did not see their value. In general the meetings on materials and construction methods were more successful than those on road safety and road planning policy. In November 1944 Glanville had discussions with representatives from DSIR the Ministry of War Transport and the Ministry of Transport to determine how research should be carried out in the post war years. The discussions concluded that the RRL should be permitted to carry out experiments on roads in use by the public and to re-establish the Road Research Board (RRB) to raise awareness of the RRL's research. That the discussions were successful, despite previous strained relationships, was partly due to Glanville's good relationship with the MOWT's representative H. R. Lintern, whom he had known from early in his career. Post-war After the war Glanville remained with the RRL and concentrated on research into road safety. The organisation soon adopted a radical new form of study, implementing experiments on live highways. This method resulted in improvements to surfacing materials, road marking paint, and non-skid treatments. The laboratory was significantly enlarged in 1946 and took on a wider remit to investigate road safety and traffic management. Research in this area lead to better tyre materials, zebra crossings, speed limits, and laws regarding the wearing of safety helmets and seat belts. The RRL also investigated headlight dazzle, braking distances and the effects off alcohol on drivers. Glanville required the wider use of zebra crossings in road layouts, which led to an 11% fall in pedestrian fatalities by 1951–2. Glanville correctly predicted a post-war rise in the use of motor transport, though it was an even greater increase than he predicted. There remained conflict between the MOT and DSIR over control of the RRL. Glanville sought to smooth relations with the MOT in the post-war years and instructed his staff that any requests for advice from the MOT should be given top priority. At the same time he made it clear to the MOT that the research direction of the RRL was his responsibility As well as road safety work he also worked in the field of concrete engineering. In 1956 he was a visiting lecturer at Cape Town University. In 1957 he chaired the International Road Safety Research Conference. The RRL under Glanville also investigated the layout of road networks and town planning and the properties of road construction materials and became renowned as the leading
