GIS/CAD ENHANCE TRAFFIC NOISE STUDY

Mitigation of environmental impacts is a primary concern of the Santa Clara County Traffic Authority. In December 1987 the authority adopted the Measure A Mitigation Plan, a plan that established its intent not only to meet state and federal mitigation requirements, but to provide enhanced mitigation within its funding limits. A major Measure A construction project is 18 miles of new freeway in the Route 85/West Valley Corridor. The traffic authority selected Engineering-Science, Inc., to conduct a noise impact study and design sound walls to mitigate future noise impacts from Route 85. This article discusses how Engineering-Science used a geographical information system (GIS) and computer aided drafting (CAD) in conjunction with specially developed software to conduct that noise impact study. Using GIS/CAD increased the study's database accuracy substantially and reduced the time spent correcting errors in the input file. A program to integrate all separate software and directly link GIS and the various models used for transportation and community noise analyses is currently under development.
