Mr. John Weicht -7- May lIt 1994 e The top half of Figure 4 shows the existing and post-development traffic volumes at the T.R. 169/Main St. intersection with the right turn in/out access on T.R. 169 at Carson 51. The traffic volumes on all the approaches increase with the addition of the proposed development, which equates to 4.8 percent more traffic entering the intersection. This increase is smaller than that shown in Figure 4 due to vehicles exiting T.R. .169 prior t~ Main St. and then continuin~ w~t on ~ St. Once again, this is a relatlvely small mcrease and should have no slgmficant Impact on traffic operations of this intersection. The bottom half of Figure 4 shows the existing and post-development traffic volumes at the Main St./Carson St. intersection with the right turn in/out access on T.H. 169 at Carson St. Traffic volumes increase for the movements to and from Carson St. t as expected, and remain the same or decrease slightly on Main S1. The increases on Carson S1. will probably cause additional delays to vehicles using this streett especially to those exiting the area on Carson 51. ANALYSIS OF TRAFFIC NEEDS AT CARSON ST./MAIN ST. INTERSECTION . As discussed earlier, it is expected that higher traffic volumes will be experienced at this intersection following the proposed developmentts construction. In order to help alleviate possible conflicts the additional traffic may have at this intersectiont it is our recommendation that Carson St. be widened to add a right turn lane for the southbound traffic. 'rVe also reCommend the addition of a two foot striVed island to separate the northbound and southbound movements, as well as a stop lme for southbound vehicles to keep them from extending into the intersection while stopped. The addition of the striped island and the stop line will help reduce the likelihood of the type of accident described earlier from occurring. Figure 5 shows the concept layout plan for this intersection, incorporating our recommendations. With these iml?fovements, we feel the intersection will be able to adequately accommodate the additIonal traffic generated by the proposed development. CONCLUSIONS From the traffic analysis documented in this memorandum, we have established the foJ1owing conclusions: Under both roadway alternatives - 1) Carson St. remaining as a cul-de-sac and 2) Carson St. extended to provide right turn in and out access on T.R. 169 - it is expected that traffic volumes will increase at both the Carson St./Main St. and T.R. 169/Main St. intersections. The traffic volume increase at ttie T.H. 169/Main St. intersection is expected to be small and therefore no significant impacts are anticipated due to the additional traffic. Improvements are recommended at the Carson St./Main St. intersection to improve safety and reduce delay. The improvements include the addition of a right turn lane for southbound Carson St., the creation of a striped center island and the addition of a stop line for southbound Carson S1. .
