Edenvale is a district within San Jose that consists of significant existing residential uses and over 500 acres of vacant but developable land zoned for light industrial/research & development (R&D). The project would entail development of nearly 10 million square feet of R&D use, which would generate in excess of 10,000 trips in each of the AM and PM peak hours.

The Santa Clara County traffic model was used to assist in establishing trip distribution assumptions. AM and PM peak-hour traffic conditions were evaluated for 59 intersections, 60 directional roadway segments, and 16 directional freeway segments. Hexagon identified the transportation improvements that would be needed to support the additional 9.7 millions of development. The recommendations included the full complement of roadway improvements, ranging from construction of a new interchange to signalization of intersections and lengthening of turn pockets. The analysis also included a detailed evaluation of the effectiveness of proposed interchange improvements. This effort employed the traffic simulation software called TRAF-NETSIM to simulate traffic dynamics in the field such as the effects of weaving, vehicle queuing, and vehicle spillback at intersections. Hexagon also developed a mitigation plan for intermediate levels of project development. Implementation of this plan ensures that adequate transportation capacity would accompany each stage of project development.
