Barnet is in the process of developing a transport strategy to understand and improve the way individuals travel across the borough.

With population expected to reach 400,000 by 2020 Barnet is now London’s most populous borough. The growth in Barnet’s population will change our existing communities, attracting a younger and more diverse population, in addition to this, the increase in population will have a significant impact on the way people travel, which is why Barnet is planning to implement a strategy to manage this and make journeys for these people easier.

The strategy will outline the Council’s commitment to improving transport options for all of our residents. This will involve considering what our appropriate “mix” of future travel modes should be and how we should be investing in various travel modes in order to arrive at a comprehensive choice of travel options for residents that effectively integrate with one another. It will also provide

a high level blueprint to move forward and meet new and emerging challenges as

well as providing a local application of the Mayor’s Transport Strategy goals.

As part of this strategy an online library has been developed to provide a resource to reinforce decision making and make the strategy more transparent to stake holders.
