I was in Baltimore and I noticed several things.
I checked out Potomac Street in Canton, since I had read about a lot of consternation regarding a bike lane that was recently installed on that street. For more information, see:
https://www.bikemore.net/news/potomac-street-victory-lap?rq=potomacFrom my own vantage point, it seems that Potomac is a relatively quiet residential street, for a densely packed city, so it can survive just fine with one lane of traffic. The problem is that the lane, especially between Eastern and Fait, is especially narrow. It seemed a lot narrower than the 11 feet that was in the manual on the above link. It seemed like I had to slow to a crawl to avoid hitting the posts protecting the bike lane or some of the longer cars that were parked at angles.
(IMO, they should've made the bike lanes on both Potomac and Ellwood, but each in only one direction, parallel to automobile traffic. There is enough room on each for one-way protected bike lanes, parallel parking, and a decently wide travel lane. By making Potomac's bike lane two-way, they severly constricted the width of the street, which is why many of the residents are complaining.)
For Downtown Baltimore, I noticed the bike lane along Maryland/Cathedral/Liberty/Hopkins, which is all one continuous street. Here, the bike lane seemed wide enough, and the lane of traffic seemed wide enough, but the single lane was really busy. It seems that within Downtown Baltimore there are many more lanes for northbound traffic than southbound traffic. It seems this mismatch has been in place along time with Howard and Park Ave being northbound, but it is exacerbated by the fact that a southbound lane was removed from Maryland/Cathedral.
Much of Downtown Baltimore has the pay and display parking meters. These seem to work great. They take credit cards and you can pay for the time you need and display the receipt on your dashboard. It seemed that different parts of Downtown were charged at different rates: $1.75/hr , $2/hr, or $2.25/hr. What is also nice is that they alert you as to when you cannot park and won't accept payment when parking is prohibited. It also seemed that a lot of Downtown allowed you to park for up to 4 hours.
There were also reserved meters for the handicapped. While I beleive that the handicapped should not get free parking, I find it unusual that they reserve special spots for them on city streets, from my experience this is only done in parking lots and garages. IT significantly limited the number of available parking spaces.
It would''ve been better to make the pay and dispaly meters fully accessible to all.
Lombard, Pratt, Baltimore, and Fayette now have bus lanes through Downtown. These seemed to be working well and I did not notice any significant backup as I was driving down those streets.
Fell's Point is now extremely crowded. They should make Eastern and Fleet into one-way pairs so that traffic can move along.
