Multimodal Transportation Planning Curriculum for Urban Planning Programs
Kristine Williams
Integrated multimodal transportation and land use planning is critical to advancing mode choice, public health and safety, and livability objectives. Communities across the U.S. are seeking to redefine their planning process accordingly. In response, university graduate urban planning and engineering programs are beginning to address multimodal planning and sustainable transportation, but most do not yet offer a robust curriculum on these topics. To help address this need, the University of…

NCHRP 15-73 Design Options to Reduce Turning Motor Vehicle – Bicycle Conflicts at Controlled Intersections
Christopher Monsere Sirisha Kothuri , Nathan McNeil
BACKGROUND
One of the most common locations for fatal motor vehicle-bicyclist crashes is at intersections, which inherently have a large number of turning conflicts. Reducing these conflicts is a key objective in improving intersection safety across all modes. Of particular concern for bicyclists’ safety at intersections are the conflicts between straight-through bicyclists and motor vehicle right-turns and opposing left-turns. Despite the widespread acknowledgement of this problem,…
