East Valley at Tri City Mall Photosimulations

Valley Metro, Mesa, Arizona

The Valley Metro light rail transit line was the first rail transit system to be implemented in the City of Phoenix with branch lines serving outlying communities like Mesa and Tempe. The first step was to complete an environmental study.

The proposed East Valley Corridor would follow West Mainstreet through Mesa. The line would run in the street using either a dedicated median or dedicated curb-side configuration. POITRA Visual was selected to provide design visualization services for the study. Visual simulations would be used to help explain the various alternatives to the public.

The two configurations would be illustrated at a single location to allow for easy comparison. Photo-simulation was determined to be the best medium for accurate visual evaluation and for confident presentation to public stakeholders.

POITRA used its existing custom Siemens Duewag 100 LRT model vehicle and applied the Valley Metro color scheme.

POITRA often creates custom transit vehicles at no cost to the project.

POITRA created photo-simulations of the both alternatives on an Engineer provided photograph. The existing laneage and traffic was shifted to match each of the conceptual design plans using traditonal digital painting techniques.

The Siemens Duewag 100 LRT vehicle was the study's prefered vehicle. Modelers at POITRA had previously created a detailed technical model of the SD100 directly from manufacturers specification sheets. The Valley Metro color scheme was applied.

POITRA then created a 3D site model that included the track bed, rails, overhead catenary system and POITRA model Siemens Duewag 100 LRT vehicles. POITRA modelers created poles for the proposed catenary system that incorporated Mesa's existing signature street lighting. The models were camera matched, lighted, rendered and composited with the base photograph to create the final simulation.

The finished photo-simulations were used in Valley Metro's meetings with the City of Mesa and other governmental and public stakeholders. The final images were also used in project environmental documents.end of article
