HIGHWAY 10 CORRIDOR STUDY - FINAL REPORT Transportation Operations To quantify current transportation operations, the following data collection and roadway capacity analyses were conducted. Data Collection Typically, data collection for a corridor study would involve collecting the most recent traffic data, including daily traffic volumes and intersection turning movement counts. However, this corridor study is being conducted during the COVID-19 pandemic, which has impacted normal travel patterns. Therefore, to ensure the most accurate data possible, a combination of data sources was reviewed, including: • Automated Traffic Recorder (ATR) Station 352 Data • Historical average daily traffic (ADT) volumes provided by MnDOT • Historical intersection turning movement counts collected for previous area studies • StreetLight data, which includes navigation-GPS data and location -based services (LBS) data This data was used to calibrate the existing conditions and ensure typical (non-COVID-19) conditions are represented. Daily Traffic Volumes Highway 10 is an important corridor within Elk River, transporting up to 34,000 vehicles per day (vpd). Heavy Commercial Average Annual Daily Traffic (HCAADT) volumes along Highway 10 average about 1,400 vpd, which equates to approximately four (4) percent heavy commercial vehicles. There are also several key freight facilities within the study area, shown in Figure 8. Travel Patterns Daily traffic patterns for eastbound traffic show higher use Monday through Friday, while westbound traffic peaks Thursday and Friday. Monthly travel peaks occur in both directions from May through September. This suggests that there is a significant amount of summer weekend "cabin" traffic that utilize the corridor. Figure 9and Figure 10display the daily and monthly travel patterns, respectively, on Highway 10. Three years of data (e.g., 2017 through 2019) was utilized and then averaged, which is shown on the figures. Origin -Destination Analysis An Origin -Destination analysis was completed for the study area utilizing StreetLight' Analytics Data from 2019 to better understand who is currently using the corridor. Based on the data, most users of the Highway 10 corridor originate or are destined to locations outside of the study area (70 to 75 percent). The remaining trips include users that originate or are destinated for locations within the study area (25 to 30 percent). Most westbound motorists originate from Highway 10 east of the study area (67 percent) and have destinations that include Highway 10 west of the study area (38 percent), Highway 169 (30 percent), and Highway 101(22 percent). A summary of the key westbound and eastbound origins and destinations are shown in Figure 11and Figure12, respectively. 1 www.streetlightdata.com Page 1 14
