New open data: Busiest times at Blackwall Tunnel

The Blackwall Tunnel (A102) is one of the busiest places on London’s road network. In recent years, journey times have increased and drivers can expect delays to their journey at some times of day. We’ve released this data to the open data community, to enable developers to build the information into their products.  

Our data shows the busiest times at Blackwall Tunnel so developers can include this information in journey-planning apps

What our data shows

*Follow this link to find the data.

1)    The busiest time in the northbound tunnel on a weekday is from 07:00 – 07:30. In heavy traffic conditions, drivers’ journeys could be 15 minutes quicker if they travelled between 06.30-07.00 instead of 07:00 – 07:30.

2)    The busiest time in the northbound tunnel on a weekend is from 13.30 – 15.00. In heavy traffic conditions, drivers’ journeys could be 15 minutes quicker if they travelled between 12.00-13.00 instead of 13.30- 15.00.

We have made this data available to the open data community so you can use it to create products which display the busiest times at the tunnel, allowing drivers to choose to travel outside of these periods or create products for planning quicker and more reliable journeys.

Tell us what you think

We encourage the community to provide feedback on our new data sets to help us continue to enhance and improve our open data products. Please let us know your thoughts in the comments section below or on our tech forum.


Tower Bridge Closure – Data Set Released

The City of London Corporation are planning essential major maintenance works to Tower Bridge. The work will require a full closure of the bridge to all vehicle and cyclist traffic for three months. The closure will be in place 24 hours a day, 7 days a week from Saturday 1 October to Friday 30 December 2016.

As part of our open data policy, we’re releasing a full data set of the closure to allow developers to easily incorporate this data into their apps, helping Londoners to plan their journeys while the works are ongoing.

London Data City | Data Nation Challenge – Extra Info

As previously posted on this blog, London Data City | Data Nation was launched on 12 April, with a series of 6 month-long challenges being undertaken by teams in London and Singapore.

The first in the series of challenges is the Transport and Mobility challenge, which is now underway and runs until Monday 16 May.

At the launch event for the challenge Rikesh Shah, Lead Digital Relationship Manager at TfL, introduced our open data policy and set the scene for the challenge. Following up on the launch event, Rikesh has a message for the participants with some handy extra info:

Dear all,

I hope you’re all enjoying the challenge.

At the launch of the Data Nation challenge I promised that I would provide more information about TfL, with a particular focus on customer insight. So, I am delighted to provide a link to some useful information.

In particular, have a look at Chapter 7 which focuses on Customer Experience.

Good luck!

All the best,

Rikesh Shah,
Transport for London


Data City | Data Nation Launch – The Challenge is Underway

The London Data City | Data Nation challenge was launched on the morning of Tuesday 12 April at an event hosted by Digital Catapult. The launch event outlined the context and details of the 6 month-long challenge being undertaken by teams in London and Singapore, starting with the Transport and Mobility challenge that runs until Monday 16 May.

In partnership with TfL, the Greater London Authority and Ford, Digital Catapult are setting challenges based around 2 key questions:

Public Transport Challenge

How can we accurately identify, filter and characterise transportation delay events across large-scale, dynamic, multi-modal transportation systems?

Enabling users to make seamless progress towards their destination. People need help to very quickly identify breaks in the system and need greater help for decision making in case the system breaks and when to abandon their plans for a better option. Participants need to choose data sources (from sandbox or beyond) to achieve the end goal.

Road Network Challenge

How can we enhance customer service and experience across London’s road network?

Through Data City | Data Nation we intend to deliver new technology solutions that help understand and predict events on London’s road network and go about enhancing the overall customer experience whilst travelling that network. TfL will provide SCOOT traffic data (described in more detail here) to participants of the challenge that is not yet publicly available.

We’ll update this blog as key milestones in the challenge are met, and will of course announce the winners in May. Good luck to all taking part!

Setting the scene for the challenge

There were many expert speakers setting the context and details of the challenge, and their presentations are summarised below.

Traffic Data Hack Day – Event Review

As previously outlined in our post on March 30 on this blog, the Traffic Data Hack Day was hosted by Amazon Web Services on April 6. The event was attended by TfL employees, academics working within this subject area, data scientists, transport app developers and data visualisation developers.

Another key event in our engagement with those working with our open data, the day was split into two areas, with one focussed on visualising TfL data and the other on extracting data from the source and providing it for analysis.

I’ve not attended a hackathon or hack day before, so it was really interesting to see how they work and to meet participants from all sorts of backgrounds, including universities, consultancies, government agencies and other parts of TfL.

At the beginning of the day we split the focus into two areas; ‘EMR (Elastic Map Reduce)’ where the group was looking at ways to improve the feed of, access to and processing of the SCOOT data and ‘Redshift’ where the group made use of data that had been uploaded to the system and was ready to analyse.

Data City | Data Nation – Transport and Mobility Event


Join us for the launch of the London Data City | Data Nation transport and mobility challenge on Tuesday 12 April. Hosted by Digital Catapult, this event will set the scene for the challenge with industry stakeholders and keynote speakers alongside leading transport organisations.

TfL have agreed the challenges with Ford, the other partner for this event, and we’ll also be providing expert speakers and judges and offering technical support to the participants. We’ll be providing open data from our Unified API as well as the historic Traffic Data Enquiry System (TDES) data generated by SCOOT traffic sensors across London (which detect traffic flows at junctions and then optimise traffic signals every second to help keep vehicles moving).

Our TDES data hasn’t been made publicly available yet, so we’re hoping to see some great innovative solutions to some of the key transport and mobility challenges, from participants both in London and Singapore.

This event is another example of our continuing commitment to open data with over 8,000 registered users, as well as our determination to open up our data and support the developer community as much as possible to help create great products and solutions that help London keep working and growing, and make life in the city better.

Traffic Data Hack Day – Register Now

**Registration for this event is now closed**


TfL’s Urban Traffic Control System (UTC) uses 12,000 sensors located at junctions across the Capital to measure traffic flow. The data produced is used to drive SCOOT – the traffic light optimiser system – and on Wednesday 6 April we’re aiming to generate greater value from this as-yet untapped data source.

We want to configure a data processing engine for UTC data and begin exploring this large data set using the tools business users are familiar with, such as R Studio and Tableau, as well as event streams, map reduce type platforms and machine learning tools.

The event is part of our ongoing drive to work with the dev community to create great products from our open data, and offers an opportunity to learn and experiment with cloud tools in a safe, sandbox type environment. Experts from TfL’s Road Space Management team will be on hand to provide support.

Where and when

Venue: Amazon Development Centre, Leadenhall Court, One Leadenhall Street, London, EC3V 1PP

London Collision Map and Improved Cycle Journey Planning

As part of a wider road safety strategy, last week we launched the London Collision Map and London collision data on our website and in our API, as part of our ongoing commitment to providing open data. We’ve also made improvements to cycle journey planning.

The new cycle journey planning features include:

  • Google street view images at every turn of the route to help cyclists prepare a ‘mental map’ of their route and visualise junctions before they make their journey.
  • The location and details of cycle parking at London rail stations including information on the number of potential spaces, the type of cycle parking and whether it is covered.
  • ‘Cycle route classifications’ for each section of the journey describing the type of cycling environment that cyclists will encounter along their route (e.g. Cycle Superhighways or routes through parks) helping them to be more informed about the journey they will be making.
  • Identification of steep hills along the route.

The other new feature, the London Collision Map, allows searches for road collisions across London, providing information about when and where they occurred, as well as the severity of the incidents, dating back to 2005. It uses STATS-19 casualty dataset, collected annually by the Department for Transport, and shows a significant reduction in the number of collisions over time.

Through this data we’re able to inform people about junctions and roads that have high numbers of collisions, and where road users should be particularly careful. The 2014 figures show that this number fell to its lowest level since records began, in line with the Mayor’s target to halve the number of people killed and seriously injured (KSI’s) by 2020.
