I am wondering if it is possible to use iRAP to code only a single site (e.g. an intersection, including 50m on each side to create a 100m segment)? Or does ViDA require multiple sections to be able to generate the analysis (e.g. minimum length of 200m)?  
Thanks  
Phil

Hi Phil.  
Yes, you can generate results to spot locations. I’d suggest using the demonstrator instead of ViDA.

Hello Phil.

It is possible to use Demonstrator to generate star rating details of any segment/section if the road, regardless of its length.

Good luck
