Mid-South Regional Survey/Model Update

First Round of Presentations

• 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

Consultant Team

• 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

Project Management

Easy-to-Follow Documentation

Model Assessment

Where are we? and Where do we need to be? Policies to be Tested; Integration with Air Quality, Land use Roadmap for Data Collection and Model Design

Data Collection

Household Surveys Transit Surveys Freight Surveys Bike/Ped Surveys Optional Surveys GPS, Visitor, External Sample Sizes Targeting Methods Survey Dates Questionnaires Data Cleaning Data Expansion

Model Update

Data-Driven Model Development Calibration and Validation Sensitivity Analysis Scripting and Documentation Staff Training and Reports

• 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

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

Transit Onboard Surveys Program and Design

• Sampling Plans
• Instruments
• Download schedules
• Methodology

Coordinate

• Agency

requirements

• Survey activity
• Recruit, hire, and

train local team

Collect Data

• Organize field

activity

• Supervise with

experienced field personnel

• Improve response

rates

• Non-motorized (Bike/Ped) Survey

» Choice based sample » Counts at key locations » Mine HH & transit

• n 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

Model Update

How Do All the Pieces Fit into the Model?

Model Consultation

• Drives survey effort
• Informs model

framework

Household Survey

• Travel repository
• Model estimation
• Model calibration

Bike/Ped Data

• Route preferences
• Counts
• Nonmotorized model

validation

Freight Data

• GPS data
• FAF analysis
• Integrate with

passenger model

Transit On-board Survey

• Enriched sample
• Transit calibration
• Model validation
• Transit operations

• 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
