Resources: Open data travel times and distances from all UK LSOA to all acute hospitals

Below are links to travel times from all English Lower Super Output Areas to all English acute hospitals. Please contact me if I have missed any acute hospitals.

The data comes from OpenStreetMap, with travel times and distances calculated using the Routino engine. All data and code is free and open source. Fastest times were used.

Note: 31st March. Travel times for 150 routes (selected at random) were compared with Google maps (clear road conditions; 2am Wednesday morning). Compared to Google Maps, the Open Street Map method under-estimated shorter travel times more than longer travel times. A correction factor was calculated as:

Correction factor = -0.147*ln(OSM_travel_time)+1.872

All travel times are adjusted by this factor in the adjusted travel time data set. This results in a R-square of 0.997 in the training set of data (an independent set of data will be evaluated).
