New York City installed a large number of parking protected bicycle lanes over the last decade and many cities are now copying this design. But there is an alternative for a road with shared auto/bike/auto parking: the buffered bicycle lane. The parked cars stay at the curb, then a wide bicycle lane, and then a wide painted buffer. The buffer, bike lane, and auto parking could even be slightly raised from the auto travel lane. I believe that having the parked cars between the bicyclists and the autodrivers creates a visbility problem. Auto drivers have a appearing/disappearing bicyclists in the peripheral. I'd like to prove/disprove whether there is a significant safety difference between the two designs.
