Dan, I understand that the trip home often takes longer because there's more congestion in the pm (because there are more non-work trips being made during pm rush hour than during am rush hour). Rob Robert B. Case, PE, PTOE Principal Transportation Engineer Hampton Roads Planning District Commission 723 Woodlake Dr., Chesapeake, Va. 23320 voice:757-420-8300; fax:757-523-4881 rcase(a)hrpdc.org I need to get more information on the Journey to Work questions. Can you help me understand why only the one-way home-to-work trip is asked for? Why not the return trip? Is it correct to double the Census travel times to generalize "the average worker spends 51 minutes a day commuting?" I would appreciate your input. The questions arise because we posted the Census data on our web site. We aggregated the data to our geographies and to a more manageable number of categories. As you can imagine; radio stations, outdoor advertising companies, and their ad agency and advertiser clients are very interested in commuting info. If you are interested, you can see the application at <http://www.arbitron.com/radio_stations/transportation.htm> http://www.arbitron.com/radio_stations/transportation.htm.
