Samenvatting
A poll was taken in the Southeast construction district to categorize roadwork (except construction) in 1978 concerning the users' need for information. A preliminary category classification is suggested: Limitations in trafficability - (Obstables to traffic flow; the outer borders of the working area; and limitations in capacity in relation to traffic load); Factors that affect how the information is presented- (Type of work; light conditions; sight conditions; speed; and road standard).
