The Year 2010 LOS ratios, assuming no additional roadway improvements other than those that are presently committed, are illustrated in Figure Trans-l0. The ratios reflect the difference between the forecast traffic and the design capacity of the facility at LOS C. The LOS C service volume was used so the City would be able to identify potential traffic concerns prior to the development of severe congestion. Any value greater than 1.00 represents a LOS of D or worse. The deficiencies highlighted by the LOS ratios reflect continued increases in traffic compared with relatively minor increases in capacity from committed projects. Typically, as congestion on any given roadway increases, traffic begins to find alternate routes through neighborhood streets. As a result, deficiencies may not reach as high as indicated but traffic on local streets may become more of a problem. Roadways forecasted to carry volumes that exceed the roadways LOS C design capacity include: 1. I-35W - through City 2. TH 36 - through City 3. TH 280 - through City 4. Snelling Avenue - through City 5. Rice Street - through City 6. Lexington Avenue - Larpenteur Avenue to County Road C2 7. Fairview Avenue - Roselawn Avenue to County Road B, TH 36 to County Road B2, and Terrace Drive to County Road D 8. County Road B - Cleveland Avenue to Fairview Avenue and Dale Street to Rice Street 9. Larpenteur Avenue - Lexington Avenue to Victoria Street 10. County Road D - Old Highway 8 to TH 88 and Cleveland Avenue to Fairview Avenue In a developed city like Roseville, it is often disruptive to widen a road. In cases where widening is not feasible, several new technologies, collectively known as Intelligent Vehicle Highway Systems (IVHS) can be an alternative way to improve traffic flow. IVHS includes techniques like ramp meters on freeways, changeable message signs, real-time Roseville Comprehensive Plan - 2003 Update Transportation - Page 19 of 28
