Casey’s S&P 500 inclusion, a $3.3 million trade of a single-tenant Panera in Upstate New York, and Yesway’s plan to add 130 stores over five years highlight the importance of disciplined site selection using precise traffic analytics to maximize ROI. Generalized or outdated traffic data can introduce 35 to 70 percent errors, impacting underwriting accuracy. C-Site offers year-round, address-specific traffic measurements updated weekly, including directional AADT, intraday volume, seasonal variation, driver speed distributions, and local versus transit traffic. Peer-reviewed studies show visits increase nonlinearly with accurate traffic data and demographic factors up to 20 miles influence visitation. In constrained expansion capital scenarios, C-Site's feasibility studies reduce false positives through metric-based site ranking and sales projections grounded in accurate traffic data. For rent coverage and credit evaluation, hourly and seasonal traffic profiles evaluate lease support resilience. Operations benefit by aligning staffing and inventory through detailed traffic profiles by hour, day, and month. The methodology recommends using address-true directional traffic metrics, quantifying stop potential via driver speed distributions, modeling visits with broad demographics, and stress testing dayparts and seasonality. This approach enables retailers and investors to treat site selection as an evidence-based system critical to achieving ROI in 2026 and beyond.
