26,000 households will be allocated among 50 states and DC area, in particular the counties within a state, according to the proportion of the national population Counties containing Metropolitan Statistical Areas (MSAs) Counties MSAs>1 M people & Heavy rail Counties MSAs>1 M people & no heavy rail Counties MSAs<1M people Counties containing no MSAs 9
10
If a state is allocated less than 250 households, the state sample size will be increased to 250 households Once a minimum of 250 households is assigned to each state, the remaining households will be allocated among the larger states in proportion with the state populations 10
11
423 households would be allocated to the state of Wisconsin, based on the number of households in the state compared to all households in the nation 11
12
States and MPOs have the unique opportunity to purchase samples These additional samples, along with random national samples collected in the add-on area. Trips of ALL lengths, for ALL purposes, and for ALL modes are collected. 6 questions in 2015 12

DOTs: Arizona, California, Georgia, Maryland, New York, North Carolina, South Carolina, Texas, Wisconsin MPOs: Des Moines (IA), Indian Nations (OK), Iowa Northland (IA), North Central Texas COG, 13

Deliverables: Edited, weighted data, O-D geocodes for all trip purposes and modes, Odometer readings, transit, walk, bike trips, documentation and user’s guide, web-based retrieval system Benefits: On demand, consistent local and national data, no contracting or oversight hassles, centrally coordinated, high data quality/low risk, economies of scale 14

Used it to adjust home based shopping and non home based trip rates for the development of travel demand model the data has been passed on to 8-10 different agencies including FHWA, Oak Ridge National Lab, who have used it for a variety of applications 16
17
11,000 households will be distributed among the eight “travel demand model areas” plus the rest of the state Households are sampled from counties with probability proportional to county size 6/7 of the add on sample will be collected on weekdays, with the remaining 1/7 collected on weekend days Advertisement will be done 17
