Postcode Sector to Sector Time & Distance Matrix - Upgrade
Availability: In stock
Updated for 2020 - Urban / Rural Classification added for Scotland
There are approximately 110 million records that give the travel time in minutes and the distance by road in miles from each postcode sector to every other postcode sector in the UK, Isle of Man and Channel Islands. Please note that although Northern Ireland is included the use of ferries, possible routes through the Irish Republic and difficulties with the road network mean these figures are only indicative for the BT Postcode Area. For the 2020 edition we have done additional work on the Irish road network so the number of No Result BT postcode sectors has been reduced.
For example, from a Birmingham to an Aberdeen postcode sector:
|B18 9||AB51 5||418.95||437.613|
indicates that it would take 418 minutes (about 7 hours) for 437 miles.
The distances are calculated using the Ordnance Survey 1:10 000 Scale road network for June 2020, combined with ferry routes and Irish roads from XYZ Maps data. The route should be the fastest which may not be the shortest distance. The assumed speeds are based on and usually slightly less than the legal speed limits for the type of road.
After receiving user feedback we have now set a value of -33 as the No Result value for both Time and Distance. Previously the routing software used a default value of infinity.
The values for Rural / Urban Roads in England, Wales and Scotland and all roads elsewhere are:
|Motorway||60 mph||40 mph|
|Motorway Slip Road||40 mph||25 mph|
|Trunk Dual||60 mph||40 mph|
|Trunk Single||55 mph||30 mph|
|A-road Dual||60 mph||30 mph|
|A-road Single||50 mph||25 mph|
|A Slip Road||35 mph||25 mph|
|B-road Dual||50 mph||25 mph|
|B-road Single||40 mph||25 mph|
|B Slip Road||30 mph||25 mph|
|Minor Road||25 mph||25 mph|
|Local Road||20 mph||20 mph|
|Local Access Road||20 mph||20 mph|
|Other Slip Road||25 mph||25 mph|
|Secondary Access Road||15 mph||15 mph|
|Restricted Local Access Road||15 mph||15 mph|
|Roundabout||20 mph||20 mph|
|Ferry||10 mph||10 mph|
There is no allowance for congestion, differences between urban and rural in Scotland and Ireland, rest breaks, etc as the data was not available. In each case the start / end point is the geographic centroid of the postcode sector (i.e. the middle). From there the software takes a straight line to the nearest road, then follows the road network to the nearest point to the end point, with a straight line for the final section. There is a difference between the time and distance between the centre points of any two postcode sectors and the actual distance and time between full addresses, but this is proportionately smaller the further apart they are. In the case of the above Aberdeen to Birmingham example, there will only be a 1-2% difference between the Sector to Sector time and distance and the actual house to house time and distance. Where addresses are within the same Postcode Sector or adjacent Sectors then the calculated time / distance will be a poor estimate. A calculation from every postcode to every other postcode is not practical as this would give 1.7 million x 1.7 million combinations, so around 3 trillion results!
