brilliant idea

flexposts don't protect you from cars. concrete curb don't stop cars either.

What does stop cars is a jersey barrier. NYC has put up jersey barriers on a number of their bike tracks that I saw recently - it feels extremely safe and secure. since this is a temporary situation - why not just lease some JBs for M street in the meantime - or are there some unused JBs just sitting around in the DC metro area??? While they are at it, add some to the cycletrack on 15th street and others....

not a bad idea Lee.

However- perhaps DC could buy JBs that are not so damn ugly and that actually add to the appearance of the streetscape.

JB's with planter tops built into them?

JBs with ornamental scrollwork cast into the concrete ?

Well, if we want to protect vulnerable users from wayward cars, and if curbs are insufficient then we'll need jersey barriers along all sidewalks.

Flexposts and curbs protect you from drivers who are in control of their car - which is the overwhelming majority. JBs seem like a dramatic move to protect users from drivers who've last control of their car on a road with a 25mph speed limit.

Flexposts have the advantage of not restricting pedestrians or cyclists from crossing the bike lane at mid-block. Would you really only want to cross the street at intersections?

Another point about Jersey barriers: they typically take 2ft of width from the street. To build "ornamental scrollwork" into them considerably adds to the cost, and to build "planter tops" into them would further increase the width required (in part because, looking at them from the side, they're shaped like a trapezoid with a narrow top).

Froggie- you sound exactly like a 1960's era Brutalist developer;

"any architectural details adds costs and is not efficient so we must avoid that track"

Of course- peopel have to live with whatever we build. People can only live with institutional architecture and "efficiency" for so long. Good design is critical to overcoming a VERY overlooked problem in the USA- it is called VISUAL POLLUTION.

As for the jaywalking options- which I am totally in favor of- any new JBs could have mid-block breaks to allow for pedestrian access. This is a good point.

As a regular cyclist in DC- Iam a lot more fearful of car /auto drivers than "terrorists" since they are an immediate and palpable threat to me. JBs are the answer for the feds- and they could be the answer for some of the busier auto trafficed streets around here, It is certainly an option- so lets try to not dismiss it out of hand and keep an open mind. We should be trying to make cycling to be regarded as a very safe activity- and to put more different kinds of people on bicycles. This kind of thing might just help to accomplis this goal.

I'm not familiar with this particular section of M Street - not since it's become completely redeveloped beyond all recognition, anyhow - is there something wrong with the sidewalks there?

Many cyclists don't like to ride on the sidewalks.

Chris might have a point here- another way of providing safer auto protected bike ways is to bump out the sidewalk- making an area that is separate from peds and safe from cars. I have seen this in Europe. This is fairly common in both Berlin and in Koln. Of course- in both of these cities the intersections have special traffic lights just for the cyclists. We have not gotten quite to that level here yet.

There are many ways to build safer bikeways.

w: just stating the facts. I don't have an opinion either way in this particular case.

Riding on sidewalks: isn't illegal in that particular region of DC? Even if not, it is a very bad idea for pedestrians and cyclists.

Most people who suggest sidewalks as a viable place to cycle are from the suburbs, where sidewalks are mostly empty. In the city, that just does not work. As a cyclist, it's exasperating; as a pedestrian, it's inharmonious to a leisurely stroll, and sometimes scary.

Those who have seen arrangements in Europe may be confusing sidewalks with cycle tracks. In Copenhagen for instance, there's typically the road, then maybe parked cars, then a cycle track, then sidewalks, all of which are grade separated (curbs). And that's one reason why you see grandmas and little tikes and everyone in between riding there.

SJE, it's legal on M Street SE/SW, but in order to be safe, has to be done at slow speeds. A cycletrack is the best of both worlds.
