What are planning studies?
Don’t confuse traffic studies with planning studies! (Easier said than done, we know.) Planning studies are conducted after the traffic study in preparation for most major roadway improvement projects. These studies look at the environmental impacts of potential roadway improvements, any issues with the actual rocks or landscape (known as geotechnical issues) in the area, and existing and proposed traffic counts. A planning study also analyzes the actual engineering of the roadway, drainage impacts, potential right of way impacts, and any utility relocation impacts, and allows for comments from local officials.
Typically a planning study includes the purpose and need of the study, public input, creating project alternatives, and evaluating socio-economic impacts and cost-effectiveness. Most of the time, detailed engineering is done during a later phase, once the study is completed and the decision to move forward is made.
