I have been very active in design and delivery of several Americans with Disabilities Act (ADA) projects lately. This recent experience with sidewalks, cross walks, and pedestrian actuators will allow me to teach and opinion on the accident particulars quickly.
I've worked in construction, and have evaluated road grading and construction projects for completeness and whether standards were met. I've calculated estimates for such projects ranging from back of the envelope estimates through very detailed ones.
I have done several vehicle vs. bus stop accidents In Las Vegas, Nevada and the surrounding small cities around Las Vegas. I am familiar with bus stop layout and location in more urban and more rural areas. Information about these bus stop cases can also be seen in my CD.
I've worked slip and fall cases before, and they have involved: depressions or elevation changes due to asphalt decay. In these cases, I've worked for both plaintiffs and defendants so the arguments of both sides are well known to me. I'm also familiar with pavement studies from my consulting and my Maintenance Engineering experiences.
