The location at Silver Creek was representative a median running segment of the line. POITRA modified the Engineer provided photograph simply by removing parked cars from what would become travel lanes in the proposed configuration and restoring the background using traditional digital painting techniques. This provided the base photograph to use for all the simulations.
A fictional BRT vehicle was created by POITRA modelers per the direction of VTA Project Manager. A detailed technical model of VTA's preferred Kinkisharyo LRT vehicle had already been created directly from manufacturers specification sheets. VTA colors and markings were applied as they are on existing vehicles in the VTA fleet.
Modelers at POITRA then created a 3D site model to set the layout for the BRT simulation. This required only 3D median islands and the POITRA model VTA BRT vehicles. The site model of the LRT alternative required rails, concrete track bed, LRT catenary system, median islands and the POITRA model VTA LRT vehicles. These models were camera matched, lighted, rendered and composited with the base photograph to produce each simulation.
POITRA then illustrated the comparative construction stage impacts for the both alternatives. Before founding POITRA Visual, Poitra principals have had actual construction management experience which was of great help in representing construction in progress.
The simulations were used in meetings between VTA and the city, the public and other stakeholders. The simulations also appear in the public EA document.
