Identification Of Hazardous Locations On City Streets, Charles V. Zegeer Nov 1975

Identification Of Hazardous Locations On City Streets, Charles V. Zegeer

Kentucky Transportation Center Research Report

The purpose of this study was to develop an effective method for identifying hazardous locations in Kentucky cities (over 2,500 population). Methods used in 45 other states were reviewed. Accident information for 69 of the 97 cities over 2,500 population was used to develop criteria for an identification method.

A Number Method was selected for initial identification of midblocks and intersections on arterial-collector streets and on urban freeways. Rate-Quality Control Methods were included in the form of a critical rate factor computed for each location. A set of critical rate curves was constructed for easy determination of critical locations. A …

First-Year Effects Of The Energy Crisis On Traffic In Kentucky (Rural Highways) [May 1975], 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 (24.6 m/s) 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 and continued through September 1974. Total travel in the 12 months through November 1974 decreased by 2.3 percent; traffic increased by five …
