[CTPP] CTPP Request to State DOTs and MPOs

Note: this message is for staff of State Departments of Transportation and Metropolitan Planning Organizations. Other recipients may disregard and delete this message. Just over a week ago, this office sent email messages to the people on our contact list representing each State Department of Transportation and each metropolitan planning organization. We had spoken on the phone with most of the State DOTs before sending the email, but did not attempt to contact the approximately 340 MPOs. The purpose of the message was to gather information we need to produce Part 1 of CTPP 2000, the place of residence tables. they want us to tabulate in Part 1 for each county in their state. From the MPOs, we need to find out which counties (minor civil divisions in the six New England states) they want us to tabulate in Part 1 as part of their MPO region. We then also need to have the MPOs tell us which detailed level of geography they want us to tabulate in each of the counties making up their area. We would like to point out that we will tabulate at least one level of detailed geography for every county. Therefore an MPO will have access to detailed data even for counties that are not contained in their MPO region. This is a change from the 1990 CTPP, when only counties that were part of an MPO had data tabulated at the tract or TAZ level. We are creating data for the MPO region as a convenience, so you won't have to sum up the individual counties yourself. However, the CTPP Access Tool software will allow you to browse or manipulate data for whatever collection of geography you want. So if you want to add to or subtract from the counties in your MPO region you will be able to do so with the software, and the data for all the counties will be available for your use. Note that this information is for CTPP 2000 Part 1 tables, i.e., data by place of residence. We are not asking about tabulating origin-destination flows in Part 3 of CTPP 2000. We will cross that bridge later. So, if you are in a State DOT and involved with CTPP 2000, you should have received a message about this topic from this office. If not, please call us at 301-763-2454 and ask to talk to Fabian Sanchez, Clara Reschovsky, or Phil Salopek. If you are in an MPO and involved with CTPP 2000 you may also have received a message on this topic from our office. However, some State DOTs are coordinating this activity, so not every MPO was sent an email. We ask any MPOs that have not heard anything about this issue to first contact their State DOT, to see if the State DOT is taking care of it. If the State is not handling it and the MPO has not been contacted by us, it may be because our contact list is out of date. In this case we ask the MPO to call 301-763-2454 and talk with Fabian Sanchez, Clara Reschovsky, or Phil Salopek. Thank You.
