An Oregon House Committee reviews a proposal that would allow more Oregon cities to install and enforce bike signals at busy intersections. Representative Jim Weidner is concerned too many signals may lead to more confusion by drivers, not less. But Paul Mather with the Portland Bureau of Transportation says the signals give cyclists better cues and reduce traffic congestion. The bike signals are timed with "no turn on red" lights that help drivers know how to navigate an intersection with heavy bike and car traffic.
