How do you determine which journeys are charged via Zone 1 irrespective of the route taken?

Request ID: FOI-1081-1819
Date published: 13 August 2018

You asked

Following up previous FOI request TfL Ref: 0815-1819 I was previously told that: -- Some journeys are always charged via Zone One for one of the following reasons: The route avoiding Zone One would be unreasonably circuitous. Limitations of the pay as you go system mean that we cannot detect that the journey has definitely avoided Zone One. The journey is deemed to more likely have been made via Zone One. -- My followup questions are: i) For the journey High Barnet to Wandsworth Road, which of those reasons apply? ii) What guidelines or methodology do you use to help decide whether a journey is unreasonably circuitous or not? iii) Is there any way that a traveller can predict a fare for a journey without using the Single Fare finder? iv) Are unreasonably circuitous routes reviewed/changed over time?

Thank you for your email received by us on 19 July 2018 asking for information about pay as you go travel in relation to your previous request (reference: 0815-1819).

My followup questions are:

i) For the journey High Barnet to Wandsworth Road, which of those reasons apply?

I can advise that High Barnet to Wandsworth Road is a journey where limitations of the pay as you go system mean that we cannot detect that the journey has definitely avoided Zone One and the journey is more likely to have been made via Zone One.

ii) What guidelines or methodology do you use to help decide whether a journey is unreasonably circuitous or not?

We take into account journey times, service frequency, ease of interchange, number of changes and customer feedback.

iii) Is there any way that a traveller can predict a fare for a journey without using the Single Fare finder?

The complexity of the various fare scales and possible routes means that for many journeys the Single Fare Finder is the only reliable way to determine the fare charged.

iv) Are unreasonably circuitous routes reviewed/changed over time

Unreasonably circuitous routes are reviewed and fares may be changed in response to customer feedback and changes to for example, service patterns and station layouts.
