Study Area
Survey Components >Home Interview Survey >Transit On-Board Survey >External Origin - Destination Survey >MnPASS Mode Survey >Special Generator Studies >U of M >MSP Airport >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 >PlanTrans Ply- GPS sub-survey >Moshe Ben-Akiva, Frank Koppelman, Peter Stopher- advisors
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, MnPASS corridors, other smaller populations) >Recruit and retrieval by phone, mail, or web
Home Interview Survey- 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, MnPASS, transit pass/subsidy, work from home, vehicle availability, bicycle availability
Home Interview Survey- Survey Instrument >Diary- Trip Data >24 Hours- 3AM – 3AM >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 >No interaction between household members (other than joint trips) >Stop and Tour allocation fixed among HH members >Preliminary Tour Structure (based on 2000 TBI data) >3 daily tours >1 HBW tour >1 One WB tour >Up to 1 HBNW tour for people with work tour >Up to 3 HBNW tours for non- workers
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
