Affordable Housing Trip Generation Strategies and Rates
Kelly Clifton
Kristina Currans , Susan Handy , Robert Schneider
Assessment and mitigation of transportation impacts based on travel demand is required by state, federal, and local laws in California. Determining trip generation is typically the first step in preparing these transportation impact analyses, and current industry standard practice relies on trip rates published by the Institute of Transportation Engineers (ITE). However, ITE protocols emphasize vehicle trip rates without sensitivity to urban context or socioeconomic characteristics, which can...

Shared Space and Bicyclists
Allison Duncan
Shared space is a traffic calming technique and design concept. The technique is relatively new, and the majority of existing research concerns pedestrians only. This mixed methods study will be international in scope focusing on intersections in England. The goal of this dissertation is to understand how cyclists perceive and travel through shared space intersections by observing cyclists as they traverse selected sites and control sites as well as intercepting and surveying those cyclist...
