==Context==
In the early 1960s the Ministry of Transport began investigating ways to provide traffic information to drivers, and looked into systems already in use in the US and other foreign countries. Between 1962 and 1964 it started the earliest live trial on the M5 in Worcestershire, installing a series of large electronic signs that were capable of displaying a range of fixed messages, each picked out in lightbulbs or neon strips on the sign's face. The messages included ACCIDENT, FOG, ICE and SLOW.

This file contains the key papers on the development of these signs, the research carried out in other countries and the design work, including the diagrams that were used to construct the roadside signals and details of how signals were sent from a control room to the signs via spare cores on the GPO telephone cables at the side of the motorway. It also contains reports on traffic reactions to the signs from the local police forces.

It is one of the key files in VMS development held at the National Archives. However, despite the catalogue listing's promise of photographs, I don't recall seeing any in the file itself. I'll check this when I get home.
