They discussed the study area, data col- lection activities, the highway and transit networks, the general structure of the model, and applications of the model. Volume 2 includes a paper on the topic.1 The fol- lowing points were covered in their presentation. • The New York Best Practice Model (NYBPM) study area includes 28 counties in the three states of New York, New Jersey, and Connecticut. The area encom- passes 9,738 square miles. The population of the area is approximately 20 million and there are 8 million house- holds. There are 3,586 transportation analysis zones. The model analyzes travel patterns by four time periods, eight trip purposes, 10 motorized modes, and four urban types. • Data collection activities supporting the develop- ment of the new model included a household travel sur- vey and obtaining socioeconomic and demographic data. A 24-hour place- based diary was completed for 11,264 households. The diaries were completed by all of the household members. The diary included information on the places visited, the activities at each place, the modes of travel, and the time of travel. • Socioeconomic and demographic data collection efforts focused on land use, population, households, employment, and labor force. Forecasts for each of these items were generated for 5-year periods. • Other data collection efforts included traffic counts for 2,300 screenline locations, origin–destination sur- veys, and travel time observations. An origin–destination survey was conducted at 12 cordon stations in New York State. A total of 50,000 questionnaires were distributed and 6,000 were returned. Travel time data were collected between 5:00 a.m. and 9:00 p.m. on 4,500 roadway seg- ments, with 40,000 travel time observations obtained. • The household travel survey was conducted in 1997 and 1998, as a joint project between the New York Metropolitan Transportation Council (NYMTC) and the New Jersey Transportation Planning Agency. The location- based travel survey included 11,000 house- holds, 28,000 people, and 118,000 trips. • The three- state area includes a large highway net- work. There are 52,794 links in the 28 counties. These links include 4,950 high- level facilities, 26,385 arterials, 1 See Chiao, K.-A., A. Mohseni, and S. Bhowmick.
