Mid-South Regional Survey/Model Update First Round of Presentations • Consultant Team • Project Overview » Model Assessment » Data Collection » Model Update » Schedule • Questions/Discussion 2
Consultant Team • Cambridge Systematics – prime, lead modeling & survey analysis • Dikita – lead transit onboard survey • Abt SRBI – lead household survey • Neel-Schaffer – support on freight and non-motorized surveys 3
Project Overview • Purpose is to conduct travel surveys and use findings to update MPO’s travel model • This study is not an end unto itself but rather it is a means to better planning… » Personal travel choices » Freight focus » Policy relevance » Different perspectives 4
Project Overview (continued) Project Model Data Model Management Assessment Collection Update Schedule and Where are we? Household Surveys Data-Driven Model Budget Transit Surveys Development and Freight Surveys Where do we need to be? Bike/Ped Surveys Quality Assurance Calibration and Plans Validation Optional Surveys Policies to be Tested; GPS, Visitor, External Effective Integration with Air Sensitivity Analysis Communication Quality, Land use Sample Sizes Targeting Engage Regional Scripting and Methods Stakeholders Roadmap for Data Documentation Survey Dates Collection and Model Questionnaires Design Staff Training Data Cleaning Easy-to-Follow and Reports Data Expansion Documentation 5
Model Assessment • Model consultation » State of the current model » Structure model to address anticipated needs in conjunction with observed data • Evaluate ability of model to address local planning issues such as » Aerotropolis/freight focus » I-269 transportation/land use/ economics » Urban sprawl » FTA New Starts 6

Data Collection (continued) Household Travel Surveys • Keys to success » Experienced team partnership » Maximizing response rates » Sample planning for geographic Sample Continuous stratification Management Data Flow » Oversampling of hard to reach populations » Addressing nonresponse Reporting Geocoding » GIS/GPS capabilities for QC and Review 8
Data Collection (continued) Household Travel Surveys – Technology GIS Geocoding Geocoded millions of records for survey projects throughout the U.S. GPS Data Collection (Loggers and Smartphones) Can deploy upwards of 2,000 GPS units per survey GPS Processing Customized algorithms, processes, and reporting for HHTS GPS deployment GIS Web-Based Applications Web-based GIS technology for interactive mapping web sites 9
Data Collection (continued) Transit Onboard Surveys Program Coordinate Collect Data and Design • Organize field • Sampling Plans • Agency activity requirements • Instruments • Supervise with • Survey activity • Download schedules experienced field • Methodology • Recruit, hire, and personnel train local team • Improve response rates 10
Data Collection (continued) Non-Motorized and Freight Surveys • Non-motorized (Bike/Ped) Survey » Choice based sample » Counts at key locations » Mine HH & transit on board surveys • Freight/Truck Surveys » Obtain truck GPS data » Cross reference Federal databases » Conduct gate surveys & counts at major truck generators » Incorporate prior data collection efforts 11
Model Update How Do All the Pieces Fit into the Model? Model Consultation • Drives survey effort • Informs model framework Transit On-board Household Survey Survey • Travel repository • Enriched sample • Model estimation • Transit calibration • Model calibration • Model validation • Transit operations Freight Data Bike/Ped Data • GPS data • Route preferences • FAF analysis • Counts • Integrate with • Nonmotorized model passenger model validation 12
Model Update (continued) Model Design Considerations • Pragmatic yet customized model » Sensitive to local policy & behavior » Utilize existing structure • Focus on key modeling steps » Trip rates – impact of economy & gas prices » Modal shifts – bike/ped and transit • Easy to produce summaries » Vehicle-miles & vehicle-hours traveled » Ridership by time-of-day • Air quality – MOVES interface • Identify performance measures » Freight movement/speeds » Job locations & commute patterns » Transit usage 13
