Land Use and Transportation Policies for a Sustainable Future with Autonomous Vehicles: Scenario Analysis with Simulations

Liming Wang
Yao-Jan Wu
Even though there are tremendous uncertainties in the timing and evolution path of the Autonomous Vehicles (AV) technology, it may become a likely reality within most MPOs' long-range regional transportation plan horizon of twenty years. Yet a recent survey of largest MPOs in the US indicates only one of them "even mentions driverless, automated, or autonomous vehicles in its most recent RTP" (Guerra, 2016 page 211). One of the uncertainties in assessing the impacts of AV is their direction: ... Read More

Understanding Types of Cyclists Nationally

Jennifer Dill

Transportation professionals who are developing plans and projects that aim to change people’s travel behavior – such as getting more people to bicycle – need to understand the people they are targeting. To do so, planners and researchers have developed typologies of cyclists; however, many of these typologies are based upon surveys of current cyclists and, therefore, are of limited use in planning to attract new people to bicycling for transportation. One exception is the “Four Types of Cycl... Read More
