in
mind
Driver adaptation to new
signals & bus priority
Bus signal aspect clarity
Adherence to red lights at
pre-signals
Removal of permitted
right turn
Adherence to ST arrows
on signals
Overcoming political
pressure to “increase car
delay” due to bus signals
Bus detector loop
positions
Urban Design
• City of Cape Town chose
the distinctive architecture
of the IRT stations to
– draw attention to the
station locations
– to be compatible with the
different urban
environments through
which the BRT routes
traverse
• Angled columns on
stations, totems and on
feeder stops use similar
architectural vocabulary
• Themed use of colour red
Before & After IRT:
Urban Improvement
& Colourisation of
lanes in Paarden
Eiland
Landscaping
•
•
•
•
Waterwise & indigenous plants
Robust & low maintenance plants
Treated effluent irrigation
Urban design focus at stations –
textured paving, bollards, bike
parking & benches
• Attractive customer environment
Bikeways
• 3m wide parallel NMT facility
• Marked as a bikeway between
intersections - asphalt
• Shared space at intersections –
textured (paving) & signed
• Thorns!!
• Visible bollards
• Wide range of users
Docking
Kassel Kerbs

•
•
Patented guidance kerb – Profilbeton in
Germany
Minimises tyre wall ware by 40%
Protects bus bodies from hitting station
platforms
Aligns buses with station platform to
ensure accurate docking
Polyeurithane moulds made in
Germany
Kerbs made locally under license
agreement
Local manufacturer – appointed
through tender process
Black pigment in concrete – reduce
signs of tyre residue on kerbs
Kassel Kerbs
Platform Separation
• Minimum spacing of
1.7 times vehicle
length
• Recommended
spacing 2 times vehicle
length
• At spacing of 1.7 times
vehicle length nose
sweep setback of
450mm recommended
– can be reduced for
greater spacing
• Tail sweep should be
checked – often less
critical than nose
sweep
• Need design vehicle
dimensions – calibrate
Autoturn

Separation
Nose Sweep
Guide Lines
•

Painted lines to
guide right hand
front wheel of buses
Facilitates swerve
docking at multiple
platform stations
Retroflective paint
with glass beads for
visibility in rain & at
night
Laser guidance?
Other guidance?
Driver compliance?
Alignment of Trunk
Bus with Platforms
Boarding Bridges
• Gap eliminated
• Flap down boarding bridges
• Threshold plates - can be designed
after bus fleet details are known to
achieve good fit for universal access
• Flab down bridges require specific
door opening & closing sequences to
prevent passenger injuries
Stations
Typical 3.5m
wide station
STADIUM
Airport
Signage & Totems
• Backlighting is required on Totems for
night time visibility
• Static and dynamic VMS signage is
useful for passenger information
• Route maps required in stations and on
buses
• “Prohibition and permission” signage
Bus Interface with Doors
• Communication between the bus and
station door
– opening signal system (including
software, microchips, wiring, etc) must
be excellent and failsafe otherwise we
will have poor service and potentially
unsafe conditions for passengers
• Addition of tiles with yellow arrows may
assist with queue management and
keep the doorways clear to speed up
safe boarding and alighting
• Still troubleshooting bus/station door
interface - reliability issue
• Operators tend to misuse station door
remotes
• Drivers have no visibility of bus doors –
line of sight from rear view mirror
Universal Access
• Tactile Paving
• Tonal differences are required for
partially sighted
• Considering tactile locality plans and
station maps
• Induction loops
Seating & Bum-rails
• Requests received from passengers for
seating in addition to bum-rails, where
feasible in stations
• Seating/benches in terminal stations
Unexpected
problems
• Terminal stations
– Feeder bus dispatch
– Need for bus stacking
– Need for operator staff accommodation
• Mops and brooms
• Bags and coats
• The winter chill
Kiosks
Kiosk Layout
• City of Cape Town insisted on a
bullet-proof cash office and a
universally accessible toilet on all
IRT stations
• Narrow stations in median create
design challenges with severe space
constraints
• Need main cashier/passenger
interface to be located at entrance
end of Kiosk so card purchase and
top up does not crowd the remaining
passageway to the gates
• Need adequate shelter at this
interface point
• Need system information and rules
at this point
• Litter bins?
Kiosk

Accommodation
• Prohibition and permission signage
• Distribution Board – accessible
• Accessible fire fighting equipment
Depots
Layout & Circulation
•
•
•
•
•
•
•
•
•
•
Clockwise circulation
Entrance and security
Refueling area
Chassis wash
Body wash & internal
vacuum,etc
Staging area
Training zone for docking at
mock station
Administration Building
Staff rest areas
Landscaping and staff
parking
• Maintenance building
– 3 bays per 100 buses (1 flat ;2
pits)
– Spray bay
– Offices, stores & staff facilities
• Parking
• Get experienced operator
advice – many small details
Layout
Inner City Bus Staging Area:
Considerations
• Reuse of bus
washing water
• Brake testing
equipment
• Mock station
(training)
• Universal access
• Modular design –
plan for expansion
• Plan for more than 1
operator
• Block vs angled
stacking
• Prayer room, kick
about etc
Stops
Shelter Types
•
•
•
•
Pole
Standard
Cantilever
Standard extended
Considerations
• Buses stop in slow lane
– In line
– Nub or Bump-out
• Embayments used on very busy 2
lane arterials
• Combination of shelter and stop types
gives 16 physical designs
• Inner city – unique designs
• Temporary stops help test locations
• Bus priority along congested routes
• Adjust stop lines/keep clear boxes to
assist bus turning
• Stop locations too near intersections
Eliminate the Gap
• Reduce or eliminate gap for
wheelchair users & others with
disabilities (at left hand bus
door opposite driver)
• CD style mini ramps being
considered
– 350 mm ramps deploy in 5 sec
– Require regular maintenance
– Flap down bridges not “safe” in
open environments
• Low floor buses vs very low
floor
– 340 mm ride;270 kneel
– 280mm ride;200 kneel
Universal accessibility
One of the reasons people
cannot mobilise
themselves is that they try
to accomplish great things.
Most worthwhile
achievements are the
result of many little things
done in a single direction
Thank you
