SCICON, the computer services subsidiary of BP, has abandoned a route planning program based on Department of Transport data as it is inferior to an alternative product.
As a result of the merger of its hitherto separate computer systems consultancy and bureau companies, Scicon is concentrating its future efforts on systems based on data developed by its own experts.
While the DTp data used only 6,000 road junctions and 20,000 links, Scicon's own system, used now for its Scicopath and Minipath programs, uses 14,000 junctions and 45,000 links and includes all motorways, A and B roads, and some unclassified roads in Britain and Northern Ireland.
It determines the cheapest, shortest or quickest route between two points, and costs £10,000.
