Abstract

Since 2008 airlines in the U.S. have systematically reducing the number of flights flown at airports in small and medium-sized metropolitan areas. My previous research found that anywhere from 0.5%-17% of the daily traffic on interstate highways (depending on the location) is due to travelers driving to access a large, hub airport, termed “leaked passengers” (for example, consider a traveler in Harrisburg driving to Philadelphia airport to access an airport with better service and lower fares). Advances in automotive technology may both decrease the marginal cost per mile of driving and depress the value of time a traveler attributes to their airport access time; in short, advances in automation may further shift intercity travel between small/medium sized metro areas to largest metro areas to the auto.    
Description
 I seek to estimate 1) the magnitude of this mode shift, based on different levels and penetration of automated vehicles, 2) the changes in overall intercity transportation safety from the possible shifts to ground transportation, and 3) the changes in network demands, infrastructure needs, and environmental emissions from mode shifts. Through a collaboration with the CHOP Center for Injury Research and Prevention, I am: 1) Collecting data from the Strategic Highway Research Program (SHRP 2) Naturalistic Driving Study to develop distributions of traffic accidents, in frequency and severity, and map these accidents over time and space; 2) Modeling travel behavior – and network loads – on the intercity transportation networks using publicly available Bureau of Transportation Statics Data and models I have previously developed; and 3) Modeling crash frequency and severity on corridors of interest.
Timeline
12/16-2/17 Finalize multimodal models of demand over intercity corridors
2/17-4/17 Operationalize models and estimate changing demands/flows
4/17-5/17 Mine safety data
Strategic Description / RD&T

    
Deployment Plan
Planned 3 peer-reviewed papers on the topic; Gave TEDxPenn talk on this topic on April 1, 2017
Expected Outcomes/Impacts
We expect a full scale dynamic model of intercity transportation demands and flows.
