Research Highlights

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors

Miguel Andres Figliozzi
Transportation corridors are complex systems. Tradeoffs, particularly in terms of traffic mobility, transit performance, accessibility and pedestrian interactions, are not well understood. When the focus is on motorized vehicle mobility and throughput, high traffic or vehicle speeds are desirable because at high speeds more vehicles can flow per unit of time and roadway section. However, high traffic/vehicles speeds are not desirable for pedestrians who have to cross urban arterials. In parti... Read More

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
