RB’s National Cooperative Highway Research Program (NCHRP) Synthesis 432: Recent Roadway Geometric Design Research for Improved Safety and Operations reviews and summarizes roadway geometric design literature completed and published from 2001 through early 2011, particularly research that identified impacts on safety and operations.

This volume is dedicated to collaborative research across STEM disciplines, the arts and humanities. It includes six sections, framed from a global perspective and exhibits contributions from key experts in the field, emerging scholarly voices, and STEAM practitioners. The added value of STEAM projects in research is highlighted in the first section of this book. Ranging from the spatial, medical and environmental humanities to heritage science, this section discusses the course and paths STEAM projects may evolve to in the near future. The second section features reflective essays by scientists and artists on the development of their research, their professional growth and personal learning experiences that the art/science collaborations have afforded their work and careers. Sections III and IV provides practical guidance and advice on facilitating STEAM teams and describe successful collaborative projects. By presenting the objectives and outcomes of relevant research, the chapters in these sections discuss the various steps taken by different teams to achieve project fruition. Paying particular attention to barriers inhibiting STEAM collaboration, these sections also explore the ways in which research teams were able to work effectively. The fifth section presents a review of policy issues and the potential impacts of STEAM research for administrators, funders and policy makers. In its pursuit for balance and inclusion, the volume concludes with a critical reflection on STEAM that argues a different perspective and will prove food for thought to readers.

Explore the Art and Science of Geometric DesignThe Geometric Design of Roads Handbook covers the design of the visible elements of the road-its horizontal and vertical alignments, the cross-section, intersections, and interchanges. Good practice allows the smooth and safe flow of traffic as well as easy maintenance. Geometric design is covered in d
