Intersection signal timing and carbon monoxide

Research output: Contribution to conferencePaperpeer-review


A comparison is made between changes in signal timing over a period of about two years, and the levels of carbon monoxide detected at a nearby sampler, for a pretimed signalized intersection on the major east-west arterial street in Omaha, Nebraska. The focus of the paper is to determine the utility of non-purpose collected data for evaluating signal timing changes. A literature search is made comparing the results of research into carbon monoxide generation. The sampling data are analyzed and a statistical comparison is made between the carbon monoxide data and the volume to capacity ratios for the different signal timing plans. The results indicate that non-purpose collected data cannot generally be used to evaluate the effects of such changes.
