Lexington Station Phase 3 Traffic Study February 26, 2021 <br /> Page 3 <br />Note that data collection efforts were conducted during the COVID-19 pandemic and traffic volumes <br />were estimated to be approximately 20 to 30 percent lower than normal conditions for the study area. <br />Therefore, the newly collected turning movements were adjusted to reflect non-COVID conditions <br />by using a combination of recently collected ADT volumes in the study area between 2016 and 2019 <br />and turning movement counts collected/developed as part of the Lexington Station Traffic Study <br />completed by SRF in May 2013. <br />Roadway Characteristics <br />A field assessment was completed to identify various roadway characteristics within the transportation <br />system study area, such as functional classification, general configuration, and posted speed limit. A <br />summary of these roadway characteristics is shown in Table 1. Note that these are general <br />characteristics and that there are some deviations within portions of roadway segments. For example, <br />Red Fox Road is a two-lane undivided roadway that transitions into a three-lane undivided roadway <br />with a continuous center two-way left-turn lane east of Lexington Avenue. <br />Table 1. Existing Roadway Characteristics <br />(1) Functional Classification based on MnDOT’s Functional Classification GIS. <br />(2) Red Fox Road transitions from a two-lane undivided roadway to a 3-lane undivided roadway with a continuous center two-way left-turn <br />lane east of Lexington Avenue. <br />From a traffic control perspective, the Lexington Avenue/Red Fox Road and Lexington <br />Avenue/Grey Fox Road intersections are signalized, while the five other study intersections are <br />unsignalized with side-street stop control. Existing geometrics, traffic controls, and traffic volumes in <br />the study area are shown in Figure 2. <br />Intersection Operations Analysis <br />An operations analysis was conducted to determine how traffic is currently operating at the study <br />intersections. All intersections were analyzed using Synchro/SimTraffic software. Capacity analysis <br />results identify a Level of Service (LOS) which indicates how well an intersection is operating. <br />Intersections are ranked from LOS A through LOS F. The LOS results are based on average delay <br />per vehicle results from SimTraffic, which correspond to the delay threshold values shown in <br />Table 2. LOS A indicates the best traffic operation and LOS F indicates an intersection where demand <br />exceeds capacity. Overall intersection LOS A through D is generally considered acceptable by drivers <br />in the Twin Cities Metropolitan Area. <br />Roadway Functional <br />Classification (1) General Configuration Posted Speed Limit <br />(mph) <br />Lexington Avenue Minor Arterial 5-lane undivided 40 <br />Red Fox Road Local Road 2-lane undivided/3-lane undivided (2) 30 <br />Target Road Local Road 2-lane divided/2-lane undivided N/A <br />Grey Fox Road Local Road 2-lane undivided 30
