Brief guide to the data

Transport Connectivity Travel Time Data. Representative travel times from each small area of England to selected transport destinations (airports, larger rail stations and major road junctions) which are the outputs of journey time modelling algorithms.

This dataset has been created for the production of new experimental statistics which aim to measure transport connectivity, and is provided to allow users to explore the underlying data.

A brief guide to transport connectivity data 
A brief guide to connectivity travel time data: 
England 
 
 
These files provide a detailed dataset of travel times between small area origins in England and selected 
transport destinations (airports, large rail stations and major road junctions).  For each origin – destination 
pair, a representative travel time is given.    
For airports and stations, times are calculated separately for travel by public transport, and by car.  For 
road junctions, only times by car are calculated.   
For each of the destination types, there are files for different time periods.  For details of how travel times 
are estimated over these periods, please refer to the technical documentation. 
These times are effectively the results of a large number of ‘journey planner’ type queries based on public 
transport times tables, road networks and data on average car speeds.   
Data are available for both the public transport mode (PT) and car mode (HW) for 2011. An update for 2013 
is available for the car mode for the AM peak.  
The data is in a comma delimited ASCII format.  There are a number of individual files available, grouped 
into three zip files.  The individual files are listed below 
Files available 
The files contain one row for each origin-destination combination, where a time could be estimated. In 
some cases the journey time algorithm was unable to estimate a time, usually this is where the journey is 
likely to be over 360 minutes – for 2013 an explicit cut-off at 360 minutes was introduced).

A brief guide to transport connectivity data 
Taxonomy of variables 
 
Variable name 
Description 
Year 
Year to which data relate – this field was added for 2013, not present in 2011 datasets 
LSOA_Code 
Lower Super Output Area (LSOA) code, based on 2001 boundaries for 2011 data, 
based on 2011 boundaries for 2013 data. 
Further details can be found via the ONS Geography Portal 
https://geoportal.statistics.gov.uk/geoportal/catalog/main/home.page  
RepTime 
A representative travel time in minutes between the LSOA and the destination (as 
identified by the UID, below) – the estimated minimum time that can be achieved.  
Please refer to the technical documentation for further details. 
Percentage Services 
A frequency score which measures, for public transport, the percentage of time during 
the given time period that the representative time is actually possible. For journeys by 
car, which do not rely on timetables, this variable is 100% throughout. 
UID 
A unique identifier for the destination as defined by DfT, with: 
 
A1 – A39: Airports 
 
R1 – R491: Road junctions 
 
For stations, the standard National Rail three letter codes are used (e.g. VIC 
for London Victoria)  
Further details are available via the destinations lookup table. 
Near Order 
Order of destinations from the origin in terms of travel time i.e. the nearest destination 
has NearOrder=0, the next nearest is NearOrder=1 and so on.
