Effects Of The Energy Crisis On Traffic In Kentucky, Kenneth R. Agent, Donald R. Herd, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

The Arab oil embargo in mid-October 1973 curtailed availability of gasoline. Fuel conservation measures resulted in reduced travel and decreased traffic speeds. On March 1, 1974, posted speed was set at 55 mph on rural highways in Kentucky. Traffic volumes, speeds, and accidents for the rural highway during the period known as the "energy crisis" and its after effects were compared to the corresponding period a year earlier.

Traffic volumes began to decline in December 1973 but began to rise again in March 1974. Total travel in the seven months through June 1974 decreased by 3.5 percent; traffic increased by …

Bridge Decks Constructed For Increased Durability, Assaf S. Rahal

Kentucky Transportation Center Research Report

The experimental features incorporated in this study were compaction, brooming, and hi-layered construction. Broomed surfaces initially exhibited a higher skidding resistance than non-broomed surfaces: broomed surfaces, however, wear more rapidly. No conclusive evaluation could be made at this time of the bilayered system and of tests made on the concrete cores. Electrical measurements made on the decks indicated there was no active corrosion of the steel.
