1) reduced capacity on public transport 2) need for space so physical distancing guidelines can be followed
3) healthy restart 4) need to act fast. Image credit: [TfL](https://twitter.com/W_Bradley/status/1268836932219478016).

### Existing cycleways

- Aims to identify **immediate** issues
- From OpenStreetMap, March 2020
- Contains sections of variable quality
- Aim to highligh where gaps need to be filled

### How to identify ‘top ranked new cycleways’?

<!-- ![](figures/results-top-leeds.png) -->

- Aims to identify **short term priorities**
- All road sections with spare lanes or estimated width > 10 m (CyIPT)
- Of those, which have a minum continuous length of at least 500 m?
- Rank the roads by cycling potential (commute + school, Government Target)
- Show the top n, where n depends on the size of the region (70 in London)

Tablular results for Leeds

```{r, echo=FALSE, out.height="100%"}
res_leeds = sf::read_sf("https://www.cyipt.bike/rapid/west-yorkshire/top_routes.geojson")
res_table = res_leeds %>%
  sf::st_drop_geometry() %>% 
  arrange(desc(mean_cycling_potential))
# %>% 
#   select(
#     Name = name,
#     Reference = ref,
#     `Length (m)` = group_length,
#     `Cycling potential` = mean_cycling_potential,
#     `Length * potential (km)` = km_cycled,
#     # `SRN` = srn,
#     `Speed limit` = speed_limit,
#     `Mean estimated width (m)` = mean_width,
#     `Majority spare lane(s)?` = majority_spare_lane
#     ) 
DT::datatable(res_table, height = 600)

### How to identify a ‘cohesive network’?

- Aims to support **long term planning**
- Intended to show what a joined-up cycle network could look like if we were to consider new cycleways by either closing roads to motorised traffic or creating one-way systems
- Find  roads that have high cycling potential on some or all of their length
- Join them up

# How should I use these results?

- Aim: to support evidence-based prioritisation of bids for Tranche 2 of the Emergency Active Travel Fund
- Complementing local knowledge and stakeholder engagement
- Scoping of options
- Order of implementations

Investment should depend on many factors including:

- cycling potential (default metric to rank schemes)
- total length of cycling infrastructure created
- cycling potential multiplied by road section length

## Limitations

- Narrow focus on road space reallocation options
- No economic appraisal
  - Use the Active Mode Appraisal Toolkit ([AMAT](https://www.gov.uk/government/publications/tag-social-and-distributional-impacts-worksheets)) 
- The best locations for new cycleways may not always have space
  - Search for parallel routes, which may be available
- Many options not in top routes
  - see cohesive network and look for other option
- The road network data is from 2017 and widths are estimates
  - Compare with real world knowledge
- Only work and school trips included
  - Use local knowledge of new developments and other 'trip attractors
- Prioritises routes in large cities in authorities with multiple settlements
  - Use alternative sources of information, including the PCT
  - Do additional analysis, e.g. based on data downloaded from the Rapid tool or the PCT
