That's what's been stated: That bike lanes will make Connecticut Avenue "safer" by slowing down the speed of vehicle traffic substantially. |
Who stated this, and where did they state it? Also, what's the current posted speed limit on Connecticut Avenue, and what's the distribution of actual driver speeds? |
There will be four travel lanes. One of them on each side also will be used by buses that will have to stop to let off and pick up passengers on "bus islands." No doubt they will also be blocked by delivery trucks and and others. The turn lanes will likely just encourage slow Connecticut Avenue traffic to divert into side streets. The plan is poorly thought through. |
To add on to that, https://www.washingtonpost.com/transportation/2023/12/20/dc-reckless-driving-traffic-deaths/ To try and what-about the behavior of cyclists and complain that you will have to slow down when we have this plague on our city makes it really hard to believe anyone that is anti - bikes or bike lanes is concerned about anything other than their own convenience |
You seem to think, if you just post this incorrect assertion often enough, it will transform into a correct assertion, but it won't. |
One of the goals of the redesign is to change the "design speed" to more closely match the posted speed (25). Right now you have people driving the design speed+ and others going "merely" 30ish, leading to lots of aggressive lane changes and passing. This is what creates danger, the variability in speed and the "racing to the next stop light" mentality. By reducing variability in speed, you increase safety, and paradoxically increase throughput of a road by reducing average speed. This should make it easier for emergency vehicles to proceed, as fewer intersections should be blocked (by cars, not bikes). |
So which is it - the turn lanes will improve thruput over the status quo - so why would they cause traffic to divert to the side streets. And the side street argument is so stupid - I live in the neighborhood and there really aren't any side streets that are faster as North-South alternatives. If you've read the actual DDOT reports it predicts improved levels of service at all but one intersection along Connecticut Avenue. The actual trade-off here is parking for bike lanes not vehicle thruput for bike lanes - at least have an honest argument about what is proposed. |
This - I don't recall the average speeds on Connecticut Avenue but in other DDOT traffic studies I've read the average speeds on major mixed use corridors is surprisingly low - usually in the range of 10-12 miles per hour. Sure there are brief open stretches where you can hit or even exceed the speed limit but most of the time you are sitting at a traffic light in a queue of cars so the only benefit to gunning it in the open stretches I guess is you have more time to check your phone sitting at a light. Slowing down cars can actually improve traffic and it definitely reduces accidents and improves air quality if it reduces queuing and again it has no impact on the carrying capacity of a road - that is solely determined by the thru put at intersections which as has been stated hundreds of times now in this thread will be improved along Connecticut Avenue by the addition of turn lanes which will prevent a single turning car from narrowing the road from 2 lanes to 1 which commonly happens now. There is actually a great example of this on Connecticut Avenue just across the line in MD. Since Chevy Chase MD added the two speed cameras on SB Connecticut Ave about 10 years ago magically everyone now drives the speed limit between Bradley and Chevy Chase Circle and guess what happened - traffic is now slowed and spread out as it approaches the circle rather than arriving in a high speed knot of cars and that enables cars to smoothly merge and negotiate the circle rather than everyone slamming on the brakes when they get there because they were going 40 MPH and there is a back-up because everyone arrived together - and guess what - there are rarely any back-ups SB at the circle anymore while they used to be persistent. |
I am copying this post to my notes app so I can reshare the next time one of these debates comes up. So well said. |
Not slow it to a crawl. Look, it is pretty straightforward here. Most drivers do actually follow the speed limit and red light guidance. When a road has 3 or 4 active travel lanes in one direction, those drivers are spread out amongst those lanes. This leaves more opportunity for drivers who don't follow the law to juke around them and drive recklessly by speeding and running red lights. Reducing the number of active travel lanes to two lowers that amount of opportunity. The drivers who obey the laws stand a far better chance of setting the norms for the road usage when there are 2 travel lanes vs. 4 travel lanes. It's that simple. |
There are currently parking lanes and often times double parked cars and trucks. There are also currently buses operating just as you describe. In the new scenario, there are 24/7 parking areas, where those double parked trucks will now be able to load and unload without double parking. The new configuration will also include left turn lanes, which do not exist today. That means that through traffic will be able to continue without getting stacked up in the left lanes. With two clear through lanes, left turn lanes and dedicated parking/loading areas, the order on the Avenue will be significantly improved, not degraded as predicted by the NIMBYs. |
| Will there by left turn lanes at each intersection? Otherwise traffic will be stuck behind a left turning vehicle into an intersecting street. |
Unfortunately, your point is not correct. Woodley, Cleveland Park, North Cleveland Park east-west streets have a lot of through traffic (a good but not complete proxy is the number of MD and VA license plates) that go between Connecticut, Reno, Wisconsin, Massachusetts, looking for the fastest route north and west to MD or VA or south and east to downtown. If Connecticut is constrained this will increase a lot, as will traffic on Reno, Wisconsin, etc. |
But Connecticut will not be constrained. |
