NEXUS DDI | DDI Crossovers and Ramps, Functionalities and Designs

Effective design of a Diverging Diamond Intersection’s (DDI) crossovers and ramps is fundamental to achieve optimized and safe operations. They are interconnected elements which makes the design process complicated and iterative. This webinar walks you through developing crossovers and ramps, their characteristics and impacts that design revisions may have on the DDI’s overall operations.

During this webinar, we will review the following:

  • Crossover functionalities and design concepts
  • Geometric design of on and off ramps
  • Eyebrow and island geometric considerations and safety checks
