RE: [CTPP] CTPP - Part 3 - summary level question

Bob: You want to know how many workers working in downtown live in specific suburbs. I would go about it in a different way: 1. Select WORKPLACE - IN, the second option. 2. Select all the destination TAZs. 3. Select the general residence area = All workers in the state of MN? 4. Option a. Once the session is created, you can either export the data to an Excel spreadsheet, and then: i. Break the components of geography into the Residence, Work TAZ, and then ii. Query for the specific TAZs in the suburbia on the residence end. OR Option b. i. Click on the mapping engine, then click on the Data Analysis Tool. ii. Using the yellow selection tool, Select all the flows you want to aggregate between the downtown and the specific TAZs. iii. Highlight the tables you want to aggregate, and then click on the spreadsheet view within the Data Analysis Window. The aggregated answer will show-up on the sheet. Part 3 is going to cause some confusion in the minds of any user. Also, please note that tables 3-08 to 3-14 should not be accessed using the browser, use the TranStats website instead. If in doubt, please call/e-mail me.

I have had problems trying to access different summary levels. On the bottom of page 1 of the instructions for working with Part3 it states: "First option button: "From RESIDENCE Geography out" -- click this radial button if you want to know the workplaces for residents in a particular area. For example, if you want to know where workers who live in Suburb A commute. Do they go downtown, or to the largest employer, or do they go all over the region." Since I would like to know how many workers living in specific suburbs actually work downtown, this appeared to be the way to go. HOWEVER, if I select the summary level for the place of residence, I cannot re-select the summary level for place of work. How can I get "downtown" as a work destination, which is at the TAZ level if the only summary level option available is "place"? Apparently I have to identify the TAZ for each place of resident in order to get TAZ of work. Yet I cannot identify TAZs of work - all I get to select is the county of work. So I get all TAZs in the county. Am I doing this incorrectly? Any thoughts?
