Our ref: FOI-1010-2122/GH

Thank you for your request received by Transport for London (TfL) on 19 July 2021 asking for information about Cycleway 9.

Your request has been considered under the requirements of the Freedom of Information Act 2000 and our information access policy. I can confirm that we do hold the information you require.

Overall Cycling: Our data shows that cycling is one of the only modes of transport to have increased during the pandemic, with current cycling levels around 40% up compared to the baseline. Our data shows particularly significant increases at weekends, of more than 200% in certain locations. 

We are continuously monitoring a sample of cycle sites across London using automatic cycle counters.

Our data shows that the average daily cycle count for this sample was 2,937 for the week 9th to 15th June 2021. This is an increase of 40% on the average daily cycle count of 2,076 for the same sample of sites in the equivalent week in 2019.

Weekend increases for the whole sample have exceeded 200% on several occasions (13th-14th June 2020 where the average daily cycle count for the sample was 3,460 compared to 1,148 for the equivalent week in 2019, 20th-21st February 2021 with 2,371 vs 745, and 27th-28th February with 2,532 vs 739).

Chiswick High Rd Cycling: Data for Chiswick High Road shows that up to 2,700 people are now cycling at weekends, including families and children. The number of people cycling is growing and there were 72% more cyclists on weekdays in April 2021 than in February 2021. Cycling is now an important transport mode allowing people to safely get around and in April 2021 daily counts showed that people cycling made up 20% of all ‘vehicles’ on Chiswick High Road.  

We have been monitoring cycles on Chiswick High Road using camera footage since December 2020. The data “up to 2,700 cyclists” was for Saturday 27th February 2021. On this day our monitoring captured 2,746 cycles 6am-10pm.

The average daily weekday (6am-10pm) cycle flows for February, March and April were 1,239, 1,598 and 2,125. The increase between February 2021 and April 2021 was therefore 72%.

Our monitoring also counts buses, taxis (black cabs), cars, motorbikes, LGVs, OGVs and pedestrians. In the April 2021 counts, cycles comprised 19.9% of the total vehicles counted (i.e. excluding pedestrians) 6am-10pm on weekdays.

Bus Journey Times: The recent increase in car use in west London is at certain times in some locations leading to longer traffic queues and slightly slower bus journey times (in May 2021, bus journey times were up to 1.3 minutes per km slower than the average in 2019).  

We have been monitoring bus journey times along Chiswick High Road and surrounding roads. For the 4 weeks in May 2021, the average journey time eastbound along Chiswick High Road (between Chiswick Flyover and Dalling Road) was 5.7 min/km. This compares to the pre-Covid baseline (March 2019-March 2020) of 4.4 min/km, meaning bus journey times were 1.3 min/km slower.

If this is not the information you are looking for, please do not hesitate to contact me.
