From 1975 until 1984, the average annual travel-per-vehicle changed very little except for minor decreases related to economic conditions. This stable annual travel-per-vehicle, coupled with progressively improving fuel efficiency of the U.S. vehicle fleet, resulted in significantly lower annual fuel usage for the average vehicle during this time period.
The post-1984 period showed steady increases in the average vehicle travel each year; in the same period, average total fuel use per year for the average vehicle changed only slightly. In fact, over the last 20 years, the average annual travel has increased by 19.6%, while the associated fuel usage has declined by 3.2%.

(1) improving the accuracy of the data used in travel demand modeling, and (2) reducing respondent burden for reporting trips. If the results show the new approach is effective, it will be tested in one metropolitan area.
This project was designed in three phases. Phases 1 and 2, which examine the hardware and software requirements and develop potential config-urations to meet those requirements, are expected to be completed by January 1996. Phase 3, where actual travel is measured and compared to self-reported travel, is the field test.

In 1970, highway travel was estimated at 1,110 billion vehicle-miles, and has increased yearly except for 1974, 1979, and 1980 (see chart entitled "Highway Travel in the United States"). At the same time, the 1994 increase is up from the 5-year period average annual compounded rate of 2.4 per-cent. The 10- and 20-year growth rates are 3.2 percent and 3.1 percent, respectively.
The share of highway travel in urban areas (5,000 or more persons) continues to increase as a proportion of total travel (51.4 % in 1970 to 61.4% in 1994). This growth is due to an increase in travel by vehicle and in number of places that are defined as urban.

The data that are now arriving will be compared to similar data from the 1990 survey. Initial tabula-tions indicate that patterns in vehicle ownership may be relatively steady with the number of vehicles per household and per driver about the same as in 1990. Also, person-miles traveled per person may be up somewhat for most age groups. These trends, as well as others, will be further investigated as all of the pretest data becomes available.
Included in the pretest were approximately 50 customer service questions that were designed to elicit the views of the respondents on a number of transportation services, such as evaluation of road-way condition, transit, safety of various systems, and reasons for preferring a particular mode. Be-cause of survey length considerations, most of these questions were eliminated from the full NPTS. A complete evaluation of these questions will be undertaken, including how views of respondents may be related to patterns of trip-making.
The NPTS pretest consisted of a national, randomly selected sampling of 4,600 persons in 2,500 households. The NPTS pretest was conducted from November 1994 through January 1995. The full survey began in May 1995 and will continue for a year. Research Triangle Institute in North Carolina is conducting all phases of the survey. As the full NPTS progresses, we plan to provide travel trend analysis on the data as it becomes available.

Subject: The Transportation Research Board (TRB) Conference on Decennial Census Data for Transpor-tation Planning will address data needs for improved transportation planning, policy, and administration using Census data. During the conference, participants will review and evaluate their use of 1990 Census and Census Transportation Planning Package (CTPP) data products. It is not expected that the Census Bureau, under congressional direction, will have decided by the conference date on whether or not there will a "sample" form (traditionally called the "long form") as part of the year 2000 census. Because of this, the conference will address both direc-tions to pursue if journey-to-work questions remain in the census "sample" form and directions to pursue if there is no "sample" form but only a headcount in the decennial census.
Under the assumptions that a "sample" form will be included, data product priorities, delivery schedules, and the role of local governments will be evaluated. Under the assumption that there is no "sample" form, participants will address preferences for other data collection to replace census data.
For more information on this conference, contact Elaine Murakami of FHWA at (202) 366-6971, or Jim Scott or Freda Morgan of TRB at (202) 334-2965. Chuck Purvis of the Metropolitan Transportation Commission is the conference chair. He can be reached at (510) 464-7731 (email: email@example.com).

Subject: The FHWA and the New Mexico State Highway and Transportation Department are presenting the next National Traffic Data Acquisition Conference (NATDAC '96) in Albuquerque, New Mexico, on May 5-9, 1996. The American Association of State Highway Transportation Officials (AASHTO), Institute of Transportation Engineers (ITE), and the Transportation Research Board (TRB) are cosponsors. The conference provides an exciting opportunity to examine and share state-of-the-art technology, knowledge, and progress in the field of traffic data collection and utilization. A comprehensive program will include informative discussions on traffic counting, congestion, vehicle classification, management systems, and weigh-in-motion. There will also be technology demonstrations and workshops on current issues involv-ing traffic data. To receive a registration packet, contact the conference coordinator, Nancy Whalen at (505) 246-6424.
Where: Omni Shoreham Hotel Washington, D.C.
Subject: The 75th annual meeting of the Transportation Research Board will host more than 7,000 transportation planners, researchers, journalists, educators, and others to discuss and exchange transportation research findings and information. There will be approximately 250 sessions covering all aspects of transportation research, planning, and practice.
