A Traffic Impact Analysis (TIA) study is a formal engineering evaluation of the likely consequences of a development with respect to transportation issues. For example, if a proposed commercial shopping district is expected to increase the number of vehicles at a nearby intersection, "traffic impact" is the term to describe the result. The level and severity of this "traffic impact" is predicted by engineering review and analysis. At the conclusion of the TIA study, suggestions for physical and operational improvements are made. In addition, a determination of the appropriate financial burden to be borne by the developer is made.
According to the City of Cedar Park Land Development Code, any development that generates more than 2,000 daily trips will require the submittal of a TIA report. The number of estimated daily trips is calculated using industry reference texts, namely the Institute of Transportation Engineers (ITE) Trip Generation Tables, 6th Edition. If you would like more information about the purposes and/or structure of a TIA, please contact the Engineering and Transportation Department at 512-401-5000.
