Protected bicycle lanes have gained popularity as a safer way to get more people cycling. Earlier research from the Transportation Research and Education Center, TREC, at Portland State University showed that people feel safer in lanes with a physical barrier between bicycle and motor vehicle traffic.
The research hadn’t closely studied the intersections, where the barriers—and the protection they offer—go away. With little research guidance, agencies across the country could face the prospect of using untested approaches or avoiding protected lanes altogether.
TREC, through its National Institute for Transportation and Communities pooled-fund program, is now addressing intersections for protected lanes. The program lets agencies and interested partners invest small amounts to join research with a national impact. For this project, 11 partners each put $5,000 to $50,000 toward the $250,000 cost.
The project will help agencies decide which intersection treatments to use in which cases, and what elements each should include. Toole Design Group will work with the Portland State research team to tailor the results to practitioners.
