| | Abstract:Behavioural effects of slippery road variable message signs in Turku road district in winter 1993-1994 (Site not responding. Last check: 2007-10-08) |
 | | The recommendation was assigned to each vehicle and its value depended on vehicle type, speed, and the prevailing road surface condition class. |
 | | The signs were studied at Eurajoki (highway 8), Kullaa (11) and Koski TL (10). |
 | | The proportion of headways below 1.5 seconds remained unchanged at Kullaa and Koski TL, where there were no headway VMS signs. |
