This evidence, and that contained in Note 3, is being used to inform scheme design and to support the development of analytical tools and modelling assumptions.

5

GM CAP: ANPR Surveys: Summary of Initial Findings

Sets out the results of an ANPR survey conducted in January 2019 at 42 sites across GM. The survey was designed to provide a representative profile of the vehicle fleet operating in GM in terms of vehicle type (including fuel used) and age profile, in order to update the previous data used in the OBC with a more comprehensive and robust dataset. The results show that there are not major differences between observed levels of compliance in the overall GM fleet between the 2016 and 2019 surveys. This data set is now being used widely as part of the ongoing work to refine the proposals as part of the FBC development for the CAP.

6

GM CAP: Behavioural response assumptions and available data sources

Sets out evidence gathered from a number of sources offering an insight into the vehicle markets in question and how they might respond to the range of measures proposed in the GM CAP. These include Stated Preference surveys that have been carried out by other CAP authorities (Sheffield and Bradford) and shared with GM. NOTE: This note contains early work on revised behavioural response estimates which is superseded by later work – see Note 37 and Report T4 for the latest assumptions.

7

GM CAP: LGV and HGV Operational Cost Models

'LGV and HGV Operational Cost Models’ describes a new analytical tool that has been developed in support of the GM CAP allowing the assessment of behavioural responses to a CAZ based on operational costs by vehicle type for HGVs and LGVs. It is proposed that this tool replaces the methodology for assessing behavioural responses as applied in the OBC.

8

Sets out what behavioural response assumptions were applied at OBC for HGVs, the revised behavioural assumptions proposed for future analysis based on the HGV Operational Cost Model, and proposed next steps for analysis. NOTE: This note contains early work on revised behavioural response estimates which is superseded by later work – see Note 37 and Report T4 for the latest assumptions.

9

GM CAP: LGV Behavioural Responses Note

'LGV Behavioural Responses’ sets out what behavioural response assumptions were applied at OBC for LGVs, the revised behavioural assumptions proposed for future analysis based on the LGV Operational Cost Model, and proposed next steps for analysis. NOTE: This note contains early work on revised behavioural response estimates which is superseded by later work – see Note 37 and Report T4 for the latest assumptions.

It sets out proposed next steps for analysis, including the development of an Operational Cost Model for Taxis (Hackney Cabs and PHVs). NOTE: This note contains early work on revised behavioural response estimates which is superseded by later work – see Note 37 and Report T4 for the latest assumptions.

11

GM CAP: Analysis of Bus Upgrade Options to Deliver Air Quality Compliance

Commercially sensitive so not for publication. 'Note 11: Analysis of Bus Upgrade Options to Deliver Air Quality Compliance’ was produced in response to a request from JAQU for analysis scaling the proportion of bus compliance required to deliver compliance. Practically, this approach is very difficult to test in a way that would represent a real-world operational scenario that could be delivered as part of the CAP. Note 11 therefore presents two approaches to understand the influence of buses on compliance with the Air Quality Directive: - how many of the GM bus service routes pass the predicted exceedance locations and the number of buses this represents compared with the GM bus operator vehicle fleet. - how many of the modelled exceedances would remain if the preferred option (Option 8) excluded bus improvements at all (i.e. a CAZ that did not include buses as a type of vehicle to be charged).

12

GM CAP: Evidence of the impact of 2021 implementation of a CAZ C (without exemptions)

Describes analysis carried out by GM to assess the risks of implementing a CAZ C in 2021 without also implementing a two-year sunset period as was proposed in the OBC. The Note sets out analysis of vulnerability by sector, based on the proportion of the fleet that would be non-compliant in 2021 compared to 2023; analysis exploring the risk of market distortion and the potential impact on small businesses; and analysis of the likely availability (or lack of availability) of second-hand compliant vehicles.

13

GM CAP: Study Traffic Impact on Neighbouring Authorities

Presents the results of highway modelling carried out to assess the likelihood and potential scale of traffic re-routeing to avoid a CAZ.

14

GM CAP: Local exceedances: Update

Sets out GM’s approach to identifying and assessing sites where further measures may be required in order to achieve compliance in the shortest possible time. The Note presents the results of analysis carried out to assess real-world traffic conditions and to compare these to model outputs, and analysis of NOx source apportionment and any local conditions affecting concentrations, such as canyons, including checking how accurate the representation of such conditions is in the model itself. It also sets out an update on work carried out to identify possible local solutions.

-

Technical Note 14a Appendix A

Appendix A to Note 14: GM CAP: Local exceedances: Update. Provides maps and data for each site considered in the local exceedances study.

15

GM CAP: Implications of the Emissions Factor Toolkit update for GM (EFT)

'Implications of the EFT update for GM’ considers the implications of Emission Factor Toolkit (EFT) version 9.1a, released by JAQU at the end of May 2019. GM’s methodology for calculating traffic emissions applies emissions factors has been derived from DEFRA’s Emission Factor Toolkit (EFT) version 8.0, which was originally released in November 2017. Version 9.1a of the EFT contains fleet figures which have resulted from a recent Department for Transport (DfT) project to develop new passenger car fleet projections in light of emerging evidence regarding changes in consumer purchasing behaviour which show a shift away from diesel cars and towards petrol cars, alongside a slowing in overall new car sales.

16

GM CAP: Sensitivity testing of a CAZ C in 2023 with revised behavioural response assumptions

Presents the results of a sensitivity test of the impacts of a CAZ C (without any supporting measures) in 2023, applying revised behavioural responses for HGV, LGV, PHV and Hackney Cab. The bus upgrade was assumed as 100% for the purposes of this test. This test was conducted at the request of JAQU. NOTE: Modelling contained in Note 16 was indicative modelling carried out at an early stage in the model development process and is superseded by the package modelling presented in Note 29, and Reports T4 and AQ3.

17

GM CAP: Evidence supporting the decision not to progress with a GM-wide CAZ D

Sets out the options appraisal process applied at OBC and presents further evidence explaining why it is not considered that a GM-wide CAZ D cannot bring forward compliance.

18
