[CTPP] Fw: Bureau of Transportation Statistics--TranStats User Testing--Please delete any duplicate submisisons

by Peter J. Foote

Please forgive any duplication - I am sending this as a bcc to a variety of lists in the interest of time - if you get this more than once, please just delete the other notices that originate from me. Please forward this to others that you know of that may find this service of interest. Peter J. Foote PFoote(a)TransitChicago.com Market Research/Resource Planning Planning Division Chicago Transit Authority 120 N. Racine Avenue Chicago, IL 60607 (312) 733-7000 x 6840 (Voice) (312) 432 - 7108 (Fax) ----- Original Message ----- From: "TRANSTATS" <TRANSTATS(a)inet.bts.gov> Sent: Monday, August 19, 2002 4:46 PM Subject: Bureau of Transportation Statistics--TranStats User Testing We'd like your help in testing a new website--TranStats, the intermodal transportation database. TranStats is a new website (http://www.bts.gov/transtats) for transportation researchers and analysts aimed at providing "one-stop shopping" for transportation data. The premise is fairly simple: By reducing the time needed to gather data, more time is made available for analysis. And easy linkages across many data sets can provide new insights. Ultimately, this should result in more timely and more informed decisions, and a better transportation system. Until now, the process of compiling data to analyze a transportation problem commonly involved searching for data sources, contacting various data providers to get the data--often many times, sorting through the data, and integrating data from various sources for analysis. This is a very labor-intensive process, often taking months. TranStats is an e-government initiative aimed at streamlining this process. TranStats offers analysts several unique features: · A searchable index of over 100 transportation-related databases across every mode of transportation, along with many social, economic and demographic data sets commonly used in transportation analysis. · Selective download--the ability to choose variables of interest and download the data directly to your PC for analysis using any database, spreadsheet, or statistical package. · Online data documentation--summary information about each database, data definitions, and code information for data variables. · Interactive analytical tools--the ability to perform simple statistical summaries, create time series or cross tabulations, generate graphics online, and cut/paste results into reports. · Interactive mapping to help visualize geographic data. · A mapping center with the full National Transportation Atlas Database, as well as applications for easily mapping several other key data sets. Users can explore data by transportation mode, agency or by subject area, use keyword searches to find relevant datasets, and get online help. And because all the data in TranStats are indexed with a transportation thesaurus, links to other transportation research information and data are easy through the National Transportation Library. The website is at http://www.bts.gov/transtats. Check out "Getting Started" on the TranStats homepage. Your comments and feedback will help us ensure high standards of quality and usability before we release TranStats to the public. For example, we want to know if the site is user friendly. Are databases easy to access? Are database descriptions adequate? Are the analytical tools useful? Is the site easy to navigate? Is the design intuitive? Please explore TranStats and send us your comments and feedback through e-mail (answers(a)bts.gov) or call us toll-free (1-800-853-1351). If you have trouble starting up and need help, please send us an e-mail at the same address or call the same toll-free number--our information service specialists will be there to answer your questions. The user testing will continue through COB Friday, August 30th, 2002. Please feel free to spread this message to other users who might be interested. We'll appreciate your help in making this a success. Ashish K. Sen Director, Bureau of Transportation Statistics U.S. Department of Transportation Washington, DC.

Re: [CTPP] Has anybody downloaded SF3 by BG??

by Peter H. Van Demark

Kevin: >Now that the Census has released SF3, does the LIST know of way to download >(at once) all of the Block Group SF3 data for a county, or do I have to >download each Tract individually and merge them? The structure of SF 3 is one header file plus 76 (!) data files, none with more that 250 fields, to handle the 16,520 fields in the 405 tables for Census Tracts and above. There are "only" 5558 fields in 281 tables for Block Groups. Each file has all summary levels mixed together, so you have to search each file that has the tables you want to look for the block groups or other areas you want. TransCAD and Maptitude users have it a lot easier. TransCAD users get the SF 3 Data CD for their state free as part of their maintenance agreement, plus the State Data CD with Block Group and other boundaries for their state. Maptitude users (or TransCAD users that want other states) can buy these CDs for $195 each. Nationwide Census Tracts, ZCTAs, counties, MSAs, etc. come with both TransCAD and Maptitude. The SF3 Data CDs have all 77 files merged, then split into each summary level: Block Groups, Census Tracts, etc. With the Table Chooser for SF 3, an add-in to TransCAD and Maptitude, you can easily pick the geography and tables that you want, and output a geographic file (with the tables attached) or just a tabular file. SF 3 Data CDs are being released as the Census Bureau releases the states. 12 states are out, and seven more are due tomorrow.

Re: [CTPP] Has anybody downloaded SF3 by BG??

by Nanda Srinivasan

I used the CB FTP site (http://www2.census.gov/census_2000/datasets/Summary_File_3/) for the data: The SF 3 files are built on the same lines as the previous releases (SF 1 and PL data). The package consists of one GEOGRAPHIC file, and 76 data files. The process I used to convert the data into a GIS (in my case Arcview) is: 1. Downloaded the shape file for BGs from the ESRI website at www.geographynetwork.com 2. Downloaded the geography file, and the datafiles from the Census Bureau FTP site at: http://www2.census.gov/census_2000/datasets/Summary_File_3/ 3. Opened these files in MS Access. If you want detailed instructions, please refer to http://www2.census.gov/census_2000/datasets/Summary_File_3/0README_SF3.doc OR http://www.census.gov/support/SF3ASCII.html There is also a specific website to help you open the data in MS Access. Please refer to: http://www.census.gov/support/2000/SF3/ 4. Exported the database into DBF, and connected to the Arcview shapefile downloaded in step 1. Steps 2, and 3 are the only "problem" areas to most users. The Census Bureau is providing LIVE online support, and telephonic support to accomplish these steps. For online support, please visit: http://www.census.gov/support/SF3ASCII.html and click on the GREEN BOX with the title "LIVE HELP". The telephonic and e-mail contact information is: 301-457-1324 Voice 301-457-1296 Fax TechSupp(a)Census.gov If you need more help on the Arcview/GIS side (steps 1, and 4), please refer to the FHWA Census Issues website note on SF 1 data. http://www.fhwa.dot.gov/planning/census/sf1.htm The steps are almost the same, the difference is that in the case of SF1, the data was at the level of census blocks, most of SF 3 data is at the level of Block Groups. Hope the above is of use!

[CTPP] FHWA Urban Area boundaries

by SRTC GIS

Does anyone know when the FHWA will decide on whether it is going to use the Census defined UAB or allow the development of modified ones by MPO's? I comparing Spokane County, WA 2000 Census UAs with our FHWA adopted UAB, there's some quite significant differences, such as the river flowing through the middle of the UA is non-urban, which splits the main UA into two parts (and theoretically makes the bridges across the river subject to rural funding programs instead of urban.) Thanks for any information that develops. Eric Johnson GIS Supervisor Spokane Regional Transportation Council

RE: [CTPP] Adjusted Urbanized Area

by Putta

I have to add one more question to my previous list: should the state consider the population of revised/adjusted urbanized area for STP-UZA allocation? It (the Adjusted UZA) might be strictly for HPMS purpose only as most would suggest. Thank you everyone. I am sending this also to the MPO List - as some MPO experts may shed some more light on the practice. (for those on the MPO list: my original question was to do with: the State with co-operation from the MPOs shall fix urbanized area boundaries (smoothing out is the term used often) - for HPMS or other purposes). Following responses are self-explanatory. Viplav Putta INCOG ---------------------------------------- Nancy: I got the following responses on the issue of smoothing, which may help others (-VP): --------------------------------------------- Glen Ahlert [gahlert(a)swfrpc.org] The only guidance available from FHWA on this dates from 1991, and still contains a number of obsolete references. It will also leave a lot of your questions unanswered, I suspect. You can download it at http://www.fhwa.dot.gov//////legsregs/directives/fapg/g406300.htm. You might also want to talk to Bob Diogo (bdiogo(a)swfrpc.org) in this office, who has been trying to develop smoothed urbanized area and urban cluster boundaries for this area, about what he has learned and how he's gone about it. ----------------------------------------------- John Coil [jcoil(a)drcog.org] The FHWA requirement for smoothing urbanized areas (or creating transportation urban areas) was focused as an MPO function in 1975, 1983 and 1992. The MPOs needed to define the transportation urban areas and then the urban and rural functional classification to determine which roads were eligible for federal-aid secondary (rural) and federal-aid urban (urban) funding based on the 1974 Federal-aid Highway Act. The MPOs paid little attention to the HPMS data reporting requirements. With the advent of ISTEA in 1992, the need for transportation urban areas declined to just billboard locations, HPMS data reporting and speed limit controls. Since, the Census urbanized boundary now controls billboard locations and the speed controls have been removed. The only remaining need for transportation urban area definitions is the HPMS data reporting requirement. BUT, I think FHWA and many MPOs would like to have a consistent set of transportation urban areas for mapping and other planning functions. I do not know about the MPO interests in Oklahoma, but Denver MPO has no real interest in the urbanized/ transportation urban data reporting. We need data by the TMA to meet our Congressional transportation planning requirements. The 1990 Clean Air Act and ISTEA changed the geography we use in our planning and air quality conformity process. It is too bad that FHWA did not immediately change the HMPS data reporting requirements to match federal law. ---------------------------------------------------------- Mitchell, Steve R. [Steve.Mitchell(a)ahtd.state.ar.us] Go to the following link (http://www.fhwa.dot.gov/planning/census/faqa2cdt.htm#20 ) for information and contacts on the urbanized area boundary smoothing. It was a very big deal after the 1990 Census and ISTEA because there was a nation-wide functional reclassification of the entire roadway network. Back then there was guidance and workshops to help with the process. The FHWA Division offices (states) are now responsible for assisting the states and the information given out is very fragmented and confusing for everyone, not just those who haven't done it before. The information I have has never given a finite limit to the amount of adjustment...just that everyone involved must agree that it is reasonable. The smoothing affects what is classified as urban and rural by the State and Federal government which affects many things they do and could affect funding. The smoothing may be done for all areas classified as urban, not just urbanized areas above 200,000 population. The smoothing is supposed to be done in cooperation with the MPO in large areas. Make suggestions to your DOT as you think appropriate to make data management easier -----------------------------------------------------
