US101 and Holly Street Interchange Photosimulations

City of San Carlos, San Carlos, California

POITRA Visual provided photo-realistic simulation for the US101 and Holly Street Interchange reconstruction project. This redesign addressed capacity issues on Holly Street at peak traffic volume hours. The interchange configuration was also adjusted to help ease congestion.

The design included intricate revisions throughout the interchange to accommodate the widened street, reconfigured interchange ramps and alternative pedestrian overcrossings (POC). The project team chose to illustrate the optional designs on a planner aerial. This is an excellent way to display all of a project's alignment features with equal emphasis and still preserve the already constructed appearance of the illustration. An oblique aerial can minimize background detail.

The Engineer provided the base photograph and layout plans for the entire interchange and local street system. POITRA transferred the design data to the photograph carefully adjusting for the slight perspective.

left quotation markWe create a lot of this kind of aerial simulation for proposed interchanges. They really do convey a massive amount of detailed information quickly in a single image.

Additional simulations taken at ground level really flesh out the design ... the more the better. ”

Traditional digital painting techniques were used to update existing ground features including removing the obsolete ramps as needed to accommodate the new design.

POITRA artists then added the revised interchange ramps, retaining walls, laneage, traffic control, sidewalks, medians, fill slopes and POC Alignment Options.

Many of the off system streets were also affected by design changes and needed to be reflected in the simulation. Great care was taken to ensure that the new lane markings were correctly represented and that they integrated with existing roadways as planned.

The previous bridge and roadway design experience of the POITRA Visual principals played a key role in accurately interpreting the Engineer's design plans and efficiently transforming the information into an accurate illustration.

The final aerial simulations were used as meeting materials for the CalTrans and City of San Carlos design and public involvement process. The image played a major role in communicating the proposed design to project's public stakeholders.end of article
