QUOTE The problem was originally described by industrial engineer John
Forester in his 800-page book Effective Cycling, which boasted seven
editions (MIT Press, 2012).

Forester estimated that accidents on bike lanes are 2.6 times higher than
on roadways, because bike paths are more dangerous. He forecast more
car-bike collisions, because it is difficult to make intersections between
cycle lanes and roads as safe as normal roads. Almost 90 percent of urban
accidents were caused by crossing or turning—either by the cyclist failing
to obey the rules of the road or the motorist turning into the cyclist, as
happened in the case of Langenkamp.

Writing about California plans for bike lanes, Forester stated, “Nobody
with traffic-engineering training could believe that [bikeway] designs that
so contradicted normal traffic-engineering knowledge would produce safe
traffic movements.... If these designs had been proposed for some class of
motorized traffic—say, trucks or motorcycles—the designers would have been
considered crazy.”ENDQUOTE

QUOTE Jan Heine, editor-in-chief of Bicycle Quarterly, wrote, “Any barrier
that separates the cyclist visually from other traffic effectively hides
the cyclist. This is counterproductive to safety. Moving cyclists out of
the roadway altogether, on separate bike paths, is even more dangerous,
because drivers don’t look for (or cannot see) cyclists off to the side.”
He continued, “On streets with frequent intersections, separate paths only
make cycling less safe. I wish those who advocate for them would look at
the data and stop asking for facilities that will cause more
accidents.”ENDQUOTE
