anyway – dense, residential or commercial spaces with a lot of different

potential for a large mode share for bicycle and pedestrian traffic and where
auto traffic is expected to be slow, not on thoroughfares without fronting

think it would be a bad idea to use a shared space design on a street like that

<p class=MsoNormal>Good points, Trevor. Also, if either the jogger or the
motorist (or both) was paying less attention to what was on the other side of
the bike lane stripe because they subconsciously assumed that the stripe would
do what it normally does - keep separated lines of traffic separated - then
they would be paying more attention if the bike lane stripe had not been there,
and perhaps yet another bike lane tragedy (which easily could have involved a
cyclist) could have been avoided.<br>

target="_blank">shared space</a> pioneered by Hans Monderman applies here:<br>
<br>
(more below)<o:p></o:p></p>
<p><b>Shared space</b> is a term used to describe an approach to the design,
management and maintenance of <a

title="Social behavior">behaviour</a> in <a
href="http://en.wikipedia.org/wiki/Traffic" target="_blank" title=Traffic>traffic</a>
is more positively affected by the <a

<h2>The philosophy<o:p></o:p></h2>
<p>Safety, congestion, economic vitality and community severance can be
effectively tackled in streets and other public spaces if they are designed and
managed to allow traffic to be fully integrated with other human activity, not
separated from it. A major characteristic of a street designed to this
philosophy is the absence of traditional road markings, signs, traffic signals
and the distinction between "road" and "<a
href="http://en.wikipedia.org/wiki/Sidewalk" target="_blank" title=Sidewalk>pavement</a>".
User behaviour becomes influenced and controlled by natural human interactions
rather than by artificial regulation.<o:p></o:p></p>
</blockquote>
</div>
<p class=MsoNormal style='margin-bottom:12.0pt'>There is a tradeoff between
traffic throughput and the slower speeds/lesser throughput implied by shared
space, so I'm not a proponent of removing all stripes, signs and pavement
(Wade, to answer your question from a few days ago: I think fog lines and
shoulder stripes have their purpose too - but I'm wary of riding to the right
of them just as I'm wary of riding to the right of a bike lane stripe), but in
the case of bike lane stripes I think bicyclists (and joggers) are much better
off if the outside lane is one big attention-enhancing "shared space"
(a.k.a. Wide Outside Lane, or WOL) rather than the attention-inhibiting
"stripe separated space" (a.k.a. bike lane). The relatively minor
reduction in throughput (caused by motorists perhaps having to slow a bit
because they're being more careful due to the lack of separating stripe) is a
valuable tradeoff, for the increased attention, lower speed differentials and
better safety.<br>
<br>
These tragedies are practically unheard of in shared space WOLs, and are all
too common in bike lanes. I believe this is because everyone (motorists,
bicyclists, peds and joggers) pays more attention in shared space WOLs, and
less attention around bike lanes, and every time yet another person dies in a
bike lane from yet another "inadvertent drift" into an <b>unnoticed</b>
occupant of the bike lane, I am only more convinced that bike lanes cause
create more harm than good for cyclists.<br>

<p class=MsoNormal>In California, at least, the law is that peds must use any
suitable adjacent pedestrian facility. Most joggers would reasonably be
expected to agree with each other that the concrete sidewalk is not suitable
for jogging.<br>
<br>
The jogger was proceeding in the proper direction, facing vehicular traffic. In
California, peds in the bike lane must yield to all vehicular traffic (for
example, cyclists). Being in a bike lane, where the motorist is not allowed to
drive, the ped is forgiven for not yielding to the motorist by getting out of
the roadway.<br>
<br>
I hate the use of the word "veer" in news articles, because mostly it
is used as a synonym for "drifted" when in fact it is a much more
abrupt change of position. However, a ped facing motor traffic should be able
to hop onto the curb before being run over, I'd think, unless the driver
actually did perform an extreme and sudden swerve.<br>
