These capacity thresholds are based on the Highway Capacity Manual and the Twin Cities Regional Travel Demand Model. In roadway planning and design, it is undesirable to either overbuild or underbuild a facility. The goal is to build a facility that effectively and efficiently moves traffic. The design of a roadway should reflect its location. In geneml,people in more urban environments expect to incur some congestion during the peak hours, hence the LOS D/E capacity threshold. In rural environments, LOS C is often used as the basis for roadway planning and design, as people typically have a lower tolerance for traffic congestion. Roseville falls into the urban environment category; therefore, the LOS D/E threshold represents the appropriate design capacity for roadways. At this LOS, traffic is generally expected to experience restricted flow only during the peak travel periods. Dur- ing off-peak periods, traffic flow generally operates at LOS A to LOS C. Table 5.9 lists the level of service categories, approximate volume -to -capacity (v/c) ratios and general descriptions of the traffic operations for each category. The LOS for roadways in Roseville was obtained by comparing the traffic level thresholds with the most recent available daily traffic counts (2006). Figure 5.6 (Existing (2006) Roadway Level of Service) displays the results of the capacity analysis completed for the existing conditions. Operations Analysis In a detailed traffic analysis,an operations level ofservice evaluation is conducted. In this type of analysis, the focus City of Roseville
