TBI Purpose > Provide complete picture of travel in the Twin Cities > New facilities and modes built since 2000 > Changes in society > Economic situation and fuel price volatility > Update regional travel models > Air quality conformity/planning > Transportation policy scenario analysis > Forecasts for project development
Study Area
Survey Components > Home Interview Survey > Transit On-Board Survey > Mn. PASS Mode Survey > Special Generator Studies > U of M > MSP Airport > External Origin Destination Survey > Mall of America > Speed Survey
Consultant Team > Cambridge Systematics- lead, model development > AECOM- local management, model development, external station and speed studies > Abt SRBI- Household survey > Dikita Enterprises- Transit on-board survey > Plan. Trans Ply- GPS sub-survey > Moshe Ben-Akiva, Frank Koppelman, Peter Stopheradvisors
Home Interview Survey. Sample Plan > 12, 200 households (400 7 -day GPS sample) > Address-based random sample, stratified by household size and auto ownership > Some oversamples (bicycle travelers, University, Mn. PASS corridors, other smaller populations) > Recruit and retrieval by phone, mail, or web
Home Interview Survey Instrument > Recruit- Household and Person Data > HH Composition > Number of people, age/sex/relationships, student/employment status, income, disability > Housing Data > Housing type, tenure, rent/own, cost > Transportation Data > Typical commute, licensed driver, Mn. PASS, transit pass/subsidy, work from home, vehicle availability, bicycle availability
Home Interview Survey Instrument > Diary- Trip Data > 24 Hours- 3 AM – 3 AM > Location Data > Time of arrival/departure, address, activity > Trip Data > Type of transportation > Amount paid (parking cost, toll, transit fare) and how it was paid (subsidized parking, monthly payment for parking/transit) > Mode, accompanying travelers
Home Interview Survey. Schedule > Pre-test (internal) > September 2010 > Pilot Survey (~1000 households) > November 2010 -February 2011 > Full Survey (~11, 000 households) > March 2011 -June 2011
Transit On-Board Survey- Survey Instrument > Boarding/alighting and origin/destination > Mode of access > Trip Purpose, auto availability, age, household size, income > Available in English, Spanish, Hmong, Somali > GPS barcode for validation, short trips > Mailback option
Transit On-Board Survey. Sample Plan > Partial survey, focusing on Northstar, Hiawatha, current and potential New Starts and Arterial BRT corridors > Proportional sample > Targeting 108 routes, representing 80% of daily ridership > 10, 000 -15, 000 completed surveys > Combine with 2005 survey data
Transit On-Board Survey. Schedule > Pre-test in Aug/Sept 2010 > Survey began on Sept 27, 2010 > End date Nov 19, 2010
Regional Model Development- Policy Issues > Highway >Operations, ramp metering, HOV lanes, bus shoulders, peak spreading, pricing, managed lanes, minor arterials/collectors > Transit >Operations, pricing, BRT, impact of parking policies/pricing
Regional Model Development- Tour-based model > Simplifying assumptions: > No linkages between tours > Preliminary Tour Structure (based on 2000 TBI data) > No interaction between household members (other than joint trips) > 3 daily tours > Stop and Tour allocation fixed among HH members > 1 One WB tour > 1 HBW tour > Up to 1 HBNW tour for people with work tour > Up to 3 HBNW tours for nonworkers
Regional Model Development- Policy Issues > Validation and Application to lower-level facilities (minor arterials, BRT) > New TAZ system (2600 zones in 7 -county area) > New networks > Lower level, conflated, and consistent
