[CTPP] Where is the CTPP Program with the CTPP Data Access Software?

by Weinberger

Hi All, An Update. The 2006 - 2008 ACS data have been released by the US Census Bureau (CB) and the CTPP Special Tabulation has been developed and delivered. (for the table list see: http://ctpp.transportation.org/Pages/ACSData.aspx) This data set is the one we (the CTPP Program) are using to develop the first CTPP product based on three year ACS Data. In the next few months, I will try to keep this community apprised of our progress on developing and releasing the data access software for the CTPP based on three year ACS special tabulation that we purchased from CB. We issued an RFP in June of 2009 with proposals due late July. The contract was ultimate awarded to the Beyond 20/20 Citygate team. Work commenced on software development in January 2010. The preliminary software has gone through one round of alpha testing, with beta originally scheduled to be the next round. It was decided after alpha testing that another intermediate round of user testing should occur when the software had greater functionality, but was still in a flexible, malleable state. The project is nearly ready for the next round of user testing, identified as "alpha-prime". The purpose of this round of testing is to highlight the changes so far and to elicit feedback from users. Beyond 20/20 has received and started processing the data from ACS. This data was due to be delivered by 30-Jun, but the final tables were not received until 28-Jul. Sample data was provided by mid-June, so Beyond 20/20 has been able to use this to continue development of the data processing logic and for testing. The data in the first set of delivered tables will be part of the alpha-prime testing. Work on the additional features and customization is nearly complete, with all functionality in the alpha-prime testing, except the export to shape files (currently under development) and the thematic mapping. Work on the Session Editor, the customization that will allow users to select geographies from a map, is still in progress. It is essentially functionally complete, but there are still many issues to be resolved. A significant outstanding issue is how the Part 3 data will be represented both in the Session Editor and in the tables themselves. Based on input from CTPP, it appears that there will need to be data available for Part 3 in which the flows are represented in two dimensions (residence and workplace), but it may also be necessary to have a version with a single dimension for those users who do not need to have them split. The alpha-prime will demonstrate both approaches and the final decision on how to represent the data will be made based on feedback from this testing. The next contracted milestone is delivery of the beta release of the package. There has been a request by CTPP for a new piece of functionality to be added to the solution: export to Geodatabase format. This format contains similar information to SHP files, but is stored in a more up-to-date format in a Microsoft Access database. Beyond 20/20 and Citygate are working on a proposal that will identify the additional cost/time required to add this. I will send another update in a few weeks, if you have any questions, do not hesitate to contact me on or off list. Penelope Weinberger CTPP Program Manager AASHTO 202-624-3556 http://ctpp.transportation.org/Pages/default.aspx <http://ctpp.transportation.org/Pages/default.aspx> <http://www.transportation.org> It's just as bad to not make a plan as to blindly follow the one you already have.

[CTPP] What to do when steps in Standard Error Calculations return Negative Numbers

by Krishnan Viswanathan

Apologies for using this forum but I figured this might be appropriate. I am trying to get the upper and lower bound at the 90% CI around shares of people who live and work in Palm Beach County and who live in PB County but work outside PB county. I am using 1 year ACS data from 2008 and am using table B08007. I am getting a negative number under the square root term and obviously it cannot calculate SE. Anyone has pointers for a workaround or what you did when faced with something like this? I doubt if it can deal with imaginary numbers but if there are any statisticians who can elaborate that would be helpful. I am attaching a screenshot of the error along with the actual XLS file. TIA, Krishnan [image: se_error.jpg] -- Krishnan Viswanathan 1101 High Meadow Dr Tallahassee FL 32311
