Crash History After Installation Of Traffic Signals (Warranted Vs. Unwarranted), Kenneth R. Agent, Eric R. Green Jan 2008

Crash History After Installation Of Traffic Signals (Warranted Vs. Unwarranted), Kenneth R. Agent, Eric R. Green

Kentucky Transportation Center Research Report

The objective of this study was to determine the change in crash history at intersections after installation of a traffic signal. Signals installed based on the warrants from an engineering study resulted in a decrease in angle collisions with an increase in the less severe rear end collisions. At intersections where signal warrants were not met, there was a smaller decrease in angle collisions and a larger increase in rear end collisions. The removal of unwarranted traffic signals did not result in a crash problem. The analysis shows that the warrants given in the MUTCD should be followed when determining …


Use Of Edge Line Markings On Rural Two-Lane Highways, Kenneth R. Agent, Eric R. Green Jan 2008

Use Of Edge Line Markings On Rural Two-Lane Highways, Kenneth R. Agent, Eric R. Green

Kentucky Transportation Center Research Report

The objective of this study was to review roadway characteristics and crash data in Kentucky and determine if revisions should be made to current guidelines for the use of edge lines. Recommendations were made concerning the use of edge lines, centerlines, and paved shoulders on rural, two-lane roadways with varying pavement widths.
