In our fast-growing Southwest Washington and Portland metro region, traffic conditions are constantly changing. HDJ’s traffic engineers meticulously track these changes on behalf of our clients. We invite you to join the list of businesses and developers who are making informed decisions about site selection and are receiving superior support from HDJ’s Traffic Engineering Section.

City of Vancouver records that HDJ has performed 30 percent more local traffic studies than it’s nearest competitor. Our traffic team may have already collected traffic counts that can apply to your project. The knowledge and expertise of our traffic engineers can help get your project off to a good start.

HDJ’s traffic development services are cost effective and efficient. Our team conducts detailed studies of the potential impacts of new development on roadway infrastructure, including existing traffic operations, probable trip generation, traffic counts, level of service (LOS) analysis, capacity calculations and review of accident data. Through years of practice we have streamlined this process, meeting agency requirements while minimizing client costs. In many cases, projects can be completed in three weeks or less – one week to gather traffic data, and two weeks to finish the analysis and study.
