Developing a methodology to
quantify emissions associated with
excess capacity in urban transport
systems
Clare Linton, pmcli@leeds.ac.uk
Dr. Susan Grant-Muller
Prof. William Gale
Overview
• Background and context
Defining capacity
The case study area - Greater Manchester
• Approach
Socio-technical system and capacity
• Developing a framework to quantify capacity and emissions
• Future work, Summary and Conclusions
Background Approach Framework Conclusions
Background and context
• Urban transport
dominated by private car
travel and flow is
concentrated into peaks
• Average UK car
occupancy is 1.6
persons
• Collaborative consumption uses resources more
sustainably and could help utilise excess transport
capacity
Data from (Department for Transport, 2012)

Defining Capacity
• This work defines capacity as the space within the transport
system through which transport demand can be met
• This refers to physical space, both within vehicles and the
roadspace, which can facilitate mobility.
• There are also elements of temporal capacity, with periods
of high and low loading
Background Approach Framework Conclusions
Research Questions
1. How much excess capacity is there within the urban
transport system?
2. What is the potential for enhanced use of excess capacity
to deliver emission reductions?
3. How can the principles of collaborative consumption be
applied to examine excess capacity in the urban transport
system?
Background Approach Framework Conclusions
Greater Manchester
• Greater Manchester is the
case study area
Large metropolitan county in
NW England
Covers 1276km2
2.6 million residents
10 local authorities
• The framework is applicable
to other urban areas in the
UK and beyond
Background Approach Framework Conclusions
Approach
• Socio-technical systems
capture the range of
technological and socio-
economic factors involved
in a complex system such
as transport
• This figure shows the
factors involved in urban
transport capacity
Socio-technical configuration for urban transport
capacity (adapted from (Geels, 2002))
Background Approach Framework Conclusions
• This figure shows the
elements that are captured
in the current framework
presented here (those
excluded are in greyed
italics)
• Additional factors are
incorporated in future work
and others are included as
exogenous factors

Background Approach Framework Conclusions
The framework
• The following section presents the framework for
quantifying excess capacity in urban transport systems and
the potential emission reductions.
• This is done mainly through the presentation of a flow chart
and more detail about the inputs, processes and outputs
Background Approach Framework Conclusions
Flow chart of framework
Flow chart of framework
Inputs to the framework
• Survey
500 residents of Greater Manchester
Questions include information about journeys in last 7 days, mode,
journey purpose, time of day and occupancy rates
Survey conducted by Accent MR
• Fleet Data
Vehicle available space (number of seats / standing room)
Vehicle fuel type
Vehicle size
Emission factors
Background Approach Framework Conclusions
Flow chart of framework
Outputs from the framework
• The main outputs are:
• Fractional vehicle excess capacity (for individual modes
and a mode weighted value)
• CO2 emissions (per person per week)

Background Approach Framework Conclusions
Future work within this project
• Scenario construction for future use of urban transport
capacity in emission reductions
• Traffic network modelling of capacity scenarios
• Additional indicators of capacity
Roadspace capacity
Delays and congestion
Background Approach Framework Conclusions
Conclusions
• Options available for utilising excess capacity include car
sharing and re-allocation of roadspace for public transport
• Given current occupancy rates for cars and buses, between
60-89% of capacity is excess
• It remains to be seen what the rebound effects and impacts
of induced congestion might be
• Achieving an 80% reduction in emissions by 2050 is
challenging, using excess capacity could contribute to this
Background Approach Framework Conclusions
Thanks for your attention

Developing a methodology to quantify emissions associated with excess capacity in urban transport systems

  • 1. DTC Low Carbon Technologies FACULTY OF ENGINEERING Developing a methodology to quantify emissions associated with excess capacity in urban transport systems Clare Linton, pmcli@leeds.ac.uk Dr. Susan Grant-Muller Prof. William Gale
  • 2. Overview • Background and context Defining capacity The case study area - Greater Manchester • Approach Socio-technical system and capacity • Developing a framework to quantify capacity and emissions • Future work, Summary and Conclusions Background Approach Framework Conclusions
  • 3. Background and context • Urban transport dominated by private car travel and flow is concentrated into peaks • Average UK car occupancy is 1.6 persons • Collaborative consumption uses resources more sustainably and could help utilise excess transport capacity Data from (Department for Transport, 2012) Background Approach Framework Conclusions 0 200 400 600 800 1000 1200 1400 1600 1800 Numberofvehicles Vehicle Mix A34 Manchester (both directions, weekday) HGV LGV Buses/Coaches Cars Motorcylces Pedal Cycles
  • 4. Defining Capacity • This work defines capacity as the space within the transport system through which transport demand can be met • This refers to physical space, both within vehicles and the roadspace, which can facilitate mobility. • There are also elements of temporal capacity, with periods of high and low loading Background Approach Framework Conclusions
  • 5. Research Questions 1. How much excess capacity is there within the urban transport system? 2. What is the potential for enhanced use of excess capacity to deliver emission reductions? 3. How can the principles of collaborative consumption be applied to examine excess capacity in the urban transport system? Background Approach Framework Conclusions
  • 6. Greater Manchester • Greater Manchester is the case study area Large metropolitan county in NW England Covers 1276km2 2.6 million residents 10 local authorities • The framework is applicable to other urban areas in the UK and beyond Background Approach Framework Conclusions
  • 7. Approach • Socio-technical systems capture the range of technological and socio- economic factors involved in a complex system such as transport • This figure shows the factors involved in urban transport capacity Socio-technical configuration for urban transport capacity (adapted from (Geels, 2002)) Background Approach Framework Conclusions
  • 8. • This figure shows the elements that are captured in the current framework presented here (those excluded are in greyed italics) • Additional factors are incorporated in future work and others are included as exogenous factors Socio-technical system and capacity Socio-technical configuration for urban transport capacity (adapted from (Geels, 2002)) Background Approach Framework Conclusions
  • 9. The framework • The following section presents the framework for quantifying excess capacity in urban transport systems and the potential emission reductions. • This is done mainly through the presentation of a flow chart and more detail about the inputs, processes and outputs Background Approach Framework Conclusions
  • 10. Flow chart of framework
  • 11. Flow chart of framework
  • 12. Inputs to the framework • Survey 500 residents of Greater Manchester Questions include information about journeys in last 7 days, mode, journey purpose, time of day and occupancy rates Survey conducted by Accent MR • Fleet Data Vehicle available space (number of seats / standing room) Vehicle fuel type Vehicle size Emission factors Background Approach Framework Conclusions
  • 13. Flow chart of framework
  • 14. Outputs from the framework • The main outputs are: • Fractional vehicle excess capacity (for individual modes and a mode weighted value) • CO2 emissions (per person per week) Background Approach Framework Conclusions
  • 15. Vehicle Average Occupancy Comfort Case Extreme Case Available Space Associated Excess Capacity Available Space Associated Excess Capacity Car (national average) 1.6 4 60% 5 68% Car (GM peak) 1.22 4 70% 5 76% Car (GM off peak) 1.36 4 66% 5 73% Local Bus (national average) 9.5 70 86% 85 89% London Bus 19.3 70 74% 85 77% Examples of vehicle fractional excess capacity Background Approach Framework Conclusions
  • 16. Future work within this project • Scenario construction for future use of urban transport capacity in emission reductions • Traffic network modelling of capacity scenarios • Additional indicators of capacity Roadspace capacity Delays and congestion Background Approach Framework Conclusions
  • 17. Conclusions • Options available for utilising excess capacity include car sharing and re-allocation of roadspace for public transport • Given current occupancy rates for cars and buses, between 60-89% of capacity is excess • It remains to be seen what the rebound effects and impacts of induced congestion might be • Achieving an 80% reduction in emissions by 2050 is challenging, using excess capacity could contribute to this Background Approach Framework Conclusions
