conflict. Converting this intersection to an all-way stop is not recommended because the volumes are significantly lower than desired for an all-way stop; volumes do not meet Manual on Uniform Traffic Control Devices (MUTCD)warrants for multi-way stop control. Additionally, the angle for vehicles approaching a stop sign from the north/west may lead to some drivers missing the sign. To slow traffic, the lanes on Main StreeUFront Street around the curve could be narrowed. When a lane is narrower, drivers tend to drive slower than if they were on a wider roadway. With a number of buses travelling through this intersection, the lane width would still need to remain wide enough for those large vehicles. Therefore, painting white edge lines will give the effect of a narrower lane. The road is currently over 20 feet wide at the ends of the curve. Painting 12-foot lanes will give drivers the feel that they should not take the curve fast and wide. Buses and large vehicles will still be able to traverse over the painted lines when needed to maneuver the curve. Another issue at this location is drivers crossing over the centerline when travelling southbound around the curve. One factor contributing to this is the presence of parking on the west side of 2"d Street along the curve. If a no parking zone were extended on the west side from the intersection to the north end of the curve, vehicles travelling south around the curve may not feel the need to cross the center line. An additional measure to keep drivers from crossing over the centerline as they travel around the corner would be placing flexible bollards along the centerline to guide drivers and enforce lane consistency. The bollards could be removed in the winter to accommodate snowplows. Turning movements were analyzed for school buses and full length semi-trailer trucks around this curve. With the addition of bollards, school buses would be able to navigate the curve without issue. Full sized semi-trailer trucks would not quite be able to do so as they currently need to cross over the centerline to make that turn. Though not seen during our observations, westbound vehicles traveling around the curve may also possibly cross over the centerline. Restricting parking on the north/east side of the curve may also be a consideration. A curve warning sign with an advisory speed plaque indicating a speed less than 30 mph may be appropriate. A speed study for the curve would be needed to determine the advisory speed limit. Patriot Avenue & Main Street This intersection is under signalized control with left turn lanes on all approaches and right turn lanes on the northbound and southbound approaches. The acceptable operation results with these lanes suggest an opportunity to change the traffic control, reduce the number of approach lanes, or do both. When considering a reduction in approach lanes, impacts to be considered include: Traffic Study 11 • . CONSULTING Pequof Lakes
