Key point
Key point
• A holistic discussion of fuel choices should involve ripple effects on/from behavior
E.g. Electric autonomous vehicles imply(?) lighter vehicles, shorter headways, safer traffic
Will there be a behavior shift? To where?
What about the impacts on the grid?
…and there are many other changes happening
• New emergent (sharing) modes optimize capacity
• Better predictions decrease travel time
• Smoother traffic control decreases congestion
• Less human factor (adaptive CC, autonomy, coordination w/ control system) should lead to less fuel consumption...

HITS vs FMS
• HITS captures origins, destinations, and modes
• FMS also captures routes
• In FMS, user activity pattern varies across different days

Modeling and simulation
Driverless cars
No control infrastructure
Same capacity in less space
Pervasive travel information
Different fuel choices
Fully networked vehicles
SimMobility
Difference in travel times?
Congestion levels?
Land use impacts?
Mode shares?
Environmental impact?
Safety impacts? Ripple effects (e.g. to power grid)?

Wrapping up
• Discussions on fuel choices need to consider behavioral response at multiple levels
• Society and environment need both appropriate fuel choices and an optimized transportation system
• Tools and research exist to help study these factors
