Moving the frontage road any closer to the exit ramp would result in trucks encroaching on <br />oncoming traffic. 1'he proposed curvature of the frontage road is designed to accommodate passenger <br />vehicles at approxitnately 15 mph. The close proximity of the frontage road and limited design speed <br />around the curve present challenges for the ramp intersection traffic signal operations including <br />inadequate visibility of the signal heads, restricted stacking space, and need for additional green time to <br />accommodate slower progression of vehicles. <br /> <br />The current design of the frontage road is very restrictive as proposed. Further design compromises <br />would result in an inadequate roadway configuration incapable of accommodating vehicular traffic safely. <br /> <br />I. <br />t <br />I:, ", <br />~ I <br /> <br />I' <br />;! <br />;' <br /> <br />~i <br />~,',I" <br />'I <br /> <br />~ <br /> <br />! <br />I <br />r <br />r <br />i" <br /> <br />~ : <br />
