Hello AED20 members and friends,
The November FHWA Talking Traffic Webinar will focus on methods to
estimate vehicle occupancy, which is a topic that I think is of broad
interest to people on our committee. The webinar will be November 19 from
2:00-3:30 Eastern. The invitation and more details on the webinar are
attached if you are interested in attending.
Background:
The transportation community relies on vehicle-based measures to
characterize highway demands. The two most common and widely adopted
standards are the annual average daily traffic (AADT) and the annual
average daily truck traffic (AADTT). While such vehicle-based measurements
provide highly effective assessments for highway planning, construction,
operations, and maintenance, gaps exist in the number of persons traveling
in a vehicle, and the tonnage and dollar values of freight moved on trucks.
On the freight front, efforts such as the truck weigh-in-motion program and
the Vehicle Inventory and Use Survey (VIUS) at the national level have been
providing information to link truck flow data to the tonnage and dollar
values of goods moved. On the passenger travel front, the National
Household Travel Survey (NHTS), along with limited state and local surveys,
offer a glimpse of vehicle occupancy information. Unfortunately, the
current household survey data are not robust enough in deciphering more
disaggregated strata such as time of day, seasonality, geographical area,
and roadway types regarding vehicle occupancy.
The FHWA Office of Highway Policy Information (OHPI) has carried out two
phases of major research and development effort, attempting to derive
vehicle occupancy data without resorting to the traditional survey
approach. In this webinar, the OHPI will present a set of vehicle occupancy
factor estimation methods developed for passenger vehicles, trucks, and
buses. Professionals interested in translating vehicle miles traveled (VMT)
data to person miles traveled (PMT), assessing how occupancy data are
developed for travel
demand modeling and forecasting, and attempting to create new measures for
highway needs analysis, operational efficiency evaluation, and performance
assessment, are encouraged to attend.
Objective:
The objective of this vehicle occupancy estimation webinar is twofold:
Share the advanced data analytics with the community to promote data
innovation,
Gather feedback from the transportation community on potential further
method improvements.
