Connected and Automated Vehicles (CAVs): Implications for Travel and Infrastructure Provision

Planning for a Connected and Autonomous FutureThe 2017 D-STOP SymposiumNatalia Ruiz Juri, Ph.D.February, 2017

Planning & ModelsDifferent 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

GoodVery bad

Speed

Transportation Planning ProcessHow many people want to travel?Where are they going? (and when)What mode will they use?What routes will they follow? Traffic patterns & conditions
