Civil and Environmental Engineering Thesis Defense: Carl Olson
Monday, October 29, 2012 - 2:30pm

The Department of Civil and Environmental Engineering is pleased to announce Carl Olson's MS Thesis Defense: "Safety Effectiveness of Red Light Treatments for Red Light Running."

Date: Monday, October 29, 2012
Time: 2:30pm
Location: Engineering Building 315
Adviser: Dr. Christopher Monsere

Crashes due to red light running are typically severe in nature. In Portland, Oregon, eight intersections received a variety of treatments including red extensions. These red extensions have the ability to increase the red clearance interval if a vehicle enters the intersection late. By using a combination of before and after crash analysis and a  model simulating an intersection with red extensions, the impact of the intersection upgrades with regard to crashes was estimated.
