Planning for a Connected and
Autonomous Future
The 2017 D-STOP Symposium
Natalia Ruiz Juri, Ph.D.
February, 2017
Planning & Models
• Different types of models
• Goal: Characterize & quantify the impacts of CAVs on traffic
networks
Why modeling?
Transportation systems are complex
Starting Point Intended Outcome Final Outcome
Looking at a single dimension of the problem may be misleading
Good
Very bad
Speed
Transportation Planning Process
• How many people want to travel?
• Where are they going? (and when)
• What mode will they use?
• What routes will they follow?
Traffic patterns & conditions
CAVs in the planning process:
Trip Making Behavior
• Number of trips
– New travelers
• Mode choice
– Ride sourcing (?)
• Destination choice
• Life style choices
– Residential location
– Vehicle ownership:
Adoption of CAVs

CAVs in the planning process:
System Performance
• More effective ITS
• Headway reduction
• No control at intersections
• Transition?
fhwa.dot.gov
Dr. Peter Stone
The University of Texas at Austin
CAVs in the planning process:
Routing Behavior
• Information availability and use
• Path selection criteria
• Routing paradigms
The Path to Modeling CAVs
• Interdisciplinary research
• Community engagement
• Data
Safety Pilot Data: Trip Origins
Safety Pilot Data: Routes for
selected origin-destination pair
Thank You!
