Incorporate travel-times and distances into routing applications Each record in this dataset has four fields: From Postcode Sector Name; To Postcode Sector Name; Distance (km) and Time (minutes). Appropriate off-peak speeds have been applied to the road network incorporating a reduced speed in heavily congested urban areas and major intersections within cities.
