Multispace meters make performance parking easier
DDOT has installed new multispace parking meters all over downtown, including Connecticut Avenue, Wisconsin Avenue, and the Chinatown area. These meters replace older single-head meters which have been unreliable.
The new meters have some capabilities that will help the District more easily implement performance parking. One of the difficulties with implementing a good performance parking plan is the trouble with collecting good data about parking occupancy, and with having meter prices that make sense at different times of day and days of the week.
With old meters, you might only get the number of quarters collected, if it's logged. The transactions won't be tied to times of day or days of the week. To get the kind of occupancy data you need for performance parking, you have to do manual counts and surveys. This isn't a very efficient use of manpower, which may be one reason why performance parking hasn't taken off yet in many cities.
Additionally, since old meters only allow for one hourly rate, it's difficult or impossible to implement rates that vary by time of day or day of week. It's an all-or-nothing prospect, which is why meters typically run all day and then offer free parking at all other hours, including Saturday and evenings. But there is sometimes too much demand to let the parking go free, but not enough demand to charge daytime rates.
The new meters are capable of collecting and transmitting transaction-level data, down to the amount of parking purchased, time of day, and date of sale. By analyzing this data, DDOT can get a very accurate picture of how crowded various parking meters are and when. For example, I obtained a day's worth of data from a parking meter on 8th Street SE (near M Street SE). The data show a dual peak of demand at lunchtime and at 3pm. This data combined with targeted occupancy surveys would allow DDOT to adjust meter rates to more closely match the demand for parking with the price.

Data from DDOT.
As the performance parking pilot around the ballpark demonstrates, the new meters allow for variable pricing by time of day, for the first hour, or even something as complex as special event pricing.
This combination of data collection and flexible rates allows DDOT to more easily implement performance parking downtown. DDOT should work with the Council and local groups to roll out performance parking slowly and steadily, starting with the most crowded blocks and based on the data reported by the District's investment in multispace meters. DDOT should implement a plan of regular data collection and analysis, with surveys to confirm the calculations. Then, rates and time limits should be adjusted to implement a target occupancy, in order to make parking more convenient and available.

If I get back into programming I'll write something in python. Then I'll request a bunch of data and hopefully have something to share.

I think both jurisdictions are looking into it because they both have pay-by-cell on their future implementation plans.

As to Michael's point, what about having people input their license plate number (and the block of the street if need be)? That solves the marked-spaces problem, but maybe it makes enforcement more difficult.

When I lived in Hamburg and Amsterdam some 30 years ago they already had multi-space meters everywhere and Baltimore's had them for years. Nice DC's soon to catch up to 20th century.
Everywhere I go in downtown still has the old two-headed monsters that take 16 quarters for two hours and often don't work. Yesterday by Judciary Square ( I had a load of files for BZA and Ct. of Appeals) I got one that took my first 5 quarters then reverted to 0 and stayed there for the next quarter. I backed into another space and the meter there took 12 quarters to make it to 1 hour. I was able to back into another space as there are now plenty of open meters since people are sick of fooling with them.

Are you really complaining about walking 10-50 feet to the meeter and back to the car? Did you just say that we should have at-space meters for the convenience of the patron? Isn't it convenient that they get to park on the street? Walking a quarter of a block doesn't seem that big of deal.

It would likely be prohibitive to have individual meters that accept credit cards, individual meters are much more time consuming for the District to collect revenue, set rates, and maintain, etc.
Hopefully pay-by-cell will take off and make paying for parking even more convenient.
