NEXUS DDI and AQCESSRAMP – Integrating Compliant Curb Ramps to Diverging Diamond Interchange Design Workflow


NEXUS DDI reduces the need for the manual calculations during a DDI’s geometric design. Users utilize automated functions to design and check safety requirements such as sight lines, truck movement, eyebrow and median checks. NEXUS DDI provides a flexible environment to design pedestrian crossings as well as typical traffic signage plan(s).

AQCESSRAMP is Transoft’s newest software that automates curb ramp designs. It enables users to effectively design several types of ADA compliant curb ramps. The software includes standard curb ramps and curb types from 50 States’ Departments of Transportation, US Federal regulations including Americans with Disabilities Act Accessibility Guidelines (ADAAG), Federal Highway Administration (FHWA) and Public Right-of Way Accessibility Guidelines (PROWAG).

Attend this webinar to:

  • Review the concept for a future DDI implementation
  • Observe NEXUS DDI’s integrated design workflow and how to plan for active transportation network along a DDI
  • Utilize AQCESSRAMP to design curb ramp(s) at pedestrian crossings.
