Parking Capacity

Parking and DFDS

Capacity

Capacity Problems– Rail

Capacity• Link loads reach maximum between Centurion and

Sandton

• Highest link load in Midrand – Marlboro section

• Capacity under pressure for about 1½ of the 3 hour

peak period per day

• Counter flow services are underutilised

• Options on current train timetable exhausted

• Rolling stock availability under pressure

• Challenge is how to alleviate capacity constraints

Capacity Problems– Rail Layout• A double-line section shared by the North-South and

East-West

• Junctions at Marlboro Portal - East-West and North-

South services are merged / diverged.

• Single-line tunnel sections between Sandton and

Rosebank

• An at-grade crossing between Pretoria and Hatfield

• Scheduled crossing in the platforms at Rosebank

Station

• Terminal stations restricted to two platforms each

• No loop lines outside the depot area

• Long signalling blocks

Capacity Problems– Parking &

DFDS• Parking

• Parking capacity is insufficient - Pretoria, Centurion,

Midrand, Park, Rosebank and Rhodesfield.

• Availability of land at stations

• Cost of development vs Recovery/Cost to customers

• DFDS

• J2 Johannesburg CBD and M3 Sunninghill-

Overcrowding

• Long bus cycle times

• The DFDS bus service footprint

Considerations

&Conclusions

Capacity Problems– Trade-off

Consideration• Longer trains are more labour efficient

• Shorter trains are more energy efficient

• Pressure on the available line capacity of the network

• • Higher capital and maintenance costs

• The capital cost of doubling of an existing single tunnel

• Higher service levels/ Consequential delays

• Seating Capacity ratio of 1.50 vs. 1.3 vs Cost of service

• Jumper/step back drivers could alleviate capacity

problems on platform and line capacity.

Capacity – Assessment &

Conclusions Rail• That 84 additional rolling stock coaches - required by 2026

• Longer platforms would be required at OR Tambo - 2013

• The Rosebank to Park Station single tunnel - full capacity

by 2022

• The Sandton to Rosebank single tunnel, full capacity by

2026

• Staging capacity at maintenance depot in Midrand -2016

• The provision of additional line capacity between Marlboro

portal and Sandton - required by 2029

• high level junction capacity at Pretoria station - reach

capacity by 2018.

Assessment & Conclusions

Stations, DFDS & Parking• The station design capacities under pressure

• OR Tambo Station (from 2013),

• Park station entries (2014),

• Midrand Station entries (2015),

• Sandton Station exits (2016).

• Additional parking would be required at seven of the nine

station in the next 5 years

• Centurion (824),Rhodesfield (535),

• Midrand (363), Pretoria (253),

• Hatfield (187), Rosebank (148) and Park (70).

• Adititonal busses and routes will be required by 2019

Recommendations

Timelines

Capacity – Recommendations• 48 rolling stock coaches are procured starting 2015

• OR Tambo platform be extended - 2014

• Rosebank to Park and Sandton to Rosebank single tunnels be

doubled - 2021

• New Depot Staging capacity at the depot in Midrand to be

increased

• Line capacity between Marlboro and Sandton is increased by

2018

• Investigate Centurion – Sandton short turn shuttle service

• A full simulation study of the system to determine bottlenecks

• Configure the seats in GPS train sets – 2014

• Shorter headway and the rolling stock implications

Capacity - Future actions• Network Assessment will be updated on an annual basis

• Integrate land-use strategies for all stations

• Determine the long-term GMA financial implications

• A full transport integration strategy to be finalised

• Prioritise the different activities and create a scheduled

project plan

• Finalise the rolling stock procurement tender

• Finalise the physical infrastructure system optimisation

• Finalise new DFDS routes and add new shuttle services

• Develop a full integrated plan to incorporate NMT and UA

Mobility Paradigm

SUSTAINABLE MOBILITY PARADIGM

TRANSPORT TRENDS

• Sustainable Urban Mobility Planning

• Total Carbon Footprint of Public Transport and Mobility

• The convergence of Public and Personalised Transport

• Smart Mobility

– The First/Last Mile is key in Trip Planning

– Influencing Commuter Behaviour

• Data Centric Mobility

– System Convergence and Standardisation

• Availability of Information

– Information today is pervasive

– Web technologies catalyse instant and standard access

– Smartphones/tablets catalyse personal access

– Open Data

• Designing for Sustainability

– SMRS

– Future Materials

COMMUTER CONNECTIVITY REQUIREMENTS

• Trip planning

• E-commerce – Ticket reloads

• Overall Service Status (Live)

• Next Arrival for Bus and Railway (Scheduled)

• Service maps for bus and train

• Weather reports – Morning and Evening

• Universal Access - Elevator and Escalator Status

• Neighbourhood and station navigation

• Reduced mobility Alerts – Roadworks and Detours

• Emergency messaging

• Advertising/Institutional messages

• Customer Queries

• Camera and microphone for Customer Service - FaceTime

PERSONALISED TRIP INFORMATION REQUIREMENTS

• Provide real-time multimodal information

• Users expectations of a seamless journey with timely traveller

information

• Last mile Connectivity

• Information system data needs to be effectively integrated to make

the information valuable

• User experience

• Intuitive

• Interactive and Adaptive screen

• User Interface – Standardised look and Feel

• Provides a snapshot of various real-time information in default

mode
