Traffic Impact Studies

Navigating the development process and reviewing traffic impact studies is a challenge for communities. City staff and developers often have different expectations about what area should be studied and what traffic conditions are considered acceptable. These differing expectations often occur because communities do not have clearly defined impact study policies. The OTO has developed model guidelines for a tiered approach to traffic impact studies. These guidelines include clear standards and expectations, for both the city and the developer.

Below you will find the policy memo, support materials, and example reports. These materials should help communities implement improved, more efficient, traffic impact study policies.

Supporting Materials

To assist communities with implementation, we have developed two supporting documents. The first is a flow chart to visually outline the steps involved in this tiered process. The second is a submittal checklist communities can provide to applicants. This checklist will help reduce the number of submittal revisions.
