provide the Flower Street on -ramp will cause Fashion Square traffic to <br />use Flower Street or other residential streets to reach the northbound <br />57 Freeway on -ramp at Chapman Avenue. <br />Failure to provide the new Main Street slip ramp to northbound <br />1-5 would increase the southbound left turning movement to Edgewood by <br />688 veh in the peak period (240 veh/pk hour). An equal volume of <br />IL <br />freeway bound trips will use Main Street northbound through the La Veta <br />Avenue intersection to the westbound Route 22 on -ramp. In effect, the <br />entire northbound I-5 travel demand (1,376 vehicles in the 3 hour peak <br />period) would use Main Street thereby increasing turning movements all <br />along Main Street. Construction of the new Main Street slip ramp <br />eliminates left turns on Main Street and necessitates only right turns <br />t. <br />and use of thru lanes, both of which have substantially less impact on <br />critical intersection capacity. <br />This analysis has been qualitative rather than quantitative <br />because construction of the Broadway Overcrossing and the Owens Drive <br />P <br />connection to the east will significantly alter existing travel patterns <br />particularly in the vicinity of Main Street and the Santa Ana Freeway. <br />e. <br />Superimposing the freeway ramp traffic on existing intersection traffic <br />would not be realistic. In addition, several alternate routings to the <br />e: <br />freeways do exist. The travel patterns shown in Figure 27 are the most <br />direct routes to the freeways, but commuters will opt for alternates <br />(which avoid left turns) if substantial congestion is experienced at <br />their primary ramp location. As an example, many motorists may opt to <br />use the Route 22 Freeway for access to the I-5 and Route 55 Freeway <br />rather than Main Street particularly if the 1-5/Main Street interchange <br />is not improved. <br />It can be concluded from this qualitative analysis that <br />failure to provide the freeway ramp improvements proposed would severly <br />limit development opportunities in the entire Main Street/Town and <br />Country area. With regard to Fashion Square, the two new ramps on the <br />k <br />75DS48 <br />
