This report presents the work on the development of the regulation layer for automated merging. It includes system modeling, control system synthesis, theoretical analysis and real-rime implementation and field test. The essential part is a rather general adaptive merging algorithm. Key words:...

This paper is concerned with development of improvement schemes for road networks under future travel demand uncertainty. Three optimization models, sensitivity-based, scenario-based and min-max, are proposed for determining robust optimal improvement schemes that make system performance...

In this paper we use a case study approach to examine how airport operators are addressing bicycle access to their properties and the motivations and obstacles they face, in light of new policies to integrate bicycles, along with transit and walking, into transportation planning, design and...

This paper examines the effects of residential relocation to Shanghai’s suburbs on job accessibility and commuting, focusing on the influences of proximity to metrorail services and neighborhood environments on commute behavior and choices. The policy implications of the research findings...
